Description
本発明は、微生物等に過熱水蒸気処理を施すことにより得られた微生物材料過熱水蒸気処理物と、過熱水蒸気処理していない微生物等と、を含む微生物由来還元性混合物に関する。
The present invention relates to a microorganism-derived reducing mixture containing a microorganism material superheated steam-treated product obtained by subjecting a microorganism or the like to superheated steam treatment, and a microorganism not subjected to superheated steam treatment.
フスマ、米ぬか等の農産副産物を有機栄養源として行う土壌還元消毒法は、高温期の地温を利用して湛水条件下で実施されており、微生物の増殖により酸化還元電位を低下させ土壌病原菌を消毒する手法である。ここで、通常の土壌還元消毒法では、フスマ、米ぬか等の有機物を１０ａあたり１ｔから２ｔも投入する必要があるため、多大な労力が必要となり農家の負担となっている。更に、土壌還元消毒法に使用されるフスマ、米ぬか等の有機物の価格は高騰しており、土壌還元消毒法の実施に当たって、コスト面での負担も増加している。このような理由から、フスマ、米ぬか等の有機物以外で土壌を還元することのできる資材が求められている。
The soil reduction disinfection method, which uses agricultural by-products such as bran and rice bran as an organic nutrient source, is carried out under submerged conditions using the soil temperature in the high temperature period. It is a method of disinfection. Here, in the usual soil reduction disinfection method, since it is necessary to introduce organic substances such as bran and rice bran as much as 1 to 2 tons per 10a, a great effort is required and a burden on the farmer. Furthermore, the prices of organic substances such as bran and rice bran used in the soil reduction and disinfection method have soared, and the cost burden has increased in the implementation of the soil reduction and disinfection method. For these reasons, there is a demand for materials that can reduce soil with organic substances other than bran and rice bran.
ところで、ビール工場等の食品製造工場から排出される廃酵母は、酵母エキスや酵母製剤の原料、家畜の飼料、肥料等として用いられる他は、焼却等の廃棄処理がなされている。また、酵母エキスを抽出した後に残る酵母細胞壁は、一部が健康食品、家畜用の飼料などに利用されているものの、他は主に廃棄されている。
しかしながら、これらの微生物由来材料の廃棄処理には、処理場への輸送費や処理コストがかかる。また、従来知られている酵母由来の上記の食品、飼料、肥料等では、廃酵母の発生量に対する利用量等に限界があり、廃酵母を付加価値の高い製品として提供可能な新たな用途が求められていた。
廃酵母を利用した新たな用途としては、例えば、国際公開第２０１０／１０４１９７号公報に、微生物又は微生物の成分を、酸素非存在下で過熱水蒸気処理をすることを特徴とする０ｍＶ以下の酸化還元電位を有する微生物由来還元性混合物の製造方法が開示されている。 By the way, waste yeast discharged from a food manufacturing factory such as a beer factory is used as a raw material for yeast extract and yeast preparation, livestock feed, fertilizer, etc., and is subjected to disposal processing such as incineration. Moreover, although some yeast cell walls remaining after extracting the yeast extract are used for health food, livestock feed, etc., others are mainly discarded.
However, disposal of these microorganism-derived materials requires transportation costs to the processing plant and processing costs. In addition, the above-mentioned foods, feeds, fertilizers, etc. derived from yeast have a limit in the amount of use with respect to the amount of waste yeast generated, and there is a new application that can provide waste yeast as a product with high added value. It was sought after.
As a new application using waste yeast, for example, in WO 2010/104197, a microorganism or a component of a microorganism is subjected to superheated steam treatment in the absence of oxygen, and is a redox of 0 mV or less. A method for producing a microorganism-derived reducing mixture having an electric potential is disclosed.

