title: [Effect of various nitrogen sources on lipase formation by Rhizopus microsporus].
abstract: The effect of organic and mineral nitrogen sources on the production of lipolytic enzymes and the accumulation of biomass was studied with Rhizopus microsporus UzLT-I. Addition of mineral nitrogen sources to the growth medium weakly stimulated synthesis of lipase by the fungus. The production of lipolytic enzymes was highest on media with organic nitrogen compounds, particularly yeast autolysate and fodder yeast cells (0.1: 0.25%). The lipolytic activity of the cultural broth on media with these nitrogen sources increased by 50% cf. the control.
