“…This enzyme uses sucrose as a substrate and breaks the bond between glucose and fructose to generate dextran and fructose. Dextran is one of the earliest EPS industrially produced (Selvi et al, 2019), formed by consecutive glucose longchained bonded molecules (Heerden et al, 2014;Rani et al, 2017;Oropeza-De la Rosa et al, 2019). However, dextran produced by Leuconostoc spp.…”

“…In vitro PHA production employing thermophilic bacteria-derived acetyl-CoA synthetase (ACS) and CoA transferase (CT) has been reported. These studies demonstrated that thermostable ACS and CT enzymes have the ability to create more PHB than nonthermostable ACS and CT enzymes. , In another study, poly(lactate- co -3-hydroxybutyrate) [P(LA- co -3HB]) copolymer in recombinant Escherichia coli was produced using d -lactyl-coenzymeA (LA-CoA) and polyhydroxyalkanoate synthase (PhaC1 Ps STQK). The authors reported that the copolymerization process was highly dependent on the LA-CoA concentration and the vigor of the resultant polymeric products .…”

The runaway production and consumption of oilbased plastics are key drivers of global warming and the increased carbon footprint. Besides, most of this plastic debris ends up in the oceans and constitutes about 80% of all marine debris. This pollution problem calls for a seismic shift to eco-friendly plastics and marine biodegradable ones. Unlike other biobased polymers, polyhydroxyalkanoates (PHAs) take pride in their degradation in soil and marine environments. This intriguing marine biodegradation property of PHAs sets it apart as the best choice to curb microplastics, particularly in marine ecosystems. PHAs have also grown in popularity due to other quintessential properties such as biocompatibility, structural variety, and similarity to conventional plastics in terms of physical properties. PHAs are being widely researched for various applications, including packaging, medical, energy, and agriculture. This perspective comprehensively focuses on the state-of-art production and applications of PHA plastics as well as the practical recycling strategies for postconsumer PHAs. The innovative "next generation industrial biotechnology" (NGIB) is well covered in this perspective. Moreover, the nexus between end-of-life strategies and life cycle assessment (LCA) of PHAs waste is elucidated to understand its impact on the environment thoroughly.

“…Dextran is an exopolysaccharide with mostly α-1,6 glycosidic bonds (though smaller numbers of branching α-1,3, α-1,2 and α-1,4 bonds are present) [ 25 , 26 ]. Dextran utilization is widely recognized in food [ 27 , 28 , 29 ], cosmetic [ 26 ], and medicine [ 25 ]. Louis Pasteur first discovered dextran in 1861 from a viscous fermentation of wine [ 30 ], and later identified it via the chemical analysis of the product responsible for sucrose sugar syrup gelation [ 31 ].…”

Plastics have found widespread use in the fields of cosmetic, engineering, and medical sciences due to their wide-ranging mechanical and physical properties, as well as suitability in biomedical applications. However, in the light of the environmental cost of further upscaling current methods of synthesizing many plastics, work has recently focused on the manufacture of these polymers using biological methods (often bacterial fermentation), which brings with them the advantages of both low temperature synthesis and a reduced reliance on potentially toxic and non-eco-friendly compounds. This can be seen as a boon in the biomaterials industry, where there is a need for highly bespoke, biocompatible, processable polymers with unique biological properties, for the regeneration and replacement of a large number of tissue types, following disease. However, barriers still remain to the mass-production of some of these polymers, necessitating new research. This review attempts a critical analysis of the contemporary literature concerning the use of a number of bacteria-derived polymers in the context of biomedical applications, including the biosynthetic pathways and organisms involved, as well as the challenges surrounding their mass production. This review will also consider the unique properties of these bacteria-derived polymers, contributing to bioactivity, including antibacterial properties, oxygen permittivity, and properties pertaining to cell adhesion, proliferation, and differentiation. Finally, the review will select notable examples in literature to indicate future directions, should the aforementioned barriers be addressed, as well as improvements to current bacterial fermentation methods that could help to address these barriers.
