High levels of amylolytic and lipolytic activities were recorded. Proteolytic, cellulolytic andurease activities were low. Using thin layer chromatography techniques, ochratoxin A was detected in extracts of P. variabile, rubratoxin B in P. purpurogenum and citrinin in P. steckii [P. citrinum]. Toxicity levels against brine shrimp larvae and 12 microorganisms (10 bacteria and 2 yeasts) indicated great variability amongst the extracts. The use of these characters in the taxonomy of P. is mentioned.Collection: Reprints Collection
