Description and Uses

Bromocresol purple sodium salt is used to isolate acid-producing bacteria from sauerkraut juice, and lactic bacteria is scalped by morphology and share, then morphological, physiological and biochemical interactions. It can be used as a fluorescent stain to detect yeast cells with plasma membrane damage for dead cell counts.
