Genome Announcements | Year: 2016

The draft genome sequence of Lactobacillus plantarum Kanjika 2007, isolated from the South Indian staple, medicinal, and traditional food kanjika, is reported here. The whole genome consists of 3.16 Mb with a G+C content of 44.7% and 3,009 proteincoding genes, 78 tRNAs, and 4rRNAs (5S-23S-16S). © 2016 Divyashri et al.

A Prussian blue/carbon dot (PB/CD) nanocomposite was synthesised and used as a visible-light active photocatalyst for the oxidative cyanation of tertiary amines to α-aminonitriles by using NaCN/acetic acid as a cyanide source and H2O2 as an oxidant. The developed photocatalyst afforded high yields of products after 8 h of visible light irradiation at room temperature. The catalyst was recycled and reused several times without any significant loss in its activity. © 2016 The Royal Society of Chemistry and Owner Societies.

Polymer functionalized surfaces are important components of various sensors, solar cells and molecular electronic devices. In this context, the use of self-assembled monolayer (SAM) formation and subsequent reactions on the surface have attracted a lot of interest due to its stability, reliability and excellent control over orientation of functional groups. The chemical reactions to be employed on a SAM must ensure an effective functional group conversion while the reaction conditions must be mild enough to retain the structural integrity. This synthetic constraint has no universal solution; specific strategies such as "graft from", "graft to", "graft through" or "direct" immobilization approaches are employed depending on the nature of the substrate, polymer and its area of applications. We have reviewed current developments in the methodology of immobilization of a polymer in the first part of the article. Special emphasis has been given to the merits and demerits of certain methods. Another issue concerns the utility - demonstrated or perceived - of conjugated or non-conjugated macromolecules anchored on a functionally decorated SAM in the areas of material science and biotechnology. In the last part of the review article, we looked at the collective research efforts towards SAM-based polymer devices and identified major pointers of progress (236 references).

Porous lanthanum phosphate substrates, obtained by an environmentally benign colloidal forming process employing methyl cellulose, are reported here as excellent adsorbents of perchlorate with >98% efficiency and with 100% reusability. Additionally, the effectiveness of such substrates as biocatalyst supports that facilitate biofilm formation of perchlorate reducing microbes (Serratia marcescens NIIST 5) is also demonstrated for the first time. The adsorption of perchlorate ions is attributed to the pore structure of lanthanum phosphate substrate and the microbial attachment is primarily ascribed to its intrinsic hydrophobic property. Lanthanum phosphate thus emerges as a dual functional material that possesses an integrated adsorption/bioremediation property for the effective removal of ClO4- which is an increasingly important environmental contaminant. © 2014 Elsevier B.V.

An efficient and eco-friendly synthesis of functionalized pyrroles using recyclable montmorillonite clay K10 and KSF catalysts has been described. The clay-catalyzed domino four-component coupling (4CC) of amines, aldehydes, 1,3-dicarbonyl compounds and nitroalkanes produced functionalized pyrroles in good yields. The developed methods offers advantages such as operational simplicity, economical, simple workup, use of commercial recyclable catalyst and excellent functional group compatibility to synthesize structurally diverse pyrroles. This is the first report on the use of heterogeneous catalyst for this 4CC. This journal is © The Royal Society of Chemistry 2013.
