Synthetic plastics are important in many branches of industry. Although synthetic plastics provide numerous benefits, they also cause a significant environmental pollution problem because of their non-readily-biodegradability. Biodegradation may provide solution to the problem, but not enough is known about the biodegradation mechanisms of synthetic plastics. This review has been written to provide an overview of the current state of synthetic plastics (polyethylene, polyurethane, nylon, polyvinyl alcohol) biodegradation. Several biodegradation mechanisms of a few selected synthetic plastics are also presented.

On purpose to examine the various properties of isolates from animals we have sampled feces from the rectum of 100 heads of dairy cattles at N farm: near our university using swab methods as a primary examination and 11 strains of isolates have used In Our tests. The results were summarized as follows : . Isolates were identified as 5 strains of E. coli, 4 strains of Enterobacter, 1 strain of Salmoneella and 1 strain of Citrobacter respectively. 2. All of 11 strains used in our tests could not grow above 75°C for 4.5 minutes. 3. MIC of isolates to 7 kinds of antibiotics were different according to strains and antibiotics used in this test. All of 11 strains to LM and CL were highly resisted and they could grow above 100mcg per milliliter in these antibiotics. Specially MIC of Salmonella to AP, LM, CL, KM were above 100mcg per milliliter.
