Production of extracellular enzymes in the entomopathogenic fungus Verticillium lecanii
This study investigates the mechanisms as well as strategies for purification and characterization of potential enzymes involved in pathogenesis of entomopathogenic fungi. The test strain of Verticillium lecanii that was screened, during the present investigation, proved to be an efficient producer of protein and polysaccharide degrading enzymes (amylase, protease, and lipase), hence indicating...
متن کاملeffect of some plant extracts and pesticides on entomopathogenic fungus, beauveria bassiana under laboratory conditions
the entomopathogenic fungus, beauveria bassiana (bals.) vuill., is one of the facultative insect pathogens with a significant host range and host specificity. conidial survival may be affected by either environmental factors or by bio-pesticides and chemical products used to protect crop plants. in this research, compatibility of the above mentioned fungus was studied with some traditional inse...
متن کاملIsolation and characterization of a chitinase gene from entomopathogenic fungus Verticillium lecanii
Entomopathogenic fungus Verticillium lecanii is a promising whitefly and aphid control agent. Chitinases secreted by this insect pathogen have considerable importance in the biological control of some insect pests. An endochitinase gene Vlchit1 from the fungus was cloned and overexpressed in Escherichia coli. The Vlchit1 gene not only contains an open reading frame (ORF) which encodes a protein...
متن کاملIsolation, partial characterization, and cloning of an extracellular chitinase from the entomopathogenic fungus Verticillium lecanii.
The entomopathogenic fungus Verticillium lecanii is a well-known biocontrol agent of fungal phytopathogens, as well as insect pests. A 42-kDa chitinase belonging to family 18 of the glycosyl hydrolases was isolated and partially characterized. Chitinase was purified using successive column chromatography on phenyl-sepharose, DEAE-sepharose, and CM-sepharose. The enzyme showed the highest activi...
متن کاملMass Production and Economics of Entomopathogenic Fungus, Beauveria bassiana, Metarhizium anisopliae and Verticillium lecanii on agricultural and industrial waste
Beauveria bassiana (Balsamo) Vuellemin, Metarhizium anisopliae (Metschnikoff) Sorokin and Vertillium lecanii are entomopathogenic fungi (EPF) that occur naturally in the environment and have a potential as biological control agents against many insect pests. A laboratory study was conducted to mass produce entomopathogenic fungus, Beauveria bassiana, Metarhizium anisopliae and Verticillium leca...
