Fig. 4From: Lipase production by Serratia marcescens strain SN5gR isolated from the scat of lion-tailed macaque (Macaca silenus) in Silent Valley National Park, a biodiversity hotspot in IndiaEffect of a various nitrogen sources and b different concentrations of meat extract on lipase production by Serratia marcescens strain SN5gR. Lipolytic activity is expressed in U ml−1. Each point represents the mean of values obtained from three separate experiments (n = 3). No triglycerides were added in the basal mediaBack to article page
