最佳条件

The optimal determining conditions were obtained: adding quantity of a monolayer medium 15ml, the suspension concentration of Micrococcus luteus 109 cfu/ml, the adding quantity of Oxford Plate 100μl, agar concentration 1%, the concentration of Na2HPO4 1％, and the pH of the medium adjusted to 7.0. The medium was optimized by single factor and the orthogonal experiments on the basis of the centrifugate of distiller's grains. The optimal composition was obtained as follows: sucrose 0.6, peptone 0.1, yeast extract 0.2, K2HPO4?
