New forms of yeast culture propagation.

Many forms of culture.

Psychologists interested in culture have focused primarily on East-West differences in individualism-collectivism, or independent-interdependent self-construal. As important as this dimension is, there are many other forms of culture with many dimensions of cultural variability. Selecting from among the many understudied cultures in psychology, the author considers three kinds of cultures: reli...

Use of Yeast Culture in the TMR of Dairy Holstein Cows

The aim of this study was to determine the effect of yeast culture (Saccharomyces cerevisiae SC 47) addition in the diet of dairy cows on their rumen fermentation and milk production. Animals received a diet TMR based on good maize silage with a higher dry matter content (14 kg), 14 kg of lucerne-grass haylage, 5 kg of crushed ears of maize, 5 kg of beet pulp silage, 3 kg of crimped wheat, 2 kg...

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

Chemostat Culture for Yeast Physiology.

The use of chemostat culture facilitates the careful comparison of different yeast strains growing in well-defined conditions. Variations in physiology can be measured by examining gene expression, metabolite levels, protein content, and cell morphology. In this protocol, we show how a combination of sample types can be collected during harvest from a single 20-mL chemostat in a ministat array,...

Isolation of L-forms by blood culture.

Culture media for the isolation of bacterial L-forms from the blood were studied. The most successful media had an osmolality of more than 1100 mosm/kg and this appeared to be a critical factor in determining success.
