Lipase production by Penicillium restrictum using solid waste of industrial babassu oil production as substrate

Lipase, protease, and amylase production by Penicillium restrictum in solid -state fermentation was investigated. The basal medium was an industrial wa ste of babassu oil (Orbignya oleifera) production. It was enriched with pep tone, olive oil, and Tween-80. The supplementation positively influenced bo th enzyme production and fungal growth. Media enriched with Tween-80 provid ed the highest protease activity (8.6 U/g), whereas those enriched with pep tone and olive oil led to the highest lipase (27.8 U/g) and amylase (31.8 U /g) activities, respectively.
