Abstract

The invention discloses a preparation method of a photosynthetic bacterial liquid and belongs to the technical field of bacterial liquid preparation. In order to solve the problems that the cost for preparation of photosynthetic bacteria is high and the activity of the prepared photosynthetic bacteria is low in the prior art, the provided preparation method of the photosynthetic bacterial liquid comprises the steps of preparing a photosynthetic bacterial basic culture solution; preparing a soybean meal paste, inoculating photosynthetic bacteria to the prepared basic culture solution, adding the soybean meal paste, culturing the basic culture solution under an illumination condition, supplementing the soybean meal paste after the basic culture solution of the photosynthetic bacteria is darkred, and completing the whole culture process when the photosynthetic bacteria become thick. According to the method, few raw materials are needed for preparing the photosynthetic bacteria, so that the high cost for using a yeast paste and the cumbersome process of using different compounds for preparing the culture medium are avoided. Soybean meal is adopted as a raw material and contains high content of proteins, nutrients can be provided for culture of the photosynthetic bacteria, and the cost is low. The obtained photosynthetic bacterial liquid is ultrahigh in viable bacteria number and stays in a blood-like thick state.

Description

technical field [0001] The invention belongs to the technical field of bacterial liquid preparation, and more specifically relates to a method for preparing photosynthetic bacterial liquid. Background technique [0002] Photosynthetic bacteria of the genus Pseudomonas in the family Rhodospirillaceae, such as Rhodopseudomonas palustris, Rhodopseudomonas capsulata, and Rhodopseudomonas globosa, are beneficial microorganisms often used in aquatic products, environmental protection and feed , studies have shown that the growth and metabolism of photosynthetic bacteria can produce rich B vitamins, carotenoids, coenzyme Q10, folic acid, etc. Therefore, it has very high nutritional value as an animal feed additive. In addition, photosynthetic bacteria can effectively remove organic matter, nitrogen, phosphorus, and sulfide in wastewater, and are often used in the field of aquaculture to reduce ammonia nitrogen, nitrite, and organic matter in ponds. There are also many kinds of med...
