SCREENING OF POTENTIAL BIOTECHNOLOGICAL APPLICATIONS FROM OBLIGATE HALOPHILIC FUNGI, ISOLATED FROM A MAN-MADE SOLAR SALTERN LOCATED IN PHETCHABURI PROVINCE, THAILAND

摘要

This is the continuation study of obligate halophilic fungi isolated from a man-made solar saltern located inPhetchaburi province, Thailand. The isolation site was hypersaline extreme habitat. Six halophilic fungi which werescreened for applications belonged to 4 species and 5 strains of Aspergillus genus namely A. flavus, A. gracilis, A.penicillioides (2 strains) and A. restrictus. A yeast namely, Sterigmatomyces halophilus was also one of the isolate screenedfor biotechnological potentials. Antibacterial, antioxidant and enzymatic activity were determined for each of the strains. Allof the isolates in this study were found to have at least one of the applications screened. A. flavus, A. gracilis and A.penicillioides (1) were found to have high antibacterial potential. A. flavus and A. penicillioides (2) showed the mostantioxidant activity while A. gracilis and A. restrictus were found to be most promising candidates for enzymes (of the fiveenzymes tested) having activity under saline conditions.
