Phytoplankton, Bacteria and Heterotrophic Nanoflagellate studies using ship and OCM-2 data along a coastal transect in the Arabian Sea
(Indian National Centre for Ocean Information Services (INCOIS), 2012)The coastal region of the central West coast of India is biologically productive and well known for its Mackerel and Sardine fishery. December is an active fishing month and fall in the post-monsoon period when coastal ... -
Production of macroaggregates from dissolved exopolymeric substances (EPS) of bacterial and diatom origin
(Elsevier, 2005)Exopolymeric substance (EPS) isolated from a pure culture of the marine bacterium Marinobacter sp. and the marine diatom Skeletonema costatum (axenic) were partially purified, chemically characterized and used as dissolved ... -
Production, biochemical characterization and detergents application of keratinase from the marine actinobacterium Actinoalloteichus sp. ma-32.
(AOCS, 2014)The present study is the first report on poultry feathers as a novel, inexpensive substrate for the production of a thermo- and detergent stable keratinase from a marine actinobacterium belonging to the genus Actinoalloteichus. ... -
Psychrotrophic metal tolerant bacteria for mobilisation of metals in Antarctic waters
(LIGHTS Research Foundation, 2012)Cold tolerant psychrotrophic bacteria abound in the Antarctic waters. While Antarctic krills are known to concentrate heavy metals at ppm levels, psychrotrophic bacteria from Antarctic fresh and marine waters have been ... -
Pyrrolizidine alkaloids pyrrolams A-D: A survey of synthetic efforts, biological activity, and studies on their stability
(Georg Thieme Verlag KG, 2012)Pyrrolam A is a microbial metabolite, structurally related to plant alkaloids of the necine-type, and was isolated from the bacterial strain of Streptomyces olivaceus along with the related alkaloids pyrrolams B-D. The ... -
Quantitative analyses of pollution-indicator and pathogenic bacteria in Mumbai waters from ballast water exchange perspective
(Springer, 2005)As large numbers of ships either take in ballast from or discharge their ballast into the Mumbai Harbor region, it is pertinent to quantify microorganisms of health concerns and suggest on the suitability of water for ... -
Retrieved bacteria from Noctiluca miliaris (green) bloom of the northeastern Arabian Sea
(Chinese Society for Oceanology and Limnology, 2013)In recent years, seasonal blooms of the dinoflagellate Noctiluca miliaris have appeared in the open-waters of the northern Arabian Sea (NAS). This study provides the first characterization of bacteria from a seasonal bloom ... -
Rhodovulum mangrovi sp. nov., a phototrophic alphaproteobacterium isolated from a mangrove forest sediment sample
(International Union of Microbiological Societies, 2014)A novel Gram-staining-negative, purple non-sulfur bacterium, strain AK41T, was isolated from a sediment sample collected from Coringa mangrove forest, Andhra Pradesh, India. A red–brownish-coloured culture was obtained on ... -
Seasonal variations of nitrate reducing and denitrifying bacteria utilizing hexadecane in Mandovi estuary, Goa, West Coast of India
(CSIR-NISCAIR, 2013)Mandovi estuary has a prolific population of heterotrophic bacteria due to the influx of nutrients including nitrate and organic hydrocarbons. Seasonal sampling at various locations along the estuary was carried out to ... -
Shivajiella indica gen. nov., sp. nov., a marine bacterium of the family "Cyclobacteriaceae" with nitrate reducing activity
(Elsevier, 2012)Novel orange pigmented, Gram-negative-staining, rod-shaped, non-motile, strictly aerobic strains designated NIO-S1 sup(T) and NIO-S2 were isolated from the water sample of a pond adjacent to the coast and an algal mat from ... -
Silanimonas mangrovi sp. nov., a member of the family Xanthomonadaceae isolated from mangrove sediment, and emended description of the genus Silanimonas
(International Union of Microbiological Societies, 2013)A novel Gram-negative, rod-shaped, motile bacterium, designated strain AK13 sup(T), was isolated from a sediment sample collected from mangrove of Namkhana, Sunderbans, West Bengal, India. Strain AK13 sup(T) was positive ... -
Some aspects of microbiological characteristics in the nearshore waters of Bombay
(CSIR-NISCAIR, 1994)Primary production, bacterial abundance, their generic composition, some of their biodegradative enzymes and heterotrophic uptake of labelled glucose were examined from the waters of Bombay harbour-Thana creek-Bassein creek ... -
Study of changes in bacterial and viral abundance in formaldehyde - Fixed water samples by epifluorescence microscopy
(Springer, 2011)Accurate measurement of bacterial and viral abundance in coastal marine environments is important to understand the dynamics of microbial communities in these ecosystems. In this study, the effect of formaldehyde preservation ... -
Sulfate reducing potential in an estuarine beach
(CSIR-NISCAIR, 1985)Sulfate reducing bacteria (SRB) and their activity (SRA) together with total anaerobic and aerobic bacterial flora were estimated during July 1982-April 1983 and July-August 1984 from 1, 3 and 5 cm depths using core samples. ... -
Temporally invariable bacterial community structure in the Arabian Sea oxygen minimum zone.
(Inter-Research, 2014)The Northeastern Arabian Sea (NEAS) is a recognized region of intense denitrification, with a 200 to 1200 m anoxic water column. We studied the abundance of bacteria, viral particles and the bacterial community (BC), in ... -
The effect of antibiotics on diatom communities
