A Review on the Phylogeography of Potentially Chemoautotrophic Bacteria from Major Vent and Seep Fauna and Their Contribution to Primary Production
(Taylor & Francis, 2018)
Though geochemically and microbially well-defined, the phylogeographic data of microbial symbionts in these highly productive vent and seep systems require a closer examination and synthesis. QIIME analysis of 16S rDNA of ...
Top down control of post-upwelling waters off Trivandrum: Indications from variability in DMS(P)
(Centre for Ocean and Environmental Studies, New Delhi, 2012)
Coastal upwelling is known to bring nutrient rich bottom waters to the surface. This change in chemistry triggers a series of cascading effects on the trophic levels of coastal ecosystems. Phytoplankton, besides being ...
Cobalt immobilization by manganese oxidizing bacteria from the Indian ridge system
(Springer, 2011)
Co immobilization by two manganese oxidizing isolates from Carlsberg Ridge waters (CR35 and CR48) was compared with that of Mn at same molar concentrations. At a lower concentration of 10 mu M, CR35 and CR48 immobilized ...
Marine drugs from sponge-microbe association - A review
(Molecular Diversity Preservation International, 2010)
The subject of this review is the biodiversity of marine sponges and associated microbes which have been reported to produce therapeutically important compounds, along with the contextual information on their geographic ...
16S rRNA-based bacterial diversity in the organic-rich sediments underlying oxygen-deficient waters of the eastern Arabian Sea
(Springer, 2011)
The eastern Arabian Sea has a unique and permanent oxygen minimum zone (OMZ) that extends along the western continental margin of India. The sediment below this region is rich in organic matter. This study describes the ...
Mathematical modeling of the evolution of a simple biological system
(India Environment Portal, Centre for Science and Environment, 2013)
As a part of teaching of physics it is common to record data on evolution of a physical system and then construct a mathematical model of the system. For example, movement of a simple pendulum can be recorded, and then a ...
Alkaline phosphatase activity at the southwest coast of India: A comparison of locations differently affected by upwelling..
(Elsevier, 2015)
The realization of the potential importance of phosphorus (P) as a limiting nutrient in marine ecosystem is increasing globally. Hence, the contribution of biotic variables in mobilizing this nutrient would be relevant ...
Nitrate levels modulate denitrification activity in tropical mangrove sediments (Goa, India)
(Springer, 2011)
A study to examine the short-term effect of nitrate and organic carbon addition on denitrification activity was carried out on sediments from a mangrove ecosystem prone to anthropogenic activities (Divar, Goa, India). ...
Immobilization of nickel by bacterial isolates from the Indian Ridge system and the chemical nature of the accumulated metal
(Taylor & Francis, 2010)
Bacterial isolates from Carlsberg-Ridge waters were tested for their ability to immobilize Ni. For this, test cultures were suspended for 60 d in seawater with and without added Ni at concentrations of 10 to 10,000 mu M. ...
Grazing of particle-associated bacteria - An elimination of the non-viable fraction
(Elsevier, 2017)
Quantification of bacteria being grazed by microzooplankton is gaining importance since they serve as energy subsidies for higher trophic levels which consequently influence fish production. Hence, grazing pressure on ...
