Predominance of anaerobic bacterial community over aerobic community contribute to intensify ‘oxygen minimum zone’ in the eastern Arabian Sea
(Elsevier, 2011)
The presence of a delicately poised mid-depth oxygen minimum zone (OMZ) makes the Arabian Sea a unique and important ecosystem. So far, various aspects responsible for its formation have been studied. However, the contributions ...
UV radiation and natural fluorescence linked primary production in Antarctic waters
(Marine Biological Association of India, 2001)
Primary productivity and chlorophyll values have been measured using an underwater profiling radiometer for the first time in the waters around Indian Antarctic Station (70°46'S & 11°44'E) in the summer of 1994. The profiles ...
Online Stable Isotope Analysis of Dissolved Organic Carbon Size Classes Using Size Exclusion Chromatography Coupled to an Isotope Ratio Mass Spectrometer
(American Chemical Society, 2012)
Stable isotopic content of dissolved organic carbon (delta sup(13)C-DOC) provides valuable information on its origin and fate. In an attempt to get additional insights into DOC cycling, we developed a method for delta ...
Diversity in transcripts and translational pattern of stress proteins in marine extremophiles
(Springer, 2011)
Extremophiles occur in a diverse range of habitats, from the frigid waters of Antarctic to the superheated plumes of hydrothermal vents. Their in-depth study could provide important insights into the biochemical, ecological ...
Iron released from ilmenite mineral sustains a phytoplankton community in microcosms
(Walter de Gruyter, 2011)
Natural biotic communities from Kalbadevi Bay were monitored in microcosms (1-l glass flasks) to test the hypothesis that iron released from ilmenite through microbial action contributes to proliferation of phytoplankton. ...
Astrobiological implications of dim light phototrophy in deep-sea red clays
(Elsevier, 2017)
Red clays of Central Indian Basin (CIB) under influence of trace of Rodriguez Triple Junction exhibited chemoautotrophy, low temperature hydrothermal alterations and photoautotrophic potential. Seamount flank TVBC-08, ...
Microbial activity promotes the enrichment of cobalt over nickel on hydrogenetic ferromanganese crusts
(Taylor & Francis, 2017)
The different mineral phases of the ferromanganese (Fe-Mn) crusts stem from the interaction of biotic and abiotic components. It is therefore vital to study the activity of these components to decipher their contribution ...
Bacterial standing stock, meiofauna and sediment-nutrient characteristics: Indicators of benthic disturbance in the Central Indian Basin
(Pergamon, 2001)
As a part of the environmental impact assessment studies for polymetallic nodule mining, the effect of simulated "benthic disturbance" caused by a benthic hydraulic disturber was studied in the Central Indian Basin (CIB). ...
Limno-tolerant bacteria govern nitrate concentration in Mandovi estuary, India
(Elsevier, 2009)
The spatial and temporal abundances of limno-tolerant and halo-tolerant bacteria were investigated in the tide-dominated Mandovi estuary along the west coast of India. These investigations were carried out in relation to ...
Sulfur cycle
(Elsevier, 2008)
Microbes, especially bacteria, play an important role in oxidative and reductive cycle of sulfur. The oxidative part of the cycle is mediated by photosynthetic bacteria in the presence of light energy and chemosynthetic ...
