Preparation method of solid photosynthetic bacterium

Abstract

The invention relates to a preparation method of a solid photosynthetic bacterium. The preparation method comprises the specific following steps: firstly amplifying the photosynthetic bacterium selected as a vector, absorbing the strain with a super absorbent resin selected as a solidifying agent and solidifying together to obtain the solid photosynthetic bacterium strain. Through the implementation of the preparation method disclosed by the invention, the prepared solid photosynthetic bacterium strain is not easily infected with heterogeneous bacteria, is stable, has good quality and can be widely in fields such as farming, aquaculture, food processing and environmental protection. The storage period and quality guarantee period of the prepared solid photosynthetic bacterium product are greatly prolonged. Meanwhile, the prepared solid photosynthetic bacterium is very convenient to transport and circulate. During the implementation of the preparation method, super absorbent resin with relatively high water absorption capacity is applied as the solidifying agent, the consumption of the super absorbent resin is very less and thus the produced product is low in production cost, the application effect is good and the preparation method is worthy of being widely promoted.

Description

technical field [0001] The invention relates to the field of microbial preparations, in particular to a method for preparing solid-state 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 orga...
