具有III型分泌系统的Pseudomonas moraviensis FP1761植物益生功能及其全基因组分析
摩拉维亚假单胞菌 生物防治 植物益生菌 全基因组分析 III型分泌系统
2020/12/24
本研究从节瓜根际分离到一株具有防病促生功能的荧光类假单胞菌FP1761。该菌株对部分植物病原真菌和细菌具有拮抗能力,能够解钾、解有机磷和无机磷,可产生氨、蛋白酶、嗜铁素、吲哚乙酸。生物测定表明菌株FP1761可显著促进小麦生长。生理生化、平均核苷酸相似度、16S rDNA和多基因分析将FP1761鉴定为摩拉维亚假单胞菌(Pseudomonas moraviensis)。菌株FP1761基因组草图全...
梨灰霉病菌拮抗细菌Pseudomonas extremorientalis的鉴定、发酵条件优化及防效评价
梨 灰葡萄孢 Pseudomonas extremorientalis 鉴定 发酵条件 防效
2019/12/30
灰霉病是梨贮藏期的主要病害，发病率高，为害严重。为了有效控制该病害发生，利用平皿稀释法从梨根际土壤中分离内生细菌，并采用琼脂平板扩散法进行抑菌活性初筛，筛选出1株拮抗细菌L21，基于形态特征、生理生化特性及16S rRNA和gyrB序列分析，鉴定为Pseudomonas extremorientalis。采用生长速率法测定菌株L21的无菌发酵液对12种病原真菌均有抑制作用，采用Salkowski比...
