Two aquatic environments emphasized in this research, in which algal decay might occur are (1) dark aerobic characterized by the presence of oxygen, and (2) dark anaerobic characterized by the absence of oxygen. As a result of the decomposition of algal matter, nutrients are released to solution, subsequently becoming available for incorporation by other algal cells. The objective of the research was to study the extent of algal decomposition and nutrient regeneration. A correlation was found between the initial characteristics and the refractory organic fraction of algal cultures. This is important because the refractory fraction represents that portion of algal organic matter that does not significantly adversely affect the oxygen resources of surface waters under any conditions.
