I found this: Yeast Growth On Lactate The introduction summarizes the ability of yeast to grow on lactate, and mentions a lactate dehydrogenase that is expressed under anaerobic conditions. I agree that a molecule used as a surrogate electron acceptor likely wouldn't be metabolized in the...

Thanks for the replies. I put down a large post on another thread in which I worked through the math on phosphoric acid; long story short, it seems that even at the calculated concentration, I won't be making a large change in the phosphorus concentration.

Two questions: First, if the phosphorus is biologically available (and since HnPO4 buffers are what most folks use for microbiological growth media, I assume that they are), won't the yeast incorporate some fraction of the phosphorus into the multitude of biological molecules which need...

I'm from Galveston Texas. I have two broad questions, but bear with some background information first: 2016 Water report: Ca 2+ 37 Mg 2+ 7 HCO3 - 127 SO4 2- 38 Na + 37 Cl - 51 pH 8.1 (their measurement) pH 7 (my presumably much less accurate measurement at the faucet) I only...

I went a different route. I bought a dual tap pillar and then drilled the top of the lid. I haven't seen many people do that, but it works for me. I can post pics if you like.

I'm a relatively new brewer from Galveston, Texas. My chief interest is in perfecting an all-wheat saison; I don't branch out much from that. I typically brew in 12 gallon all grain batches with a BIAB setup. I just finished a 4 keg keezer and have been kegging/force carbing from day one. I...
