Cuticle-degrading proteases produced by the entomopathogenic fungus Beauveria bassiana in the presence of coffee berry borer cuticle
A Brazilian isolate of Beauveria bassiana (CG425) that shows high virulence against the coffee berry borer (CBB) was examined for the production of subtilisin-like (Pr1) and trypsin-like (Pr2) cuticle-degrading proteases. Fungal growth was either in nitrate-medium or in CBB cuticle-containing medium under both buffered and unbuffered conditions. In unbuffered medium supplemented with cuticle, t...
متن کاملAllergens of the entomopathogenic fungus Beauveria bassiana
BACKGROUND: Beauveria bassiana is an important entomopathogenic fungus currently under development as a bio-control agent for a variety of insect pests. Although reported to be non-toxic to vertebrates, the potential allergenicity of Beauveria species has not been widely studied. METHODS: IgE-reactivity studies were performed using sera from patients displaying mould hypersensitivity by immunob...
متن کاملSpecific induction of a cuticle-degrading protease of the insect pathogenic fungus Metarhiziurn anisopliae
The insect pathogenic fungus Metarhizium anisopliae produces several extracellular cuticle-degrading proteases and evidence is consistent that one of these, a chymoelastase PRl, is a determinant of pathogenicity. We have shown previously that the wide-domain regulatory circuits of carbon and nitrogen derepression regulate PRI production. In the present work we have established in addition that ...
متن کاملN-Acetyl-d-Glucosamine-Mediated Regulation of Extracellular Protease in the Entomopathogenic Fungus Beauveria bassiana.
The entomopathogenic fungus Beauveria bassiana GK2016 grown in a liquid medium incorporating gelatin as the sole carbon and nitrogen source produced an extracellular serine protease (molecular weight, 35,000; pI ca. 10). Without gelatin, B. bassiana could utilize N-acetyl-d-glucosamine (GlcNAc; 2-acetamido-2-deoxy-d-glucose) as the sole source of carbon and nitrogen, and GlcNAc availability inc...
متن کاملPurification and Properties of an Extracellular Protease Produced by the Entomopathogenic Fungus Beauveria bassiana.
Beauveria bassiana GK2016 grown in a medium with gelatin as the sole carbon and nitrogen source produced an extracellular protease. The protease production was highest when the fungus was grown on a semiliquid medium and was purified about 18-fold, with a recovery of 21%. The protease molecular weight was estimated by sodium dodecyl sulfate-polyacrylamide gel electrophoresis to be about 35,000....
