Distribution of Bowen ratio over the north Indian Ocean
(India Meteorological Department, 1986)The monthly averages of Bowen ratio over the north Indian Ocean have been computed Three typical situations in the months of January May and September are taken for the present study Month to month differences in the Bowen ... -
The Lignin-Degrading Enzyme, Laccase from Marine Fungi : Biochemical and Molecular Approaches
(2008)The object of the present study was to isolate and identify obligate marine or marine-derived fungi that were hyper-laccase producers. The laccase from the selected marine-derived fungus was to be characterized and its ... -
Pigment and amylase production in Penicillium sp NIOM-02 and its radical scavenging activity
(Institute of Food Science and Technology, 2009)Penicillium sp NIOM-02 was isolated from the marine sediment, produced red pigment. The pigment extracted from this fungus scavenged 2, 2-diphenyl-1-pycrylhydrazyl (DPPH) radical. Penicillium sp NIOM-02 grown in media ... -
Microbially mediated redox transformations of manganese (II) along with some other trace elements: a study from Antarctic lakes
(Springer, 2009)The significance of freshwater systems in global manganese cycles is well appreciated. Yet, the polar systems, which encompass the largest freshwater repository in the world, have been least studied for their role in ... -
Effects and interactions of medium components on laccase from a marine-derived fungus using response surface methodology
(Molecular Diversity Preservation International, 2009)The effects of various synthetic medium components and their interactions with each other ultimately impact laccase production in fungi. This was studied using a laccase-hyper-producing marine-derived basidiomycete, Cerrena ... -
Composition of macrobenthos from the central Indian Ocean Basin
(Indian Academy of Sciences, 2009)The deep sea is well known for its high faunal diversity. But the current interest in its abundant polymetallic nodules, poses a threat to the little known benthic organisms surviving in this unique environment. The present ... -
Hydrothermal alteration studies of gabbros from northern central Indian ridge and their geodynamic implications
(Indian Academy of Sciences, 2009)Mylonitic gabbro and altered gabbro were recovered from off-axis high and corner high locations at ridge-transform intersection, adjacent to Vityaz transform fault of the slow spreading (32-35 mm/yr, full spreading) Northern ... -
Structural studies and antimicrobial properties of norcembrane diterpenoid from an Indian soft coral Sinularia inelegans Tixier-Durivault
(Indian Academy of Sciences, 2009)Two metabolites featuring norcembranoid diterpene skeleton have been isolated from chloroform extract of soft coral of the genus sinularia, which was collected from the southern coast of India. The structures of the ... -
Multi-beam backscatter image data processing techniques employed to EM 1002 system
(CUSAT, 2009)Application of multi-beam bathymetric data provides interesting seafloor features. Besides obtaining bathymetric data for seabed characterization backscatter data is also important. However, use of raw multi-beam backscatter ... -
CO2 supersaturation and net heterotrophy in a tropical estuary (Cochin, India): Influence of anthropogenic effect - Carbon dynamics in tropical estuary
(Springer, 2009)Carbon biogeochemistry of a tropical ecosystem (The Cochin Estuary, India) undergoing increased human intervention was studied during February (premonsoon), April (early monsoon) and September (monsoon) 2005. The Cochin ... -
A one year comparison of radar and pressure tide gauge at Goa, west coast of India
(CUSAT, 2009)At many locations absolute pressure gauges are used to obtain sea level data. Therefore, knowledge of the other physical processes which effect the sea level measurements at the coast is very important to insert the required ... -
Water soluble (Eta sup (6) - arene) ruthenium (II) complexes incorporating marine derived bioligand: Synthesis, spectral and structural studies
(Elsevier, 2009)A series of water soluble compounds of general formula [{(Eta sup(6)-arene)Ru(HMP)Cl}], [Eta sup(6)-arene = Eta sup(6)-cymene (1), eta sup(6)-HMB (2), eta sup(6)-C sub(6)H sub(6) (3); HMP = 5-hydroxy-2-(hydroxymethyl)-4-pyrone] ... -
Influence of river discharge on plankton metabolic rates in the tropical monsoon driven Godavari estuary, India
(Elsevier, 2009)To examine the influence of river discharge on plankton metabolic balance in a monsoon driven tropical estuary, daily variations in physico-chemical and nutrients characteristics were studied over a period of 15 months ... -
Time-dependence of salinity in monsoonal estuaries
(Elsevier, 2009)The theories and classification schemes commonly used for understanding estuarine dynamics often refer to a steady state of the estuary in which the salinity field is time-independent. In this state salinity-ingress into ... -
Polychaete diversity and its relevance in the rapid environmental assessment of Mumbai Port
(Current Science Association, 2009)The diversity and spatial patterns of polychaetes, a proven proxy for environmental assessment studies, were studied in 28 stations covering subtidal and intertidal segments as well as bunders and docks of the Mumbai Port. ... -
Impact of offshore placer mining experiments (PLAMEX) on the sediment size and heavy minerals
(Current Science Association, 2009)Two offshore placer mining experiments (PLAMEX) were conducted using submersible pumps specially designed by Central Mechanical Engineering Research Institute (CMERI), Durgapur (India) at 8 m water depth in Kalbadevi Bay ... -
A thermostable metal-tolerant laccase with bioremediation potential from a marine-derived fungus
(Springer, 2009)Laccase, an oxidoreductive enzyme, is important in bioremediation. Although marine fungi are potential sources of enzymes for industrial applications, they have been inadequately explored. The fungus MTCC 5159, isolated ... -
Tidal asymmetry in the Mandovi and Zuari estuaries, the West Coast of India
(Coastal Education and Reserch Foundation, 2009)Harmonic analysis of the observed and simulated tides in the Mandovi and Zuari estuaries along the west coast of India was carried out. Tidal constituents derived from this process were analyzed to study the tidal asymmetry ... -
