ochratoxin a production in bavarian cereal grains stored at 15 and 19% moisture content.wheat, barley, and maize, each in 15-kg parcels at 15 and 19% initial moisture content (imc), were kept in a bavarian farm granary from june through november 1990. during this period, the grain at each imc was analyzed for mycotoxins and monitored for grain temperature, carbon dioxide, seed germination, and microfloral incidence and abundance. barley and maize stored for 20 weeks at 19% imc contained ochratoxin a in amounts of 70 and 90 microg/kg, respectively. this mycotoxin was not detected in ...19921514845
the sequence of the isoepoxydon dehydrogenase gene of the patulin biosynthetic pathway in penicillium species.interest in species of the genus penicillium is related to their ability to produce the mycotoxin patulin and to cause spoilage of fruit products worldwide. the sequence of the isoepoxydon dehydrogenase (idh) gene, a gene in the patulin biosynthetic pathway, was determined for 28 strains representing 12 different penicillium species known to produce the mycotoxin patulin. isolates of penicillium carneum, penicillium clavigerum, penicillium concentricum, penicillium coprobium, penicillium dipodom ...200717043910
richness of endophytic fungi isolated from opuntia ficus-indica mill. (cactaceae) and preliminary screening for enzyme production.opuntia ficus-indica mill. (forage cactus) is farmed with relative success in the semi-arid region of the brazilian northeast for commercial purposes, particularly as forage and food. endophytic microorganisms are those that can be isolated inside plant tissues and can be a new source to production of enzymes with different potentialities. the objective of this study was to describe the richness of endophytic fungi from o. ficus-indica and to detect the capacity of these species to produce extra ...201222806020
dark stains on rock surfaces in driny cave (little carpathian mountains, slovakia).mycobiota are important in underground ecology. in 2014, we discovered dark stains on clayey sediments on the walls of driny cave, slovakia. our description is based on the morphology of the fungus and the phylogenetic relationships of the internal transcribed spacer (its) region. in addition, data on its capacity for the production of extracellular enzymes, growth, and survival in vitro at different temperatures are reported. our analyses revealed that this dark stains on the wall was produced ...201627315167
