Abstract

The object of this work was to find out whether a mixture of organic acids produced at the first and second stages of lignite oxidation can be used as a substrate for cultivating six yeast cultures belonging to the Candida genus. Succinic acid has been shown to be the best accumulated component in the mixture. When C. guilliermondii VSB-249 was cultivated on succinic acid, its growth was inhibited by alpha-naphthoic acid, 1,2-naphthalene dicarboxylic acid and isophthalic acid. It might be concluded therefore that a mixture of acids produced at the first atage of oxidation can serve as the source of carbon for Candida since it contains less inhibitors than a mixture of acids produced at the second stage of lignite oxidation.
