CO2 Reculturing Question & a note of gratitude.

[Dances With Ferrets]

Yet ANOTHER DIY yeast CO2 system question..... when the old solution
in the jar is just about spent, instead of seeding the new solution
with new yeast.... can it just be re-cultured with a little bit of
detritus from the old solution? I was figuring that if this was
possible, a turkey-baster or medicine-dosing syringe might be the best
method of doing this. Any thoughts?

BTW... wanted to let you all know that I've greatly appreciated all
the help and information that I've received so far from this
newsgroup. Especially about the yeast CO2 systems.... I now have two
great CO2 systems up and running on a couple of my "pet project"
heavily planted tank displays at work... and the higher-ups as well as
my coworkers are very impressed. Many thanks to all!!! The plants in
the shop have never done so well.

I've heard that technological progress comes more as a result of people
who ask good questions, than from the people who answer them ;~).

Your's is a very good question (well beyond my limited expertise). You
might try posting in rec.aquaria.freshwater.plants, or sci.aquaria or
rec.aquaria.tech (the last two don't get a lot of traffic though).

I presume that your idea of seeding is to get the 2nd batch fermenting
faster. Typically they start in about a day. Do you think seeding would
significantly accelerate the process (I imagine it might). Good luck!

you can do this with bread, and you can do it with brewing, so I don't
see why it wouldn't work here. With brewing, once all the sugar has
fermented out, you can add more sugar - up to a limit where the alcohol
present will prevent further fermentation taking place. If you wanted to
continue fermenting (I'm imagining a process where CO2 is the end
product and alcohol a by-product, which goes against the grain a
little...) you would need to remove half the alcoholic product and
replace it with a sugar solution. If you wanted to start a new solution
fermenting, you could certainly take the lees (sediment at the bottom)
and add it to something with sugar in to start fermentation, as long as
it hadn't been sitting too long. No different to adding yeast - in fact,
you _are_ adding yeast. This would depend on whether your original
solution was spent because all the sugar had been fermented out or
because the yeast's waste products had killed it off.

I liked the idea mooted in r.a.f.p where brewing and planted aquariums
were combined, myself!
