Lipase production by strains of Aspergillus species isolated from contaminated body creams

Aspergillus species isolated from contaminated body creams were screened for their ability to produce extracellular lipase. Of the 6 strains tested two, identified as Aspergillus niger AC-5 and AC-7 and one strain ofAspergillus fumigatus. AF-3 were capable of producing extracellular lipase in appreciable amounts. A. nigerAC-5 was the highest lipase producer, followed by A. fumigatus AF-3,...
