“…This is from the ethical standpoint and the need to prevent increase in food prices and disrupting global food supplies ( Koller and Braunegg, 2018 ). Therefore, there has been efforts by scientists to valorize waste streams as carbon sources for the production of PHAs, which aligns with the biorefinery concept ( Al-Battashi et al, 2019 ). Lignocellulosic biomass is inedible and has demonstrated great potential as a carbon source for PHA production ( Matsumoto et al, 2011b ; Nduko et al, 2012b ; Bhatia et al, 2019 ; Li and Wilkins, 2020 ).…”

Polyhydroxyalkanoates (PHAs) are naturally occurring biopolymers produced by microorganisms. PHAs have become attractive research biomaterials in the past few decades owing to their extensive potential industrial applications, especially as sustainable alternatives to the fossil fuel feedstock-derived products such as plastics. Among the biopolymers are the bioplastics and oligomers produced from the fermentation of renewable plant biomass. Bioplastics are intracellularly accumulated by microorganisms as carbon and energy reserves. The bioplastics, however, can also be produced through a biochemistry process that combines fermentative secretory production of monomers and/or oligomers and chemical synthesis to generate a repertoire of biopolymers. PHAs are particularly biodegradable and biocompatible, making them a part of today’s commercial polymer industry. Their physicochemical properties that are similar to those of petrochemical-based plastics render them potential renewable plastic replacements. The design of efficient tractable processes using renewable biomass holds key to enhance their usage and adoption. In 2008, a lactate-polymerizing enzyme was developed to create new category of polyester, lactic acid (LA)–based polymer and related polymers. This review aims to introduce different strategies including metabolic and enzyme engineering to produce LA-based biopolymers and related oligomers that can act as precursors for catalytic synthesis of polylactic acid. As the cost of PHA production is prohibitive, the review emphasizes attempts to use the inexpensive plant biomass as substrates for LA-based polymer and oligomer production. Future prospects and challenges in LA-based polymer and oligomer production are also highlighted.

“…Rodriguez-Perez et al stated that waste-containing sugar and/or fatty acids may be the best feedstocks for PHA production [ 78 ]. Based on Chee et al, the PHA yield produced using fatty acid substrates and sugar substrate as feedstocks were around 0.6–0.8 g/g and 0.3–0.4 g/g, respectively [ 79 ].…”

Polyhydroxyalkanoates (PHA) are biodegradable polymers that are considered able to replace synthetic plastic because their biochemical characteristics are in some cases the same as other biodegradable polymers. However, due to the disadvantages of costly and non-renewable carbon sources, the production of PHA has been lower in the industrial sector against conventional plastics. At the same time, first-generation sugar-based cultivated feedstocks as substrates for PHA production threatens food security and considerably require other resources such as land and energy. Therefore, attempts have been made in pursuit of suitable sustainable and affordable sources of carbon to reduce production costs. Thus, in this review, we highlight utilising waste lignocellulosic feedstocks (LF) as a renewable and inexpensive carbon source to produce PHA. These waste feedstocks, second-generation plant lignocellulosic biomass, such as maize stoves, dedicated energy crops, rice straws, wood chips, are commonly available renewable biomass sources with a steady supply of about 150 billion tonnes per year of global yield. The generation of PHA from lignocellulose is still in its infancy, hence more screening of lignocellulosic materials and improvements in downstream processing and substrate pre-treatment are needed in the future to further advance the biopolymer sector.

“…3,4 The most abundant type of biomass is lignocellulosic biomass, which can be obtained from dedicated crops or residues or waste from agricultural or forestry activities as well as food waste, 5 the latter being far more preferable to avoid competition with food products. [6][7][8] In addition, the exploitation of such lignocellulosic waste could represent an opportunity for the development of economies in rural economies where agricultural activities prevail.…”
