Preparation method of solid photosynthetic bacterium

Abstract

The invention relates to the microbial preparation field, and specifically relates to a preparation method of a solid photosynthetic bacterium. More specifically, the method includes: taking soybean meal as a drying sorbent, selecting a liquid photosynthetic bacterium finished product with a bright purplish red color and a concentration of 3 billion / ml as a carrier, using the soybean meal to adsorb the liquid photosynthetic bacterium, and then performing drying to obtain a powdered solid photosynthetic bacterium product. The solid photosynthetic bacterium product produced by the invention is not susceptible to miscellaneous bacterium infection, and has good and stable quality, thus being able to be widely applied in aquaculture, farming, wastewater treatment, ornamental fish breeding and other fields. The product has a substantially extended storage and shelf life, and is also very convenient to transport, thus being worth vigorous promotion.

Description

technical field [0001] The invention relates to the field of microbial preparations, in particular to a method for preparing solid photosynthetic bacteria. technical background [0002] Photosynthetic bacteria are the oldest prokaryotic organisms with a primitive photosynthetic system on the earth. Photosynthetic bacteria are widely distributed in swamps, ponds, lakes, rivers, ditches, oceans and soils, and can tolerate high temperature, high salinity, low temperature and low salinity Photosynthetic bacteria can be found even in hot springs with a high temperature of 90°C, in salt lakes containing 30% salt, in deep seas as deep as 2,000 meters, and on the frozen coast of Antarctica. [0003] The applied research and productive research of photosynthetic bacteria have a history of thirty or forty years. In the 1960s, Japanese scientists observed the changes in the number of bacteria when high-concentration fecal sewage was placed naturally, and first revealed that organic se...
