Biodegradation of polypropylene by bacterial isolates from the organs of a fish, Liza grandisquamis harvested from Ohiakwu estuary in Rivers State, Nigeria.
AI summary Read the abstract
This study isolated bacteria from the organs of mullet fish and confirmed their ability to biodegrade polypropylene using gravimetric weight loss and infrared spectroscopy. Multiple bacterial species native to a coastal estuary demonstrated plastic degradation capacity.
Biodegradation of polypropylene (PP) by bacteria isolated from internal organs of mullet, Liza grandisquamis were assessed using gravimetric (weight loss) and Fourier transform infrared (FTIR) spectroscopy analyses. Bacterial isolates; Staphylococcus epidermidis (AE015931), Pseudomonas xiamenensis (MH734834), Bacillus licheniformis (AF478085), Klebsiella pneumoniae (MH021669), Bacillus lentus (AB021189) and Escherichia coli (KX609714) were screened for capacity to degrade PP, respectively. From the data obtained the degradation of PP occurred in the following order; Bacillus lentus > B. licheniformis > Staphylococcus epidermidis > Klebsiella pneumoniae > Escherichia coli overtime. However, further research would be needed to understand clearly the mechanism of biodegradation of PP and the applicability of these bacteria on related synthetic polymers. The standardized protocols for the biodegradation of PP are also required.
