Abstract
The use of Petroleum-based plastics has steadily increased which leads
to a significant environmental problem. In the current study, bacteria were
isolated from the soil samples of 4 different plastic waste dump sites of Darjeeling.
A total of 943 bacteria were isolated from the soil samples by using standard
microbiological procedures. The isolates were characterized by various
morphological and biochemical tests. After the identification of isolates, 20
isolates were selected for their examination for plastic degradation ability. Isolates
were studied for their PVC degrading ability in terms of weight loss percentage.
The bacterial isolates were identified as Streptococcus (7), Micrococcus
(6), Staphylococcus (5) and Bacillus (2). These isolates were
checked for their ability of plastic degradation. Biodegradation of the plastic
was checked in nutrient medium. The three bacterial isolates that showed degradation
of PVC strips were Staphylococcus aureus, and two strains of Streptococcus.
These isolates decreased the weight of plastics by 4mg, 2mg and 4mg respectively.
