Changes

Beer adapted strains of ''Brettanomyces'' and lactic acid bacteria have been found to be more difficult to culture on agar than when they are not adapted to the environment. Malt agar has been shown to be more effective at showing growth than other types of agar (Dekkera Medium, Universal Beer Agar, Potato Dextrose Agar, and Beer Agar). [[Laboratory_Techniques#Saccharomyces|YPD]] with 10 ppm Cycloheximide was not tested in the study, but Nick Impellitteri, the owner of [[The Yeast Bay]], reports that this media works well for him <ref>[https://www.facebook.com/groups/MilkTheFunk/permalink/2047731471921723/?comment_id=2047735648587972&reply_comment_id=2047763545251849&comment_tracking=%7B%22tn%22%3A%22R0%22%7D Nick Impellitteri.

In addition, it is recommended that 100 mL samples are taken since beer adapted contaminants are harder to grow on media, and at least 7 days of incubation time should be allowed for ''Brettanomyces'' to show signs of growth <ref>[https://www.tandfonline.com/doi/abs/10.1094/ASBCJ-2008-0917-01 Effects of Beer Adaptation on Culturability of Beer-Spoilage Dekkera/Brettanomyces Yeasts.

Advanced beer-spoiler detection medium (ABD) has been shown as a more effective growth medium compared to other media when attempting to grow beer-adapted bacteria such as hop tolerant strains of ''Lactobacillus'' that don't grow well on other media. See [[Laboratory_Techniques#Lactobacillus.2FPediococcus|Lab techniques]] for more information.
