Dissimilatory nitrate reduction by Aspergillus terreus isolated from the seasonal oxygen minimum zone in the Arabian Sea
(BioMed Central, 2014)A wealth of microbial eukaryotes is adapted to life in oxygen-deficient marine environments. Evidence is accumulating that some of these eukaryotes survive anoxia by employing dissimilatory nitrate reduction, a strategy ... -
Diversity of nitrite reductase genes (nirS) in the denitrifying water column of the coastal Arabian Sea
(Inter-Research, 2004)Denitrification often occurs in the water column, underlying zones of intense productivity and decomposition in upwelling regions. In the denitrifying zone off the southwest coast of India, high concentrations of nitrite ... -
Double reductive cyclization: A facile synthesis of the indoloquinoline alkaloid cryptotackieine
(Elsevier, 2007)A new synthesis of the indoloquinoline alkaloid cryptotackieine, isolated from Cryptolepis sanguinolenta, is described which involves a Perkin reaction, a tandem double reduction-double cyclization reaction followed by ... -
Inorganic nitrogen and nitrate reduction in the Arabian Sea
(CSIR-NISCAIR, 1983)Concentration of inorganic nitrogen compounds within the euphotic zone is very low and it increases sharply in the thermocline layer. A steady decrease in the NO sub(3)-N occurs from south to north at intermediate depths. ... -
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 ... -
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 ... -
Shivajiella indica gen. nov., sp. nov., a marine bacterium of the family "Cyclobacteriaceae" with nitrate reducing activity
(Elsevier, 2012)Novel orange pigmented, Gram-negative-staining, rod-shaped, non-motile, strictly aerobic strains designated NIO-S1 sup(T) and NIO-S2 were isolated from the water sample of a pond adjacent to the coast and an algal mat from ... -
Some observations on use of siliceous mineral waters in reduction of corrosion in RCC structures
(Metal Finishers' Association of India, 1996)The corrosion-resisting characteristics of reinforcement in cement blended with siliceous mineral wastes viz. gold tailing and flyash have been evaluated by using an accelerated corrosion technique. The additions of these ... -
