Tributyrin specifically induces a lipase with a preference for the sn-2 position of triglyceride in Geotrichum sp FO401B

The extracellular Lipases A and C produced by Geotrichum sp. FO401B have a preference for the sn-1,3 and sn-2 positions of triglyceride, respectively. Total production of these lipases was increased by plant oils and tributyrin. Butyl Toyopearl column chromatography demonstrated that only Lipase C was produced in the presence of tributyrin. Lipase C hydrolysed natural fats except sardine oil preferentially at the sn-2 position, but it showed little stereoselectivity for triolein.
