Hi Ted,
Very interesting thread and it may take me some time to catch up.
Question: Is there a safe fermentation method ? Which is a good yeast for us? baker's yeast saccharomyces cerevisiae may have some issues.
Ann Rheum Dis. 2003 May; Anti-saccharomyces cerevisiae IgA antibodies are raised in ankylosing spondylitis and undifferentiated spondyloarthropathy.

Rgds.,
Krishna
