Structural insights, biocatalytic characteristics, and application prospects of lignin-modifying enzymes for sustainable biotechnology-A review. Int J Biol Macromol 2023:124968. [PMID: 37217044 DOI: 10.1016/j.ijbiomac.2023.124968] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/04/2023] [Revised: 04/22/2023] [Accepted: 05/17/2023] [Indexed: 05/24/2023]
Abstract
Lignin modifying enzymes (LMEs) have gained widespread recognition in depolymerization of lignin polymers by oxidative cleavage. LMEs are a robust class of biocatalysts that include lignin peroxidase (LiP), manganese peroxidase (MnP), versatile peroxidase (VP), laccase (LAC), and dye-decolorizing peroxidase (DyP). Members of the LMEs family act on phenolic, non-phenolic substrates and have been widely researched for valorization of lignin, oxidative cleavage of xenobiotics and phenolics. LMEs implementation in the biotechnological and industrial sectors has sparked significant attention, although its potential future applications remain underexploited. To understand the mechanism of LMEs in sustainable pollution mitigation, several studies have been undertaken to assess the feasibility of LMEs in correlating to diverse pollutants for binding and intermolecular interactions at the molecular level. However, further investigation is required to fully comprehend the underlying mechanism. In this review we presented the key structural and functional features of LMEs, including the computational aspects, as well as the advanced applications in biotechnology and industrial research. Furthermore, concluding remarks and a look ahead, the use of LMEs coupled with computational frameworks, built upon artificial intelligence (AI) and machine learning (ML), has been emphasized as a recent milestone in environmental research.

Abstract
Los hidrocarburos policíclicos aromáticos (HPAs) son compuestos tóxicos que no se degradan fácilmente bajo condiciones naturales tales como fenómenos físicos (fotooxidación, volatilización), químicos (intercambio iónico, complejación, transformación) y biológicos (degradación por microorganismos autóctonos) que además, dependen de la temperatura, humedad y niveles de oxígeno. El objetivo del presente trabajo fue aislar, identificar y caracterizar fenotípicamente hongos hidrocarbono clásticos de ambientes extremos que sean capaces de tolerar HPAs, tales como Trametes coccinea IDEA, que se aisló del Lago de asfalto natural de Guanoco en Venezuela. A fin de estudiar su tolerancia a los HPAs, el hongo se expuso a diferentes concentraciones de naftaleno, fenantreno y pireno (0, 2.5, 25, 50, 100, 200, 400, 800 y 1600 mg/L). Posteriormente, en ensayo en medio de cultivo líquido, se procedió a estudiar el efecto de los HPAs sobre la actividad de enzimas del sistema enzimático de degradación de lignina (SEDL), así como sobre la posible variación en los niveles de toxicidad empleando Lactuca sativa como bioindicador. Los resultados mostraron una mayor tolerancia al pireno, seguido por el naftaleno y fenantreno. Se observó una fuerte inducción de la actividad lacasa en presencia de naftaleno (167.96 U/mgP) y pireno (124.89 U/mgP) con respecto al control, mientras que con fenantreno se obtuvo una baja actividad (88.67 U / mgP). De manera interesante, se evidenció una generación de sub-productos más tóxicos cuando el naftaleno y el fenantreno fueron biotratados por el hongo, mientras que el nivel de toxicidad del pireno disminuyó significativamente. T. coccinea IDEA tiene un alto potencial para ser utilizado en estrategias de biorremediación de hidrocarburos, las cuales deben ser monitoreadas mediante análisis ecotoxicológicos para detectar posibles variaciones de toxicidad de los productos parcialmente biotransformados.

