| Abstract: | 155 Fungal isolates, isolated from marine
water, belong to five fungal species viz Aspergillus
niger,
A. fumigatus, Penicillium expansum, Trichoderma virens and Penicillium spp were screened for alpha
amylase production. All the isolates belong to A.niger, 12 isolates of Trichoderma
virens and A.fumigatus, 10
isolates of Penicillium expansum and
2 isolates of Penicillium spp , were
produced alpha amylase. A.niger strain SK01 was selected for alpha amylase production. Vegetables
wastes were used as a substrate by solid state fermentation under 0,10,20,40
and 50% moisture content. Enzyme activity was studied at 30°C, 40°C, 50°C, 60°C, 70°C temperature and the pH 5,6,7,8 and 9. Wastes supported growth and
enzyme activity at all parameters tested. Maximum activity was recorded at 0%
moisture content, 70°C
temperature and pH 9. |
