NCYC offer an extensive range of yeast evaluation services to provide the brewer with a comprehensive profile of their production yeast:

• DNA profiling
• Purity Tests
• Cell and colony morphology
• Ale/Lager differentiation tests, including Melibiose fermentation test and growth at 37°C
• Semi anaerobic fermentation tests including Maltotriose fermentation

Wild Yeast contaminant characterisation:

• Plate tests
• DNA sequencing
• DNA Fingerprinting

Please contact us to discuss how NCYC developed evaluation services and additional quality control checks can benefit the performance of your yeast strain.
 

DNA Sequencing - Identification 

DNA sequence analysis, of the variable D1/D2 region of the nuclear-encoded 26S ribosomal DNA (26S rDNA), is recommended for rapid and accurate species identification. This DNA-based method can be used reliably to identify commonly encountered food and beverage spoilage species (e.g. Dekkera, Saccharomyces and Zygosaccharomyces), environmental isolates as well as putative new species. Species identification typically takes less than 1 week from receipt of a culture (if pure), and a full report including the derived D1/D2 sequence is supplied upon completion.
