以過醋酸在動物養殖場中抑制病原性微生物的方法 Method for inhibiting pathogenic microorganisms in animal farms with peracetic acid

本發明有關以過醋酸在動物養殖場中抑制病原性微生物的方法。 The present invention relates to a method of inhibiting pathogenic microorganisms in an animal farm using peracetic acid.

傳統上動物養殖業在進行水處理之應用中,已在很早即開始使用抗菌劑類藥物以進行對於養殖池水、動物養殖、水產養殖等治療動物的疾病及環境之殺菌,這些抗菌劑包括β-內醯胺類抗生素(Beta-lactam)、胺基醣苷類抗生素(Aminoglycoside)、大環內酯類抗生素(Macrolide)、四環素類抗生素(Tetracycline)、氯黴素(Chloramphenicol)、奎諾酮(Quinolone)、磺胺類(Sulfonamides)等藥物;在這些類別藥物中,台灣現今核准使用於水產養殖之動物藥物計有安默西林(Amoxicillin)、安比西林(Ampicillin)、脫氧羥四環黴素(Doxycycline)、紅黴素(Erythromycin)、氟甲磺綠黴素(Florfenicol)、北里黴素(Kitasamycin)、林可黴素(Lincomycin)、歐索林酸(Oxolinic acid)、為歐索林酸衍生物之氟滅菌(Flumequine)、羥四環黴素(Oxytetracycline)、史黴素(Spiramycin)、屬磺胺劑類之磺胺一甲氧嘧啶(Sulfamonomethoxine)、磺胺二甲氧嘧啶(Sulfadimethoxine)、和甲磺綠黴素(Thiamphenicol)等;但,以動物養殖為例,在動物養殖業者用藥知識缺乏下,尤其是未經檢驗確定感染源下,任意連續施用相同類別之藥物造成交叉抗藥性問題,及長期使用下造成病原菌普遍對多數藥物產生抗藥性,致使藥物使用劑量不得不不斷地提高,到最後產生使用藥物無效的結果; 進一步,未遵守停藥期規定而造成藥物殘留的問題,更造成人們食用養殖動物後對健康的威脅。另外,養殖用水任意向外排放,造成包括沿海水域及內陸區域的嚴重污染。 Traditionally, in the application of water treatment in animal husbandry, antibacterial agents have been used very early to carry out sterilization of diseases and environments for therapeutic animals such as pond water, animal breeding, aquaculture, etc. These antibacterial agents include β. - Beta-lactam, Aminoglycoside, Macrolide, Tetracycline, Chloramphenicol, Quinolone ), sulfonamides (Sulfonamides) and other drugs; among these categories of drugs, Taiwan's current approval for aquaculture animal drugs are Amoxicillin, Ampicillin, Doxycycline , Erythromycin, Florfenicol, Kitasamycin, Lincomycin, Oxolinic acid, Oxolinic acid derivatives Flumequine, Oxytetracycline, Spiramycin, Sulfamonomethoxine, Sulfadimeth, Sulfonamide Oxine), and sulfomycin (Thiamphenicol), etc.; however, in the case of animal farming, in the absence of knowledge of animal husbandry medication, especially the unidentified source of infection, any continuous application of the same class of drugs caused crossover The problem of drug resistance, and long-term use, causing pathogens to become generally resistant to most drugs, resulting in a continuous increase in the dose of the drug, and ultimately the result of invalid use of the drug; Further, the problem of drug residues caused by failure to comply with the withdrawal period regulations has caused people to threaten their health after eating animals. In addition, aquaculture water is discharged arbitrarily, causing serious pollution, including coastal waters and inland areas.

