Paper Title:
Isolation and Identification of a Low Density Polyethylene Degradable Bacterium
  Abstract

Polyethylene (PE) is one of the most abundant commercially produced synthetic polymers which have leaded the seriously solid pollution. A Gram positive rod form bacterium T6 has been isolated from the guts of Indian meal moth Plodia interpunctella (Hübner). According to the phenotypic, Physiological and biochemical characteristics, and 16S rRNA gene sequence, T6 is identified as Baccillus megaterium. Scanning electron microscope (SEM) reveals the polyethylene can be degraded significantly by T6 from the LDPE surface. The tensile strength of the LDPE films which is degraded by T6 strain, displays decreasing tendency as the incubation time increase. After 28 days’ incubation, the tensile strength decreases 5.8% and the maximum decrement reaches 18.4%. The difference between the tensile strength value of day 21 and day 28 are not significant (P <0.05). The results indicate T6 strain can degraded the LDPE film.
