“…The lignin barrier is overcome by the termites by a symbiotic relationship with a diverse microbial community, e.g., by exosymbiotic fungi and endosymbiotic gut flora (Maurice and Erdei 2018 ). Examples of aromatic degrading bacteria isolated from the gut flora include Proteobacteria (Harazono et al 2003 ; Kuhnigk and Konig 1997 ; Suman et al 2016 ; Tsegaye et al 2018 ; Van Dexter and Boopathy 2018 ), Actinobacteria (Chung et al 1994 ; Kuhnigk and Konig 1997 ; Watanabe et al 2003 ), and Firmicutes (Kuhnigk and Konig 1997 ), as well as the only Spirochaetes entry in the database (Lucey and Leadbetter 2014 ). Another enrichment reported in Table 4 for bacteria is the isolates from different man-made environments.…”

Lignin is a heterogeneous aromatic biopolymer and a major constituent of lignocellulosic biomass, such as wood and agricultural residues. Despite the high amount of aromatic carbon present, the severe recalcitrance of the lignin macromolecule makes it difficult to convert into value-added products. In nature, lignin and lignin-derived aromatic compounds are catabolized by a consortia of microbes specialized at breaking down the natural lignin and its constituents. In an attempt to bridge the gap between the fundamental knowledge on microbial lignin catabolism, and the recently emerging field of applied biotechnology for lignin biovalorization, we have developed the eLignin Microbial Database ( www.elignindatabase.com ), an openly available database that indexes data from the lignin bibliome, such as microorganisms, aromatic substrates, and metabolic pathways. In the present contribution, we introduce the eLignin database, use its dataset to map the reported ecological and biochemical diversity of the lignin microbial niches, and discuss the findings.

Bacterial systems have gained wide attention for depolymerization of lignocellulosic biomass, due to their high functional diversity and adaptability. To achieve the full microbial exploitation of lignocellulosic residues and the cost-effective production of bioproducts within a biorefinery, multiple metabolic pathways and enzymes of various specificities are required. In this work, highly diverse aerobic, mesophilic bacteria enriched from Keri Lake, a pristine marsh of increased biomass degradation and natural underground oil leaks, were explored for their metabolic versatility and enzymatic potential towards lignocellulosic substrates. A wide diversity of Pseudomonas species were obtained from enrichment cultures where organosolv lignin served as the sole carbon and energy source and were able to assimilate a range of lignin-associated aromatic compounds. Highly complex bacterial consortia were also enriched in cultures with xylan or carboxymethyl cellulose as sole carbon sources, belonging to Actinobacteria, Proteobacteria, Bacilli, Sphingobacteriia, and Flavobacteria. Numerous individual isolates could target diverse structural lignocellulose polysaccharides by expressing hydrolytic activities on crystalline or amorphous cellulose and xylan. Specific isolates showed increased potential for growth in lignin hydrolysates prepared from alkali pretreated agricultural wastes. The results suggest that Keri isolates represent a pool of effective lignocellulose degraders with significant potential for industrial applications in a lignocellulose biorefinery.
