Abstract: The present study was conducted in the Laboratory of
Biotechnology and Mycology, Department of Botany, GC University,
Faisalabad with the objective to study the production of extracellular
lipases by Penicillium chrysogenum through solid- state
fermentation (SSF). Penicillium chrysogenum was screened for the
extracellular lipase production. The maximum extracellular lipase
activity was obtained at 28oC after 72 h by using 1 mL
inoculum level. 15g of mixed substrates (Almond+ Soybean+ Sunflower) was
optimized for maximum extracellular lipase production. Agricultural by
products, nitrogen sources and carbon sources were also optimized for
the maximum production of enzyme. Maximum production of the
extracellular lipase (64.77±0.155a U/mL) was obtained when
olive oil was used as additional oil. Tween 80 and yeast extract were
optimized as the best additional carbon and nitrogen sources
respectively.
