| Abstract | Ecologic relationships among various lagoon organisms and chemical and physical parameters of the lagoon were attempted. Pure cultures of the purple sulfur bacteria, Chromatium vinosum and Thiocapsa floridana were characterized with respect to optimum pH, temperature, and a variety of organic substrates. Experimental and actual lagoon substrate determinations suggest that the purple sulfur bacteria are predominantly responsible for the utilization of volatile fatty acids from the lagoon. Furthermore, the majority of the BOD in the lagoon may be attributed to these volatile acids. A variety of microbial and chemical determinations were made. (Author) |
