荚膜红假单胞菌应用型扩大培养液的优化试验

Optimizing test of a scale-up medium of Rhodopseudomona capsulata

采用正交设计试验 ,探讨基础营养培养液中醋酸钠、酵母膏、蛋白胨等 5种成分对荚膜红假单胞菌 (Rhodopseudomonacapsulata)生长繁殖的影响 ,优化应用型扩大培养液配方。结果表明 ,醋酸钠和酵母膏对荚膜红假单胞菌生长繁殖具有显著的影响。荚膜红假单胞菌应用型扩大培养液可为 :在 1L的养殖水体中添加 6g醋酸钠和 0 1

Influence of five compositions in the basic nutritional medium, e.g. acetate, yeast extract, peptone, etc. on the growth and reproduction of \%Rhodopseudomona capsulata\%, and the optimization of ingredients of a scale-up medium were studied using orthogonal design. The results showed that acetate and yeast extract had remarkable effect on the growth and reproduction of \%R. capsulata\%. Sxi g acetate and 0.1 g yeast extract was added to the applied scale-up medium of \%R. capsulata\% in 1 L breeding water.
