Plate assay of thiamine. I. Using Kloeckera brevis.
Lactobacillus fermenti strain 36 is the most frequently used microorganism for the assay of thiamine both in the tube method, (Sarett and Cheldelin, 1944; Fitzgerald and Hughes, 1949), and in the plate method, (Bacharach and Cuthbertson, 1948; Jones and Morris, 1949). Other microorganisms have more recently been suggested for the tube assay; Hoff-Jorgensen and Hansen (1955) used the yeast Kloec...
متن کاملStudies with the Agar Cup-Plate Method: I. A Standardized Agar Cup-Plate Technique.
Official Circular 198 (Ruehle and Brewer, 1931) gives directions for performing the agar cup-plate test. However, in the limited literature dealing with the subject, no mention is made of the influence of varying the volume of agar, the amount of inoculum, the hydrogen ion concentration or other factors. In the course of other studies with the agar cup-plate method (Rose and Miller, 1939; Mille...
متن کاملBehaviour of Kloeckera apiculata Flocculent Strain in Coculture with Saccharomyces cerevisiae
The behaviour of the flocculent Kloeckera apiculata strain in coculture with the nonflocculent Saccharomyces cerevisiae strain, both yeasts isolated from wine, has been analyzed. Pure culture of Kloeckera apiculata (apiculate yeast) exhibits 75 % flocculation in the yeast extract/peptone/glucose (containing 20 g/L of glucose, YPG20) medium after 24-hour incubation at 28 °C. This yeast expresses...
متن کاملThe conversion of 3-Hydroxy-2,4,5-trihydroxymethylpyridine into pyridoxine by Kloeckera apiculata.
Kloeckera apiculata, a vitamin B-6-dependent yeast, grows in the presence of 3-hydroxy-2,4,5-trihydroxymethylpyridine in vitamin B-6-free media. On a molar basis the growth-promoting activity of this compound is approximately one-tenth that of other forms of vitamin B-6. [G-3H]3-Hydroxy-2,4,5-trihydroxymethylpyridine is converted into radioactive vitamin B-6 compounds of the same specific radio...
متن کاملInfluence of Culture and Nutritional Conditions on Self-Flocculation of a Kloeckera apiculata Wine Strain
The current work examines the environmental conditions to control the expression of self-flocculation of Kloeckera apiculata mc1 isolated from Argentinian grapes with proven beneficial effect on wine aroma. Temperature had a direct effect on the expression of flocculation resulting in an increase in the number of zymolectin sites determined with a BSA-Gal-FITC probe and quantified with the Scat...
