Assemblage of benthic diatoms and culturable heterotrophs in shallow-water hydrothermal vent of the D. Joao de Castro Seamount, Azores in the Atlantic Ocean
(Current Science Association, India, 2008)The shallow-water hydrothermal vent of D. Joao de Castro Seamount in the North Atlantic, between the Azorean islands Sao Miguel and Terceira, is characterized by yellow and white zones which are distinct in physical and ... -
Autotrophic and heterotrophic characteristics in a polluted tropical estuarine complex
(Academic Press, 1995)Some species of microbial heterotrophic communities (14C glucose uptake and respiration; viable nad total bacterial numbers) and autotrophic communities (primary production rate, chlorophyll a, phytoplankton cell counts ... -
Bacterial abundance, communities and heterotrophic activities in the coastal waters off Tamil Nadu
(NISCAIR, CSIR, 1996)Culturable aerobic heterotrophic bacterial (CAHB) numbers, total direct counts (TDC), bacterial generic composition and uptake of labelled glucose by natural microbial assemblages were studied from a few selected coastal ... -
Bacterial contribution to mitigation of iron and manganese in mangrove sediments
(Elsevier, 2007)The Mandovi and Chapora, (Goa, India) are two tropical estuaries lying in close geographic proximity on the west coast of India. Seasonal changes in down core variation of Fe, Mn and Total Organic Carbon (TOC) in the ... -
Bacterial flora of pond reared Penaeus indicus (Milne Edwards)
(Oxford and IBH, 1998)The population size, generic diversity and potential to produce hydrolytic enzymes of heterotrophic bacteria associated with pond reared Penaeus indicus was worked out following standard bacteriological procedures. ... -
Bacterial growth efficiency in a tropical estuary: Seasonal variability subsidized by allochthonous carbon
(Springer, 2007)Bacterial growth efficiency (BGE) is a key factor in understanding bacterial influence on carbon flow in aquatic ecosystems. Intra-annual variability in BGE, and bacteria-mediated carbon flow in the tropical Mandovi and ... -
Benthic foraminifera as pollution indices in the marine environment of west coast of India
(Universita' degli Studi di Milano, 1984)Two ecosystems affected by acidic pollutants (Thana Creek, Bombay and inshore area of Trivandrum, Kerala) and two other ecosystems affected by alkaline pollutants (Cola Bay, Goa and inshore area of Karwar, Karnataka) were ... -
Culturable heterotrophic bacteria from the euphotic zone of the Indian Ocean ocean during the summer monsoon
(Elsevier, 1994)Cuturable heterotrophic bacterial counts (viable counts: VC) by surface plating on ZoBell medium and total bacterial counts (TC) by epifuorenscence microscopy were carried out in sea water off the southwest coast of India ... -
Distribution and species composition of planktonic luminous bacteria in the Arabian Sea
(CSIR-NISCAIR, 1987)Distribution of the total viable heterotrophic bacteria and the luminous bacteria in the neretic and oceanic waters of the west coast of India was studied. Counts of viable heterotrophs fluctuated widely, generally with a ... -
Experimental studies on Urea Degradation in Seawater
(Indian Association for Limnology and Oceanography, 1980)The rate of urea degradation in seawater was studied under various conditions and the kinetics of urea degradation was evaluated. Urea decomposition experiments showed that the rates and quantity of ammonium oxidation were ... -
Heterotrophic Bacterial populations in tropical Sandy Beaches
(Indian Association for Limnology and Oceanography, 1980)Distribution pattern of heterotrophic bacterial flora of three sandy beaches of the west coast of India was studied. The population in these beaches was microbiologically different. Population peaks of halotolerant and ... -
Mathematical modeling of the evolution of a simple biological system
(India Environment Portal, Centre for Science and Environment, 2013)As a part of teaching of physics it is common to record data on evolution of a physical system and then construct a mathematical model of the system. For example, movement of a simple pendulum can be recorded, and then a ... -
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 ... -
Seasonal variations in carbon biomass of bacteria, thraustochytrids and microzooplankton in the northern Arabian Sea
(Elsevier, 2005)As a part of the JGOFS-India Programme, abundance of heterotrophic bacteria (Hbac; 0-2000 m), thraustochytrids (0-2000 m), microzooplankton (0-200m occasionally up to 300 m) as well as bacterial growth rates (0-500 m) were ... -
Seasonal variations of nitrate reducing and denitrifying bacteria utilizing hexadecane in Mandovi estuary, Goa, West Coast of India
(CSIR-NISCAIR, 2013)Mandovi estuary has a prolific population of heterotrophic bacteria due to the influx of nutrients including nitrate and organic hydrocarbons. Seasonal sampling at various locations along the estuary was carried out to ... -
