Discovery of cytotoxic natural products from Red Sea sponges: Structure and synthesis
(Elsevier Masson s.r.l., 2021)Marine ecosystem continues to produce a great wealth of molecules endowed with cytotoxic activity towards a large panel of tumor cells. Marine sponges, apparently defenseless organisms are endowed through evolution with a ... -
Overview on Microbial Enzymatic Production of Algal Oligosaccharides for Nutraceutical Applications
(Springer, 2021)Global requirement for algal foods is increasing, as they are progressively consumed for its nutrition and health. Macroalgae is a proven source of metabolites, proteins, pigments, bioactive compounds, and algal polysaccharides. ... -
Ruthenium(II)-catalyzed synthesis of 2-arylbenzimidazole and 2-arylbenzothiazole in water
(Springer, 2021)Benzimidazoles/benzothiazoles are heterocyclic compounds which contain a five membered heteroatom and a benzene ring. They constitute a crucial structural unit of numerous bioactive compounds and natural products. Since ... -
Ecological and Biotechnological Aspects of Pigmented Microbes: A Way Forward in Development of Food and Pharmaceutical Grade Pigments
(MDPI AG, 2021)Microbial pigments play multiple roles in the ecosystem construction, survival, and fitness of all kinds of organisms. Considerably, microbial (bacteria, fungi, yeast, and microalgae) pigments offer a wide array of food, ... -
The world's largest coastal deoxygenation zone is not anthropogenically driven
(IOP Publishing, 2021)The growing number of oxygen-deficient coastal zones around the world and their impacts on marine life has always been a controversial issue as their development is largely attributed to anthropogenic activities which can ... -
Introduction (to book: Air Pollution and Its Complications: From the Regional to the Global Scale)
(Springer International Publishing, Cham, Switzerland, 2021)This book provides an overview of the fundamental concept of air pollution, emission sources of air pollutants and their transportation. First, the book presents a brief background on air pollution and its emission sources, ... -
Bacterial diversity associated with a newly described bioeroding sponge, Cliona thomasi, from the coral reefs on the West Coast of India
(Springer, 2021)The bacterial diversity associated with eroding sponges belonging to the Cliona viridis species complex is scarcely known. Cliona thomasi described from the West Coast of India is a new introduction to the viridis species ... -
Rock magnetic evidence of tectonic control on the sedimentation and diagenesis in the Andaman Sea over ~1 million years
(Elsevier, 2021)We evaluate the sedimentary (magnetic, mineralogical, geochemical, grain size) records of a long sediment core (NGHP-01-17 A) to elucidate the tectonic control on the sedimentation and diagenesis in the Andaman Sea (AS) ... -
Isolation and Identification of Tyrosinase Inhibitors from Marine Algae Enteromorpha sp
(Bentham Science Publishers, 2021)The extract of marine green algae Enteromorpha sp. was evaluated in vitro for inhibitory activity against mushroom tyrosinase enzyme. The principle active agents i.e. coumarin; 4-hydroxycoumarin (1) and two sterols; ... -
Evaluating the Bacterial Diversity from the Southwest Coast of India Using Fatty Acid Methyl Ester Profiles
(Springer, 2021)The fatty acid composition of bacterial isolates remains stable under standardized culture conditions, which makes it a useful taxonomic marker. The present study aims to characterize the diversity and quantity of fatty ... -
A Spatial Ecological Study Based on Benthic Foraminifera off Central West Coast of India: An Approach through Cluster Analysis with Special Reference to Oxygen Minimum Zone
(Springer, 2021)Fifty-two surface samples collected from a depth range between 15 and 3300�m from the Vijaydurg-Karwar sector off the central west coast of India were analyzed for benthic foraminifera. A total of 386 benthic foraminifera ... -
Controls of contrasting provenance and fractionation on the sediment magnetic records from the Bay of Bengal
(Elsevier, 2021)We present the results of rock magnetic, granulometric, microscopy and mineralogical analyses of shelf sediments off Krishna, Godavari, and Mahanadi Rivers, Bay of Bengal. The aim of the study was to assess the influence ... -
The maxima in northerly wind speeds and wave heights over the Arabian Sea, the Arabian/Persian Gulf and the Red Sea derived from 40 years of ERA5 data
(Springer, 2021)Recent studies point out the importance of northerly winds and waves in the Arabian Sea, especially those due to shamal and makran events in addition to the northeast monsoon system. We have analyzed climatology and trends ... -
The first record of the genus Lamellibrachia (Siboglinidae) tubeworm along with associated organisms in a chemosynthetic ecosystem from the Indian Ocean: A report from the Cauvery-Mannar Basin
(Springer Science and Business Media LLC, 2021)Here, we report for the first time, the genus Lamellibrachia tubeworm and associated chemosynthetic ecosystem from a cold-seep site in the Indian Ocean. The discovery of cold-seep was made off the Cauvery-Mannar Basin ... -
Ocean wave dynamics in the coastal area of the central west coast of India and its variability
(Elsevier, 2021)Examined the spatial and temporal changes in the wave spectra using waves measured in the coastal area at two locations for three years. Long-term variability is examined with ERA5 reanalysis data. The annual average wave ... -
Identification of wave systems in the multimodal sea state along the Indian shelf seas
(Springer, 2021)The coexistence of multiple wave systems generated locally and by remote storms is common in the ocean and its quantification is required in the design of marine facilities. This study identifies the multimodal sea states ... -
