“…Many recent reviews have attempted to capture the evolving field of microbial degradation of lignin. [13][14][15][16][17][18] However, most of these review articles lack discussions of either the industrial applications of microbial degradation of lignin, the inter-species variation in the efficacy of lignin biodegradation by microbes, the nonenzymatic pathways of microbial lignin degradation, or all of these (Table 1). Without reviews and studies that discuss these aspects of microbial lignin biodegradation together, it will be difficult to make this process translatable for industrial settings.…”

“…Microbes, including fungi and bacteria, offer a number of environment‐friendly and efficient approaches to degrade lignin, many of which may have commercial potential. Many recent reviews have attempted to capture the evolving field of microbial degradation of lignin 13–18 .

Lignin is an abundant plant‐based biopolymer that has found applications in a variety of industries from construction to bioethanol production. This recalcitrant branched polymer is naturally degraded by many different species of microorganisms, including fungi and bacteria. These microbial lignin degradation mechanisms provide a host of possibilities to overcome the challenges of using harmful chemicals to degrade lignin biowaste in many industries. The classes and mechanisms of different microbial lignin degradation options available in nature form the primary focus of the present review. This review first discusses the chemical building blocks of lignin and the industrial sources and applications of this multifaceted polymer. The review further places emphasis on the degradation of lignin by natural means, discussing in detail the lignin degradation activities of various fungal and bacterial species. The lignin‐degrading enzymes produced by various microbial species, specifically white‐rot fungi, brown‐rot fungi, and bacteria, are described. In the end, possible directions for future lignin biodegradation applications and research investigations have been provided.

“…The organisms responsible for the release of these hydrolases, or other organisms in proximity to these hydrolytic organisms, can then utilize the liberated organic materials for cellular metabolism, sense their local environment or provide chemical protection. There are several reviews covering various interpretations of whole cell microbial [15][16][17][18][19][20][21][22][23][24][25] and isolated enzyme [26][27][28][29][30] polymer biodegradation mechanisms. We chose to review the new advances in the most recent biodegradation literature with an emphasis on recent trends and directions in the field using condensation polymers (specifically, polyesters and polyurethanes) and isolated hydrolases.…”

Natural and synthetic polymers represent a challenging source of raw materials to harvest and control in our environment. All polymeric materials eventually deteriorate and degrade over time due to changes in the inter-or intramolecular bonding resulting from biological and/or environmental exposure. Microorganisms use a combination of cellular hydrolytic and oxidative chemical processes to release carbon sources from polymers. Specifically, polyesters and polyurethanes are susceptible to hydrolysis by catabolic enzymes released by fungi, bacteria and archaea in the environment, and these polymer classes make up 35% of global polymer production. This review focuses on the activity of lipases, cutinases, esterases and proteases with polyesters and polyurethanes reported in articles from 2018 or later as well as new advances and key trends in both fundamental and applied biodegradation research efforts.

“…Moreover, the efficient hydrolysis of cellulose either for pulp or biofuel production is contingent upon degradation of lignin. Conventional methods of dissolving lignin in wood involve the use of chemicals and bleaching agents (LIEW et al, 2011;AYERONFE et al, 2018). These processes do not only require high inputs of energy but also produce highly toxic effluents which are not environmental friendly (SUMATHI;HUNG, 2006).…”

The application of ligninolytic bacteria and enzymes is a green pre-treatment alternative in the production of paper and biofuel from oil palm residues. In this study we investigated the ability of Lysinibacillus pakistanensis isolated from termite gut in degrading the lignin component of oil palm residues. The residues were biotreated with the bacterial strain in an aerated submerged fermentation system for 7 days at 30 , pH 7 and compared with untreated control. Enzyme activities were determined using specific substrates. Peak lignin peroxidase (377.6 U/L), manganese peroxidase (218.19 U/L), and laccase (405.4 U/L) activity were recorded after 4,4, and 5 days of incubation respectively, using oil palm leaf as substrates. Lignin loss of 4.5%, 5.7% and 6.6% in oil palm leaf, oil palm trunk and empty fruit bunch respectively was achieved after treatment with the microorganism. SEM images revealed structural changes in the cell wall of the residues. Pre-treatment with this bacterial strain has promising prospects of improving the efficiency of the pulping process in an environmentally safe manner.
