Byssochlamys and related Paecilomyces strains are often heat resistant and may produce mycotoxins in contaminated pasteurised foodstuffs. A comparative study of all Byssochlamys species was carried out using a polyphasic approach to find characters that differentiate species and to establish accurate data on potential mycotoxin production by each species. Phylogenetic analysis of the ITS region...

Since early years, a need has always been felt for some control on the quality of foodstuffs. With the discovery of aflatoxins in the early sixties, health authorities in man countries have become active in establishing regulations to protect their citizens and livestock fro t potential harm caused by mycotoxins. FDA mycotox-ins-in-foods sampling program is continuing with an objective to remov...

The antibiotic patiilin (I) has been reported to inhibit seed germination becauise of its toxicity (7). We considered that this butenolide (I) might induce light sensitive dormancy in seeds of lettuce because of its structural similarity to coumarin (II) and ramulosin (III), (see fig 1), which have been demonstrated to possess this biological activity (2,5,6). Possible activitv was tested in th...

Patulin is a high-hazardous mycotoxin formed in apples affected by the fungus. This mycotoxin, when ingested, has irreversible effect of deteriorating health. Most often, patulin enters human body through processed apple products or baby food. The countries European Union have decided to reduce level maximum residue lowest that can be measured analytical instruments. Therefore, aim this work de...

Nucleotide sequences of the isoepoxydon dehydrogenase gene (idh) for eight strains of Byssochlamys nivea were determined by constructing GenomeWalker libraries. A striking finding was that all eight strains of B. nivea examined had identical nucleotide sequences, including those of the two introns present. The length of intron 2 was nearly three times the size of introns in strains of Penicilli...
