A novel Gram-negative gamma-proteobacterium, non-sporulating motile, rod or coccus-shaped bacterium designated as strain PKS7 was isolated from a sediment sample collected from Chilika Lake, Odisha, India and characterized taxonomically using a polyphasic approach. The major quinone was Q8 and major cellular fatty acids were C, C, Cw8c Cw8c, C3-OH. The chemotaxonomic features confirmed the isolate to be a member of genus Rheinheimera.

An extracellular thermo-alkali stable chitinase was obtained from RC1830, a novel actinobacterial strain isolated from the sediments of Chilika lake, India. Purification of the enzyme was carried out by concentrating the enzyme with centrifugal device followed by chromatographic separation by DEAE Sepharose ion exchange resin.The molecular weight of the enzyme was 10.

moderately halophilic spore forming, motile, Gram-positive, rod-shaped bacterial strain designated as KGW1 was isolated from water sample of Chilika Lake and characterized taxonomically using polyphasic approach. The strain grew in the presence of 0-25% (w/v) NaCl in marine salt agar media, hydrolyzes casein, and gelatin and shows presence of alkaline proteases. The major cell wall menaquinone was MK7 and major cellular fatty acids were anteiso-C (44.

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

The taxonomic position of a novel actinomycete, strain RC 1831(T), isolated from the sediment of a fish dumping yard at Barkul village near Chilika Lake, Odisha, India, was determined by a polyphasic approach. Based on morphological and chemotaxonomic characteristics the isolate was determined to belong to the genus Streptomyces. The phylogenetic tree based on its nearly complete 16S rRNA gene sequence (1428 nt) with representative strains showed that the strain consistently falls into a distinct phyletic line together with Streptomyces glaucosporus DSM 41689(T) (98.

Green, hydrophobic device for controlled transdermal release of diclofenac sodium was designed from in situ nanosilica/acrylic acid grafted guargum membranes. Best grafting condition was assigned and nanocomposites were formed in situ using varying proportions of aqueous nanosilica sol. Nanocomposite/drug conjugates were formed by bringing down the medium pH from 9.
