Strain Information

Information
Degrades whey . Produces beta-galactosidase (beta-D-galactosidase). Produces biomass. Produces inulinase (endoinulinase). Produces killer toxin . Resistant to killer toxin produced by Schwanniomyces occidentalis ATCC 44252. Attacks pectin. Thermophilic strain. Biotin and nicotinic acid essential for growth, Pantothenic acid stimulates growth.