以動物養殖為例,採用非上述藥物的化學殺菌劑是另一種選擇,但常用的四級胺對革蘭氏陰性菌殺菌力較差,且對池水中提供溶氧重要來源的藻類具有強烈毒性;醛類諸如甲醛和戊二醛則是致癌物,禁止使用於動物養殖場;氯化合物(諸如次氯酸)的使用會產生三氯甲烷致癌物;碘化合物諸如優碘對魚蝦具刺激性且對部份革蘭氏陰性菌殺菌力不佳。動物養殖場確實需要更安全且更具廣效效能的殺菌劑。 Taking animal breeding as an example, the use of chemical bactericides other than the above drugs is another option, but the commonly used quaternary amines have poor bactericidal power against Gram-negative bacteria and are highly toxic to algae which provide an important source of dissolved oxygen in the pool water; Aldehydes such as formaldehyde and glutaraldehyde are carcinogens and are prohibited for use in animal farms; the use of chlorine compounds such as hypochlorous acid produces chloroform carcinogens; iodine compounds such as iodine are irritating to fish and shrimp. Poor bactericidal power against some Gram-negative bacteria. Animal farms do require a safer and more versatile fungicide.

過醋酸具有的強烈殺菌力、廣效性及生物可分解的環保親和性,早時即使用在醫療器械(其包括塑膠製品)的高層次消毒,也有使用在食品加工廠做為在固體表面、容器和輸送管線的消毒清潔處理。 Peracetic acid has strong bactericidal power, broad-spectrum and biodegradable environmental affinity. It has been used in high-level disinfection of medical devices (including plastic products), and also used in food processing plants as solid surfaces. Disinfection and cleaning of containers and transfer lines.

過醋酸的製備可以醋酸、過氧化氫和水之混合溶液,或以固體諸如四乙醯乙二胺(tetraacetylethylenediamine,TAED)之類醯胺化合物與無機過氧化物在水中反應產生得到。過醋酸的水相/油相參與比例為98:2,為親水性良好的物質,但對疏水性物質滲透力較差,且過高的劑量會對水產養殖動物產生致命毒性,無法以高劑量以克服對油相的滲透(例如使用比利時的Solvay Interox S.A.公司生產之15%過醋酸溶液對屬於海水魚的細鱗鰈浸泡24小時的半數致死濃度LC50為98.7ppm(過醋酸濃度為14.8ppm));此外,池水中包括油脂的疏水性物質亦會影響過醋酸的殺菌效能。到目前為止,幾乎沒有相關之研究報告和文獻 及相關商品報導過醋酸在處理水產養殖池池水的殺菌用途。同樣的,亦無相關報導過醋酸在養殖池水、動物養殖等之殺菌用途。 The preparation of peracetic acid can be carried out by reacting a solution of acetic acid, hydrogen peroxide and water, or by reacting a guanamine compound such as tetraacetylethylenediamine (TAED) with an inorganic peroxide in water. The aqueous phase/oil phase of peracetic acid is 98:2, which is a hydrophilic material, but it has poor penetrability to hydrophobic substances, and too high a dose will cause fatal toxicity to aquaculture animals, and cannot be used at high doses. Overcome the penetration of the oil phase (for example, using a 15% peracetic acid solution produced by Solvay Interox SA of Belgium), the LC50 of the semi-lethal concentration of the seawater fish immersed for 24 hours is 98.7ppm (peracetic acid concentration is 14.8ppm) In addition, the hydrophobic substances in the pool water, including grease, also affect the bactericidal efficacy of peracetic acid. So far, there are few related research reports and literatures. And related commodities reported the use of acetic acid in the treatment of aquaculture pond water. Similarly, there is no report on the sterilization of acetic acid in culture ponds, animal breeding, etc.

