[Effect of metal ions on the lipolytic activity of Rhizopus microsporus].

Various metal ions have different effect on the lipolytic activity of Rhizopus microsporus in the course of cultivation on nutrient media having diverse composition. The fungus particulary requires metal ions for the production of lipase on a mineral medium. Additional introduction of microelements into a medium containing maize extract has no significant effect on the lipolytic activity. Active biosynthesis of lipase by the culture requires zinc.
