In this paper, the biosynthesis process of phenolic compounds in plants is summarized, which includes the shikimate, pentose phosphate and phenylpropanoid pathways. Plant phenolic compounds can act as antioxidants, structural polymers (lignin), attractants (flavonoids and carotenoids), UV screens (...

Laboratory studies led us to conclude in 1951 that the insoluble humic acid content of peat is the geochemical agent responsible for the accumulation of uranium in bioliths. The accumulation of uranium occurs after the death of plants, the lignin of which is, in the course of humification, ...
As a unique and the second most abundant biopolymer (representing approximately 30% of biosyn- thesized organic carbon26) in vascular plants, lignin has been widely used in tracing terrigenous POC in rivers and oceans27,28. 70–80% of lignin are distributed in the surface layers of soils (O...
Second-generation biofuel technology is less well-established, as many of the feedstocks are high inlignocellulosic biomass. The processes to convert this to usable fuel are more complex than first-generation biofuels. Lignocellulosic materials, the complex matrix of lignin, pectin, and polysaccharides ...
which revealed thatThymeplants evolved recently in the family. Under the phylogenetic framework, we performed functional enrichment analysis of the genes on nodes that contained the most gene duplication events (> 50% support) and of relevant significant expanded gene families. These genes were high...
The gaps, identified via an importance performance analysis, represent the potential bottlenecks in the innovation diffusion process of bio-based products. Two cases were considered: The use of kraft lignin in phenol-formaldehyde (PF) resins for wood-based panels and the use of kraft lignin in ...
The origin of this organic material is the thermal degradation products of the wood constituents (i.e. cellulose, hemi-cellulose and lignin) that are released at low temperatures (300-500°C) without being further combusted due to poor mixing conditions. Freshly generated particles from ...
Hispidin (1) and bisnoryangonin (2) may polymerize during maturation of fungi and production of fungal lignin. Steglich and coworkers characterized 3,14¢-bihispidinyl (3) from P. pomaceus30 and hypholomines A (4) and B (5) and fasciculines A (6) and B (7) from Hypholoma fas...
Additionally, it should be noted that the lignin-derived compounds in bio-oil are difficult to reform into the syngas, since they can easily lead to the coke deposition on the catalyst. It has been found that the biomass particle size influences the content of lignin-derived compounds in bio...