針對此技藝之需要,本發明揭露一種以過醋酸進行抑制動物養殖場之水內及/或環境固體表面上的病原性微生物的方法,該方法包含對養殖場池水及/或環境固體表面投予:(1)經稀釋之過醋酸,使養殖場池水內及/或環境固體表面上之過醋酸濃度為0.0005至4.9ppm;和(2)濃度為經稀釋之過醋酸的濃度之0.001至60倍之包含至少9個碳原子的碳鏈之界面活性劑;其中經投予後之經稀釋之過醋酸與經稀釋之界面活性劑對養殖場池水及/或環境固體表面的接觸時間至少1分鐘。該包含至少9個碳原子的碳鏈之界面活性劑能增進過醋酸對動物養殖場中疏水性物質之滲透並進而增強過醋酸之抑制病原性微生物的能力。 In response to the needs of the art, the present invention discloses a method for inhibiting pathogenic microorganisms on the surface of water and/or environmental solids of an animal farm using peracetic acid, the method comprising administering to the pond water and/or environmental solid surface of the farm (1) The diluted peracetic acid is such that the concentration of peracetic acid in the pool water and/or on the surface of the environmental solid is 0.0005 to 4.9 ppm; and (2) the concentration is 0.001 to 60 times the concentration of the diluted peracetic acid. A surfactant comprising a carbon chain of at least 9 carbon atoms; wherein the contact between the diluted peracetic acid and the diluted surfactant to the farm pool water and/or the ambient solid surface is at least 1 minute. The surfactant comprising a carbon chain of at least 9 carbon atoms enhances the penetration of peracetic acid into hydrophobic materials in animal farms and thereby enhances the ability of peracetic acid to inhibit pathogenic microorganisms.

本發明發現雖然親水性良好的過醋酸對病原菌有良好抑制能力,但對疏水性物質之滲透性較差,但以經稀釋之過醋酸的濃度之0.001至60倍之包含至少9個碳原子的碳鏈之界面活性劑,可經由提昇過醋酸對疏水物質的滲透力而增強過醋酸的抑菌力。其中過醋酸的來源可由熟知的有機化學反應得到,但不限定為由過氧化氫、醋酸和水的溶液,也可以在酸的催化下以乙醛、乙醯氯、或乙酸酐經氧化作用產生的溶液,也可以為由N-醯胺化合物、過氧化物鹽及水所產生的水溶液得到。 The present inventors have found that although peracetic acid having good hydrophilicity has good inhibitory ability against pathogenic bacteria, it has poor permeability to hydrophobic substances, but contains carbon of at least 9 carbon atoms at a concentration of 0.001 to 60 times the concentration of diluted peracetic acid. The surfactant of the chain enhances the bacteriostasis of peracetic acid by increasing the penetration of peracetic acid into the hydrophobic material. The source of peracetic acid can be obtained by a well-known organic chemical reaction, but is not limited to a solution of hydrogen peroxide, acetic acid and water, or can be produced by oxidation of acetaldehyde, ethyl chloroform or acetic anhydride under acid catalysis. The solution may also be obtained from an aqueous solution produced from an N-guanamine compound, a peroxide salt, and water.

疏水物質包括含有或殘留有飼料油脂的養殖池水、飼料攪拌槽、飼料輸送管、與飼料供料槽、和欄舍 的固體表面等、細胞壁所含具有疏水性胜肽之聚醣的革蘭氏陽性菌和革蘭氏陰性菌、細胞壁含有含氮多醣的幾丁質的真菌、禽畜動物和魚類的皮膚、含有幾丁質的蝦類類外殼、及魚體皮膚潰瘍所產生疏水性物質等,但不限於前所述及的物質和器材設備。 Hydrophobic substances include culture pond water containing or containing feed fats and oils, feed agitation tanks, feed conveying pipes, feed tanks, and barns a solid surface, etc., a Gram-positive and Gram-negative bacteria containing a glycan of a peptide, a cell wall containing a chitin containing a nitrogen-containing polysaccharide, a skin of a poultry animal, and a fish, containing The chitin-like shell of the shrimp and the hydrophobic substance produced by the skin ulcer of the fish, but not limited to the materials and equipment mentioned above.

習知的方法以增加過醋酸濃度是可以提昇過醋酸本身的抑菌力並加速其抑菌速率,但由於過醋酸的毒性會引起禽畜動物呼吸道刺激和皮膚過敏,尤其是極低濃度下的過醋酸也可能會對水產養殖動物產生致命的毒性,且過低濃度的過醋酸往往對某些微生物無法發生有效的抑制作用。本發明發現使用濃度為經稀釋之過醋酸的濃度之0.001至60倍之包含至少9個碳原子的碳鏈之界面活性劑能促進經稀釋之過醋酸之抑菌力。 The conventional method to increase the concentration of peracetic acid can increase the antibacterial activity of peracetic acid itself and accelerate its antibacterial rate, but the toxicity of peracetic acid can cause respiratory irritation and skin irritation in livestock animals, especially at very low concentrations. Peracetic acid may also cause lethal toxicity to aquaculture animals, and too low concentrations of peracetic acid often do not effectively inhibit certain microorganisms. The present inventors have found that the use of a surfactant having a carbon chain of at least 9 carbon atoms at a concentration of from 0.001 to 60 times the concentration of the diluted peracetic acid promotes the bacteriostatic action of the diluted peracetic acid.

