Method for preparing rhodopseudomonas palustris for feed by utilizing white maize meal as raw material

Abstract

The invention discloses a method for preparing rhodopseudomonas palustris for feed by utilizing white maize meal as a raw material. The preparation of rhodopseudomonas palustris for feed can be effectively solved, so that the requirement of the feed breeding industry for feed production is met. According to the technical scheme, the method comprises the following steps: preparing a strain, culturing the strain, preparing a liquid fermentation culture medium, inoculating, performing fermentation cultivation, performing carrier adsorption and drying. The method disclosed by the invention has the advantages that 1, the raw materials of the fermentation medium mainly are white maize meal and other materials which are rich in resources, low in price and simple and readily available; 2, the fermentation medium is simple in formula, fermentation production in an automatic liquid fermentation tank is realized, the operation is convenient, the culture is convenient, the growth speed is high, and the fermentation period is greatly shortened and is only 72-96 hours; 3, the rhodopseudomonas palustris for feed can be prepared; 4, the rhodopseudomonas palustris for feed is good in application effect and outstanding in economic and social benefits; and 5, the microbial strain rhodopseudomonas palustris AS1.2352 permitted in the Department of Agriculture in China is used for fermentation production, the safety is high, and the rhodopseudomonas palustris is a green additive for feed.

Description

technical field [0001] The invention relates to the technical field of biological fermentation, in particular to a method for preparing rhodopseudomonas palustris for feed by using white cornmeal as a raw material. Background technique [0002] According to Dong Xiuzhu's (2001) "Common Bacteria System Identification Manual" classification, Rhodopseudomonas palustris belongs to purple non-sulfur bacteria, Rhodopseudomonas genus, in the natural carbon, nitrogen, sulfur conversion cycle It plays an important role and is one of the main participants in the material cycle and energy flow in the environment. It has the ability to enrich a variety of trace elements. The bacteria are rich in nutrients, high in protein content, and rich in various biologically active substances, and the active strains Contains certain disease-resistant and stress-resistant substances, and has strong adaptability, can tolerate high-concentration organic wastewater and strong decomposition and transfor...

Problems solved by technology

Domestic production of Rhodopseudomonas palustris generally uses plastic barrels, etc., using the characteristics of Rhodopseudomonas paluscans to grow under light anaerobic conditions. The production cycle is long, generally more than 7 days. The combination of ingredients in the base formula is relatively complicated, and generally requires several or more than a dozen nutrients such as carbon sources, nitrogen sources, phosphorus sources, trace elements, vitamins, etc. to adjust the pH, and the actual preparation process is cumbersome. To meet the needs of the feed farming industry for feed production, its innovation is imperative
