2011 journal article

Characterization of Hybrid Strains of Saccharomyces pastorianus for Desiccation Tolerance

JOURNAL OF THE AMERICAN SOCIETY OF BREWING CHEMISTS, 69(2), 108–115.

By: J. Layfield n, T. Phister n & J. Sheppard n

author keywords: Active dry yeast; Beer; Dehydration; Saccharomyces cerevisiae; Saccharomyces pastorianus; Viability
TL;DR: The findings suggest that S. pastorianus-Frohberg type is less tolerant to desiccation than either S. cerevisiae or S. bayanus type, and selection of the correct type of S. pastorsiae for use in active dry yeast could reduce the possibility of contamination or extended lag phases leading to stuck fermentations.

Detection and enumeration of Dekkera anomala in beer, cola, and cider using real-time PCR

LETTERS IN APPLIED MICROBIOLOGY, 52(4), 352–359.

By: S. Gray n, H. Rawsthorne n, B. Dirks* & T. Phister n

author keywords: Dekkera anomala; QPCR; real-time PCR; spoilage yeast
MeSH headings : Base Sequence; Beer / microbiology; Beverages / microbiology; DNA Primers / chemistry; Dekkera / growth & development; Dekkera / isolation & purification; Food Microbiology; Malus; Molecular Sequence Data; Polymerase Chain Reaction / methods
TL;DR: A quantitative real‐time PCR assay for detection and enumeration of the spoilage yeast Dekkera anomala in beer, cola, apple cider, and brewing wort is presented as an improvement upon existing detection methods, which are very time‐consuming and not always accurate. (via Semantic Scholar)

Development of a Fluorescent In Situ Method for Visualization of Enteric Viruses

APPLIED AND ENVIRONMENTAL MICROBIOLOGY, 75(24), 7822–7827.
