Algicidal bacteria against Alexandrium tamrense Study of culturable bacteria diversity and chitin degrading bacteria in South China Sea (SCS)

Abstract

本论文分离并鉴定了9株塔玛亚历山大藻杀藻细菌,研究了其杀藻方式,构建了其中5株杀藻细菌的基因组文库;从南海水样和沉积物样品中进行了细菌的分离和鉴定,并对其中两株几丁质降解菌的特性进行了研究;获得主要结果如下: 从东海赤潮高发区分离并筛选到9株塔玛亚历山大藻杀藻菌,16SrDNA序列分析表明它们分别属于假交替单胞菌属(SP31、SP44)、交替单胞菌属(DH12、DH46)、Idiomarina属(SP96)、弧菌属(DH47、DH51)、盐单胞菌属(DH74、DH77)。对它们的杀藻方式研究表明,这些杀藻细菌都是通过间接方式杀藻,即通过产生胞外杀藻活性物质来杀死藻细胞,直接加入细菌细胞并不产...As part of efforts to enhance the strategies employed to manage and mitigate algal blooms and their adverse effects, algicidal bacteria have shown promise as potential suppressors of these events. Nine strains of bacteria algicidal against the toxic dinoflagellate, Alexandrium tamarense, were isolated from the Donghai Sea area, China. Sequence analysis of 16S rDNA showed that all the algicidal bac...学位:博士后院系专业:海洋与环境学院环境科学与工程系_环境科学学号:BH1700019
