Microbial dolomite crusts from the carbonate platform off western India
(International Association of Sedimentologists, 2003)The occurrence of Late Pleistocene dolomite crusts that occur at 64 m depth on the carbonate platform off western India is documented. Dolomite is the most predominant mineral in the crusts. In thin section, the crust ... -
Microbial dynamics in a tropical monsoon influenced estuary: Elucidation through field observations and microcosm experiments on biofilms
(Elsevier, 2017)The changes that occur in biofilms reflect the influence of the environment. In a case study, the biofilms developed along a salinity gradient from marine to freshwater in a tropical monsoon influenced estuary (Zuari, west ... -
Microbial Ecosystem and Anthropogenic Impacts
(Springer, Singapore, 2020)Oceans are the most vulnerable sites for anthropogenic waste from domestic as well as industrial origin. Usually, marine ecosystems are exposed to most anthropogenic stressors ranging from sewage disposal to nuclear waste ... -
Microbial ecosystems of Antarctica. By W.F. Vincent
(NISCAIR, CSIR, 1990) -
Microbial exopolysaccharides: Effect on corrosion and partial chemical characterization
(Indian Institute of Science, 1999)Test panels of mild steel were deployed in the surface waters of the Dona Paula Bay over a period of 28 days. Biofilm material on mild steel panels was analyzed for biofilm biomass las organic carbon), exopolysaccharide ... -
Microbial extracellular polymeric substances in marine biogeochemical processes
(Indian National Science Academy, 2005)Microbial extracellular polymeric substances (EPS) are widely distributed in marine environments and are found in free dissolved form, colloids, discreet particles like TEP and/or associated with particulate matter, including ... -
Microbial flora and dehydrogenase activity of beaches
(CSIR-NISCAIR, 1977) -
Microbial heterotrophic metabolic rates constrain the microbial carbon pump
(The American Association for the Advancement of Science, 2011)The respiration of dissolved organic matter by heterotrophic bacteria and Archaea represents the largest sink in the global marine biological carbon cycle, an important constraint on organic carbon supply, and the major ... -
Microbial iron reduction and methane oxidation in subsurface sediments of the Arabian Sea
(Elsevier, 2015)Arabian Sea is one of the most productive regions of the world's ocean with seasonal upwelling and a characteristic oxygen minimum zone. It receives a continuous input of windborne iron-rich dust which possibly stimulates ... -
Microbial origin of the phosphorites of the western continental shelf of India
(Elsevier, 1988)Phosphatised algal nodules were recovered by dredging from the western continental shelf off Goa at depths ranging from 70 to 150 m. Energy dispersive X-ray analysis indicates that the phosphorus present in the algal nodules ... -
Microbial Safety of Fishery Products

Microbially mediated detrital food web: The link between mangroves and coastal aquatic animal communities
(M.S. Swaminathan Research Foundation, Madras, India, 1994)The importance of mangroves extends far beyond that which is offerEd. by their vegetation. In fact, mangroves constitute the driving force of the food web in coastal waters adjacent to them, in the form of detritus. Detritus, ... -
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 ... -
Microbiological studies in schirmacher oasis, Antarctica: Effect of temperature on bacterial populations
(1986)Seasonal and site wise variation in size and diversity of bacterial population was observed in Schirmacher Oasis, Antarctica. Prevailing soil temperature limited the distribution and abundance of groups of bacteria like ... -
Microbiological Studies in the Mandovi-Zuari River System
(CSIR-NISCAIR, 1981)Total heterotrophic and coliform bacteria were surveyed during October 1977 to September 1978 from 9 stations each along the rivers Mandovi and Zuari and 3 along the coast of Goa. Total heterotrophic population showed wide ... -
Microbiological Studies on the Sediments of Andaman Sea
(CSIR-NISCAIR, 1981)Total bacterial population in the sediments widely fluctuated from 2.1x 10 3 to 3.7 x 10 6. There was no significant correlation between organic carbon values and heterotrophic activity. Ratio of gram positive to gram ... -
Microbiology and biochemistry of placer rich beach sediment: Short-term response to small scale simulated mining
(Allied, India, 2005)In order to understand the influence of sand mining on the bacterial community of a placer rich beach ecosystem, a mechanical disturbance was simulated in Kalbadevi beach, Ratnagiri. Core samples from dune, berm, high tide, ... -
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 ... -
Microbiome of marine shallow-water hydrothermal vents
(CRC Press, Boca Raton, 2021)Marine hydrothermal vents are extreme environments in the ocean where tectonic activities are evidenced in the plate boundaries or mid-ocean ridges. Hot mineral-rich water coming out through the hydrothermal vent crevices ... -
Microdistribution of zooplankton in the neustonic realm of the eastern Arabian Sea during southwest monsoon
(Oxford and IBH, New Delhi, 1992)During the southwest monsoon season of 1987, the zooplankton distributions in the neustonic realm (upper 50 cm) of the eastern Arabian Sea were studied and compared with those in the water column. The upper microlayer ...
