cell culture optimization and evaluation of the culture conditions of alpha-L-arabinofuranosidase production by Talaromyces thermophilus, modelling, overview. Wheat bran is the best carbon source. Arabinose and arabitol are strong repressors of enzyme secretion. Except for sodium nitrate, all tested nitrogen sources stimulate alpha-L-arabinofuranosidase production, especially organic nitrogen sources, yeast extract gives the best yields Thermomyces dupontii
