“…Furthermore, Psychrobacter species often produce lipase, which has been discussed as a potential enzyme for microbial polymer degradation . Similarly, the genus Oceanosphaera was abundant in subtidal PIOM samples and absent in background water and includes species capable of degrading alkenes and phthalates, indicating their potential role in the degradation of polymers and their additives. , The bacterial genus Bizionia was associated with all segments and observed in high abundance in intertidal PIOM. Members from this genus are commonly present in seawater, coastal sediments, and marine organisms such as fish, corals, sea urchins, sea cucumbers, and cockles. − The abundance of Methylophagaceae (uncultured) was relatively high in background water, yet negligible in the plastic-associated microbiome.…”

The long-term aging of plastic leads to weathering and biofouling that can influence the behavior and fate of plastic in the marine environment. This is the first study to fingerprint the contaminant profiles and bacterial communities present in plastic-associated inorganic and organic matter (PIOM) isolated from 10 year-aged plastic. Plastic sleeves were sampled from an oyster aquaculture farm and the PIOM was isolated from the intertidal, subtidal, and sediment-buried segments to investigate the levels of metal(loid)s, polyaromatic hydrocarbons (PAHs), perfluoroalkyl substances (PFAS) and explore the microbial community composition. Results indicated that the PIOM present on long-term aged high-density polyethylene plastic harbored high concentrations of metal(loid)s, PAHs, and PFAS. Metagenomic analysis revealed that the bacterial composition in the PIOM differed by habitat type, which consisted of potentially pathogenic taxa including Vibrio, Shewanella, and Psychrobacter. This study provides new insights into PIOM as a potential sink for hazardous environmental contaminants and its role in enhancing the vector potential of plastic. Therefore, we recommend the inclusion of PIOM analysis in current biomonitoring regimes and that plastics be used with caution in aquaculture settings to safeguard valuable food resources, particularly in areas of point-source contamination.

Fungal Bioremediation of the Plasticizer Hazardous Compound di-2-Ethylhexyl Phthalate (DEHP) in Urine and Blood Bags

et al. 2023

The hazardous compound di-2-ethylhexyl phthalate (DEHP) is widely used as polyvinyl chloride plasticizer. The present research studied the fungal biodegradation of DEHP contained in blood and urine bags. Soil-plate method was used for fungal isolation from heavily plastic polluted soil using Martin’s and Sabouraud’s agar media, where DEHP was the sole carbon source. Isolated fungal species were identified morphologically according to Moubasher (Soil Fungi in Qatar and Arab Countries University of Qatar, Qatar The Center for Scientific and Research, 1993) as Aspergillus nidulans, Aspergillus niger and Rhizopus nigricans. DEHP concentrations were determined in 1 g of soil, urine bags and blood bags to be 0.92, 2.5 and 2.6 g/l, respectively. Samples of both bags (as a sole carbon source) were artificially inoculated with the isolated fungi and incubated for 20 days. As the time increased, the growth increased where Rhizopus nigricans obtained the highest dry weight in urine bags after 20 days of incubation, while A. nidulans had the highest dry weight in blood bags. Also, a sharp declining of initial pH (6.8) reached 4.7 in urine bags with A. niger growth, while reached 2.5 after A. nidulans growth in blood bags. DEHP% decreased as time increased indicating a continuous DEHP utilization by the three fungal species. Aspergillus niger was the most DEHP degrading fungal species in both bags. Scanning electron microscope examination showed an uniform plastic network in both bags before fungal treatment. While, a microporous network was observed on the plastic surfaces in both bags after fungal treatment due to DEHP utilization. The most DEHP metabolizing fungal species were further identified molecularly using internal transcribed spacer primers to be Aspergillus niger and Aspergillus nidulans with accession numbers MZ832174 and MT919276, respectively.
