近来,日本市场上出现了一种用人工培育的光合细菌制成的饲料添加剂.这是一种稍带粘性的淡红色液体,在1毫升这样的菌液中,大约有50亿个个体为1微米左右的菌体.也就是说,在1升菌液中有5兆个光合细菌.用这种菌液混和在养鱼的饵料中获得了很好的促长和防病效果.这无疑是饲料添加剂的一块新开发的领域.本文着重介绍什么是光合细菌及其在水产养殖生产中的应用. Recently, a feed additive made from artificially cultivated photosynthetic bacteria has emerged in the Japanese market, a slightly viscous light-red liquid with approximately 5 billion individuals in 1 ml of this bacterium That is to say, there are 5 trillion photosynthetic bacteria in 1 liter of bacterium solution, and this bacterium solution has good growth-promoting and disease-prevention effect in the bait of fish culture. A newly developed field of feed additives.This article focuses on what is photosynthetic bacteria and its use in aquaculture production.
