“…In 2016, eight fungal strains ( Table 6) were showed be able to grow in mineral medium with a polyether PUR varnish as the sole carbon source and degrade 65% of solid polyether PUR foams in 50% potato dextrose broth (PDB) over 21 days (Álvarez-Barragán et al, 2016). Stepien et al found that three bacteria and one yeast ( Table 6) could degrade commercial polyether PUR films (Tecoflex R ) and cause a weight loss of 2.8-10.5% within 5 months (Stepien et al, 2017). Oprea et al assessed the biodegradability of pyridine-based polyether PUR elastomers by a fungus Alternaria tenuissima, and found that the fungus could decrease the mechanical properties and deteriorate the surface morphology after 60 days (Oprea et al, 2018).…”

Anthropogenic activities have extensively transformed the biosphere by extracting and disposing of resources, crossing boundaries of planetary threat while causing a global crisis of waste overload. Despite fundamental differences regarding structure and recalcitrance, lignocellulose and plastic polymers share physical-chemical properties to some extent, that include carbon skeletons with similar chemical bonds, hydrophobic properties, amorphous and crystalline regions. Microbial strategies for metabolizing recalcitrant polymers have been selected and optimized through evolution, thus understanding natural processes for lignocellulose modification could aid the challenge of dealing with the recalcitrant human-made polymers spread worldwide. We propose to look for inspiration in the charismatic fungal-growing insects to understand multipartite degradation of plant polymers. Independently evolved in diverse insect lineages, fungiculture embraces passive or active fungal cultivation for food, protection, and structural purposes. We consider there is much to learn from these symbioses, in special from the community-level degradation of recalcitrant biomass and defensive metabolites. Microbial plant-degrading systems at the core of insect fungicultures could be promising candidates for degrading synthetic plastics. Here, we first compare the degradation of lignocellulose and plastic polymers, with emphasis in the overlapping microbial players and enzymatic activities between these processes. Second, we review the literature on diverse insect fungiculture systems, focusing on features that, while supporting insects’ ecology and evolution, could also be applied in biotechnological processes. Third, taking lessons from these microbial communities, we suggest multidisciplinary strategies to identify microbial degraders, degrading enzymes and pathways, as well as microbial interactions and interdependencies. Spanning from multiomics to spectroscopy, microscopy, stable isotopes probing, enrichment microcosmos, and synthetic communities, these strategies would allow for a systemic understanding of the fungiculture ecology, driving to application possibilities. Detailing how the metabolic landscape is entangled to achieve ecological success could inspire sustainable efforts for mitigating the current environmental crisis.

“…For that reason, they are used in medicine and different industrial products, such as foams, adhesives, construction materials, fibers, and coatings. 4 PUs have become a fundamental material in human life because their versatility allows them to be used as a substitute material to create several products. For that reason, the consumption of this plastic has increased worldwide and, therefore, its accumulation at the end of its useful life.…”

Polyurethane has been used and over-exploited worldwide in the manufacture of different goods, but it is hard to break down and represents an important contaminant due to its accumulation when discarded. Recent research findings have shown that several bacteria and their enzymes can biodegrade various plastics, such as polyurethane. In this review, we sought to group, analyze, and relate the techniques used by different bacterial species to biodegrade polyurethane that have been identified in different studies by searching databases, such as PubMed, Web of Science, and Scopus. Different species of proteobacteria, actinobacteria, and endobacteria biodegrade polyurethane by oxidation and hydrolysis to obtain carbon and nitrogen sources. Changes as weight loss, tensile strength, and chemical and surface changes were observed in polymer properties, showing that biological technologies have a direct impact on polyurethane by modifying the molecule in different ways.
