Bacteria as food

[scyphozoa]

I have often read that sponges, corals, and other reef creatures may consume bacteria as food. In theory is there a type of bacteria (non-pathogenic of course) that one could culture and add a suspension of to the water to feed occasionally. (I was thinking this may be useful in tank dedicated to sponges or other) Any marine microbiologists out there?

Bakers or brewers yeast, Saccharomyces spp., is readily available, easy to culture (sugar water), and have not been reported as facultative pathogens of fishes. Yeast has been used for years to feed brine shrimp and enrich nauplii, I would think it work work well as a food for filter-feeders, though I have never tried it.
