Polystyrene microplastic degradation by a novel PGPR Bacillus spizizenii
This study explores the novel use of Plant Growth Promoting Rhizobacteria, Bacillus spizizenii as a Polystyrene Microplastic (PS-MP) degrading agent. An impressive 85.86 % MP degradation efficiency was reported over a span of 30 days when Polystyrene (PS) was used as an exclusive carbon source. Fourier transform infrared spectroscopy (FTIR) confirmed the significant alteration in PS-MP peak intensities, indicating the breakdown of PS. Further, PS surface degradation was clearly visible in scanning electron microscopy (SEM) imaging. The metabolic analyses were performed after 30 days using Gas Chromatography-Mass Spectrometry (GC-MS). Using these metabolic data references in the KEGG database of Bacillus spizizenii potential degradation pathways were outlined. The PGPR traits of Bacillus spizizenii were confirmed by Indole Acetic Acid (IAA) Production, Phosphate solubilization, Ammonia, Hydrogen Cyanide (HCN), and Siderophore production. The results provide a novel candidate for PS degradation. The PGPR qualities further make it feasible for the use of plastic-polluted soil restoration.
期刊介绍:
The Journal of Hazardous Materials serves as a global platform for promoting cutting-edge research in the field of Environmental Science and Engineering. Our publication features a wide range of articles, including full-length research papers, review articles, and perspectives, with the aim of enhancing our understanding of the dangers and risks associated with various materials concerning public health and the environment. It is important to note that the term "environmental contaminants" refers specifically to substances that pose hazardous effects through contamination, while excluding those that do not have such impacts on the environment or human health. Moreover, we emphasize the distinction between wastes and hazardous materials in order to provide further clarity on the scope of the journal. We have a keen interest in exploring specific compounds and microbial agents that have adverse effects on the environment.