以下為以水產養殖場之應用為實施例,但本發明並不限於該實施例,而可應用於養殖池水、動物養殖,其相關實施例之環境以及其應用數據不再贅述。 The following is an example of the application of the aquaculture farm, but the present invention is not limited to the embodiment, but can be applied to culture pond water, animal breeding, the environment of the related embodiments and the application data thereof are not described again.

使用過醋酸抑制池水中病原性微生物是一種很好 的方法,過醋酸的水相/油相參與比例為98:2,為親水性良好的物質,但對疏水性物質之滲透性較差。在水產養殖池水中有許多疏水性物質會影響過醋酸之殺菌力,諸如飼料油脂,與治療魚蝦疾病時所使用包覆脂溶性藥物的魚油等,彼等是池水中主要常出現的疏水性物質來源;禽畜養殖場中疏水性物質來自飼料油脂,此會阻礙親水性的過醋酸與池水中微生物接觸,進而減低殺菌效果;當細菌性皮膚疾病發生時,例如親水性產氣單胞菌(Aeromonas hydrophila)、弧菌(Vibrio spp.)、滑走菌(Flexibacter & Cytophaga)常引發石斑魚的細菌性皮膚膿瘍,皮膚與肌肉中的脂肪成份和增生的黏液是過醋酸和魚體接觸的障礙;另外,蝦蟹出現體表外殼症狀時,外殼所含疏水性幾丁質的長鏈多醣也是過醋酸與蝦蟹接觸的障礙;再者,過醋酸對水生養殖動物的毒性特性是提高使用劑量上的限制。 It is a good idea to use peracetic acid to inhibit pathogenic microorganisms in pool water. In the method, the aqueous phase/oil phase of peracetic acid has a ratio of 98:2, which is a hydrophilic substance, but has poor permeability to hydrophobic substances. There are many hydrophobic substances in the aquaculture pond water that affect the bactericidal power of peracetic acid, such as feed fats and oils, and fish oil coated with fat-soluble drugs used in the treatment of fish and shrimp diseases. They are the most common hydrophobicity in pool water. Source of matter; the hydrophobic material in poultry farms comes from feed oils, which prevents hydrophilic peracetic acid from coming into contact with microorganisms in the pool water, thereby reducing the bactericidal effect; when bacterial skin diseases occur, such as hydrophilic Aeromonas (Aeromonas hydrophila), Vibrio spp., and Flexibacter & Cytophaga often cause bacterial skin abscess in grouper, and fat and hyperplastic mucus in skin and muscle are obstacles to contact between acetic acid and fish. In addition, when the shrimp and crab have symptoms of surface shell, the long-chain polysaccharide containing hydrophobic chitin in the outer shell is also a barrier to the contact between peracetic acid and shrimp and crab; in addition, the toxicity characteristic of peracetic acid to aquatic animals is to increase the dosage. limits.

