With the increasing concerns regarding climate, energy, and plastic crises, bio-based production of biodegradable polymers has become a dire necessity. Significant progress has been made in biotechnology for the production of biodegradable polymers from renewable resources to achieve the goal of zero plastic waste and a net-zero carbon bioeconomy. In this review, an overview of polyhydroxyalkanoate (PHA) production from lignocellulosic biomass (LCB) was presented. Having established LCB-based biorefinery with proper pretreatment techniques, various PHAs could be produced from LCB-derived sugars, hydrolysates, and/or aromatic mixtures employing microorganisms. This provides a clue for addressing the current environmental crises because "biodegradable polymers" could be produced from one of the most abundant resources that are renewable and sustainable in a "carbon-neutral process". Furthermore, the potential future of LCB-to-non-natural PHA production was discussed with particular reference to non-natural PHA biosynthesis methods and LCB-derived aromatic mixture biofunnelling systems.

The efficient conversion of xylose is a short board of cask effect to lignocellulosic biorefining, by markedly affecting the total economic and environmental benefits. Based on a comprehensive analysis of the current commercial status of traditional xylose utilization and industrial technology development, this review outlines new technological avenues for the efficient utilization of xylose from lignocellulosic biomass, focusing on super prebiotic xylo-oligosaccharides and multifunctional platform compound xylonic acid. Firstly, the traditional products that can be derived from lignocellulosic xylose, including xylitol (447.

Lignocellulosic waste, like corn stover (CS), is widely produced and serves as a key feedstock for biofuels and biochemicals. Semi-continuous subcritical water hydrolysis (SWH) is an eco-friendly method that breaks down cellulose and hemicellulose bonds. To boost fermentable sugar (FS) yields, steam explosion (SE) pretreatment was tested on CS, achieving a cellulose content of 74.

The aim of fungal treatment of organic matter for ruminants is the improvement of its degradability. So far, such treatment appears to be time-consuming and improvement has been modest. In previous work, we observed within three white rot species that there is modest () or low ( and ) variation in fiber degradation in wheat straw during seven weeks of incubation.

The present study reports the ability of a fungal isolate DY1, obtained from rotten wood, to degrade alkali lignin (AL) and lignocelluloses in an efficient manner. The efficiency of degradation was monitored by measuring the percentage of decolorization and utilizing GC-MS for identifying degradation products at different time intervals (10, 20, 30, and 40 days). The optimal degradation of alkali lignin (AL) was achieved at 0.

Lignin, with its complex, high-molecular-weight aromatic polymer structure and stable ether or ester bonds, greatly impedes the efficient degradation of lignocellulosic waste. Bacterial laccases have gained attention for their potential in lignocellulosic waste degradation due to their resilience in extreme conditions and ability to be produced in large quantities. In this study, a novel laccase from Geobacillus thermocatenulatus M17 was identified and expressed in E.