Ligninolytic Enzyme Production and Decolorization Capacity of Synthetic Dyes by Saprotrophic White Rot, Brown Rot, and Litter Decomposing Basidiomycetes. J Fungi (Basel) 2020; 6:jof6040301. [PMID: 33228232 PMCID: PMC7711621 DOI: 10.3390/jof6040301] [Citation(s) in RCA: 17] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/27/2020] [Revised: 11/13/2020] [Accepted: 11/17/2020] [Indexed: 01/18/2023] Open
Abstract
An extensive screening of saprotrophic Basidiomycetes causing white rot (WR), brown rot (BR), or litter decomposition (LD) for the production of laccase and Mn-peroxidase (MnP) and decolorization of the synthetic dyes Orange G and Remazol Brilliant Blue R (RBBR) was performed. The study considered in total 150 strains belonging to 77 species. The aim of this work was to compare the decolorization and ligninolytic capacity among different ecophysiological and taxonomic groups of Basidiomycetes. WR strains decolorized both dyes most efficiently; high decolorization capacity was also found in some LD fungi. The enzyme production was recorded in all three ecophysiology groups, but to a different extent. All WR and LD fungi produced laccase, and the majority of them also produced MnP. The strains belonging to BR lacked decolorization capabilities. None of them produced MnP and the production of laccase was either very low or absent. The most efficient decolorization of both dyes and the highest laccase production was found among the members of the orders Polyporales and Agaricales. The strains with high MnP activity occurred across almost all fungal orders (Polyporales, Agaricales, Hymenochaetales, and Russulales). Synthetic dye decolorization by fungal strains was clearly related to their production of ligninolytic enzymes and both properties were determined by the interaction of their ecophysiology and taxonomy, with a more relevant role of ecophysiology. Our screening revealed 12 strains with high decolorization capacity (9 WR and 3 LD), which could be promising for further biotechnological utilization.

Abstract
The main organochlorinated compounds used on agricultural crops are often recalcitrant, affecting nontarget organisms and contaminating rivers or groundwater. Diuron (N-(3,4-dichlorophenyl)-N',N'-dimethylurea) is a chlorinated herbicide widely used in sugarcane plantations. Here, we evaluated the ability of 13 basidiomycete strains of growing in a contaminated culture medium and degrading the xenobiotic. Dissipation rates in culture medium with initial 25 mg/L of diuron ranged from 7.3 to 96.8%, being Pluteus cubensis SXS 320 the most efficient strain, leaving no detectable residues after diuron metabolism. Pycnoporus sanguineus MCA 16 removed 56% of diuron after 40 days of cultivation, producing three metabolites more polar than parental herbicide, two of them identified as being DCPU and DCPMU. Despite of the strong inductive effect of diuron upon laccase synthesis and secretion, the application of crude enzymatic extracts of P. sanguineus did not catalyzed the breakdown of the herbicide in vitro, indicating that diuron biodegradation was not related to this oxidative enzyme.

Abstract
BACKGROUND Atrazine is one of the most widespread chlorinated herbicides, leaving large bulks in soils and groundwater. The biodegradation of atrazine by bacteria is well described, but many aspects of the fungal metabolism of this compound remain unclear. Thus, we investigated the toxicity and degradation of atrazine by 13 rainforest basidiomycete strains. RESULTS In liquid medium, Pluteus cubensis SXS320, Gloelophyllum striatum MCA7, and Agaricales MCA17 removed 30, 37, and 38%, respectively, of initial 25 mg L- 1 of the herbicide within 20 days. Deficiency of nitrogen drove atrazine degradation by Pluteus cubensis SXS320; this strain removed 30% of atrazine within 20 days in a culture medium with 2.5 mM of N, raising three metabolites; in a medium with 25 mM of N, only 21% of initial atrazine were removed after 40 days, and two metabolites appeared in culture extracts. This is the first report of such different outcomes linked to nitrogen availability during the biodegradation of atrazine by basidiomycetes. The herbicide also induced synthesis and secretion of extracellular laccases by Datronia caperata MCA5, Pycnoporus sanguineus MCA16, and Polyporus tenuiculus MCA11. Laccase levels produced by of P. tenuiculus MCA11 were 13.3-fold superior in the contaminated medium than in control; the possible role of this enzyme on atrazine biodegradation was evaluated, considering the strong induction and the removal of 13.9% of the herbicide in vivo. Although 88% of initial laccase activity remained after 6 h, no evidence of in vitro degradation was observed, even though ABTS was present as mediator. CONCLUSIONS This study revealed a high potential for atrazine biodegradation among tropical basidiomycete strains. Further investigations, focusing on less explored ligninolytic enzymes and cell-bound mechanisms, could enlighten key aspects of the atrazine fungal metabolism and the role of the nitrogen in the process.

