Abstract

Seven carbon sources; Glucose,Sucrose,Soluble starch,Pectine,Dibis,Wheat seeds
extract and Rice grains extract extract individually incorporated in different liquid
media were evaluated for their effects on sporulation,percent of spores germination
and fungal biomass dry weight of entomopathogenic fungus Beauveria bassiana for
four incubation periods ;1,2,3 and 4days at 28±1c. Carbon used in the basal medium
as 8g/l.The results showed that glucose,rice grains extract,wheat seeds extract were
significantely superior(p<0.05) to induce the fungal sporulation which recorded
67,69,68×10 5spore/ml after 4 days of incubation, respectively.Soluble starch was more efficiency for spores germination,whereas the percent of spores germination
was 24.3 after 4 days of incubation. Rice grains extract increased significantly the
dry weight of fungus which recorded 0.507g/ml after 4days of
incubation.Pectine,soluble starch,sodium nitrate,methionin and glycin were less
efficiency for biomass production(0.2g/50ml).
