PCR screening for the surfactin (sfp) gene in marine Bacillus strains and its molecular characterization from Bacillus tequilensis NIOS11
(The Scientific and Technological Research Council of Turkey, 2013)
The sfp gene responsible for surfactin production was screened from the DNA extracts of 37 Bacillus spp. whose identity was confirmed by 16S rRNA gene sequence analyses. PCR screening revealed amplification of sfp gene ...
Production of dimethylsulphide during the seasonal anoxia off Goa
(Springer, 2012)
Subsurface waters over the western Indian continental shelf experience seasonal anoxia towards the end of the southwest monsoon season. During a 3-day study carried out at the Candolim time series site (off the coast of ...
The origin of ferro-manganese oxide coated pumice from the Central Indian Ocean Basin
(Elsevier, 2013)
Pumice clasts, partially and fully coated with ferro-manganese oxide from the Central Indian Ocean Basin (CIOB) were analysed for major, trace and rare earth elements; and glass and mineral grain chemistry to assess their ...
Abrupt climate-induced changes in carbonate burial in the Arabian Sea: Causes and consequences.
(American Geophysical Union, 2014)
We present high-resolution records of aragonite contents and pteropods abundance in two sediment cores (SK 17 and MD 76–131) within the Oxygen Minimum Zone (OMZ) of the eastern Arabian Sea. We show large increases in ...
Microwave-assisted reductive cyclization: An easy entry to the indoloquinolines and spiro[2H-indole-2,30-oxindole].
(Royal Society of Chemistry, 2014)
Synthesis of two linear indoloquinolines i.e. 6H-indolo[2,3-b]quinoline & 11-hydroxy-10H-indolo[3,2-b]quinoline, and spiro[2H-indole-2,3'-oxindole] from a common intermediate, (2-nitrophenyl)methylidene-dihydro-indolone ...
Elucidation of the tidal influence on bacterial populations in a monsoon influenced estuary through simultaneous observations
(Springer, 2017)
The influence of tides on bacterial populations in a monsoon influenced tropical estuary was assessed through fine resolution sampling (1 to 3 h) during spring and neap tides from mouth to the freshwater end at four stations ...
A note on chemical composition and origin of ferromanganese oxide coated and uncoated pumice samples from central Indian Ocean basin
(Geological Society of India, 2016)
Pumice are explosive volcanic product, occur as uncoated or coated with ferromanganese (Fe-Mn) oxide and resides in association with ferromanganese nodules on the seabed in Central Indian Ocean Basin (CIOB). The older Fe-Mn ...
Denitrification prevails over anammox in tropical mangrove sediments (Goa, India)
(Elsevier, 2012)
Denitrification, anammox (Anx) and di-nitrogen fixation were examined in two mangrove ecosystems- the anthropogenically influenced Divar and the relatively pristine Tuvem. Stratified sampling at 2 cm increments from 0 to ...
Observed internal tides and near-inertial waves on the continental shelf and slope off Jaigarh, central west coast of India
(Elsevier, 2016)
The characteristics of internal tides (ITs) and near-inertial waves (NIWs) on the continental shelf and slope off Jaigarh (17degreeN), central west coast of India were studied. Eight-month (March–October) long Acoustic ...
Distribution and sources of particulate organic matter in the Indian monsoonal estuaries during monsoon
(American Geophysical Union, 2014)
The distribution and sources of particulate organic carbon (POC) and nitrogen (PN) in 27 Indian estuaries were examined during the monsoon using the content and isotopic composition of carbon and nitrogen. Higher phytoplankton ...
