山东花生根瘤菌遗传多样性及高效共生固氮菌株的筛选

, 2016
山东省是我国花生种植和生产的主要地区，其花生根瘤菌遗传多样性和高效共生菌株种质资源较为丰富。为揭示山东省花生根瘤菌种群结构和遗传多样性，本研究从山东省10个县市采集新鲜的花生根瘤分离出根瘤菌，对菌株的16S rRNA基因、持家基因（recA、atpD、glnII）序列进行系统发育分析以确定根瘤菌的系统发育地位，同时对共生基因nifH、nodC序列进行系统发育分析，并通过温室盆栽接种实验筛选高效共生固氮根瘤菌菌株。 从10个县市采样点共分离到345株花生根瘤菌菌株 ...

96孔板高通量选育嗜线虫致病杆菌高产帕克素菌株

, 2013
帕克素（pekingmycin）是嗜线虫致病杆菌北京变种Xenorhabdus nematophilus var. pekinense CB6菌株代谢产生的广谱抗生素。研究证明帕克素对马铃薯晚疫病和辣椒疫病均具有较好的田间控制效果。为了进一步提高帕克素产量，为实现产业化奠定基础，本文首次用96孔板高通量筛选技术进行了帕克素高产菌株的筛选。将原始菌株CB6用紫外、微波和亚硝基胍诱变后在96孔板固体培养基上培养72 h，35%甲醇浸提24 h ...
