Mycotoxin production by indoor molds.
Fungal growth in buildings starts at a water activity (a(w)) near 0.8, but significant quantities of mycotoxins are not produced unless a(w) reaches 0.95. Stachybotrys generates particularly high quantities of many chemically distinct metabolites in water-damaged buildings. These metabolites are carried by spores, and can be detected in air samples at high spore concentrations. Very little atte...
متن کامل[Mycotoxin producing fungi].
Mycotoxins are relatively small molecules characterized by a diversity of chemical structure and a diversity of biological activity. They are often genotypically specific for a group of species, but the same compound can also be formed by fungi belonging to different genera. Most of the mycotoxins known have been recognized as metabolic products of Aspergillus, Penicillium and Fusarium species....
متن کاملIsolation and screening of phytotoxin-producing actinomycetes for biological control of Cardaria draba
Cardaria draba is an important, troublesome weed in the sustainable production of wheat. Inthe first step of this study, 100 actinomycete isolates were purified from soil samples collectedfrom the rhizosphere and phyllosphere of plants in different provinces of Iran. All isolates weresubjected to primary screening by assaying the fermentation broth of the sterile surfaces of C.draba leaves. Con...
متن کاملTemporal Variation of Mycotoxin Producing Fungi in Norwegian Cereals
Spring barley is grown on about half of the Norwegian cereal area. The rest of the area is equally divided between wheat and oats. Most years the domestic production provides 70%-80% of the domestic market for bread wheat. Barley and oats are mainly grown for animal feed. During the years 2008-2012, severe epidemics of Fusarium head blight have led to increased mycotoxin contamination of cereal...
متن کاملMycotoxin-producing strains of Penicillium viridicatum: classification into subgroups.
Fifty-two isolates of Penicillium viridicatum Westling were divided into three groups based on ability to produce ochratoxin and/or citrinin, color, growth rate, type of growth, odor, and isolation source. Members of group I resemble one of the representative strains of P. viridicatum described in the literature; those belonging to group II differ from group I strains in several characteristics...
