Just a quick response would be greatly appreciated....

1-What is type of yeast used to sprinkle on a ff culture?

2-Does this act as food and/or extend the life of the ff culture?

3-At what point within the culture's development do you add this? How much?

Thanks, Tommy

there are two types of yeast added to the cultures. The first kind in nutritional or brewer's yeast as this increases the protien content of the media allowing for better production. The second type is active or baker's yeast which is alive. This is added to encourage a more rapid deposition of eggs and to help prevent contamination of the cultures by competing microbes. The flies used to seed the culture will bring thier own yeasts into the culture on thier bodies which will take over the culture so the second type isn't universally used by some hobbyists but it can help when you are getting started. After more than 17 years I still use it.

oh, thanks Ed.

Will the typical store bought (fleischmann's) yeast work?

Do you add it before, or during the culture's production?

Fleishmann's active yeast works just fine. As long as it says active (live yeast), it is fine. You add it right before you add the other material(s) like the excelsior or the flies. You shouldn't need to add it again later.

Josh's media only requires, you to use yeast if you don't start a culture with their FF's. Your FF's must carry over the yeast to new cultures.
