Description

General description

Yeast Autolysate is prepared by drying the extract from autolysing yeast cells (Saccharomyces) which is a good source of amino-nitrogen and vitamins, particularly the water soluble B- complex vitamins. Its addition to many media or fermentation broths increases the yield of organisms and is recommended where rapid and luxuriant growth is required.
