The production and uses of Beauveria bassiana as a microbial insecticide
World Journal of Microbiology and Biotechnology, 2016Among invertebrate fungal pathogens, Beauveria bassiana has assumed a key role in management of numerous arthropod agricultural, veterinary and forestry pests. Beauveria is typically deployed in one or more inundative applications of large numbers of aerial conidia in dry or liquid formulations, in a chemical paradigm.

BIOSYNTHESIS OF OOSPOREIN IN BEAUVERIA BASSIANA (BALS.) VUILL
Canadian Journal of Biochemistry, 1966Substrates labeled with carbon-14 were used to investigate the biosynthesis of oosporein in cultures of Beauveria bassiana. Acetate-1-14C and acetate-2-14C were good precursors. Degradation of the pigment by oxidation with chromic acid gave acetic acid which was labeled in the carboxyl and methyl carbon atoms, respectively, with little randomization ...

Metabolism of parthenin by Beauveria bassiana ATCC 7159
Die Pharmazie, 2007Two new metabolites were isolated from the biotransformation reaction of parthenin by Beauveria bassiana ATCC 7159 along with the known naturally occurring sesquiterpene lactones hymenolin and dihydrocoronopilin. The new metabolites: are 3β,4β,6β-trihydroxy-10αH,11α-methyl-ambrosa-1-en-12-oic acid-γ-lactone and 3α,6β-dihydroxy-4β-hydroperoxy-10αH, 11α ...

Microbial metabolism of 1-aminoanthracene by Beauveria bassiana
Bioorganic & Medicinal Chemistry, 2008The carcinogen and mutagen, 1-aminoanthracene, was efficiently metabolized by the fungal strain Beauveria bassiana ATCC 7159 to yield three new metabolites identified as 1-acetamido-5-[(4'-O-methyl-beta-d-glucopyranosyl)oxy]anthracene, 1-acetamido-8-[(4'-O-methyl-beta-d-glucopyranosyl)oxy]anthraquinone, and 1-acetamido-6-[(4'-O-methyl-beta-d ...

Characterization of Beauveria bassiana isolates from Kyrgyzstan
Journal of Invertebrate Pathology, 2019We report on the enzootic foci of the insect pathogenic fungus, Beauveria bassiana, found in high meadows in the middle mountain steppes of Kyrgyzstan, at elevations from 1000 m to 2200 m. The growth characteristics of various B. bassiana isolates on different media and as a function of temperature were studied.

The Capability of Beauveria Bassiana for Cellulase Enzyme Production
Proceedings of the 7th International Conference on Bioscience, Biochemistry and Bioinformatics, 2017The objective of this study is to investigate the ability of cellulase enzyme production from Beauveria bassiana comparing Trichoderma viride (positive control) in the cellulose-agar medium using carboxymethylcellulose (CMC). The formation of clear zone by chromogenic reaction around the margin of the fungal colony demonstrated in CMC agar using agar ...

Biotransformation of warfarin by the fungus Beauveria bassiana
Applied Microbiology and Biotechnology, 1992Biotransformation of racemic warfarin by the fungus Beauveria bassiana IMI 12939 was studied as part of an investigation into alternative methods for the production of drug metabolites. Resting cell suspensions in buffer were able to biotransform warfarin. High activity occurred within a broad pH range (6.0–9.0) with an optimum at 7.0.

Pesticide effects on germination of Beauveria bassiana
Transactions of the British Mycological Society, 1984Four fungicides and four insecticides significantly inhibited germination of B. bassiana compared with controls. The chemicals can be classed according to four levels of inhibition. Acylalanine and fenvalarate were least inhibitory, permethrin was slightly more inhibitory, azinphos-methyl and chlorothalonil were strongly inhibitory while metiram ...

The formation of protoplasts from Beauveria bassiana
Applied Microbiology and Biotechnology, 1987Beauveria bassiana protoplast formation from blastospores, conidia and mycelia was studied. The method of protoplast formation involves preincubation of the fungal cells with dithiothreitol and subsequent treatment with an enzyme mixture consisting of: cellulase, chitinase, β-glucuronidase and lysozyme. Using this procedure protoplasts were formed from
