Abstract The recurrent pattern of oxidative food usage by microorganisms and oxidative destruction of cell substance in unfed cultures has been described, and it has been noted that these phenomena are essentially similar in natural stream purification and in activated sludge and trickling filter systems. The universal effect of nutritional deficiencies on growth characteristics has been described and the effect of nutritional deficiencies on growth and oxidation analyzed. The sewage treatment plant has been noted to undergo a daily cycle with excess oxidation capacity at night because of reduced load. Algal photosynthesis has been analyzed in terms of its effect on oxidative purification processes. (Author)
