The production of lipases by some <i>Candida</i> and <i>Yarrowia</i> yeasts

Abstract

Abstract The activities of the free and the cell‐bound lipases of Candida rugosa, Candida guilliermondii, Candida curvata, Candida deformans and Yarrowia lipolytica that had been grown on a complex medium with various carbon and nitrogen sources were examined. The highest activities were observed with citrate and succinate as the carbon sources. In some cases olive oil was used as the efficient inducer of the cell‐bound lipases. The cells grown in the presence of the organic nitrogen sources (peptone, urea, soy flour) exhibited higher lipase levels than those cultivated in the medium containing ammonium as the nitrogen source. The extracellular enzyme was detected only in cultures grown with urea, peptone or soy flour as the nitrogen source.
