Fungi are the predominant source of tannase for industrial production though other microorganisms are being exploited for industrial production and applications. In this study the ability ofA. versicolor,F. equisetiandP. citrinumto secrete tannase using pineapple peel and acacia fruits was assessed. The pineapple peel and acacia fruits were used as source of tannins for tannase and gallic acid production under submerged fermentation. The tannin concentration in pineapple peel was higher than acacia. After fermentation, acacia was better utilised by the three fungal strains producing the least tannin concentration, higher biomass weight, gallic acid concentration, protein concentration and tannase activity. However,A. versicolorbest utilized the two substrate compared toF. equisetiandP. citrinum. In conclusion pineapple peel and acacia nuts are good substrate for tannase and gallic acid production using the fungi strainsA. versicolor,F. equisetiandP. citrinum. |
