The yeast cultivation station will experiment with raising yeast in an open vat. Various sugars and starches sourced from the integrated system will feed the yeast which will in turn feed invertebrates. Keithjd21 (talk) 04:16, May 8, 2013 (UTC)
Considering adding some complexity to the yeast system. I would move the open vats to semi closed vats, basically empty plastic milk jugs with a hole cut in the lid for CO2 escape. This would permit easy agitation by shaking. Future adjustments would be a closed vat system to produce alcohol. The alcohol would be targeted for distillation to produce a burnable fuel. I guess you could drink it but it would basically be prison hooch as the goal is yeast production and not flavor. Likely to be nasty tasting stuff. Keithjd21 (talk) 08:57, July 4, 2013 (UTC)
The soup from the process appears to have no effect on yeast growth. The potato results in a nice frothy mash. I will try experimenting with frozen/unfrozen/cooked/uncooked combinations next to see if it is worth the trouble and energy expenditure. Keithjd21 (talk) 00:04, July 3, 2013 (UTC)
The frozen potato was cooked overnight in a one pint crock pot. I added some of the mush to two containers seeded with my yeast culture. To a third I added some of the fluid from the crock. And to a third I added some fluid to go with the potato mush. I'll observe which yields the fastest replication of yeast and proceed accordingly. Carrot starches might be targeted next.
I also moved the experiment outside to the back room on the garage because it was producing an odor that was less than pleasant. An ozone generator may be in order. Keithjd21 (talk) 20:53, June 28, 2013 (UTC)
I pitched yeast tonight in a sugar water solution. A potato is freezing to break down starches into sugars. I will keep one vat working with cane sugar and use it a culture source to see how the yeast fares on potato. I will probably try rice next as it is very high in carbohydrates and will store more easily than potato. Brine shrimp are the target consumer of yeast. Keithjd21 (talk) 00:48, June 24, 2013 (UTC)
