Effects of Carbon Concentration and Ratio of Carbon to Nitrogen on the Growth and Sporulation of Beauveria bassiana
摘要
Abstract
For the purpose of exploring the scale production path of Beauveria bassiana ,taking solid basal medi-um composed of glucose ,peptone and salts ,the effects of carbon concentration and ratio of carbon to nitrogen on the growth and sporulation of five strains of Beauveria bassiana were studied .The results showed that ex-cept for the B72 ,all the B .bassinana strains attained the best growth at a C/N of 10∶1 ,when the carbon con-centration was 24 g・L-1 for B76 ,16 g・L-1 for B70 ,B246 and B252 .The optimal conditions for B72 growth were 24 g・L-1 carbon concentration with a C/N of 20∶1 .The highest spore yields conditions for B72 and B76 were 24 g・L-1 carbon concentration with a C/N of 20∶1 .The optimal conditions for sporulation were 24 g・L-1 carbon concentration with a C/N of 40∶1 for B70 ,8 g・L-1 carbon concentration with a C/N of 10∶1 for B246 and 16 g・L-1 carbon concentration with a C/N of 60∶1 for B252 ,respectively .The results indicated that the C/N had more influence on B .bassinana growth and sporulation than the carbon concentration ,low C/N was condu-cive to most B .bassinana growth and sporulation .关键词
