Stimulation of sulfate-reducing activity at salt-saturation in the salterns of Ribandar, Goa, India
(Taylor & Francis, 2007)
In order to address the question if Sulphate Reducing Activity (SRA) ever gets arrested at salt saturation, it was measured at 0-2, 2-5 and 5-10 cm depth in sediment cores from the salt pans of Ribandar (Goa) using 35S – ...
Algal Bloom: Boon or Bane?
(NISCAIR, CSIR, 2006)
Algal blooms occur in response to nutrient deplete or replete conditions. Nitrogen fixing forms proliferate under oligotrophic conditions when nutrient levels are low. Replete conditions in response to upwelling creates ...
Bacterial contribution to mitigation of iron and manganese in mangrove sediments
(Elsevier, 2007)
The Mandovi and Chapora, (Goa, India) are two tropical estuaries lying in close geographic proximity on the west coast of India. Seasonal changes in down core variation of Fe, Mn and Total Organic Carbon (TOC) in the ...
Effect of carbon source concentration and culture duration on retreivability of bacteria from certain estuarine, coastal and offshore areas around the peninsular India.
(Indian Academy of Sciences, 2006)
Improved culture-based approaches efficiently compliment the limitations encountered in molecular methods to delineate the diversity and functions of uncultured organisms. The present study endeavours to reduce the anomaly ...
Microbial biomass and organic nutrients in the deep-sea sediments of the Central Indian Ocean Basin
(Taylor and Francis, 2001)
In order to assess the impact of deep-sea mining on the in situ benthic life, the microbial standing stock and concentration of organic nutrients in the deep-sea sediments of the Central Indian Ocean Basin in the Indian ...
Organic carbon and iron modulate nitrification rates in mangrove swamps of Goa, south west coast of India
(Elsevier, 2009)
Nitrification, fuelled by ammonium is the pivotal oxidative pathway to nitrogen cycling. In spite of its ecological significance, the factors regulating nitrification rates in the benthic realm remain poorly understood. ...
Bacterial response to contrasting geochemistry in the sediments of central Indian Ocean basin
(Regional Research laboratory, Bhubaneswar, 2005)
The latitudinal differences in geochemical and physiographic nature could evoke varied biological/microbiological response in the deep-sea benthic ecosystem of the Central Indian Ocean. Sediment cores have been examined ...
Rise of the dormant: Simulated disturbance improves culturable abundance, diversity, and functions of deep-sea bacteria of Central Indian Ocean Basin
(Taylor and Francis, 2005)
The abundance of baroduric bacteria from nine sediment cores (0-10 cm below sea floor) was examined for their response to simulated benthic disturbance in the Central Indian basin (CIB). While the total counts of bacteria ...
Seasonal dimethylsulfoniopropionate (DMSP) variability in Dona Paula Bay
(Elsevier, 2009)
Data on temporal variations of total dimethylsulfoniopropionate (DMSPt) and the environmental factors that influence DMSPt concentrations are important in understanding the biogeochemical cycling of organic sulfur compounds. ...
Long-term changes in microbial and biochemical parameters in the Central Indian Basin
(Elsevier, 2006)
Natural kilometer-scale spatial variability and seasonal variability in deepsea sediments at ~5000 m depth was studied at 2 reference sites in the Central Indian Basin. Biochemical parameters such as the labile organic ...