實際上,以海水中數量為2 x 105的溶藻弧菌測試過醋酸的殺菌力時,發現過醋酸濃度從0.015ppm提高10倍至0.15ppm都無法在2小時內殺死溶藻弧菌,但過醋酸濃度在0.125ppm就會造成石斑魚之2吋魚苗出現沉入池底無法上浮現象,經病理解剖可發現鰓部和肝臟嚴重受損,進而迅速死亡。雖然長碳鏈的界面活性劑對魚蝦有強刺激性,但本發明發現使用包含至少9個碳原子的碳鏈之界面活性劑與過醋酸,在適合的浸泡時間下,可安全有效地去除池水中病原性微生物;例如,在2吋半魚苗的海水池中,對稀釋為0.05ppm過醋酸溶液加入稀釋為0.6ppm之12倍過醋酸濃度的月桂基硫酸鈉後,可在6小時內將溶藻弧菌全數殺滅,池水在6小時後進行換水,魚體未出現損傷。 In fact, when the bactericidal power of acetic acid was tested in 2 x 10 5 of Vibrio alginolyticus in seawater, it was found that the peracetic acid concentration increased by 10 times to 0.15 ppm from 0.015 ppm, and Vibrio alginolyticus could not be killed within 2 hours. However, if the concentration of peracetic acid is 0.125ppm, it will cause the 2 carp fry of the grouper to sink into the bottom of the pool and cannot rise. The pathological anatomy can be found that the ankle and liver are severely damaged, and then die rapidly. Although the long carbon chain surfactant is highly irritating to fish and shrimp, the present inventors have found that the use of a surfactant comprising a carbon chain of at least 9 carbon atoms and peracetic acid can be safely and effectively removed at a suitable soaking time. Pathogenic microorganisms in pool water; for example, in a seawater tank of 2吋 half fish fry, after adding a dilution of 0.05ppm peracetic acid solution to a sodium dilauryl sulfate diluted to a concentration of 0.6ppm 12 times peracetic acid, it can be used within 6 hours. The Vibrio alginolyticus was completely killed, and the pool water was changed after 6 hours, and the fish body was not damaged.

