Description
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.
This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
