Hi Ray,

The yeast in this case are dead. They're meant to be a source of nutrients and growth factors. Any that are alive in the brewer's yeast powder will quickly be killed by the boiling or pressure cooking.

Common brewers yeast (Saccharomyces cerevisiae) has only very small amounts of chitin in their cell walls.

The active organism here is whatever you inoculate with right before you turn on the air pump and let it sit. In my case, it's Streptomyces lydicus. I have access to useful Streptomyces griseus and Streptomyces violaceousniger strains, so I will try them as well.

And yes, I did try them on my roses, for active blackspot. Because I didn't have a control, it's hard to draw useful conclusions. But the blackspot did not spread after spraying with it. I had too many roses to really keep it up though.
