Influence of several parameters on the growth of Candida ingens in controlled batch culture using volatile fatty acids as substrates

Anciaux, C.M. / De Meyer, M. / Levert, J.M. / Vanthournhout, M.

AbstractThe culture of Candida ingens on volatile fatty acid mixtures, C2C6, showed a diauxy phenomenon, straight-chain acids being consumed before branched-chain acids. This diauxy was interpreted as a catabolic repression of the enzymes degrading branched-chain acids. The appearance of propionic acid in the substrate in the first part of the growth was due to valeric acid β-oxidation. The μ vs S curves showed a growth inhibition by the substrate, and a Monod-type kinetics accounted for the dissolved oxygen influence. The best growth rates and yields obtained were, respectively, 8 per day and 0·60 g dry biomatter/g substrate consumed.
