Strains of Saccharomyces cerevisiae ferment slowly and give beer of high specific gravity in nutrient-depleted worts produced by substituting carbohydrate syrup for malt. Yeast performance cannot be fully restored by the provision of increased quanti

A commercially produced system for the identification of Lactobacillus, by which the reactions of concentrated cell suspensions towards 50 substrates may be determined, is useful for the characterization of strains of Pediococcus. Suitable conditions

The addition to wort of lipids derived from malt spent grains had a pronounced effect on yeast metabolism. The lipids allowed the fermentation of de-oxygenated wort and also stimulated yeast growth and the corresponding rate and extent of fermentatio

In batch fermentations, carried out using a range of conditions, the specific rate of sugar utilization is shown to decline throughout. When yeast mass is increasing, the yield coefficient relating carbohydrate utilization to mass production remains

The sterol contents of brewing yeasts harvested from an anaerobic fermentation and inoculated into air-saturated wort rise rapidly from ca. 1 mg/g dry yeast to ca. 10 mg/g and remain at this level until the oxygen is absorbed. After all oxygen is rem

The content of sterols in Saccharomyces cerevisiae which has been harvested after anaerobic growth and then added to a complex nutrient medium, rises rapidly from ca. 1 mg/g dry yeast to ca. 10 mg in the presence of dissolved oxygen. A range of stero

Sucrose agar is a relatively simple and inexpensive medium which gives good growth of a wide range of cultures of the Lactobacilli and Pediococci encountered in breweries and also of representative strains of other spoilage organisms. It may be used

Relatively rapid and simple methods for measuring the content of the free C6-C10 fatty acids in fermenting wort and beer and of the total C6-C18 fatty acids in yeast are described. The acids are extracted, after saponification in the case of yeast, u

The medium chain length fatty acids that are excreted during fermentation are produced by synthesis and not by degradation. The fermentation of a wort supplemented with propionic acid (C3) or valeric acid (C5) leads to the excretion of nonanoic acid
