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

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.
