Base-Catalyzed Depolymerization of Solid Lignin-Rich Streams Enables Microbial Conversion

Abstract: Lignin valorization offers significant potential to enhance the economic viability of lignocellulosic biorefineries. However, because of its heterogeneous and recalcitrant nature, conversion of lignin to value-added coproducts remains a considerable technical challenge. In this study, we employ base-catalyzed depolymerization (BCD) using a process-relevant solid lignin stream produced via deacetylation, mechanical refining, and enzymatic hydrolysis to enable biological lignin conversion. BCD was conducted with… Show more

“…This is in agreement with reports by Salvachúa et al on P. fluorescens Pf-5, which was found able to depolymerize HMW lignin, but was not able to consume the produced monomers [21]. In contrast to a few previous reports on the ability of P. putida KT2440 to breakdown HMW lignin [20, 21], no such behavior was observed for EM42 strain, despite its genetic similarities with KT2440 [37]. This could be due to the different lignin source used in this study, since the lignin obtained from corn stover differs much from the technical lignin (Indulin AT) in terms of the structure, primary building blocks and successive breakdown products [45, 46].…”

“…A study has been conducted focusing on consolidated bioprocessing (CBP) toward lignin degradation using different types of bacteria under nitrogen‐limiting and nutrient‐rich conditions . The results showed that Pseudomonas putida , Rhodotorula mucilaginosa , and Corynebacterium glutamicum demonstrated strong tolerance to alkaline pretreatment liquor and could rapidly consume the lignin‐derived monomers …”

“…Although pathways have been designed and tested for the production of adipic acid from sugars, there are always going to be cost implications and reservations about using food to make chemicals, and although counterarguments involving nth‐generation biorefineries abound, the real question is whether something besides sugars could be used in the first place. Recent work by Beckham and co‐workers at the US National Renewable Energy Laboratory describes the use of an engineered strain of the microorganism Pseudomonas putida to “biologically funnel” lignin directly towards cis ‐ cis muconic acid, a natural product that can be easily hydrogenated to adipic acid . As if that were not enough, trans ‐ trans muconic esters, which can be produced by isomerization of the natural cis ‐ cis isomer, undergo Diels–Alder cycloaddition with ethylene to give cyclohexene products, the catalytic dehydrogenation of which gives terephthalate (Scheme ), another multimillion‐ton commodity chemical .…”
