摘要
Abstract
The experiments with one factor and orthogonal design were conducted to optimize medium of antagonistic bacteria A3 strain against TMV (Pseudomonas putida) with mass growth (OD600 value) as the index. A systematic study of carbon sources, nitrogen sources and inorganic chemicals was carried out. Carbon source“wheat bran”, nitrogen source“yeast extract powder”and inorganic chemical“CaCl2, CoCl2, MgSO4, FeSO4, KH2PO4”, were beneficial to the growth of A3. The results of L18(37) orthogonal tests showed that optimal medium menu included 15g wheat bran,15g yeast extract powder, 2.5g CaCl2, 0.5g CoCl2, 0.8g MgSO4, 0.5g FeSO4, 0.8g KH2PO4 and 1000mL distilled water, pH 7.0. The number of live bacteria could be 3.234×1012 cfu/mL in the optimized medium and the number increased by one orders of magnitude than original NB medium.关键词
