• Guidelines for performing lignin-first biorefining

  Energy & Environmental Science · 2020 · 835 citations

  With these guidelines, we aim to unite the lignin-first biorefining research field around best practices for performing or reporting feedstock analysis, reactor design, catalyst performance, and product yields.

• Assessing the Viability of Recovery of Hydroxycinnamic Acids from Lignocellulosic Biorefinery Alkaline Pretreatment Waste Streams

  ChemSusChem · 2020 · 75 citations

  Senior authorCorresponding

  Invited for this month's cover is the research team from the D.O.E. Great Lake Bioenergy Research Center (GLBRC) at the University of Wisconsin-Madison. The cover image shows how a diverse team with expertise in many different fields works together in an integrated fashion to address complex problems. Only when the whole system, from field to the liquid fuels and co-products, is assessed, can we identify the key parameters needed to design an economically viable biorefinery-based economy. Cover…

• Integrating lignin depolymerization with microbial funneling processes using agronomically relevant feedstocks

  Green Chemistry · 2022 · 54 citations

  This work shows the integration of reductive lignin depolymerization and microbial funneling with Novosphingobium aromaticivorans to produce 2-pyrone-4,6-dicarboxylic acid (PDC) in a lignocellulosic biorefinery.

• <i>p</i>HBMT1, a BAHD-family monolignol acyltransferase, mediates lignin acylation in poplar

  PLANT PHYSIOLOGY · 2021 · 36 citations

  Poplar (Populus) lignin is naturally acylated with p-hydroxybenzoate ester moieties. However, the enzyme(s) involved in the biosynthesis of the monolignol-p-hydroxybenzoates have remained largely unknown. Here, we performed an in vitro screen of the Populus trichocarpa BAHD acyltransferase superfamily (116 genes) using a wheatgerm cell-free translation system and found five enzymes capable of producing monolignol-p-hydroxybenzoates. We then compared the transcript abundance of the five correspon…
