Chemically managed plants impose environmental risks to humans and environment. Using biological approaches control plant diseases is a more effective environment friendly alternative. The approach disease refers controlling by using organisms like fungi, bacteria viruses. This can be done introduction or utilization of resident antagonistic living organisms. Biological achieved through differe...

Paecilomyces lilacinus (Thom) Samson LPS 876, a locally isolated fungal strain, was grown on minimal mineral medium containing "hair waste," a residue from the hair-saving unhairing process, and produced a protease with keratinolytic activity. This enzyme was biochemically characterized. The optimum reaction conditions, determined with a response surface methodology, were 60°C and pH 6.0. It wa...

During 1997- 99 one seed samples of each 17 sesame cultivars (totally 17 samples) were collected from 10 localities in Iran. Blotter method and culture media (PDA, PMA, WA, CA, SNA, CLA, CYA, KCLA, WALM, MEA) were used to isolate and identity the mycoflora present on different parts of seeds. Totally, 145 isolates were obtained which included 34 species of 15 genera. The identified fungi were: ...

A fungus producing all a-glucosidase that synthesizes a-1,3and a-1,2-linked glucooligosaccharides by transglucosylation was isolated and identified as Paecilomyces tilacinus. The cell-bound enzyme responsible for the synthesis was extracted by suspension of mycelia with O.1M phosphate buffer (pH 8.0), and the extract was purified. The molecular weight and the isoelectric point were estimated to...
