Abstract Plastic pollution is an increasing worldwide problem urgently requiring a solution. While recycling rates are globally, only 9% of all plastic waste has been recycled, and with the cost limited downstream uses recycled plastic, alternative needed. Here, we found that expanded polystyrene (EPS) promoted high levels bacterial biofilm formation sought out environmental EPS to characterize these native communities. We demonstrated attached communities had degrading activity. then...
The successful enzymatic degradation of polyester substrates has fueled worldwide investigation into the treatment plastic waste using bio-based processes. Within this realm, marine-associated microorganisms have emerged as a promising source polyester-degrading enzymes. In work, we describe hydrolysis synthetic polymer PET by SM14est, polyesterase which was previously identified from Streptomyces sp. SM14, an isolate marine sponge Haliclona simulans. hydrolase activity purified SM14est...
Many marine bacteria produce extracellular enzymes that degrade complex molecules to facilitate their growth in environmental conditions are often harsh and low nutrients. Marine bacteria, including those inhabiting sea sponges, have previously been reported be a promising source of polyesterase enzymes, which received recent attention due potential ability polyethylene terephthalate (PET) plastic. During the screening 51 bacterial isolates for hydrolytic activities targeting ester polyester...
Carboxylic ester hydrolases with the capacity to degrade polyesters are currently highly sought after for their potential use in biological degradation of PET and other chemically synthesized polymers. Here, we describe MarCE, a carboxylesterase family protein identified via genome mining Maribacter sp. isolate from marine sponge Stelligera stuposa. Based on phylogenetic analysis, MarCE its closest relatives belong marine-associated genera Cytophaga-Flavobacterium-Bacteroides taxonomic group...
Many marine bacteria have evolved to produce a range of extracellular enzymes which facilitate their growth and survival in the harsh, oligotrophic conditions often present environments. Marine sponge derived Streptomycesstrains previously been reported polyesterase enzymes, are interest for several biotechnological applications, including polyethylene terephthalate (PET) plastic hydrolysis. Bacteria isolated from sponges seaweed were screened polyester hydrolysis activities using...
