Mixed response in bacterial and biochemical variables to simulated sand mining in placer-rich beach sediments, Ratnagiri, West coast of India
(Springer, 2012)
The influence of mechanical disturbance of sediment-akin to small scale mining on bacterial community and biochemical variables was investigated at Kalbadevi beach, Ratnagiri, a placer-rich beach ecosystem which is a ...
Nitrogen-limited mangrove ecosystems conserve N through dissimilatory nitrate reduction to ammonium
(Nature Publishing Group, 2012)
Earlier observations in mangrove sediments of Goa, India have shown denitrification to be a major pathway for N loss However, percentage of total nitrate transformed through complete denitrification accounted for less than ...
Bacterial diversity in relatively pristine and anthropogenically-influenced mangrove ecosystems (Goa, India)
(Sociedade Brasileira de Microbiologia, 2014)
To appreciate differences in benthic bacterial community composition at the relatively pristine Tuvem and the anthropogenically-influenced Divar mangrove ecosystems in Goa, India, parallel tag sequencing of the V6 region ...
Environmental drivers of temporal variability in DMS (P) in the surfwater of a tropical intertidal beach
(Discovery Publication, 2014)
Tropical estuaries are potential contributors of dimethylsulfide (DMS), a climatically relevant volatile sulfur compound and its precursor dimethylsulphoniopropionate (DMSP) In order to understand the distribution of DMS ...
Hydrothermal Fe cycling and deep ocean organic carbon scavenging: Model-based evidence for significant POC supply to seafloor sediments
(Elsevier, 2015)
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
(Planex, 2014)
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
(Elsevier, 2011)
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.
