Thirty-six strains of ovicidal fungi were isolated from 122 investigated soil samples collected in Cuba. The isolated strains belong to 8 genera, 2 strains consist of sterile mycelium only. Most of the strains belong to the genus Fusarium (4 species, 1 undetermined strain), the remaining ones to Mortierella (3 species and 6 undetermined strains), Humicola(More)
Various species of the generaAlternaria, Stemphylium andCladosporium were shown to display a specific reaction characteristic for the given genus. In theAlternaria genus this is a 1-2-dehydrogenation of the A ring of the steroid molecule, inStemphylium 14α-hydroxylation and inCladosporium 7β-hydroxylation. This chemotaxonomic feature may supplement(More)
The amylolytic activity and especially the production of α-amylase (EC 3.2.1.1) and α-glucosidase (EC 3.2.1.20) was screened in imperfect fungi, mucoral fungi and some ascomycetes. The character of the polysaccharide system, which is responsible for the utilization of α (1 → 4) glucan, was specified with a conoominant screening of growth on soluble starch.(More)

Over the years 1983 to 1984, eight strains of Penicillium oxalicum were isolated from feed mixtures for chickens; all of them produced on wheat secalonic acid D (1 to 22 mg X kg-1). As found out, toxic dose of secalonic acid D for two-day, three--day and four-day chicken embryos is 0.90, 2.80 and 3.80 micrograms, respectively. Teratogenic effects,(More)
Species of the genus Scopulariopsis Bainier are currently found as contaminants in the air, in stored grain, pharmaceutical and food products; in addition, the species Scopulariopsis brevicaulis and Scopulariopsis candida act as human parasites causing some fingernail diseases, especially onychomycoses. Several strains of the genus were subjected to(More)

Individual species of the genus Paecilomyces are currently found as contaminants in foodstuffs of both animal and plant origin, in pharmaceutical, cosmetic, textile, leather, paper, and plastic products as well in those from both synthetic and natural rubber (Walters and Elphick, 1968; Blahnik and Zs 1963).
