Analysis of the plastic-degrading bacteria utilization

The environmentally friendly method of plastic degradation has always risen lately to be a topic of interest in society. This is due to the tendency of synthetic polymers to resist degradation in the natural environment and being left in the environment untreated in a continuously increasing volume....

description The environmentally friendly method of plastic degradation has always risen lately to be a topic of interest in society.
