Strain Information

This strain is recommended for studies involving Saccharomyces cerevisiae

This is a brewing production strain

NCYC Number:	240
Name:	Saccharomyces cerevisiae
Depositor:	B.M. Brown
Deposit Name:	Saccharomyces cerevisiae
Deposit Month:	June
Deposit Year:	1951
Equivalent Strain Designations:	Whitbread Taylor Walker Yeast SC12. ATCC 44953, MUCL 30938.
Habitat:	Ale production yeast.
References:	Woods LF , Wiseman A . Benzo(a) pyrene hydroxylase from Saccharomyces cerevisiae. Substance binding, spectral and kinetic data. Biochim. Biophys. Acta 613: 52-61, 1980. Restriction analysis of 2µ plasmid, J.Inst.Brew., 1982, 88, 7-10.
Information:	Produces benzopyrene hydroxylase [benzo(a)pyrene hydroxylase] O3, DMS 63 µg/l, high pyruvic, low acetic, S.G. 6.9, pH 3.91 used in BRF brewery where it has proved a stable yeast. Fermentation stops at 1012 in batch fermentation; no rising gas bubbles to keep it in suspension. Produces very rough variants which can form 20% of the population and do not assimilate maltotriose. Maltotriose is fermented relatively slowly by the normal strain. (See NCYC 753 & 754).
