Parametric optimisation of Aspergillus terreus lipase production and its potential in ester synthesis

Parametric optimisation of lipase from Aspergillus terreus yielded 7780 U/l in a medium containing corn oil (2% v/v) and casein (0.1% w/v). Maximum production was observed at pH 9.0 and at 37°C in 96 h. Secretion of lipase was increased by Ca<SUP>2+</SUP> and Mg<SUP>2+</SUP> ions. The enzyme has good potential for synthesis of fatty acid esters of sugars, sugar alcohols, aliphatic alcohols and ascorbic acid which are industrially important