另外,以細菌結構的微觀角度,水產養殖動物常發生的細菌疾病,來自革蘭氏陽性菌者計有諸如:Clostridium botulinm(肉毒桿菌症)、Renibacterium salmoninarum(細菌性腎臟病;Bacterial Kidney Disease/BKD)、Staphylococcus sp.(葡萄球菌症;眼病)、Streptococcus sp.(鏈球菌症)、Enterococcus/Lactococcus sp.(鏈球菌症)、Lactobacillus sp.(假腎病)、Mycobacterium marinum/Mycobacterium sp.(結核分枝桿菌症)、Nocardia asteroids/Nocardia kampachi(努卡氏菌症)、Staphylococcus epidermidis(表皮葡萄球菌)等;來自革蘭氏陰性菌計有諸如:Flexibacter/Cytophaga/Flavobacterium(鰓病;柱狀病;冷水病)、Edwardsiella ictaluri(河鯰腸道敗血症)、E.tarda(鰻肝腎病),Yersinia ruckeri(紅嘴病)、Citrobacter spp.、Pasteurella piscicida(Photobacterium damsela subsp.piscicida,巴氏桿菌症)、Serratia sp.(敗血症)、Pseudomonas fluorescens(鯉全身性敗血症)、Ps.Anguilliseptica(鰻赤點病)、Vibrio sp.(弧菌症)、Aeromonas salmonicida(癤瘡病)、Aer.hydrophila(鰻赤鰭病;出血性敗血症)、Aer.Sobria/Chlamydiaceae/Rickettsiales(絕對體內寄生;敗血症)等。這些革蘭氏陽性菌和革蘭氏陰性菌之細胞壁中都含疏水性胜肽聚醣成份,其中革蘭氏陽性菌具較厚之細胞壁且含高含量之胜肽聚醣;真菌細胞壁則含有含氮多醣的幾丁質;分枝桿菌和努卡氏菌之細菌壁則含有高達20至30個碳之長鏈具蠟質特性的分枝酸,使其相對於親水性的過醋酸猶如一層疏水性屏障,其中分枝桿菌已在鱉養殖場中出現嚴重感染現象;常見之魚皮膚症 狀係諸如:(1)淡水及淡鹹水魚在12℃至18℃水溫常出現真菌類的水黴菌症Oomycetosis(Achlya and Saprolegnia),會附著在體表出現黏黏的棉絮狀物;(2)屬革蘭氏陰性菌的弧菌造成石斑魚及包括金目鱸、七星鱸和加州鱸等的皮膚白點症狀的菌斑,包含病原菌和黏液等物質,其中石斑魚2吋魚養殖場多採極高密度養殖,並以每2小時排流水比進行換水方式,每一次換水就是一次新的感染的開始,讓弧菌皮膚病變得更棘手;(3)屬革蘭氏陰性菌的非典型產氣單胞菌感染症,出現症狀為皮膚潰瘍症狀。以上的皮膚症狀都有黏質棉絮狀物(水黴菌症)、細菌釋放出蛋白質溶解脢分解肌肉蛋白質所產生的胜肽物質,伴隨油脂與體表增生的黏液等共同皮膚潰瘍特徵,這是屬於水中微生物致使魚隻體表的感染,而魚苗階段餵食赤尾青和豐年蝦幼蟲等活體餌料,甚至是餵食肉食性養殖魚類的下雜魚,都可能帶有病原菌,會造成魚隻自體內向體表的感染症狀。傳統上餵食抗生素和使用抗生素進行藥浴是常採取的方法,但因為長期使用造成多數病菌產生嚴重的抗藥性,即使提高用量也無法殺死病菌,且尤其是浸泡過抗生素的魚苗和蝦苗體質較不良,當放養至室外魚池容易造成適應不良而死亡。在解決這些問題上,在池水中使用益生菌,以優勢數量的有益菌分解有機廢棄物和抑制病原菌的生長是很好的方法,但大量的益生菌反而會成為病毒在水中生存的載體,進而助長病毒感染的機會,使得益生菌的使用成為有益和有害之衝突性做法。過醋酸對於水中養殖魚蝦及藻類的毒性相對其他殺菌劑低得很多,降解後產生無害的醋酸、水和氧氣,適合使用在養殖池的殺菌淨化用途;但池水包括油脂、細胞壁所含具有疏水 性胜肽之聚醣的革蘭氏陽性菌和革蘭氏陰性菌、細胞壁含有含氮多醣的幾丁質的真菌、含有幾丁質的蝦類類外殼、及魚體皮膚潰瘍所產生疏水性物質,都是造成工作濃度最多只有幾個ppm的過醋酸(濃度過高對水中動物會產生毒性反應)無法發揮效能的主要原因。 In addition, bacterial diseases often occur in aquaculture animals from the microscopic point of bacterial structure, such as: Clostridium botulinm (botulinum bacillus), Renibacterium salmoninarum (bacterial kidney disease; Bacterial Kidney Disease/) BKD), Staphylococcus sp. (staphylococcus; eye disease), Streptococcus sp. (streptococcus), Enterococcus/Lactococcus sp. (streptomycin), Lactobacillus sp. (pseudylosis), Mycobacterium marinum/Mycobacterium sp. Mycobacteria), Nocardia asteroids/Nocardia kampachi (Norcaosis), Staphylococcus epidermidis (S. epidermidis), etc.; from Gram-negative bacteria such as: Flexibacter/Cytophaga/Flavobacterium (ricky; columnar disease) Cold water disease), Edwardsiella ictaluri, E. tarda, Yersinia ruckeri, Citrobacter spp., Pasteurella piscicida (Photobacterium damsela subsp. piscicida, Pasteurella) , Serratia sp., sepulmonas fluorescens, Ps. Anguilliseptica . Vibrio sp (Vibrio Disease), Aeromonas salmonicida (furunculosis), Aer.hydrophila (eel red fin disease; hemorrhagic septicemia), Aer.Sobria / Chlamydiaceae / Rickettsiales (absolute endoparasitic; sepsis) and the like. The cell walls of these Gram-positive and Gram-negative bacteria contain hydrophobic peptide glycan glycosides, of which Gram-positive bacteria have thicker cell walls and contain high levels of peptide peptidoglycan; fungal cell walls contain The chitin of the nitrogen-containing polysaccharide; the bacterial wall of the mycobacteria and the nucleus bacteria contains a long chain of waxy properties of up to 20 to 30 carbons, making it a layer relative to the hydrophilic peracetic acid. Hydrophobic barrier, in which mycobacteria have been found to cause serious infections in alfalfa farms; common fish skin disease Such as: (1) freshwater and brackish water fish often appear fungus-like watery mildew Oomycetosis (Achlya and Saprolegnia) at 12 ° C to 18 ° C water temperature, will adhere to the surface of the sticky sticky cotton; (2 ) Vibrio, which is a Gram-negative bacterium, causes groupers and plaques including white-spotted symptoms such as gold mites, seven-star mites and California cockroaches, including pathogens and mucus, among which grouper 2 carp farms are highly dense. Breeding, and changing the water ratio every 2 hours, each time changing water is the beginning of a new infection, making Vibrio skin disease more difficult; (3) Atypical gas producing unit of Gram-negative bacteria Infected with bacteria, the symptoms are symptoms of skin ulcers. The above skin symptoms are characterized by sticky cotton batt (water mold), bacteria releasing protein peptides, protein peptides produced by the decomposition of muscle protein, and common skin ulcer characteristics such as mucus of oil and body surface hyperplasia. Microorganisms in the water cause infection on the surface of the fish, while live feeds such as red-tailed green and brine shrimp larvae are fed at the fry stage, and even the next fish that feed on carnivorous farmed fish may carry pathogenic bacteria, which may cause the fish to be in vivo from the body. Symptoms of infection in the table. Traditionally, feeding antibiotics and using antibiotics for medicated baths is a common method. However, most of the bacteria cause serious drug resistance due to long-term use. Even if the dosage is increased, the bacteria cannot be killed, and especially the fry and shrimps that have been soaked with antibiotics. Poor, when stocked to an outdoor fish pond, it is easy to cause maladaptation and death. In solving these problems, it is a good method to use probiotics in pool water to decompose organic waste with a beneficial amount of beneficial bacteria and inhibit the growth of pathogenic bacteria, but a large number of probiotics will become carriers of virus survival in water, and then The opportunity to promote viral infection makes the use of probiotics a useful and harmful conflicting practice. Peracetic acid is much less toxic to fish, shrimp and algae in water than other fungicides. It produces harmless acetic acid, water and oxygen after degradation. It is suitable for sterilization and purification in culture ponds. However, pool water includes oil and water. Gram-positive and Gram-negative bacteria of the glycopeptide of the peptide, the chitin fungus containing the nitrogen-containing polysaccharide on the cell wall, the shell of the shrimp containing the chitin, and the hydrophobicity of the skin ulcer of the fish Substances are the main cause of the inability to perform peracetic acid (the concentration of which is too toxic to animals in water) at a working concentration of at most a few ppm.

