Trophic Interactions of Proteolytic Bacteria Proteinivorax tanatarense in an Alkalinphilic Microbial Community.

Lythic action of an anaerobic proteolytic bacterium Proteinivorax tanatarense on organisms with different cell wall types was studied. In the absence of photosynthetic oxygen release, this proteolytic was able to grow on intact biomass of cyanobacteria belonging to various systematic groups. Itis probably their usual saprotrophic-satellite responsible for the regulation of abundance of primary producers during the dark phase.
