Effect of a Teucrium polium L. extract on the growth and fatty acid composition of Saccharomyces cerevisiae and Yarrowia lipolytica

Abstract

Aqueous Teucrium polium extract slightly inhibits the growth of Saccharomyces cerevisiae (K^sub i^=0.029 [g/l]^sup -1^) and Yarrovia lipolytica (K^sub i^=0.061 [g/l]^sup -1^). However, this extract causes important changes in the unsaturation degree (Δ/mol) of the cellular lipids. It moreover favours the increase of the linolenic acid concentration and the decrease of the oleic one in both species.[PUBLICATION ABSTRACT]