本発明の微生物由来還元性混合物を農業分野で利用する場合、これまでその有効性が示されている酵母由来成分を還元型で製造し、農作物の細胞内の酸化還元電位に近い酸化還元電位を有する状態で土壌に導入できるため、酵母由来成分が農作物に及ぼす効果を高めることができる。このため、微生物由来還元性混合物の利用により、生育促進、収量増加、植物の病害への抵抗性の向上等の効果を得ることができる。
また、本発明の微生物由来還元性混合物は、その還元性を利用して、土壌消毒技術として注目されている湛水還元技術に使用することができる。湛水還元技術は、水田のようにして圃場に水を張ることにより、水面下の土壌を還元状態にして土壌中の病害菌を減少させる方法であるが、大量の水が必要であること、長期間に亘り圃場に水を保持する必要があること、微生物を利用するためにその利用が高温期のみに限定されることなどから、その汎用性が乏しかった。更に、湛水を行うことにより、かえって有害菌が蔓延する例も知られていた。
しかしながら、本発明の微生物由来還元性混合物を含む組成物を湛水の際に土壌改良剤組成物として使用することにより、温度に関係なく、土壌中の酸化還元電位を－２００ｍＶ以下の電位に低下させることができる。即ち、本発明の微生物由来還元性混合物は、土質改良剤組成物を調製するために使用することができる。土質改良剤組成物を調製する場合、本発明の微生物由来還元性混合物に加えて、通常、土壌改良に供される腐植酸資材、ゼオライト、珪藻土、珪酸カルシウム、バーミキュライト、及びピートモス類を含有させてもよい。特に、微生物由来還元性混合物に加えて珪藻土を混合することにより、土質改良剤組成物の酸化還元電位を効果的に低下させることができる。この土質改良剤組成物を用いて土壌改良を行うことにより、生育促進や収量増加等の効果を見込むことができる。 When the microorganism-derived reducing mixture of the present invention is used in the agricultural field, yeast-derived components that have been shown to be effective so far are produced in reduced form, and an oxidation-reduction potential close to the intracellular oxidation-reduction potential of the crop is obtained.

Moreover, the microorganism-derived reducible mixture of this invention can be used for the flood reduction technique attracting attention as a soil disinfection technique using the reducibility. Drowning reduction technology is a method to reduce the pathogenic bacteria in the soil by reducing the soil under the surface by reducing the surface of the water by spreading water in the field like a paddy field, but a large amount of water is required, Since it is necessary to keep water in the field for a long period of time, and its use is limited only to the high temperature period in order to use microorganisms, its versatility was poor. Furthermore, there has been known an example in which harmful bacteria are spread by flooding.
However, by using the composition containing the microorganism-derived reducing mixture of the present invention as a soil conditioner composition during flooding, the oxidation-reduction potential in the soil is reduced to a potential of −200 mV or less regardless of the temperature. Can be made. That is, the microorganism-derived reducing mixture of the present invention can be used for preparing a soil conditioner composition.

更に、植物病害抵抗性向上剤組成物には、植物成長調節剤を添加することもできる。
一般に、生物は、生育環境の酸化還元電位の影響を受けることが知られており、酸化還元電位が高い環境を好む生物は好気的な環境を好み、酸化還元電位が低い環境を好む生物は嫌気的な環境を好むといいわれている。嫌気度の高い環境を好む生物として、有名なものとしては、一般的に培地の酸化還元電位が－３３０ｍＶ以下であることを要求するメタン菌を挙げることができる。他にも、一般的な硝化細菌、脱窒菌、硝酸還元菌などは、低い酸化還元電位の生育環境を要求する。一方、好気度の高い環境を好む生物としては、ほぼ全ての動物、ほとんどの真菌類、Bacillus属、Pseudomonas属等の一部の細菌類等を挙げることができる。
このように、生物にはそれぞれ、生育に好ましい酸化還元電位の領域があるため、土壌中の酸化還元電位を調整することにより、特定の微生物を活性化させたり不活性化させたりすることができる。本発明の微生物由来還元性混合物を用いて環境中の酸化還元電位を低く抑えることにより、好気的環境を好む微生物の活性を抑制することができると共に、嫌気的環境を好む微生物の活性を向上させることができる。 The microorganism-derived reducing mixture of the present invention can also be used for preparing a plant disease resistance improver composition.

In general, organisms are known to be affected by the redox potential of the growing environment. Organisms that prefer environments with high redox potential prefer aerobic environments, and organisms that prefer environments with low redox potentials. It is said to prefer an anaerobic environment. As well-known organisms that prefer environments with high anaerobic conditions, there can be mentioned methane bacteria that generally require that the redox potential of the medium be −330 mV or less. In addition, general nitrifying bacteria, denitrifying bacteria, nitrate-reducing bacteria, etc. require a low redox potential growth environment. On the other hand, examples of organisms that prefer a highly aerobic environment include almost all animals, most fungi, and some bacteria such as the genus Bacillus and Pseudomonas.
Thus, since each organism has a region of redox potential that is favorable for growth, it is possible to activate or inactivate specific microorganisms by adjusting the redox potential in the soil. . By suppressing the oxidation-reduction potential in the environment using the microorganism-derived reducing mixture of the present invention, the activity of microorganisms that prefer an aerobic environment can be suppressed and the activity of microorganisms that prefer an anaerobic environment can be improved.
