Biodegradation Of Plastics By Pseudomonas Putida Isolated From Garden Soil Samples

An attempt was made to isolate Pseudomonas putida from garden soil samples and to characterize its degrading ability on plastic material. This work reveals that the garden soil is a good source of microbes capable of degrading plastic materials. P. putida have the ability to convert the complex plastic material was determined in terms of weight loss of the material. It degrades the plastic material up to 75.3% within a month. The plastic samples tested in this study were polythene bag, plastic bag, plastic cup and milk cover. Among the plastic samples, milk cover was found to be more degradative (75.3%) plastic material.
