MICROBIOLOGICAL WASTE CONVERSION IN CONTROL OF ISOLATED ENVIRONMENTS
Abstract
Results of studies involving variations in the rate of gas flow through an algal culture showed that doubling the rate of flow resulted in a 45 percentage increase in the over-all visible light energy conversion efficiency of the culture. Experiments with the modified unit showed that the ecological system can be maintained in a balanced state for periods in excess of six weeks. Further experimentation with the system showed that it possesses essentially homeostatic properties. A determination of the dynamics of the system indicates that the dynamic part of the transfer function with respect to light input can be mathematically described. Studies on the nutritional characteristics of the algal-bacterial culture in the microterella indicate that nitrogen is the only nutrient not supplied in sufficient amount by the mouse's wastes. Sustained recycling of the culture liquid failed to demonstrate a build-up of toxic material. (Author)
