Re: Raising Daphnia - Flour and Alcohol
Matt said, in part:
"The only reason that I can think of for not using activated yeast is if
you are also using FLOUR to feed your Daphnia. Yeast + flour will start
a fermentation, producing alcohol, that eventually will kill the Daphnia."
Well, not in my experience. I've been raising daphnia for at least 4 years
on a soy flour - yeast mixture and it's worked great! I've never had a
die-off.
Can you furnish a reference? Yeast is a common ingredient in many foods.
I don't know much about the production of alcohol; I'm more at the consuming
end.
I do know that it is a chemically complex process, but it all seems to start
with the fermentation of sugar. To make it you need a lot of sugar or its
equivalent, and I'm sure that the soy flour - yeast - daphnia water doesn't
produce enough to cause any problems, if it produces any at all.
In my original post I said that the "how do I feed daphnia" question always
seemed to produce controversy. Well, ...
Good luck!
