摘　　要：为梳理耐盐细菌研究进展,分析属种存在种间多样性的原因并预测耐盐菌研究主要趋势,比较了B.haloduransC-125,MIR32,DSM497,XJU-1,XJU-80等亚种在物种进化、代谢生理、遗传和生物多样性方面的差异,并进行总结归纳.结果表明,在同一自然环境下,同一物种也可以演化为不同的亚种.基因改变背景下的环境胁迫是种间多样性的可能原因.筛选、改良菌株并建立功能菌株库是耐盐菌今后研究的主要趋势.In order to analyze the reasons of species diversity and predict the main research trends in the future with summarizing the research progress of B.halodurans,compares and summmarises the differences of species evolution,metabolic physiology,genetics and biodiversity among B.halodurans C-125,MIR32,DSM497,XJU-1 and XJU-80.The result shows that the same species could evolve into different subspecies under the same natural environment.The environmental stress under the background of gene change could be the the cause of interspecific diversity,and the research trend is to establish the functional strain bank of halotolerant bacteria with isolating and improving it.
