“…Pathway 4 has been observed in L. edodes in which ferulic acid is converted to 2-hydroxyferulic acid and further to 2,3,4-trihydroxycinnamic acid followed by the cleavage of the aromatic ring (Crestini and Sermanni, 1994). Pathway 5 has been observed in the bacteria Enterobacter cloacae and Streptomyces albogriseolus, and the ascomycete Penicillium rubens, in which ferulic acid is demethylated to caffeic acid and further converted to protocatechuic acid (Buraimoh et al, 2017;Grbić-Galić and La Pat-Polasko, 1985;Tillett and Walker, 1990). The enzymes catalyzing these reactions have not yet been identified.…”

Aromatic compounds derived from lignin are of great interest for renewable biotechnical applications. They can serve in many industries e.g. as biochemical building blocks for bioplastics or biofuels, or as antioxidants, flavor agents or food preservatives. In nature, lignin is degraded by microorganisms, which results in the release of homocyclic aromatic compounds. Homocyclic aromatic compounds can also be linked to polysaccharides, tannins and even found freely in plant biomass. As these compounds are often toxic to microbes already at low concentrations, they need to be degraded or converted to less toxic forms. Prior to ring cleavage, the plant-and lignin-derived aromatic compounds are converted to seven central ring-fission intermediates, i.e. catechol, protocatechuic acid, hydroxyquinol, hydroquinone, gentisic acid, gallic acid and pyrogallol through complex aromatic metabolic pathways and used as energy source in the tricarboxylic acid cycle. Over the decades, bacterial aromatic metabolism has been described in great detail. However, the studies on fungal aromatic pathways are scattered over different pathways and species, complicating a comprehensive view of fungal aromatic metabolism. In this review, we depicted the similarities and differences of the reported aromatic metabolic pathways in fungi and bacteria. Although both microorganisms share the main conversion routes, many alternative pathways are observed in fungi. Understanding the microbial aromatic metabolic pathways could lead to metabolic engineering for strain improvement and promote valorization of lignin and related aromatic compounds.

Antarctic have been suggested as an attractive source for antibiotics discovery and members of Streptomyces genus have historically been studied as natural producers of antimicrobial metabolites. Nonetheless, our knowledge on antibiotic-producing Streptomyces from Antarctic is very limited. In this study, the antimicrobial activity of organic extracts from Antarctic Streptomyces strains was evaluated by disk diffusion assays and minimum inhibitory concentration. The strain Streptomyces sp. So13.3 showed the greatest antibiotic activity (MIC = 15.6 μg/mL) against Gram-positive bacteria and growth reduction of Gram‒negative pathogens. The bioactive fraction in the crude extract was revealed by TLC‒bioautography at R f = 0.78 with molecular weight between 148 and 624 m/z detected by LC-ESI-MS/MS. The strain So13.3 was taxonomically affiliated as Streptomyces fildesensis . Whole genome sequencing and analysis suggested a 9.47 Mb genome size with 42 predicted biosynthetic gene clusters (BGCs) and 56 putative clusters representing a 22% of total genome content. Interestingly, a large number of them (11 of 42 BGCs and 40 of 56 putative BGCs), did not show similarities with other known BGCs. Our results highlight the potential of the Antarctic Streptomyces strains as a promising source of novel antimicrobials, particularly the strain Streptomyces fildesensis So13.3, which first draft genome is reported in this work.

“…The most evident route toward ferulic acid is a one-step reaction from feruloyl-CoA, possibly committed via a thioesterase (Dauwe et al, 2007;Mir Derikvand et al, 2008). Buraimoh et al (2016) reported that Streptomyces albogriseolus fully utilized coniferyl alcohol as a substrate, leading to the generation of ferulic acid, the generally known immediate metabolic product of coniferyl alcohol degradation, coniferylaldehyde, was not observed in any of the chromatograms, indicating that ferulic acid might be synthesized directly from coniferyl alcohol via an alternative pathway. Metabolic flux analyses are needed to reveal such a pathway, if it exists.…”
