Data for: Techno-economic and environmental assessment of converting mixed prairie to renewable natural gas with co-product hydroxycinnamic acid, Iowa, USA, 2022-2023.
This dataset compiles model outputs, parameter sets, and documentation supporting a techno‑economic analysis (TEA) and life‑cycle assessment (LCA) of co‑digesting beef cattle manure with pretreated mixed prairie biomass to produce renewable natural gas (RNG), with hydroxycinnamic acids (HCA) and digestate‑derived biochar co‑products. It accompanies the study by Katherine Wild, Elmin Rahic, Lisa A Schulte Moore, and Mark Mba Wright "Techno-economic and environmental assessment of converting mixed prairie to renewable natural gas with co-product hydroxycinnamic acid," in Biofuels, Bioproducts, & Biorefining, 2024 (https://doi.org/10.1002/bbb.2710). The integrated simulation and assessment framework quantifies process performance, economics, and greenhouse‑gas intensity across five scenarios representing combinations of alkaline‑ethanol pretreatment for HCA extraction, liquid recirculation fractions, and biochar addition. This data collection includes: stream‑level mass flow/composition tables for each scenario; RNG, biochar, and HCA annual production summaries; literature‑based methane/biogas yield benchmarks; equipment‑level capital costs; TEA assumptions; emission‑factor inventories and displacement credits; and full sensitivity/uncertainty matrices for MFSP and GWP.
Hydroxycinnamic acid extraction from prairie biomass for enhancing performance in anaerobic digestion, Iowa, 2021-2022.
This dataset contains a series of batch and continuous anaerobic digestion (AD) experiments that document the effects of hydroxycinnamic acid (HCA) extraction as a pretreatment strategy for prairie biomass to enhance methane production and digestion performance. It includes data on chemical composition of raw inputs (prairie biomass, manure, inoculum), including elemental and solids content; methane and biogas yields under various conditions: untreated vs. HCA-treated biomass, co-digestion with manure at different ratios, and operational enhancements such as biochar supplementation and liquid digestate recirculation; digestate characteristics, including pH, ammonia concentration, and total phenolic content, under different treatment and operational scenarios; optimization data for HCA extraction, detailing the influence of temperature and time on HCA yield and lignin removal; and HCA composition data, including cumulative and species-specific yields (ferulic and p-coumaric acids), and acetyl bromide soluble lignin content.

Fig. 5. Comparison of the entrance architectures of TaACT2 and HvACT1-1, and structure-based sequence alignment. (A) Surface diagram of TaACT2 viewed from the acyl acceptor entrance side. The loops of HvACT1-1 (K206–E222 and A350–D364) are shown as ribbon (light brown), as the corresponding regions in TaACT2 were not determined, except for 358LVTTA362. Note that the structure of 211AHDV214 in HvACT1-1 is also missing (Yamane et al., 2020). To improve visibility, 358LVTTA362 of TaACT2 is shown as ribbon and transparent surface diagrams. The cavity for substrate binding, Phe39, and His153 in TaACT2, are indicated in deep blue, pink, and orange, respectively. To clarify the possible substrate binding site, SbHCT, complexed with p-coumaroylshikimate (PDB ID 4KEC), was superimposed on TaACT2, and the structure of the ligand is shown as stick (p-coumaroyl moiety) and wire (shikimate moiety) in magenta. (B) Structures of the entrance for the acyl acceptor. The loops located near the entrance are shown in ribbon diagram, and Phe39 and the catalytic center His are shown as sticks (TaACT2: cyan; HvACT1-1: light brown). The His residues in TaACT2 and HvACT1-1 are indicated in white and green, respectively. The structure of the loop in TaACT2 (363DAAE366) was not determined and the corresponding region in HvACT1-1 is indicated in yellow. The blue in stick format indicates nitrogen atoms. (C) Multiple sequence alignment based on the tertiary structures of TaACT2, HvACT1-1, SbHCT, and AtHCT. Regions, structures of which were not determined, are indicated by grey characters. The residues that are estimated to constitute the substrate binding pockets are shaded in cyan. Closed orange circle indicates Phe39. HXXXD and DFGWG motifs are indicated by closed red triangles. The catalytic center His residues are surrounded by a red frame. Clade IV-specific motif of the BAHD superfamily, the EVDSWL and VLWAFP motifs, are indicated by open green triangles. The Arg residues that interact with the carboxy group of shikimate in SbHCT and AtHCT were indicated by an orange diamond. The molecular graphics were produced using UCSF Chimera (A) and PyMOL (Schrodinger) (B), and structure-based alignment (C) was performed using UCSF Chimera.

The Glu, Asp, and Trp in the motif of HvACT1-1 (yellow) and TaACT1-1 (cyan) and their corresponding residues in SbHCT (pink; PDB 4KEC), and AtHCT (light grey; PDB 5KJU) are shown with sticks. The catalytic His and the Arg that interact with the carboxy group of shikimate in SbHCT and AtHCT are also shown. Ala360 and 362 of barley and wheat ACTs, respectively, correspond to the Arg in HCTs. p-Coumaroylshikimate molecules bounded to the crystals of SbHCT and AtHCT are presented. Note that the structures of HCTs were those of holoenzymes complexed with a natural product, p-coumaroylshikimate.

Fig. 3 in Molecular and structural characterization of agmatine coumaroyltransferase in Triticeae, the key regulator of hydroxycinnamic acid amide accumulation
Fig. 3. Relative transcription levels of ACTs in barley, wheat, and rice shoots. The absolute quantity of transcripts of HvACT1 (A), HvACT2 (B), TaACT1 (C), TaACT2 (D), OsAHT1 (E), and HmACT (F) was quantified using real-time PCR and normalized to actin level. The relative transcription levels were described as the percentage ratio to HvACT1 at 48 h. The data are shown as means ± standard deviation (n = 6). Different characters of the bars indicate significant differences (p <0.05, Tukey–Kramer test).
