  • ABSTRACT SONG, XIAO. Investigating the Role and Structure of Free Radicals in Lignin Biosynthesis
    ABSTRACT SONG, XIAO. Investigating the Role and Structure of Free Radicals in Lignin Biosynthesis. (Under the direction of Prof. Tatyana Smirnova). Lignin is the second most abundant biopolymer on earth after cellulose that contributes to the overall viability and sustainability of the plant kingdom. Understanding molecular details of the lignin formation and cross-linking is of fundamental importance to production of biomass streams. Although the processes of monolignols oxidative dehydrogenation, polymerization and cross-linking to cell walls are proposed to occur through a free radical mechanism, the specific details remain elusive. In order to understand molecular mechanisms of these reactions, we investigated formation of radicals during enzyme-catalyzed (HRP or Laccase) oxidative dehydrogenation of twelve monolignols. To characterize short-lived radicals formed during the enzymatic reaction we employed EPR spectroscopy in combination with spin-trapping technique and deduced the structures and spatial conformations of radicals. We also utilized continuous- flow EPR in combination with enzyme surface immobilization to detect the formation of transient monolignol radicals and thus patterned their isotropic hyperfine parameters that allow for the mapping of unpaired electron distribution. Polymerized radicals formed as a result of the coupling of enzyme-generated monolignol radicals. The effective -factors and ∆퐻푃−푃 of EPR spectra of polymerized radicals could be used as a reference to identify the polymeric radicals obtained from monolignols by different methods and paramagnetic species in natural lignin. We further generated a monolignol radical using consecutive enzymatic deglucosidation and oxidative dehydrogenation of a monolignol glucoside. This approach could be used to probe the isotropic hyperfine interactions of radical structures of monolignols with limited solubility in water by continuous-flow EPR method, especially for monolignol hydroxycinnamate conjugate compounds whose isotropic hyperfine component have not been studied yet.

Herein, we investigated the expression pattern of a CCoAOMT orthologue from various tissues and organs during development, and in response to different environmental cues. The full-length CCoAOMT orthologue of kenaf consists of a 744 bp open reading frame (ORF), encoding for 247 amino acids of 27.91 kDa and an isoelectric point (pI) of 5.43. The deduced amino acids of CCoAOMT evidenced a high degree of identity (up to 84%) with other plant CCoAOMT sequences. Phylogenetic analysis demonstrated its close relationship with the CCoAOMT of Gossypium hirsutum (ACQ59096).

Received: 4 September 2020; Accepted: 8 October 2020; Published: 12 October 2020 Abstract: Mediterranean plant Helichrysum italicum represents a rich source of versatile bioactive compounds with potential benefits for human health. Despite extensive research on the plant’s active constituents, little attention has yet been paid to characterizing the relationship between its intra-specific genetic diversity and metabolite profile. The study aimed to determine metabolic profile of H. italicum ssp. italicum (HII) and ssp. tyrrhenicum (HIT) cultivated on the experimental plantation in Slovenia and to compare the chemical composition of extracts regarding the solvent extraction process. Extracts were prepared upon conventional extract preparation procedures: maceration with 50 % methanol or ethanol and cold or hot water infusion and analyzed using High Performance Liquid Chromatography-Diode Array Detection-Electrospray Ionization-Quadrupole Time-of-Flight-Mass Spectrometry (HPLC-DAD-ESI-QTOF-MS).

There is an urgent necessity for novel drug discovery to increase effective Citation: Promraksa, B.; Katrun, P.; treatment possibilities. A recent study reported that lignin derived from Scoparia dulcis can cause Phetcharaburanin, J.; Kittirat, Y.; CCA cell inhibition. However, there is no evidence on the inhibitory effect of coniferyl alcohol (CA), Namwat, N.; Techasen, A.; Li, J.V.; which is recognized as a major monolignol-monomer forming a very complex structure of lignin.

  • Wood Based Lignin Reactions Important to the Biorefinery and Pulp and Paper Industries
    PEER-REVIEWED REVIEW ARTICLE bioresources.com Wood Based Lignin Reactions Important to the Biorefinery and Pulp and Paper Industries Ricardo B. Santos,a,* Peter W. Hart,a Hasan Jameel,b and Hou-min Chang b The cleavage of lignin bonds in a wood matrix is an important step in the processes employed in both the biorefinery and pulp and paper industries. β-O-4 ether linkages are susceptible to both acidic and alkaline hydrolysis. The cleavage of α-ether linkages rapidly occurs under mildly acidic reaction conditions, resulting in lower molecular weight lignin fragments. Acidic reactions are typically employed in the biorefinery industries, while alkaline reactions are more typically employed in the pulp and paper industries, especially in the kraft pulping process. By better understanding lignin reactions and reaction conditions, it may be possible to improve silvicultural and breeding programs to enhance the formation of easily removable lignin, as opposed to more chemically resistant lignin structures. In hardwood species, the S/G ratio has been successfully correlated to the amount of β-O-4 ether linkages present in the lignin and the ease of pulping reactions.

Cellulose is a partially crystalline polymer that is reasonably chemical-resistant and has the ability to form hydrogen bonds.