而禽畜養殖動物常發生的細菌疾病,來自革蘭氏陽性菌者計有諸如:Staphylococcus aureus(金黃色葡萄球菌)、Streptococcus faecalis(糞腸球菌)等來自革蘭氏陰性菌計有諸如:Pssuedomonas aeruginosa(綠膿桿菌)、Salmonella typhimurium(鼠傷寒桿菌)、Salmonella choleraesuis(豬霍亂桿菌)、Bacillus cereus(臘桿菌)、E.coli(大腸桿菌)等;來自真菌計有諸如:Candida albicans(白色念珠球菌)、Trichophylton mentagrophytes(鬚瘡小芽胞癬菌)、Aspergillus fumigatus(薰烟色麴菌)、A.flavus(黃麴菌)、Penicillium sp.(盤尼西林菌屬)、Scopulariopsis sp.(小帚樣黴菌屬)等,這些細菌的細胞壁中同樣都含有胜肽聚醣成份,再加上環境表面上的油脂髒污等,都是能影響過醋酸殺菌力的疏水性物質。 Bacterial diseases often occur in poultry-bred animals, such as: Staphylococcus aureus (Staphylococcus aureus), Streptococcus faecalis (E. faecalis), etc. from Gram-negative bacteria such as: Pssuedomonas Aeruginosa, Pseudoella typhimurium, Salmonella choleraesuis, Bacillus cereus, E. coli, etc.; Cocci, Trichophylton mentagrophytes, Aspergillus fumigatus, A. flavus, Penicillium sp., Scopulariopsis sp. Dependent), etc., these bacteria also contain the peptide glycopeptide in the cell wall, and the grease on the surface of the environment is a hydrophobic substance that can affect the bactericidal power of acetic acid.
