Newsgroup,
I need some help, I use a vitamin defined media to grow lipoic acid
deficient bacteria. KPO4 is the buffer and charcoal treated casein is a
major component. I have made this media many times with no problems
until recently. Now I get what I think is CaPO4 precipitating when the
pH is adjusted. All reagents I have used before. It's got me baffled,
any suggestions.
Thanks in advance
