Comparison between the content of all soluble carbohydrates present in distinct fractions of the yeast Saccharomyces cerevisiae

Strains of Saccharomyces cerevisiae were quantitatively compared to the content of all soluble carbohydrates present in two kinds of fraction: the "washed" and the lysate fraction with the purpose of identifying the richest fraction to be used in programs of induction of disease protection in plants. The sugar contents in the "washed" fraction were related to residues from the culture medium and not to extracellular components. Preliminary assays determined criotrituration as an adequate method of cellular lysis. Relevant observation has been made regarding to the variability of all sorts of carbohydrate content present in the lysate fraction of different strains.
