I posted on Dr. Enlander's wall last night, and got this response:
I've sent for a starter pack of MAF 878. I plan to make a quarter of it up, and start at a quarter dose or less per day. I have 2 questions.
Do I have to throw out any unused yogurt at the end of a month? If not, how long does it stay viable?
If I add colostrum (what form and how much?), can I use my made-up MAF 878 as a starter for the next batch?
Derek Enlander It should last for 2 months.
Derek Enlander THE probiotic bacteria do not replicate continuously for more than six weeks.
A lot of us have asked the second question, and nobody has been answered.
