| 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). | ||
