Dietary supplement wastewater contains higher order polysaccharides such as the complex sugars maltodextrin and low fat milk. These complex sugars contain a significant amount of organic carbon; therefore, presence of these sugars can pose threats to the environment if discharged without treatment. While many food processing plants are required to send their waste through wastewater treatment, legislation may require preliminary treatment of these wastes in order to satisfy the effluent discharge requirements. Because of the high organic carbon presence, it would be preferable to use biological treatment methods to reduce the organics present within the system. Microorganisms are capable of degrading organic compounds present for the purpose of metabolic processes. Therefore, a series of experiments were conducted between the months of May and October 2009 to determine the effectiveness of biological degradation of carbon within various substrates.Preliminary studies were completed between May and July using LLMO (live liquid microorganisms) and baker's yeast to determine the proper substrate capable of microorganism synthesis. All analysis of total organic carbon (TOC) were performed using a Shimadzu TOC Analyzer. Substrates that were used included Kool Aid, Hershey's Cocoa, Gatorade, flour, potato starch, Slim Fast, and Carnation's Breakfast Essentials; however, Hershey's Cocoa and Gatorade

were the only substrates that were not used in measuring organic carbon removal. The calibration curves for those substrates did not have an R2 value above 0.89 and therefore were not used for further observations. From preliminary studies, it was determined that Carnation Breakfast Essentials and Slim Fast produced the highest percent removal of organic carbon. However, Slim Fast was not used due to the difficulties of storage. The primary experiment conducted between July and October involved a comparison between microorganisms and the total organic carbon removal from Carnation Breakfast Essentials. Microorganisms involved in the experiment included four species of LLMO, store bought baker's yeast, brewery's yeast from a local brewery, and two Enforcer products (Liquid Drain Care and Toilet Care) for septic systems. Results determined that LLMO recorded the highest % of total organic carbon removal followed by baker's yeast. Brewer's yeast and Enforcer septic system products were declared ineffective due to the surrounding high concentration of high molecular hydrocarbons-brewer's yeast were collected from fermenting beer, Enforcer Liquid Drain Care contains high molecular hydrocarbons, and Enforcer Overnight Toilet Care consists of sulfate compounds which inhibit reading of organic carbon presence in the samples.
