“…Vanillin, 4‐hydroxybenzaldehyde, and syringaldehyde are typical representatives of the G, H, and S group in lignin, respectively, and these inhibitors generated from pretreatment would precipitate the enzymes, hampering hydrolysis and fermentation . Several Trichoderma species have alternative enzyme systems commonly seen in other organisms, such as multicooper laccase peroxidases and dioxygenase, which make it possible to degrade phenolics.…”

Agricultural straw is abundant worldwide, but efficient production of lactic acid from straw is still challenging. In this paper, Trichoderma viride R16 was cultivated using corncob as the substrate in a fed-batch process, after which the enzymes from T. viride R16 broth were analyzed through protein mass J Liu et al.Spotlight: Dioxygenase from Trichoderma viride R16 enhances the lactic acid production using pretreated corncob spectrometry and used for lactic acid production. Dioxygenase activity was found in the T. viride R16 enzymes, and 0.2 g L -1 phenolics (vanillin, 4-hydroxybenzaldehyde, syringaldehyde) was degraded during enzyme production. Lactic acid production and yield from NH 3 -H 2 O 2 pretreated and washed corncob were increased by more than 24% and total phenolics was significantly lower using T. viride R16 enzymes compared with commercial enzymes in batch and fed-batch fermentation. These characteristics of T. viride R16 support industrial applications with efficient in situ detoxification of phenolic inhibitors without adding an extra step during lactic acid production from pretreated agricultural straw using simultaneous saccharification and fermentation.

“…It is worth to point out that, due to real possibilities to obtain valuable by‐products from lignin treatments using modern industrial processes, most of techno‐economic works reported in literature about lignin valorization have been aimed to assess new delignification techniques or ways to obtain especial chemical compounds . This seems to be the main reason by which similar studies focused on the use of lignin as fuel are very scarce, being almost exclusively linked to the pulp and paper industry .…”

Looking for alternatives to promote the diversification of the Brazilian energy grid through the utilization of renewable fuels, this forecasting study evaluates the potential to generate thermal energy from lignins extracted of several crops in the period 2015–2021. The estimates were carried out taking into account two biomass particle size distributions (ranged between 105–500 µm and 1000–2000 µm) and two extraction methods (Klason and Willstatter) to assess the lignin yields obtained from five well‐known Brazilian crops. Results revealed that lignins obtained from the sugarcane bagasse, wood chips, and corn straw would have the highest potential to provide thermal energy when data of lignin yields, higher heating values, and crops production are considered. The estimate suggests that in 2021 this alternate fuel could supply more than 1320 × 106 GJ yr−1 of thermal energy from the five crops analyzed, owing to the expected increase of the acreage and production for the most crops studied here in the next years. Recognizing that more studies are still needed, mainly in terms of economic feasibility, results of this work warn about possible additional benefits in developing the large‐scale production of second‐generation ethanol (via hydrolysis), in which lignin fractions from several crops could be separated and recovered for using them as new energy resource. © 2016 American Institute of Chemical Engineers Environ Prog, 36: 717–722, 2017

“…The high number of papers that cover lignin valorization, which have been identified by this work, introduces the research advances in the whole processing: the improvements in isolation, recovery, and characterization of lignin from biomass, the posterior depolymerization of lignin into monomers by chemical and biological means, and the final upgrading of the depolymerized lignin monomers to industrially relevant chemicals [41]. All these aspects have been deeply described by several reviews [42][43][44][45][46][47][48][49][50][51][52][53][54][55][56][57], and, therefore, the purpose of this section is just to summarize the most The most frequently selected keyword was Lignin, with 245 appearances. As Lignin was one of the words employed in the search engine, it is quite logical to find it among the most common keywords.…”

Alternatives for Chemical and Biochemical Lignin Valorization: Hot Topics from a Bibliometric Analysis of the Research Published During the 2000–2016 Period

A complete bibliometric analysis of the Scopus database was performed to identify the research trends related to lignin valorization from 2000 to 2016. The results from this analysis revealed an exponentially increasing number of publications and a high relevance of interdisciplinary collaboration. The simultaneous valorization of the three main components of lignocellulosic biomass (cellulose, hemicellulose, and lignin) has been revealed as a key aspect and optimal pretreatment is required for the subsequent lignin valorization. Research covers the determination of the lignin structure, isolation, and characterization; depolymerization by thermal and thermochemical methods; chemical, biochemical and biological conversion of depolymerized lignin; and lignin applications. Most methods for lignin depolymerization are focused on the selective cleavage of the β-O-4 linkage. Although many depolymerization methods have been developed, depolymerization with sodium hydroxide is the dominant process at industrial scale. Oxidative conversion of lignin is the most used method for the chemical lignin upgrading. Lignin uses can be classified according to its structure into lignin-derived aromatic compounds, lignin-derived carbon materials and lignin-derived polymeric materials. There are many advances in all approaches, but lignin-derived polymeric materials appear as a promising option.