Abstract
Temperature is an important environmental factor that can greatly influence the cultivation of Auricularia cornea. In this study, lignin peroxidase, laccase, manganese peroxidase, and cellulose in A. cornea fruiting bodies were tested under five different temperatures (20 °C, 25 °C, 30 °C, 35 °C, and 40 °C) in three different culture periods (10 days, 20 days and 30 days). In addition, the V4 region of bacterial 16S rRNA genes in the substrate of A. cornea cultivated for 30 days at different temperatures were sequenced using next-generation sequencing technology to explore the structure and diversity of bacterial communities in the substrate. Temperature and culture days had a significant effect on the activities of the four enzymes, and changes in activity were not synchronized with changes in temperature and culture days. Overall, we obtained 487,694 sequences from 15 samples and assigned them to 16 bacterial phyla. Bacterial community composition and structure in the substrate changed when the temperature was above 35 °C. The relative abundances of some bacteria were significantly affected by temperature. A total of 35 genera at five temperatures in the substrate were correlated, and 41 functional pathways were predicted in the study. Bacterial genes associated with the membrane transport pathway had the highest average abundance (16.16%), and this increased at 35 °C and 40 °C. Generally, different temperatures had impacts on the physiological activity of A. cornea and the bacterial community in the substrate; therefore, the data presented herein should facilitate cultivation of A. cornea.

Abstract
Soda saline-alkaline lands are significantly harmful to agriculture; thus, effective strategies to remediate such soil are urgently needed. Multiple negative factors exist in the community structure of saline-alkaline fields, among which the lack of fungal species diversity remains the most prominent problem. The haloalkaliphilic fungi are a unique group of extremophiles that grow optimally under conditions of extreme salinity and alkalinity; these fungi, which buffer salinity and alkalinity by absorbing and/or constraining salt ions, produce organic acids and/or macromolecules, secrete macromolecules such as cellulose degradation enzymes, and provide biomass that is beneficial for soil health. Considering that haloalkaliphilic fungi are a valuable genetic resource of resistance and degradation genes, these fungi are expected to be applied in biotechnology. Aspergillus glaucus exhibits high resistance to a variety of stressors and the ability to degrade crop straw; and it is a practical genetic tool that can be used to identify and validate genes involved in abiotic stress resistance and cellulose decomposition genes. This review will focus on the following aspects: isolation of extreme haloalkaliphilic fungi, fungal genes involved in salt and alkalinity resistance, macromolecule degrading enzymes, applications for genetic improvement of haloalkaliphilic fungi, and application of haloalkaliphilic fungi in saline-alkali soil mycoremediation.

Abstract
A moderate halophile and thermotolerant fungal strain was isolated from a sugarcane bagasse fermentation in the presence of 2 M NaCl that was set in the laboratory. This strain was identified by polyphasic criteria as Aspergillus caesiellus. The fungus showed an optimal growth rate in media containing 1 M NaCl at 28°C and could grow in media added with up to 2 M NaCl. This strain was able to grow at 37 and 42°C, with or without NaCl. A. caesiellus H1 produced cellulases, xylanases, manganese peroxidase (MnP) and esterases. No laccase activity was detected in the conditions we tested. The cellulase activity was thermostable, halostable, and no differential expression of cellulases was observed in media with different salt concentrations. However, differential band patterns for cellulase and xylanase activities were detected in zymograms when the fungus was grown in different lignocellulosic substrates such as wheat straw, maize stover, agave fibres, sugarcane bagasse and sawdust. Optimal temperature and pH were similar to other cellulases previously described. These results support the potential of this fungus to degrade lignocellulosic materials and its possible use in biotechnological applications.

Abstract
In the present investigation, four species of white rot fungi (Pleurotus), that is, P. flabellatus, P. florida, P. ostreatus and P. sajor-caju were used for decolorization of direct blue 14 (DB14). Among all four species of Pleurotus, P. flabellatus showed the fastest decolorization in petri plates on different concentration, that is, 200 mg/L, 400 mg/L, and 600 mg/L. All these four species were also evaluated for extracellular ligninolytic enzymes (laccase and manganese peroxidase) production and it was observed that the twelve days old culture of P. flabellatus showed the maximum enzymatic activity, that is, 915.7 U/mL and 769.2 U/mL of laccase and manganese peroxidase, respectively. Other three Pleurotus species took more time for dye decolorization and exhibited less enzymatic activities. The rate of decolorization of DB14 dye solution (20 mg/L) by crude enzymes isolated from P. flabellatus was very fast, and it was observed that up to 90.39% dye solution was decolorized in 6 hrs of incubation.
