The screening of entomopathogenic fungi, 7 isolates of Metarhizium spp., 12 isolates of Beauveria spp., and 1 isolate of Hirsutella citriformis against fruit fly was performed in Lampang Agricultural Research and Training Centre, Lampang, Thailand. The efficacy test was done by spraying suspension of 10 spores per ml of fungus on Bactrocera dorsalis in completely randomized design experiments. ...

Microbial biotransformations constitute an important alternative as models for drug metabolism study in mammalians and have been used for the industrial synthesis of chemicals with pharmaceutical purposes. Several microorganisms with unique biotransformation ability have been found by intensive screening and put in commercial applications. Ten isolates of Beauveria sp genus filamentous fungi, i...

The course of transformations of testosterone and its derivatives, including compounds with an additional C1,C2 double bond and/or a 17alpha-methyl group, a 17beta-acetyl group or without a 19-methyl group, by a Beauveria bassiana culture was investigated. The fungi promoted hydroxylation of these compounds at position 11alpha, oxidation of the 17beta-hydroxyl group, reduction of the C1,C2 or C...

We describe a case of fungal keratitis due to Beauveria bassiana in a farmer with Fuchs' dystrophy, treated with amphotericin B. Surgery with penetrating keratoplasty was necessary to resolve the lesions. Susceptibility testing and molecular sequencing permitted the identification and treatment of this rare aetiological agent of invasive fungal disease.

New beauvericins have been synthesized using the nonribosomal peptide synthetase BbBEAS from the entomopathogenic fungus Beauveria bassiana. Chemical diversity was generated by in vitro chemoenzymatic and in vivo whole cell biocatalytic syntheses using either a B. bassiana mutant or an E. coli strain expressing the bbBeas gene.

A new hydroxylated derivative was efficiently prepared by transforming the natural anti-cancer product, piperlongumine, with Beauveria bassiana ATCC 7159. Its structure was determined to be 5-hydroxylpiperlongumine on the basis of the spectroscopic data. The absolute configuration at C-5 was established as R by Mosher's method.

Background. The New Zealand forest industry would greatly benefit from a successful way of controlling insect pests. The entomopathogenic fungus, Beauveria bassiana could hold such potential and has previously been shown to be capable of endophytic colonisation of the Monterey pine Pinus radiata. Nevertheless clarifications on its mode of transmission, persistence and action in this plant are r...
