Webinar Summary

This webinar will compare and contrast laboratory equipment and materials with items purchased at stores open to the average consumer to give brewers an inexpensive alternative for the anaerobic incubation of their brewery samples. We will also evaluate the many microbiological media used by professional brewers, outlined in the ASBC method Microbiological Control 5: Differential Culture Media, and help explain critical topics behind the utilization of these tools.​



ATTENDEES WILL LEARN:​


This session will begin with a review of what equipment is currently available for total plate count analysis, as well as commonly used microbiological media, so attendees will have a good understanding of current industry practices.

Following this review, there will be a deep dive into how Yeast-Peptone-Dextrose (YPD) agar can be used for a variety of applications via the introduction of small concentrations of selective compounds, such as cycloheximide and Cupric Sulfate, and how those compounds will influence growth in the media. 

Attendees will also get a recipe for YPD agar based on grocery store available items, and a comparison of how the over-the-counter ingredients compare to the industry-available version (Sigma-Aldrich).
