光合细菌(Photosynthetic Bacteria,简称PSB)是一类能够利用光能作为能源进行生长和繁殖的细菌的总称。它隶属于细菌门、真菌纲、红螺菌目。红螺菌目可分为二个亚目,三个科和十八个属。目前都已分离到纯种。当前在水产养殖业上使用的主要是红螺菌科的一类细菌。 一、光合细菌的生态特性 光合细菌主要生活在水田、浅的池塘、污浊的水体中。在氧气含量有限而光线能到达的沟渠、稻田以及鱼池的表层水、泥中,出现数量较多,可达10~5—10~7个菌体/毫升。而在氧气充足的富营养化池塘和江河水体中却较
Photosynthetic bacteria (PSB) are a group of bacteria that can use light energy to grow and multiply as an energy source. It belongs to the bacteria door, fungi, red spirochaetes. Rhodospirillum can be divided into two sub-orders, three families and eighteen genera. Purebreds have now been separated. Currently used primarily in the aquaculture industry is a family of Rhodospiridae bacteria. First, the ecological characteristics of photosynthetic bacteria Photosynthetic bacteria mainly live in paddy fields, shallow ponds, dirty water. Oxygen content is limited and light can reach the ditches, paddy fields and fish ponds in the surface water, mud, appeared in large numbers, up to 10 ~ 5-10 ~ 7 cells / ml. In the oxygen-rich eutrophic ponds and river water is more
