Effects of different fatty acids in lipase production by Candida rugosa

Abstract

Oleic acid has been reported as a good inducer of lipase production by Candida rugosa. In order to know if this enzyme is induced by oleic acid itself or by a metabolite, different short chain fatty acids were tested. Butyric acid was the best carbon source to growth microorganism but it did not induce lipase production. Although caprylic and capric acid were the best inducers of lipase production, at concentrations up 1 g/1 they have toxic effect in Candida rugosa growth. Thus, from the point of view of industrial production oleic acid could be considered as the best substrate tested.

Effect of environmental conditions on extracellular lipases production and fungal morphology from Aspergillus niger MYA 135

“…In this connection, among the various fatty acids reported to induce lipase secretion by Candida rugosa, oleic acid was the best substrate [12]. In addition, northern blotting hybridization experiments showed that during batch growth of C. rugosa in rich medium containing oleic acid, the lipase specific mRNA reached its highest level during the late exponential growth phase [13].…”

Effect of lipids and surfactants on extracellular lipase production by Yarrowia lipolytica

“…21 Oleic acid also induced lipase secretion by Candida rugosa. 22 Also, extracellular lipolytic activity from a particular strain of Y lipolytica 14 was enhanced by the presence of oils (ie olive oil).…”

Production of extracellular lipase by Candida cylindracea CBS 6330

“…A high concentration production of an extracellular lipase was achieved in the fed-batch culture of Pseudomonas¯uorescens with CO 2 dependent feeding of olive oil [12]. Other types of cultivation performance aimed at lipase production are described in literature [13,14,15] but the mostly used is the batch cultivation of free cells [1,3,16].…”
