Isolation of a novel cyanophage infecting potentially bloom-forming Limnothrix sp
(Elsevier, 2022)A filamentous cyanobacterium, identified as Limnothrix sp. VL01, and a novel lytic cyanophage 'Φ L-VL01' that infects it, were isolated from a shallow freshwater lake located in Goa, India. Cyanophage-infected Limnothrix ... -
Isolation of multi-drug resistant Paenibacillus sp. from fertile soil: An imminent menace of spreading resistance.
(David Publishing, 2010)There are a good number of reports in the literature stating spread of resistance from normal soil flora to nosocomial microorganism through various ways. Similarly during the study of antimicrobial susceptibility pattern ... -
Isolation of peridininol, an anti-spasmodic carotenoid pigment, from Zoanthus sp.
(AP Akademi of Sciences, India, 2005)A C37 carotenoid pigment, peridininol, isolated from a marine Zoanthus sp. exhibited promising anti-spasmodic activity against nicotine and serotonin in in vitro studies using guinea pig ileum. Its purification and structure ... -
Isolation of stigmast-5,24-dien-3-ol from marine brown algae Sargassum tenerrimum and its antipredatory activity
(Royal Society of Chemistry, 2015)In recent years many sterols with potent biological activity have been identified from marine sources. Here we report the isolation of stigmast-5,24-dien-3-ol (fucosterol) as a major metabolite from the bioactive hexane-fraction ... -
Isolation, Biological Activities and Synthesis of Indoloquinoline Alkaloids: Cryptolepine, Isocryptolepine and Neocryptolepine
(Bentham Science, 2011)The tetracyclic heteroaromatic compounds cryptolepine, isocryptolepine and neocryptolepine are all naturally occurring indoloquinoline alkaloids isolated from the shrub Cryptolepis sanguinolenta and are important due to ... -
Isolation, optimization and characterization of selected Cyanophycean members
(NISCAIR, CSIR, 2010)Ten spp. of Cyanobacteria (non-heterocytous) were isolated from various marine habitats. Three bioactive potential forms, were observed for their optimization of growth, subjecting them to various concentrations of NaCl, ... -
Isolation, purification and characterization of xylanase produced by Arthrobacter sp. MTCC 5214 when grown in solid-state fermentation
(Elsevier, 2006)Thermoalkalophilic Arthrobacter sp. produced extracellular xylanase, when wheat bran, rice husk, rice bran and bagassae were used as carbon source under solid-state fermentation (SSF). The xylanase enzyme was isolated by ... -
Isostatic response of the Laccadive Ridge from admittance analysis of gravity and bathymetry data
(Elsevier, 2008)The Laccadive Ridge (L-R), trending roughly parallel to the west coast of India, is an intriguing segmentof the northernmost Chagos-Laccadive Ridge (C-L-R) system. Although crustal nature and isostatic response of the ... -
Isotopic composition of carbon and nitrogen of particulate organic matter in the Godavari estuary: Seasonality in sources and processes
(Springer, 2024)Rivers transport organic matter originating within the estuary and terrestrial sources to the coastal ocean. The seasonal variations in the magnitude of river discharge alter the sources of particulate organic matter (POM) ... -
Isotopic composition of nitrate and particulate organic matter in a pristine dam reservoir of western India: Implications for biogeochemical processes
(European Geosciences Union, 2017)Isotopic composition of nitrate (δ<sup>15</sup>N and δ<sup>18</sup>O) and particulate organic matter (POM; δ<sup>15</sup>N and δ<sup>13</sup>C) were measured in the Tillari Reservoir, located at the ... -
Isotopic composition of nitrate in the central Arabian Sea and eastern tropical North Pacific: A tracer for mixing and nitrogen cycles
(American Society of Limnology and Oceanography, 1998)The delta sup(15)N composition of nitrate and N sub(2) gas was measured in the eastern tropical North Pacific (ETNP) and central Arabian Sea (AS) suboxic regions. The delta sup(15)N of nitrate increased from 6 ppt at 2,500 ... -
