Lipases (triacylglycerol hydrolases) are hydrolytic enzymes that can catalyze the hydrolysis of the ester bond of long-chain acylglycerols at the oil-water interface. The present study investigated the effects of inducers, surface-active materials, activators, and inhibitors in the fermentation medium on lipase activity in Rhizopus delemar. In the presence of certain commercial oils and tributyrin as an inducer, lipase activity decreased in the order of sunflower oil > soybean oil > hazelnut oil > corn oil > tributyrin > olive oil. In addition, the effects of the stirring and aeration rates on lipase activity were investigated. To investigate the effect of surface-active materials on lipase activity …
