Effect of Acids and Sorbate Combinations on the Growth of Four Osmophilic Yeasts.

The effects of hydrochloric, citric, lactic, phosphoric and malic acids in combination with potassium sorbate on the growth of Saccharomyces bailii , Saccharomyces acidifaciens ( Saccharomyces bailii var. osmophilus ), Saccharomyces rouxii and Saccharomyces bisporus were evaluated. Double strength potato dextrose broth supplemented with 58% (wt/vol) sucrose, 14% (wt/vol) glucose, and 0.

Growth Response of an Osmotolerant Sorbate-Resistant Yeast, Saccharomyces rouxii , at Different Sucrose and Sorbate Levels.

Effects of preconditioning Saccharomyces rouxii to various sucrose and sorbate concentrations were investigated. Cells were preconditioned to 0 and 60% (wt/vol) sucrose without and with 0. 1% (wt/vol) sorbate by a series of four transfers in potato dextrose broth (PDB).
