“…White-rot, brown-rot and softrot fungi are used for degradation of lignin and hemicelluloses present in LCB (Chen et al, 2010). However, mostly whiterot fungi are involved in biological pretreatment due to high sugar yield associated with enzymatic saccharification (Yesilada et al, 2018). Some white-rot fungi can simultaneously degrade lignin and polysaccharides, resulting in the loss of carbohydrates, while other white-rot fungi can selectively degrade lignin.…”

Lignocellulosic biomass (LCB) is the most abundantly available bioresource amounting to about a global yield of up to 1. 3 billion tons per year. The hydrolysis of LCB results in the release of various reducing sugars which are highly valued in the production of biofuels such as bioethanol and biogas, various organic acids, phenols, and aldehydes. The majority of LCB is composed of biological polymers such as cellulose, hemicellulose, and lignin, which are strongly associated with each other by covalent and hydrogen bonds thus forming a highly recalcitrant structure. The presence of lignin renders the bio-polymeric structure highly resistant to solubilization thereby inhibiting the hydrolysis of cellulose and hemicellulose which presents a significant challenge for the isolation of the respective bio-polymeric components. This has led to extensive research in the development of various pretreatment techniques utilizing various physical, chemical, physicochemical, and biological approaches which are specifically tailored toward the source biomaterial and its application. The objective of this review is to discuss the various pretreatment strategies currently in use and provide an overview of their utilization for the isolation of high-value bio-polymeric components. The article further discusses the advantages and disadvantages of the various pretreatment methodologies as well as addresses the role of various key factors that are likely to have a significant impact on the pretreatment and digestibility of LCB.

“…Laccase can catalyze the oxidation of a variety of aromatic compounds (preferably phenolic compounds) [1,2] and has been widely employed for delignification, plant fiber derivatization, textile dye or stain bleaching, and contaminated water or soil detoxification [3][4][5][6]. However, the industrial applications of laccase are still seriously limited owing to their poor stability and high cost [7].…”

In this work, laccase from Trametes versicolor pretreated with copper ion solution was entrapped in copper alginate beads. The presence of laccase in copper alginate beads was verified by Fourier transform infrared (FTIR) spectroscopy. The alginate concentration used was optimized based on the specific activity and immobilization yield. After entrapment, laccase presents perfect pH stability and thermal stability with 2,2′-azinobis-(3-ethylbenzthiazoline-6-sulphonate) (ABTS) as the substrate. Moreover, laccase in copper alginate beads exhibits good reusability during continuous batch operation for removing 2,4-dichlorophenol. More importantly, owing to the coupled effect of copper ion activation and copper alginate entrapment, the entrapped laccase shows a 3.0-fold and a 2.4-fold increase in specific activity and 2,4-DCP degradation rate compared with that of free laccase, respectively.

Over the last decades, the presence of highly organic pollutants has increased and become an environmental problem that affects all forms of life. To solve or reduce this problem, multiple strategies have been proposed for the elimination and degradation of organic compounds in aqueous media. This review aims to revise and critically discuss the most recent advances in polymer supports to be used for the adsorption and degradation of organic pollutants. However, the greatest challenge with respect to this issue is the industrial scale‐up of bioremediation processes that allow the removal and degradation of compounds in a continuous and large‐scale manner. © 2019 Society of Chemical Industry
