YEAST EXTRACT PASTE (For Bacteriology)

Yeast Extract Paste is derived from an aqueous extract of yeast cells. It is brownish thick viscous paste having characteristic yeast odour but not pungent smell. It is a rich source of vitamins, amino acids. Yeast Extract is the water soluble portion of autolyzed yeast containing vitamin B complex. Yeast Extract is an excellent stimulator of bacterial growth and used in culture media. The autolysis is carefully controlled to preserve the naturally occurring B-complex vitamins. Yeast Extract also provides vitamins, nitrogen, amino acids, and carbon in microbiological culture media. Yeast Extract Paste is manufactured under controlled condition by concentrating an autolysed solution of yeast cells (Saccharomyces) to achieve minimum 55% solid content, by retaining all the nutritive values. It is suitable for cultivation of various microorganisms, fermentation and other biological products.

Used as a biological culture medium.
