Abstract:

A broad spectrum microbial culture similar to activated sludge in utilizing cellulose was evaluated for its ability to utilize wastes. The metabolism of cellulose was followed in Warburg and substrate depletion studies by utilizing measurements of chemical oxygen demand. Activated sludges were developed on cellulose as a sole carbon source and on human waste with added cellulose designed to simulate the waste which would be received in a remote environment. From the Warburg and substrate depletion studies, constants of first-order oxidation rate were obtained. The first-order oxidation constants were found to vary between 0.0133 and 0.0146 reciprocal hours. It was observed that a lag period varying from 400 to 1,500 minutes preceded the utilization of cellulose by the microbial system. Author
