Description
技术领域
本发明属于生物农药研究领域,特别涉及一株抗生链霉菌及其代谢产物的制备以及其在抗病菌方面的应用。
背景技术
随着广谱抗生素及免疫抑制剂的广泛应用和侵入性治疗方法的开展,新的真菌病不断出现,一些古老的真菌病发病率开始上升,尤其是机会性真菌感染日益增多。真菌感染(特别是侵入性真菌感染)的发生率不断增大,对人类健康造成了严重危害。人类的真菌感染可分为3种:浅部真菌病、深部真菌病和系统性真菌病(Garber,2001),其中最严重的、可危及生命的真菌感染是系统性真菌病(Meis,2001)。深部真菌病的病原菌主要是念珠菌属,尤其是白色念珠菌(Candida albicans)。它在念珠菌所有种中致病力最强,一旦机体的免疫力下降或者正常的菌群平衡被破坏,它就会在粘膜下大量繁殖,侵入深层组织,引起系统性念珠菌感染(Maertens et al.,2001)。医院真菌感染中占第一位的是念珠菌感染,感染后造成病死率达21%,念珠菌几乎可以侵犯全身所有脏器,各种念珠菌仍是造血干细胞移植最常见的真菌感染源(周绮等,2000)。尽管机体终生都被白色念珠菌这种机会性致病菌致敏,但是并没有因此发展成免疫耐受,所以念珠菌感染的发病率呈不断上升趋势,在免疫抑制患者中念珠菌的发病率列居第一位(Radentz,1989)。近20年来白色念珠菌感染增长了40倍以上,已成为医院感染的主要死亡原因之一(廖万青,1985)。因此,寻找念珠菌新生物药剂十分有意义。
辣椒和黄瓜炭疽病是生产上普遍发生且危害严重的真菌病害,可造成烂叶、烂果、植株死亡。目前生产上主要利用多菌灵、代森锰锌等化学药剂进行防治,但农药残留及环境污染等负面效应也逐步增长。因此,寻找防治炭疽病新生物药剂十分必要。

实施例2:拮抗海洋放线菌的筛选、分离和鉴定
1、拮抗海洋放线菌的筛选和分离
1.1供试菌株及培养基:以白色念珠菌(Candida albican)(购于广东省微生物研究)作为指示菌,测定所分离的792株放线菌对白色念珠菌的抑制活性,以从中筛选出对念珠菌抑制活性最强的菌株。用于放线菌培养所用培养基为高氏一号培养基(具体配方如实施例1中所述);用于白色念珠菌培养的培养基为马丁培养基(配方为:葡萄糖20g,蛋白胨5g,酵母浸膏4g,K2HPO4·7H2O 0.63g,MgSO4·7H2O 1.8g,琼脂15g,加水定容至1000mL)。
1.2菌株的活化:按以上配方制备相应的培养基,将锥形瓶中的培养基加热溶解后倒入直径为9cm培养皿中,制备得到培养基平板。分别挑取保存于4℃冰箱的放线菌接种于高氏一号培养基平板上,置于28℃恒温培养箱中培养3~5d。
1.3菌株筛选
1.3.1初筛:采用纸片扩散法(Kirby Bauer,KB法)(Hunfeld,2001)测定样品对念珠菌抑制活性。马丁固体培养基倒平板,接种0.1mL(浓度为1*106cfu/ml)白色念珠菌液,均匀涂布。用无菌镊子将含放线菌液的滤纸片(直径6mm)平整的贴在平板表面。37℃培养1d后,测量抑菌圈直径,三次重复。初筛结果如表1所示(表中菌株名称均为自命名)。
表1抗白色念珠菌的活性菌株的初筛结果
1.3.2复筛:选取初筛效果好的放线菌株(对念珠菌抑菌圈直径>15mm)(见表1),将菌种在高氏一号固体培养基复壮培养。培养2代以后,用无菌打孔器打取直径6mm的菌块,置与涂布有白色念珠菌的马丁培养基中。37℃培养1d后,测量抑菌圈直径,三次重复。
复筛是选取抑菌圈直径15mm以上的菌株,其中以菌株PPI-16对白色念珠菌抑菌效果最好(见表2),对念珠菌抑菌圈直径为20.3mm。
表2抗白色念珠菌的活性菌株的复筛结果
菌株名称 | 抑菌圈直径(mm) | 菌株名称 | 抑菌圈直径(mm) |
H122-01 | 19.3±0.12b | H75-11 | 15.1±0.12f |
H74-21 | 16.4±0.09d | H122-02 | 15.9±0.09e |
200-09 | 17.5±0.21c | PPI-16 | 20.3±0.13a |
注:表内数据为3次重复平均值±SE,采用DPS进行方差分析,相同字母者表示在5%水平差异上不显著。
通过以上方法,从分离获得的6株(对念珠菌抑菌圈直径15mm以上的菌株)放线菌中复筛出一株对白色念珠菌抑菌能力较强的菌株PPI-16。
2、菌株PPI-16的鉴定
2.1形态观察
采用平皿插片法观察菌株的形态特征(阎逊初,1992)。将试验菌株接种在合成淀粉、克氏、察氏、葡萄糖天门冬素琼脂和马铃薯块及高氏一号等7种固体培养基上,插片,28℃培养7~20d。观察并记录生长情况、基内菌丝、气生菌丝和可溶性色素的颜色,同时取出插片,用光学显微镜观察气丝、基丝形态以及是否有横隔、断裂、膨大等特征。选取培养物经固定、脱水等处理后,扫描电镜观察并照相。
结果如图1和2所示:图1为抗生链霉菌PPI-16的孢子,图2为抗生链霉菌PPI-16的孢子丝。该菌株在高氏一号琼脂培养7~10d后,基内菌丝和气生菌丝丰茂,基丝不断裂,孢子丝着生在气生菌丝上,孢子丝柔曲,孢子光滑呈圆柱形,成熟的孢子链孢子个数在8个左右,没有观察到孢囊、孢核等结构。
2.2生理生化特征
按照链霉菌常规鉴定方法对菌株PPI-16进行鉴定,具体为:参考Lechevalie的方法(Lechevalier et al,1980)测定菌株的明胶液化、淀粉水解、牛奶的凝固与胨化、纤维素水解、碳源利用等特性,同时以抗生链霉菌(S.antibioticus EF063450)和灰红链霉菌(S.griseoruber AB184209)(均来源于广东省微生物研究所)为对照。
结果如表3所示:结果表明,PPI-16能使明胶液化,能水解淀粉,在纤维素上不生长,牛奶不胨化,也不液化,不产黑色素,能利用6种碳源。

将该序列与GenBank中相关数据进行BLAST相似性分析,搜索得到相似性序列84个,选取其中与PPI-16的16S rDNA序列相似性较高的9个典型菌株序列进行比对。这些菌株如表4所示:
表4 GenBank中与PPI-16相似的菌株

根据放线菌和链霉菌的分类鉴定手册,菌株PPI-16的形态特征、培养特征(孢子丝短而直、孢子是长圆柱形和表面光滑)及生理生化特性表现出链霉菌属的典型特征,归于金色类群。与9株同源率最高的链霉菌属菌株的16S rDNA进行构建系统发育树,菌株PPI-16与S.antibioticus EF063450处于同一分枝,亲缘关系最近,同源性高达99.9%,但其在培养特征、生理生化特征上与Streptomyces antibioticus有较大差异,故鉴定PPI-16为链霉菌金色类群新种抗白色念珠菌链霉菌Streptomyces antialbonostocticus。
表5抗白色念珠菌链霉菌与抗生链霉菌和灰红链霉菌的比较
