SCREENING OF OPTIMAL NUTRITION CONDITIONS OF THE STRAIN PRODUCING INSECTICIDE NO. 48 IN LIQUID CULTURE
杀虫素48号产生菌株最适液体营养条件的筛选

By using method of design and result analy sis of the orthogonal experiment,optimal nutrition conditions for the strain pro ducing insecticide No.48 in liquid cult were scroened,which were composed of (%):Starch soluble 3,Glucose 2,Peanut cake powder 4,Protose p eptone 0 6,(NH4) 2SO 4,0 3 and K 2HPO 4,0.10.Furthermore,the experiment of compari son between optimal and initial put n.showed that this strain biomass increase d by 59 percent (P<0 01).
