Cobalt immobilization by manganese oxidizing bacteria from the Indian ridge system
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
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 ...
Hydrothermal Fe cycling and deep ocean organic carbon scavenging: Model-based evidence for significant POC supply to seafloor sediments
Submarine hydrothermal venting has recently been identified to have the potential to impact ocean biogeochemistry at the global scale. This is the case because processes active in hydrothermal plumes are so vigorous that ...
G model revisited: Seasonal changes in the kinetics of sulphate-reducing activity in the salterns of Ribander,Goa India
(Taylor & Francis, 2011)
The evaluate the contribution of Sulphate-Reducing Bacteria (SRB) to the carbon flux from marine salterns, sulfate reducing activity (SRA) was measured for a year (Sep 2000-Aug 2001). This covered the pre-monsoon period ...
Chemosynthesis in deep-sea red-clay: Linking concepts to probable martian life
Chemosynthetic microbial activity could share similarities between Martian and Earth systems. The present study examined the patterns of distribution of chemosynthetic bacteria in the deep-sea red clay sediments of CIB ...
Bacterial response to contrasting sediment geochemistry in the central Indian Basin
(International Association of Sedimentologists, 2011)
In order to investigate whether geochemical, physiographic and lithological differences in two end-member sedimentary settings could evoke varied microbe-sediment interactions, two 25 cm long sediment cores from contrasting ...
Ambient iron concentration regulates the sulfate reducing activity in the mangrove swamps of Diwar, Goa, India
In order to test the hypothesis that the ambient iron concentrations could regulate sulfate reducing activity (SRA) in mangrove areas, 10 cm cores were examined from test and reference sites. The test site at Diwar mangrove ...
Marine microbial ecology: Reminiscence of the status and some suggestions for the way forward
(CUSAT; India, 2012)
An attempt has been made to pick out a few aspects of the vast progress that the science of marine microbial ecology has made in the recent years and how we can move forward notwithstanding the challenges.
