Principle and Interpretation

Brent Supplement Mixture (BSM) is recommended for use with the addition in DOB (Dropout Base) or DOBA (Dropout Based Agar) and carbon source for the growth of Saccharomyces cerevisiae. This yeast strain is called budding yeast and is extensively studied microorganism in molecular and cell biology. Brent Supplement Mixture (BSM) is used as an amino acid supplement for all strains of Saccharomyces cerevisiae which supplies the essential nutritional elements for budding yeast cells. It is composed of all the amino acids required for the vigorous growth of Saccharomyces cerevisiae. It can be mixed with yeast nitrogen base (YNB), Ammonium sulphate and an appropriate carbon source (glucose/galactose/raffinose) to produce a media suitable for the growth of budding yeast.
