“…By far, plastic-degrading Bacillus isolated from terrestrial environments are more diverse; for example, B. cereus isolated from landfills showed a 1.78% degradation rate of HDPE in 30 days [ 63 ], and the isolate of B. cereus from cattle manure caused a weight loss of 5.9% HDPE in 83 days [ 64 ]. B. safensis from landfill soil caused 8% weight loss of PLA 1006 in 30 days [ 65 ]. Two strains of B. amyloliquefaciens (BSM-1) and B. amyloliquefaciens (BSM-2) isolated from municipal solid soil showed 11% and 16% degradation rates of LDPE, respectively, after 60 days of incubation [ 66 ].…”

Plastic production has increased dramatically, leading to accumulated plastic waste in the ocean. Marine plastics can be broken down into microplastics (<5 mm) by sunlight, machinery, and pressure. The accumulation of microplastics in organisms and the release of plastic additives can adversely affect the health of marine organisms. Biodegradation is one way to address plastic pollution in an environmentally friendly manner. Marine microorganisms can be more adapted to fluctuating environmental conditions such as salinity, temperature, pH, and pressure compared with terrestrial microorganisms, providing new opportunities to address plastic pollution. Pseudomonadota (Proteobacteria), Bacteroidota (Bacteroidetes), Bacillota (Firmicutes), and Cyanobacteria were frequently found on plastic biofilms and may degrade plastics. Currently, diverse plastic-degrading bacteria are being isolated from marine environments such as offshore and deep oceanic waters, especially Pseudomonas spp. Bacillus spp. Alcanivoras spp. and Actinomycetes. Some marine fungi and algae have also been revealed as plastic degraders. In this review, we focused on the advances in plastic biodegradation by marine microorganisms and their enzymes (esterase, cutinase, laccase, etc.) involved in the process of biodegradation of polyethylene terephthalate (PET), polystyrene (PS), polyethylene (PE), polyvinyl chloride (PVC), and polypropylene (PP) and highlighted the need to study plastic biodegradation in the deep sea.

“…Even within 90 days, the weight loss rate does not exceed 5 % [ 107 ]. Bacterial strains with the ability to degrade PLA include Bacillus safensis PLA1006 , Nocardioides zeae EA12 , Stenotrophonas pavanii EA33 , Gordonia sulfurchicans EA63 , Chitinophaga jiangningensis EA02 , etc [ 108 ]. These strains can form bacterial biofilms on PLA at ambient temperatures and accelerate the enzymatic degradation process of PLA through the secretion of proteases and lipases.…”

“…stercoris, and Bacillus safensis was detected by BLAST analysis of 16S rRNA sequence (1387 bp). B. safensis is known for its ability to degrade PLA [74] but, moreover, it was found by Waquas et al that this strain can degrade 18.6% LDPE in 30 days [75].…”

The exposure of microorganisms to conventional plastics is a relatively recent occurrence, affording limited time for evolutionary adaptation. As part of the EU-funded project BioICEP, this study delves into the plastic degradation potential of microorganisms isolated from sites with prolonged plastic pollution, such as plastic-polluted forests, biopolymer-contaminated soil, oil-contaminated soil, municipal landfill, but also a distinctive soil sample with plastic pieces buried three decades ago. Additionally, samples from Arthropoda species were investigated. In total, 150 strains were isolated and screened for the ability to use plastic-related substrates (Impranil dispersions, polyethylene terephthalate, terephthalic acid, and bis(2-hydroxyethyl) terephthalate). Twenty isolates selected based on their ability to grow on various substrates were identified as Streptomyces, Bacillus, Enterococcus, and Pseudomonas spp. Morphological features were recorded, and the 16S rRNA sequence was employed to construct a phylogenetic tree. Subsequent assessments unveiled that 5 out of the 20 strains displayed the capability to produce polyhydroxyalkanoates, utilizing pre-treated post-consumer PET samples. With Priestia sp. DG69 and Neobacillus sp. DG40 emerging as the most successful producers (4.14% and 3.34% of PHA, respectively), these strains are poised for further utilization in upcycling purposes, laying the foundation for the development of sustainable strategies for plastic waste management.
