An assay to detect the presence of the STA1+ gene in diastatic S. cerevisiae strains. The STA1 gene encodes the enzyme that breaks down starch, resulting in re-fermentation and overcarbonated packaged product. We recommend a combination of LCSM plating and PCR for the detection of STA1+ diastatic yeast. Turnaround time is 3 days.

All services require an estimated sample volume of 12oz/355mL, unless otherwise noted.
