海洋细菌获得某种抗噬菌体感染机制后,新陈代谢能力往往有所下降,使得它们和野生型菌株可以同时共存,从而增加了微生物群落结构的多样性。此外,海洋中普遍存在的中尺度涡旋由于对深层海水的扰动作用也影响着微生物群落结构与功能。作者采用蛋白质组学技术,对一株海洋玫瑰杆菌RoseobacterdenitrificansOCh114抗噬菌体感染机制以及南海冷涡对微生物群落结构与功能的影响进行了研究。 我们利用分离自南海的一株玫瑰杆菌噬菌体RDJLΦ1,在其强胁迫诱导下获得一株对RDJLΦ1感染具有抗性的R.denitrificansOCh114突变株(M1),进而对该突变株抵抗噬菌体感染的作用机制进行了研究...Obtaining resistance to phages is often accompanied by a decrease in the competitive ability of the bacterial cell, thus the trade-off between resistance and competitiveness can allow the stable coexistence of sensitive and resistant bacteria, and modify the microbial community composition. Furthermore, as a result of mesoscale eddy perturbations in the ocean, deep-water was brought up, causing a ...学位:理学硕士院系专业:海洋与环境学院环境科学与工程系_环境科学学号:2262007115234
