“…Agroindustrial residues provide substantial, economic, and renewable natural biological resources for large-scale, profitable biofuel production and types of chemical products including industrial biocatalysts (Birhanli and Yesilada 2013;Ikubar et al 2018;Unuofin et al 2019b;Agrawal and Verma 2020). Due to these advantages, more studies have focused on the effects of various lignocellulosic materials on laccase secretion of fungi or bacteria, especially white-rot fungi, in recent years (Simonic et al 2010;Singh et al 2010;Srinivasan et al 2019;Thamvithayakorn et al 2019;Unuofin et al 2019b;Atilano-Camino et al 2020;Shanmugam et al 2020). Thus, sorghum straw, Populus beijingensis, Toona sinensis, and Salix babylonica were used to grow white-rot fungi producing laccase.…”

The capacity of novel isolated white-rot fungi secreting laccase was evaluated for various kinds of lignocellulosic biomass in submerged fermentation. The laccase secreted by Neofomitella fumosipora Han 386 and Pleurotus pulmonarius Han 527 was significantly faster than that by Coriolopsis trogii Han 751 and Coriolopsis sanguinaria An 282. Maximum laccase from N. fumosipora Han 386 on the four kinds of lignocellulosic biomass tested appeared on the first day. This phenomenon indicated that N. fumosipora Han 386 secreted laccase rapidly compared with other tested strains in this study and showed the superiority in the rate of secreting laccase. Based on the maximum laccase activity, the ability of secreting laccase of C. sanguinaria An 282 was superior to other tested novel isolated strains. On the whole, N. fumosipora Han 386 and P. pulmonarius Han 527 preferred Toona sinensis to produce laccase, C. trogii Han 751 preferred to produce laccase on Populus beijingensis, and C. sanguinaria An 282 grown on Sorghum straw was more suitable for secreting laccase. The results will be helpful for developing bioprocesses using various kinds of lignocellulosic biomass for lignocellulolytic enzyme production and enlarging the number of laccase producing strains for industrial application.

“…Agro-and forestry residues, e.g., sugarcane bagasse, grasses, corncob, cottonseed hull, bamboos, etc., are composed of lignin, cellulose, and hemicellulose (Pinheiro et al 2020). The production of enzymes via agro-and forestry residues has attracted widespread attention, especially laccase, due to the wide existence and low price of agro-and forestry residues (Lizardi-Jimenez et al 2019;Palazzolo et al 2019;Srinivasan et al 2019;Thamvithayakorn et al 2019;Agrawal and Verma 2020;Atilano-Camino et al 2020;Pinheiro et al 2020;Xu et al 2020).…”

“…Laccase (EC 1.10.3.2), one of most important ligninolytic enzymes, alone or together with other ligninolytic enzymes, including lignin peroxidase (Lip) and manganese peroxidase (Mnp), belongs to a family of copper oxidases and is distributed in higher plants, cyanobacteria, bacteria, insects, and fungi (Yang et al 2017;Srinivasan et al 2019). Laccase has the ability of catalyzing a wide range of reactions, including organic and inorganic substrates (Sharma et al 2007;Jaya Mary et al 2018).…”

Laccase activity from Pleurotus ostreatus and Flammulina velutipes strains was investigated with various agro- and forestry residues by solid-state fermentation. Different species or strains belonging to the same species had the unique capacity of secreting laccase on solid-state fermentation with various agro- and forestry residues. Overall, the capacity of secreting laccase for P. ostreatus strains was superior to F. velutipes strains due to the value of maximum activity on various agro- and forestry residues, except on the stalk of straw. Compared with Populus beijingensis, corncob, and stalk of straw, the presence of cottonseed hull was helpful to improve laccase activity for P. ostreatus strains because the maximum laccase activity from cottonseed hull was higher than that from the other three agro- and forestry residues. The presence of stalk of straw was more helpful to improve laccase activity for F. velutipes strains because of the maximum laccase activity from stalk of straw was higher that from Populus beijingensis, corncob, and cottonseed hull. These results indicated the importance of selecting suitable agro- and forestry residues for fungi producing laccase. These findings contributed to the selection of suitable strains to obtain an integrated application of low-cost laccase in the factory.

“…Removal of these compounds from the contaminated water is necessary due to their low biodegradability (Pera-Titus et al 2004) and toxicity (Liu et al 2012) as well as the pressure to comply with stringent standards against their disposal (Karam and Nicell 1997). Laccases have been extensively investigated as potential candidates for the remediation of several pollutants (Srinivasan et al 2019(Srinivasan et al , 2020. Laccases are multi-copper oxidases which have been gaining a lot of attention mainly due to their ability to catalyse the oxidation of a broad range of substrates without the aid of any cofactors (Upadhyay et al 2016).…”

Enzymatic treatment of phenolic pollutants by a small laccase immobilized on APTES-functionalised magnetic nanoparticles

In this study, we have successfully synthesized magnetic nanoparticles (MNPs), functionalised them by silanization and used them for the covalent immobilization of a recombinant small laccase (rSLAC) from Streptomyces coelicolor. The immobilized recombinant laccase (MNP-rSLAC) was subsequently used for the treatment of phenol, 4-chlorophenol (4-CP) and 4-fluorophenol (4-FP). The enzyme completely degraded 80 µg/mL of the selected phenolic compounds within 2 h in the presence of a natural mediator, acetosyringone. The MNP-rSLAC retained > 73% of initial activity (2,6-dimethoxyphenol as substrate) after 10 catalytic cycles and could be easily recovered from the reaction mixture by the application of magnetic field. Furthermore, immobilised rSLAC exhibited better storage stability than its free counterpart. The Michaelis constant (K m ) value for the immobilised rSLAC was higher than free rSLAC, however the maximum velocity (V max ) of the immobilised SLAC was similar to that of the free rSLAC. Growth inhibition studies using Escherichia coli showed that rSLACmediated treatment of phenolic compounds reduced the toxicity of phenol, 4-CP and 4-FP by 90, 60 and 55%, respectively. Interestingly, the presence of selected metal ions (Co 2+ , Cu 2+ , Mn 2+ ) greatly enhanced the catalytic activity of rSLAC and MNP-rSLAC. This study indicates that immobilized small laccase (MNP-rSLAC) has potential for treating wastewater contaminated with phenolic compounds.
