环境是一切生命机体生活、生存的场所,生物必须与环境建立不可分割的联系。微生物的生命活动也不能离开环境而存在。人类在生产和生活过程中,排出污水,废物中带有大量的致病微生物,在一定的条件下,可造成环境的严重污染,甚至引起疾病的流行。而微生物对环境的反作用,除了维持自然界物质循环和自然界的自净作用之外,在环境保护中,它们也是积极的参与者。60年代中期Stolp等发现的细菌寄生菌——噬菌蛭弧菌(Bdellovibrio bacterio-vorus,以下简称蛭弧菌),就是一类专门捕食细菌的寄生物。研究证明,蛭弧菌能清除环境水源中许多不同种属的病原菌,被认为
Environment is the place where all living organisms live and survive. Creatures must be inextricably linked with the environment. Microbial life activities can not leave the environment and exist. Human beings in the process of production and life, sewage discharge, waste with a large number of pathogenic microorganisms, under certain conditions, can cause serious environmental pollution, and even cause the epidemic. The adverse effects of microorganisms on the environment, in addition to maintaining the natural circulation of the material and nature’s self-purification, in the environmental protection, they are also active participants. The bacterial parasite Bdellovibrio bacterio-vorus (Bdellovibrio bacterio-vorus), discovered by Stolp et al. In the mid-1960s, is a type of parasites that specialize in preying on bacteria. Studies have shown that Bdellovibrio can eliminate many different species of pathogens in environmental water sources, is considered
