Pectin derived from sugarbeet pulp is extracted and then subjected to either enzymic or chemical modification. The enzyme is derived from the fungus Aspergillus niger . A partial purification of the enzyme yields a preparation which is devoid of poly

Flocculent yeast cells have an absolute requirement for mechanical energy input in order for flocculation to occur. Flocculation is arrested by cessation of energy input. The initial rate of flocculation increases as the square of the cell concentrat

SUMMARY: A comparison was made of kinetics of solute accumulation by Saccharomyces cerevisiae NCYC 366 grown anaerobically under conditions that lead to enrichment of the plasma membrane with ergosterol and either oleyl or linoleyl residues. Values f

Weak acids and hydrogen ions in different concentration combinations affect the intracellular pH value (pHi) of Zygosaccharomyces bailii. The lowest pHi value measured was not at the most extreme, but at intermediate conditions of inhibition. Proton

SUMMARY: At concentrations up to 1 mM, l-asparagine was accumulated by Saccharomyces cerevisiae X-2180 at 30 °C against a concentration gradient. Values for K T and V max were, respectively, 3.5 x 10-4 M and 33 nmol (mg dry wt)-1 min-1. At concentra

SUMMARY: Saccharomyces cerevisiae Y185, enriched in linoleyl residues and incubated for up to 4 h in derepression buffer, more rapidly acquired general amino-acid permease (GAP) activity, as measured by the rate of accumulation of l-alanine, compared

SUMMARY: Saccharomyces cerevisiae Y185, grown anaerobically in media containing ergosterol and palmitoleic, oleic or linoleic acids, synthesized phospholipids extensively enriched in the exogenously supplied fatty acid. A study was made of the effect

Yeast flocculation is an orthokinetic process dependent upon mechanical agitation for all quantitative measurements. From several methods which were assessed, orbital shaking was selected as being the most practical as well as producing the most mean

In completely randomised factorial experiments, individual and synergistic effects of pH, benzoic acid and sorbic acid on the growth rate of the yeast Zygosaccharomyces bailii were determined, and expressed in polynomial equations. Synergism between
