Rv. Muralidhar et al., A response surface approach for the comparison of lipase production by Candida cylindracea using two different carbon sources, BIOCH ENG J, 9(1), 2001, pp. 17-23
A response surface approach has been used to study the production of extrac
ellular lipase by Candida cylindracea. Medium constituents were optimised f
or the production of lipase by central composite design. A 2(5) design matr
ix was used in the experiments with only the carbon source being varied. Th
e optimal yield of lipase was 17.30 U/ml using glucose as the carbon source
and 47.25 U/ml using olive oil as the carbon source. All the other medium
constituents namely yeast extract, malt extract, peptone and tween 80 were
simultaneously optimised. Experiments conducted at the predicted optimum le
vels fitted with the predicted optima. Based on these experimental conditio
ns, medium containing olive oil appears to a better medium for fermentative
production of C. cylindracea lipase. (C) 2001 Elsevier Science B.V. All ri
