The experience I related was in a regional brewery with fine control of the fermentation parameters, rapid turnaround, cylindroconical fermenters in which we were able to crop yeast at the optimal time glycol jacketed yeast storage vessels and so on, so we were able to get twelve on average...

and air should be filtered to 5 micron or better, oxygen if from a clean cylinder should not require filtration, but I do so regardless, as I tend to use O2 from a oxy acetylene rig and I can't vouch for the cylinder's condition. I mostly use filtered air from a standard pancake compressor and...

Sorry 0.5 micron...

Correct, cold storage with low oxygen is the best storage method, splashing and shaking are better than nothing. The nice thing about a 5 micron sintered stainless "stone" is that the diffusion is greater, increasing absorption, or the amount actually in solution. DO NOT aerate if your wort is...

As mentioned in many of these posts, the "storeagability" of different strains varies. One rule is the colder the better, short of freezing, which will damage cells. Viability, the number of live cells in a given number of cells pitched, is one crucial factor. This can be checked by homebrewers...
