Functional and Structural Roles of the Major Facilitator Superfamily Bacterial Multidrug Efflux Pumps
(MDPI AG, 2020)Pathogenic microorganisms that are multidrug-resistant can pose severe clinical and public health concerns. In particular, bacterial multidrug efflux transporters of the major facilitator superfamily constitute a notable ... -
Time course nutrient uptake study of some intertidal rocky shore macroalgae and the limiting effect due to synergistic interaction
(NISCAIR, 2020)The time course nutrient uptake study of some intertidal rocky shore macroalgae showed a marked variation in the uptake of nutrients. In the present study, Caulerpa sertularioides, Padina tetrastomatica, Sargassum cinctum, ... -
Shell weights of foraminifera trace atmospheric CO2 from the Miocene to Pleistocene in the central Equatorial Indian Ocean
(Springer, 2020)The Maldives Sea is a region dominated by the South Asian monsoon (SAM) and at present, a CO2 source to the atmosphere. Ti/Al elemental ratios from Site U1467 and U1468 recovered from the Maldives Sea show a gradual increase ... -
Magma genesis at Andaman volcanic arc regime, Northeastern Indian Ocean: Role of slab-mantle interaction
(International Union of Geological Sciences, 2020)This study reports new petrological and geochemical data of submarine volcanic rocks dredged from the Andaman arc, northeastern Indian Ocean and evaluates their petrogenetic and tectonic implications. The studied samples ... -
Pesticide application inhibit the microbial carbonic anhydrase-mediated carbon sequestration in a soil microcosm
(Springer, 2020)Heterotrophic system for carbon sequestration is gaining importance in the recent decades. Carbonic anhydrase (CA) is a major enzyme involved in carbon sequestration and biomineralization process. In this paper, we evaluate ... -
DNA barcoding of horn snail Telescopium telescopium (Linnaeus C, 1758) using mt-COI gene sequences
(Elsevier B.V., 2020)In this study, we applied DNA barcoding tool for the molecular identification of horn snails Telescopium telescopium (Linnaeus, 1758) using mitochondrial cytochrome c oxidase I (mt-COI) gene and investigated their evolutionary ... -
Tectonics of the Deccan Trap: Focus on Indian Geoscientists� Contribution in the Last Four Years
(Indian National Science Academy, 2020)In the Deccan Trap, the west coast around Mumbai is presently designated as a �sheared margin� with nearly N-S trending strike-slip brittle shears. The eastern part of the Deccan trap shows prolific conjugate strike-slip ... -
Microbiome and ecology of a hot spring-microbialite system on the Trans-Himalayan Plateau
(Nature Research, 2020)Little is known about life in the boron-rich hot-springs of Trans-Himalayas. Here, we explore the geomicrobiology of a 4438-m-high spring which emanates ~70 °C-water from a boratic microbialite called Shivlinga. Due to low ... -
Biodegradation of seafood waste by seaweed-associated bacteria and application of seafood waste for ethanol production
(Academic Press, Elsevier, London, 2019)A huge quantity of seafood waste is generated from seafood restaurants, fish-processing industries, fish markets, and kitchens every day. The disposal of fish wastes in marine and fresh waters gives rise to an increasing ... -
Potential contribution to the nutrient pool due to the decomposition of Eichhornia crassipes under different salinity in an aquatic ecosystem-A laboratory study
(Elsevier B.V., 2020)The opening of Thannermukkom saltwater barriers during monsoon causes an Eichhornia crassipes infestation in Cochin backwater, Kerala-India; an annual occurrence. During the process, the plants are exposed to varying ... -
Tidal Triggering of the Harmonic Noise in Ocean-Bottom Seismometers
(Seismological Society of America (SSA), 2020)We observed a harmonic noise (HN) in DEPAS ocean-bottom seismometers (OBSs) data recorded from the Andaman-Nicobar region. The HN is characterized by sharp spectral peaks with a fundamental frequency and several overtones ... -
Tide Gauges
(CLIVAR/IOC-GOOS Indian Ocean Region Panel (IORP), 2019)Tide gauge measurements provide data for routine tidal predictions in ports as well as for extreme events such as storm surges and tsunamis. Along with satellite altimeter measurements, tide gauges also provide measurements ... -
Impact of 2004 co-seismic coastal uplift on the mangrove cover along the North Andaman Islands
(Springer, 2020)The December 2004 earthquake and the subsequent tsunami have incurred devastating impacts on vital habitats along the Indian coastal region, where few of them are irreversible. The earthquake has uplifted the northern ... -
Seasonal spreading and transport of buoyant plumes in the shelf off Kochi, South west coast of India- A modeling approach
(Nature Research, 2019)We investigated the seasonal spreading and transport of buoyant plume in the shelf off Kochi using Finite Volume Community Ocean Model (FVCOM). The modelled river plume typically consisted of an offshore bulge and a ... -
Functional and taxonomic (? and ?) diversity patterns of macrobenthic communities along a depth gradient (19-2639 m): A case study from the southern Indian continental margin
(Elsevier Ltd, 2020)Identifying the drivers that shape the biodiversity of a region is important to predict the response of ecosystems to environmental changes. Macrofaunal distribution pattern in the North Indian Ocean has so far been mainly ... -
An overview on agarophyte trade in India and need for policy interventions
(Springer Netherlands, 2019)Generally speaking, various seaweed resources, if properly managed, can be a renewable resource with the ability to be sustainably and commercially exploited on a global basis, according to the species available, for a ... -
Preliminary study on the response of marine fungoid protists, the thraustochytrids, to lipid extracts of diatoms
(Springer, 2020)Thraustochytrids are particle-associated protists, ubiquitous in the marine environment. They are known to display a negative relationship with phytoplankton cells but a positive one with their exudates and detritus. ... -
Degradation of tarballs using associated bacterial consortia
(Springer, 2020)Tarballs are semi-solid blobs of crude-oil formed in marine environment. Microbial degradation of tarballs is poorly understood, though there are indications that tarball-associated microbes can degrade recalcitrant ... -
