OPTIMIZATION OF THE TEMPERATURE DEPENDENT BIODEGRADATION OF POLYTHENESHAILESH PATHAK, A.K. RAY, R. K. VERMA AND V. KUMARAbstract Microorganisms have the ability in the biological degradation of the polythene under the environmental condition. Environmental factors may include the temperature, humidity, moisture content, biological activity, etc. influence the functionality of the polythene. Temperature is also an important factor in determining the rate of biodegradation. This is because microorganisms have the ability to reproduce faster in warmer conditions. Biodegradation of polythene is analyzed after four, and eight weeks of incubation in the laboratory condition at the various ranges of temperature and analyzed the effect of temperature on the rate of biodegradation was also shedied. Degradation of polythene was determined in terms of percentage of weight loss of sample polythene. The maximum rate of biodegradation at the temperature around 43oC was achieved with the 8% weight loss per month. The rate of weight loss increases with the increase in the temperature but up to a specific temperature.
