Biogas is a clean conventional source of energy for the rural community. The anaerobic digestion is a technology used for recycling organic materials. In the present work, a floating type biogas digester is constructed and used to evaluate the quantity of produced gas, in addition, to determine its chemical composition. To examine Microbiological analysis, different samples are obtained from the floating type fermenter unite. Total solids, nitrogen carbon content and PH is determined from analysis of a cow dung samples. The obtained results show that, the total produced gas is found to be about 101.7 liters and the initial pH in fresh cow manure sample was 8.1, this value decreased during fermentation period until reached to 4.8 inside digester. The experiment is conducted at low temperatures range between 15 °C and 23°C in a batch mode. Microbial load is determined also from the digested.
