Supplementation of Media with Yeast Culture for Counting Anaerobic Spores

Effect of yeast culture supplementation of alfalfa silage or alfalfa hay fed to lactating dairy cows

A Simple and Rapid Protocol for Producing Yeast Extract from Saccharomyces cerevisiae Suitable for Preparing Bacterial Culture Media

Yeasts, especially Saccharomyces cerevisiae, are one of the oldest organisms with broad spectrum of applications, owing to their unique genetics and physiology. Yeast extract, i.e. the product of yeast cells, is extensively used as nutritional resource in bacterial culture media. The aim of this study was to develop a simple, rapid and cost benefit process to produce the yeast extract. In this ...

Radiation for Certain Anaerobic Bacterial Spores

and only three incorporated inorganic sulfate into their microbial proteins when cysteine was present in the medium. One of these cultures, Lachnospira mvltiparus, incorporated about equal amounts of inorganic sulfate into glutathione and microbial protein when cysteine was present in the medium; but failed to form radioactive glutathione when S35 labeled inorganic sulfate was the only source o...

The influence of recovery media on thermal resistance values of spores of a Putrefactive Anaerobic Bacterium.

Yesair's pork infusion medium, as modified by Wynne and Foster (1948), has been extensively employed in thermal resistance studies of spores of Clostridium species. While this medium is excellent for the recovery of spores of these organisms, it is expensive and laborious to prepare. Recent unpublished data in this laboratory have demonstrated that counts of heat-activated spores of Putrefactiv...
