Pigments of the genus Beauveria

Canadian Journal of Botany, 1968
Red coloring substances found in isolates of the imperfect fungus Beauveria were identified as the dibenzoquinone pigment oosporein. Yellow pigments were isolated from both B. bassiana and B. tenella cultures and found to be mixtures of similar compounds. Two types (designated tenellins and bassianins) occurred.

The Fungus Beauveria tenella

Science, 1962
Beauveria tenella, an insect pathogen, grows well and sporulates freely in submerged culture. Enzymes that loosened bovine hair that were found in broth cultures were not produced in the presence of chitin, and substitution of peptone broth for peptone-glucose broth did not increase their concentration. Under certain conditions,

Parasexuality in Beauveria bassiana

Journal of Invertebrate Pathology, 1991
Abstract The parasexual cycle of the Deuteromycete Beauveria bassiana is described. Diploids are presumably highly unstable and are not isolated, but haploid recombinants are directed recovered from the heterokaryon formed between auxotrophic strains.

Toxins of the entomophagous fungus Beauveria bassiana

Journal of Invertebrate Pathology, 1968
Abstract The toxic substances produced by submerged cultures of Beauveria bassiana in a medium containing glucose, starch, corn-steep liquor, CaCO3, and NaCl were examined. The high-molecular-weight compounds toxic for Galleria mellonella larvae were separated from the culture filtrate by means of precipitation by ammonium sulfate and desalting on ...

Medical Management of Beauveria bassiana Keratitis

Cornea, 2000
To describe a case of Beauveria bassiana keratitis and to discuss the management of this rare condition.An 82-year-old woman underwent surgical repair of a graft wound dehiscence. Seven months later, shortly after the removal of sutures, the patient developed a fungal keratitis. B. bassiana was identified as the infecting organism.

Pathogenicity of Beauveria bassiana in Mice

Journal of Veterinary Medicine, Series B, 1992
SummaryThe potential pathogenicity of Beauveria bassiana was examined by intramuscular injection of high (2 times 108) or low (2 times 105) concentrations of conidia spores, into the left or right quadriceps muscles of CD‐1 mice, respectively. The injection sites were monitored over a period of 28 days by both microbiological and histopathological ...

Mycotic Keratitis due to Beauveria alba

Cornea, 1984
A 70-year-old white man developed mycotic keratitis following phacoemulsification and intraocular lens implantation. Extensive therapeutic surgery was necessary to control the infection. Beauveria alba, a saprophytic fungus, was cultured and demonstrated in the corneal button by histopathologic examination.

Physiological characteristics and virulence of auxotrophic and morphological mutants of Beauveria Brongniartii (sacc.) petch (= Beauveria tenella)

Mycopathologia, 1985
Various mutants have been obtained of B. brongniartii, a hyphomycete pathogenic for insects. Both one pigment less and two blastospore negative mutants retained their initial virulence. Thus neither the characteristic parasitic blastospore morphology nor the synthesis of the pigment appeared to be required for pathogenesis.

The biocatalytic reactions of Beauveria spp.

Journal of Molecular Catalysis B: Enzymatic, 2000
Fungi of the Beauveria spp., typified by Beauveria bassiana ATCC 7159, are among the most frequently used whole cell biocatalysts. They have been reported to catalyse many different reactions, including oxidative, reductive and hydrolytic transformations, of a wide range of substrates.

Serological classification of Beauveria bassiana

Journal of Invertebrate Pathology, 1988
Abstract Antigenic properties of blastospores of Beauveria bassiana and Beauveria brongniartii were analyzed by the slide agglutination and reciprocal absorption tests and the existence of at least three serotypes (B 1 , B 2 , and B 3 ) in B. bassiana was demonstrated.
