Present study investigates the impact of plant development on the structure and composition of root-associated bacterial community of groundnut (Arachis hypogaea) plant, an economically important oilseed legume. Relative abundance of total and active bacteria were studied in bulk soil and rhizosphere samples collected from different growth stages of groundnut plant by sequencing PCR-amplified 16S rRNA gene fragments from soil genomic DNA and reverse-transcribed soil community RNA. Plant growth promoting potential of cultivable rhizobacteria was evaluated using assays for inorganic phosphate solubilization and production of indole acetic acid, siderophores, biofilm, 1-amino-cyclopropane-1-carboxylate deaminase, laccase, and anti-fungal chemicals. Our study demonstrates that groundnut plant rhizosphere harbors a core microbiome populated by Proteobacteria, Actinobacteria, Firmicutes, Bacteroidetes, and Acidobacteria. A distinct bacterial assemblage at nodulation stage due to predominance of Flavobacteria and Actinobacteria in DNA and RNA derived libraries respectively was also observed. Majority of cultivable isolates exhibiting plant growth promoting activities belonged to Proteobacteria and Firmicutes. Of them, Pseudomonas indica and Bacillus megaterium were detected in the rhizosphere samples from all the developmental stages of groundnut plant. This polyphasic study establishes the impact of plant development on rhizobacterial population of groundnut and underscores the applicability of soil isolates as a reliable component in sustainable agriculture.

Ionic liquids (ILs) have now been acknowledged as reaction media for biotransformations. The first three examples were reported in this field in 2000, and since then, numerous applications have been reported for biocatalytic reactions using ILs. Two topics using ILs for enzymatic reactions have been reviewed from the standpoint of biocatalyst mediating organic synthesis; the first is "Biocatalysis in Ionic Liquids" which includes various types of biocatalytic reactions in ILs (section 2): (1) recent examples of lipase-mediated reactions using ILs as reaction media for biodiesel oil production and for sugar ester production, (2) oxidase-catalyzed reactions in ILs, (3) laccase-catalyzed reactions, (4) peroxidase-catalyzed reactions, (4) cytochrome-mediated reactions, (5) microbe-mediated hydrations, (6) protease-catalyzed reactions, (8) whole cell mediated asymmetric reduction of ketones, (10) acylase-catalyzed reactions, (11) glycosylation or cellulase-mediated hydrolysis of polysaccharides, (12) hydroxynitrile lyase-catalyzed reaction, (13) fluorinase or haloalkane dehydrogenase-catalyzed reaction, (14) luciferase-catalyzed reactions, and (15) biocatalytic promiscuity of enzymatic reactions for organic synthesis using ILs. The second is "Enzymes Activated by Ionic Liquids for Organic Synthesis", particularly describing the finding story of activation of lipases by the coating with a PEG-substituted IL (section 3). The author's opinion toward "Future Perspectives of Using ILs for Enzymatic Reactions" has also been discussed in section 4.
