Importance of contextual information for harnessing microbial resources from polar regions
(LIGHTS Research Foundation, 2013)
With growing interest in scientific and commercial pursuits extending up to the poles, new challenges for both environmental diplomacy and governance could be envisaged. Polar regions could be veritable store house for ...
Manganese Oxidation by Bacteria: Biogeochemical Aspects
(Springer-Verlag, 2011)
Manganese is an essential trace metal that is not as readily oxidizable like iron. Several bacterial groups posses the ability to oxidize Mn effectively competing with chemical oxidation. The oxides of Mn are the strongest ...
Insights into the structural and functional aspects of rela by molecular modeling and docking calculations.
(IJPPS publishes, 2014)
RelA (ppGpp synthetase I) has been reported as an excellent drug target due to its correlation with virulence induction in bacteria. The aim of present investigation is to provide a deeper understanding of the structural ...
Mobilization of manganese by basalt associated Mn(II)-oxidizing bacteria from the Indian Ridge System
(Elsevier, 2014)
The Indian Ridge System basalt bearing Mn-oxide coatings had todorokite as the major and birnesite as the minor mineral. We posit that microorganisms associated with these basalts participate in the oxidation of Mn and ...
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 ...
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 ...
Nitrate reducing activity pervades surface waters during upwelling.
(Elsevier, 2014)
Nitrate reducing activity (NRA) is known to be mediated by microaerophilic to anaerobic bacteria and generally occurs in the sub-surface waters. However, we hypothesize that NRA could become prominent in the surface waters ...
