FERMENTATION STUDIES OF IOACTIVE FUNGAL STRAIN ASS SP. SS ISOLATED FROM ASSMA ROX
Abstract
- Endophytic fungal strain Aspergillus sp. SS 7 isolated from the rhizome of ingiber cassumunar Roxb. was used for the investigation of optimal fermentation conditions such as various carbon and nitrogen sources, different culture media, age of inoculum, size of inloculum and pH utilization. In utilization of carbon sources, starch and glycerol were the best whereas yeast extract and soybean were the best nitrogen sources. In antimicrobial activity of various carbon sources, glucose medium showed very high activity against Candida albicans whereas various nitrogen sources, oat meal medium indicated very high activity against Malasseia furfur. The investigation of the morphological characters on different media, medium 1, 3, 7, 9 and 10 were good media. As a result of antimicrobial activity on different media, medium 7 and medium 9 were the best for fermentation medium. In the study of inoculum optimization, two days old (age of inoculum) and 1.5% of seed culture at fifth day fermentation were suitable for the production of bioactive metabolites. In the study of pH utilization, pH 6 was the best for extraction of the bioactive compounds.
