“…Polymer biodegradation proceeds in an aqueous environment and is therefore carried out in aerobic conditions, while biodegradation in soil or composting conditions was much slower or completely abolished. Interestingly, bacteria were also shown to discriminate between PVA samples by polymer tacticity, as reported by Fukae et al145 and an isotactic‐rich PVA underwent almost a complete degradation within 6–8 d.…”

Poly(vinyl alcohol), PVA, and physical hydrogels derived thereof have an excellent safety profile and a successful history of biomedical applications. However, these materials are hardly in the focus of biomedical research, largely due to poor opportunities in nano- and micro-scale design associated with PVA hydrogels in their current form. In this review we aim to demonstrate that with PVA, a (sub)molecular control over polymer chemistry translates into fine-tuned supramolecular association of chains and this, in turn, defines macroscopic properties of the material. This nano- to micro- to macro- translation of control is unique for PVA and can now be accomplished using modern tools of macromolecular design. We believe that this strategy affords functionalized PVA physical hydrogels which meet the demands of modern nanobiotechnology and have a potential to become an indispensable tool in the design of biomaterials.

Inertness and the indiscriminate use of synthetic polymers leading to increased land and water pollution are of great concern. Plastic is the most useful synthetic polymer, employed in wide range of applications viz. the packaging industries, agriculture, household practices, etc. Unpredicted use of synthetic polymers is leading towards the accumulation of increased solid waste in the natural environment. This affects the natural system and creates various environmental hazards. Plastics are seen as an environmental threat because they are difficult to degrade. This review describes the occurrence and distribution of microbes that are involved in the degradation of both natural and synthetic polymers. Much interest is generated by the degradation of existing plastics using microorganisms. It seems that biological agents and their metabolic enzymes can be exploited as a potent tool for polymer degradation. Bacterial and fungal species are the most abundant biological agents found in nature and have distinct degradation abilities for natural and synthetic polymers.

“…VM15C, P. vesicularis XL, P. vesicularis XL, and P. vesicularis PD. More recent studies have shown that isotactic blocks in PVA molecule are more readily biodegraded than those having an atactic structure (174,175). The biological oxygen demand for degradation of a 0.1% PVA solution is approximately 5 ppm (170).…”
