Abstract:
A suitable medium,95% wheat bran +5% maize flour + 5% soybean powder,was chosen for mass production of Beauveria bassiana for solid-state fermentation,and the spore count of primary product was up to 244.7?10~(8) conidia per gram.The optimal conditions for solid-state fermentation in a 25m~(3) solid fermentator were as followings.Initial water content of the medium was 60%~65%.The best aeration ratio was: 0 in first 12h,1:2 in 12~48h and 1∶1 after 48h.In order to emit heat released by substantial growth of mycelium,it was necessary to control the temperature from 12h to 48?8h.As to the desiccating process,the optimal condition was with dried air at normal temperature to keep conidia viable.
