Abstract Background Open defecation is widespread in rural India, and few households have piped water connections. While government other efforts increased toilet coverage evaluations found limited immediate impacts on health, longer-term effects not been rigorously assessed. Methods We conducted a matched cohort study to assess the effectiveness of combined household-level sanitation intervention implemented by Gram Vikas (an Indian NGO) Odisha, India. Forty-five villages were randomly...

An extracellular thermo-alkali stable chitinase was obtained from Streptomyces chilikensis RC1830, a novel actinobacterial strain isolated the sediments of Chilika lake, India. Purification enzyme carried out by concentrating with centrifugal device followed chromatographic separation DEAE Sepharose ion exchange resin.The molecular weight 10.5 kDa as determined SDS-PAGE. The optimum pH and temperature for partially purified 7 60 °C. showed 40% activity at 11 after 24 h exposure room...

The taxonomic position of a novel actinomycete, strain RC 1831(T), isolated from the sediment fish dumping yard at Barkul village near Chilika Lake, Odisha, India, was determined by polyphasic approach. Based on morphological and chemotaxonomic characteristics isolate to belong genus Streptomyces. phylogenetic tree based its nearly complete 16S rRNA gene sequence (1428 nt) with representative strains showed that consistently falls into distinct phyletic line together Streptomyces...

Introduction Government efforts to address massive shortfalls in rural water and sanitation India have centred on construction of community sources toilets for selected households. However, deficiencies with quality quantity at the household level coverage actual use led Gram Vikas, a local non-governmental organization Odisha, India, develop an approach that provides household-level piped connections contingent full community-level toilet coverage. Methods This matched cohort study was...

A hydrophobic and biocompatible transdermal device has been developed from 2-hydroxyethyl methacrylate (HEMA) grafted carnboxymethyl guar gum (CMG)-functionalized multi-walled carbon nanotube (MWCNT) in situ composite membranes. The composites may be used for sustained delivery of diclofenac sodium. Supreme matrix–MWCNT interaction at 0.5 1 wt% MWCNT concentrations induces excellent copolymer-adsorbed fibrillar orientation compared to that 2 3 wt%. It successively leads efficient...

A facultatively anaerobic, Gram-stain-negative, rod-shaped, nitrogen-fixing, endophytic bacterial strain designated MP23T was isolated from the roots of Phragmites karka growing in Chilika Lagoon, Odisha, India. Strain slightly halophilic, and optimal NaCl concentration temperature for growth were 1 % 30 °C, respectively. On basis 16S rRNA gene sequence similarities, affiliated to family Enterobacteriaceae most closely related Mangrovibacter yixingensis KCTC 42181T plantisponsor DSM 19579T...

A novel actinobacterial strain RC1832T was isolated from the sediment of a fish dumping yard at Balugaon near Chilika Lake. The is halotolerant (15 % NaCl, w/v), alkali-tolerant (pH 7-10) and hydrolyzes chitin, starch, gelatin, cellulose, carboxymethyl Tween 80, tributyrin, lecithin casein. Apart showing typical genus-specific morphological chemotaxonomic features, comparision analysis complete 16S rRNA gene sequence clearly revealed that represented member genus Streptomyces. It exhibited...

Till date, only one draft genome has been reported within the genus Mangrovibacter. Here, we report second shotgun sequence of a Mangrovibacter sp. strain MP23 that was isolated from roots Phargmites karka (P. karka), an invasive weed growing in Chilika Lagoon, Odisha, India. Strain is facultative anaerobic, nitrogen-fixing endophytic bacteria grows optimally at 37 °C, 7.0 pH, and 1% NaCl concentration. The contains 4,947,475 bp with estimated G + C content 49.9% total 4392 protein coding...

Understanding spatiotemporal organization in bacteria under an external AC electric field is not only very interesting from a perspective of studying assembly and disassembly model biofilm but also provides insight into the intricate role anisotropic interaction with bacterial dynamics that can generate complex structures. In current study, using confocal microscopy, we demonstrate such assemblies monodisperse tetrad clusters Micrococcus luteus, environmental bacterium synthesized controlled...

ABSTRACT Halobacillus sp. strain KGW1 is a moderately halophilic, rod shaped, Gram-positive, yellow pigmented, alkaline protease-producing bacterium isolated from water sample Chilika Lake, Odisha, India. Sequencing of bacterial DNA assembled 3.68-Mb draft genome. The genome annotation analysis showed various gene clusters for tolerance to stress, such as elevated pH, salt concentration, and toxic metals.
