Choline Kinase from Brewers’ Yeast

Choline kinase was purified approximately 300-fold, in 5% yield, from an autolysate of dried brewers’ yeast. A molecular weight of 67,000 was estimated using a Stokes radius of 33 A, as determined by Sephadex G-200 chromatography. An s~,,,~ of 4.8 S was obtained by sucrose density gradient centrifugation. Enzyme activity was diminished by sulfhydryl inhibitors and stabilized by the presence of ...

Stimulation by potassium ions of the growth of Rhizopus oligosporus during liquid-and solid-substrate fermentations.

Soya beans and several other beans and cereals have been used as substrates for tempe fermentation with the fungus Rhizopus oligosporus Saito. Except for the presence of alkaloids, the chemical composition of lupins (Lupinus mutabilis Sweet) is similar to that of soya beans. Therefore the potential of lupins for tempe production in regions with a long tradition of lupin consumption is promising...

Pseudoporphyria associated with consumption of brewers' yeast.

A case of pseudoporphyria associated with excessive consumption of brewers ' yeast was studied. Detailed analysis of the yeast tablets by high performance liquid chromatography showed the presence of dicarboxylic deuteroporphyrin , mesoporphyrin, and protoporphyrin; coproporphyrin I and III isomers; and uroporphyrin I and III isomers. The faecal porphyrin concentration of the patient taking yea...

Growth and feed utilization of goldfish (Carassius auratus) fed graded levels of brewers yeast (Saccharomyces cerevisiae)

In this study, a feeding trial was conducted to examine the potential of replacing fish meal with brewers yeast in practical diet of goldfish (Carassius auratus). Five isoproteic (37% CP) and isocaloric (3350 kcal/kg) diets were formulated to contain graded levels of brewers yeast. Fish meal protein was replaced by 0%, 15%, 25%, 35%, and 45% of yeast. Each diet was randomly allocated to triplic...
