the PLA films were recovered from the culture broth in order to assess the nature of the microbial growth and the surface damage done to PLA film. The film surface was smooth in the control without inoculation of the strain (Fig. 1A), whereas the PLA film, incubated with MS-2 showed large number of pit holes all over the surface of the film and most of the film surface was attacked by the bacilli (Fig. 1B). Similar surface pattern was also observed with isolate MS-1(Fig. 1C) and MS-3 (Fig. 1D) over the PLA films which were flooded with bacilli and budding yeast cells.
