title: Effect of sodium chloride and potassium chloride on growth response of yeasts Saccharomyces uvarum and Kloeckera brevis to free vitamin B6.
abstract: Acid hydrolysis is the most commonly used extraction procedure for the microbiological assay of vitamin B6 in food samples. Because NaCl or KCl is formed as a result of the extraction procedure, these 2 salts were tested as possible agents that may influence the growth response of the yeasts Saccharomyces uvarum and Kloeckera brevis. Results indicate that NaCl and KCl do effect the growth response of these 2 yeasts, depending on the salt concentration and the B6 vitamer present.
