Abstract
The present research was directed to exploit the potential bacterial and fungi strains for the biodegradation of Polyisoprene (Natural Rubber). In current study, twelve different bacterial strains were isolated from the sewage sludge sample through enrichment and soil burial techniques. The microbes isolated from the samples showed good growth and biodegradation activities on culture medium. Later on these strains were identified and characterized on the basis of morphological and biochemical test. Among these, seven were Bacillus, three Aerococus and two were Staphylococcus sp. Consequently, two fungal strains were also identified and named as Aspergillus sydowii and Aspergillus candidus. Biodegradation activates of the mixed culture of microrganism were monitored through UV spectrophotometer and functional groups changes were analyzed through FTIR spectroscopy. Fourier Transform Infrared Spectroscopy (FTIR) (Bio-Rad Merlin) analysis displayed the changes in the region 1200-1400 cm-1 representing the degradation of Polyisoprene rubber after culturing in liquid media. CO2 evolution in Sturm test was gravimetrically calculated as 42.88 g/l in case of test. However 20.58 g/l in case of control was noted. The difference in amount of CO2 produced both in test and control indicated the degradation of rubber. This study determined that a mixed microbial culture had a potential tendency toward the degradation of rubber.Biography
