Merck, MHA00BSM2, Brettanomyces Selective Broth

General description
Brettanomyces Selective Broth is a medium used for the enrichment of Brettanomyces of wines. Brettanomyces is a genus of yeast capable of growing in high concentrations of alcohol and of fermenting sugars that have not been used by Saccharomyces cerevisiae during fermentation.{20} The presence of Brettanomyces is associated with the appearance of strange wine aromas. Dextrose is the fermentable carbohydrate providing carbon and energy. Peptone and malt extract provide nitrogen, vitamins, minerals and amino acids essential for growth. Yeast extract is source of vitamins, particularly the B-group. Thiamine is a growth factor. Selective agents are added to improve Brettanomyces recovery through the inhibition of common contaminants as Saccharomyces cerevisiae. Colonies appear small, white, creamy and very convex, almost semi-spherical. A halo can appear around the colony due to acid production
