Funky Science Fridays

James Sites might have started Funky Science Friday, but MTF milked it (thanks, James)!

Overview	Thread Starter	Date
Overview of a study that showed that 100% Brettanomyces fermentation had more phenol production than when it was co-fermented with the EC1118 wine strain (maybe due to EC1118 being HCDC+), as well as the gene expression difference in EC1118 when co-fermented with B. bruxellensis which made it compete harder for oxygen, and slightly increased the Brettanomyces growth rate in the presence of EC1118. The change in genetic phenotypes of the EC1118 shows that they are involved in interspecies competition between S. cerevisiae and B. bruxellensis.	Richard Preiss	07/26/2017

Part 1 and Part 2 of a scientist discussing his findings with Brettanomyces and lactic/acetic acid production: more accurately counting pseudohyphal cells using fluorescence capability of a Cellometer, developing a better way that Titratable Acidity to measure acids using HPLC/UPLC-ELSD (TA measurements can be skewed by the presence of other acids), and an interesting observation that Brettanomyces cultures contaminated with a small cell count of S. cerevisiae responded differently to aeration. By not aerating, the Saccharomyces grew more rapidly and sugar was consumed at a faster rate, and by aerating the Saccharomyces growth was limited which allowed the Brettanomyces to out-compete it (and sugar was consumed at a slower rate).
