“…Previously, Masai et al suggested that PDC is a possible inducer for LigAB PCA 4,5-dioxygenase. 23) These possibilities should be investigated further. At this juncture, the pro operon reconstituted with two plasmids in E. coli may serve as a useful experimental system to examine the regulatory aspect of the pro operon.…”

“…Nishiyama (21) identified large populations of culturable sphingomonads in decaying leaf residues in soil by counting colony-forming units on nutrient agar plates, and speculated that the residue is a major habitat for sphingomonads. In fact, sphingomonads have been detected in plant residues (17), and a variety of lignindegrading enzymes in one sphingomonad strain have been reported (16,23).…”

Abundance and Community Structure of Sphingomonads in Leaf Residues and Nearby Bulk Soil

We examined the abundance and community structure of sphingomonads in the decaying leaf residues of eight plant species as well as the nearby soil, by 16S rRNA gene-based real-time PCR and denaturing gradient gel electrophoresis. In the leaf residues, the sphingomonads generally accumulated to high levels, comprising approximately 15% of the total bacteria, and formed a community structure related to sampling locations. At least within the time period studied, their abundance in leaf residues changed, but their community structure was basically maintained. In soil, sphingomonads made up only 1.7% of total bacteria on average. The community structure of sphingomonads differed between the leaf residues and bulk soil, among plant plots, and among samples collected at different times. The results show that particular sphingomonad populations accumulate in leaf residues compared to the surrounding bulk soil under field conditions.

Organosolv fractionation (OF) is a promising method for lignocellulosic biomass biorefining to produce biofuels, biochemicals, and biomaterials. The fractionated polymeric components may be good feedstocks to produce bio‐based materials such as green polymers via chemical or biological conversion. However, related work to specify the bio‐based materials production via organosolv fractionation of lignocellulosic biomass is relatively scarce. In this work we have provided a comprehensive review of typical organosolv fractionation for isolating cellulose, hemicelluloses, and lignin, as well as the high value‐added monomer chemicals and functional materials derived from the fractionated components and their potential applications developed in recent years, primarily including the modified cellulose fibers for polymer materials, cellulose nanocrystals (CNCs), polysaccharide‐derived platform precursors for synthesis of bio‐based polymers, lignin‐derived dispersants, surfactants, carbon materials, and hemicellulose‐derived functional materials, etc. This work suggests that organosolv fractionation of lignocellulosic biomass could be a good entry to biomass refinery for high value‐added and functional materials production. However, there are still many challenges that should be overcome in terms of the fundamental, technical, and economic aspects for the organosolv fractionation process, formation of precursor compounds, synthesis of the bio‐based materials, design of product properties and functions, and the integration of the entire process. © 2019 Society of Chemical Industry and John Wiley & Sons, Ltd
