Abundance, viability and culturability of Antarctic bacteria
(Department of Ocean Development, New Delhi, India, 1999)
The viability of total number of bacteria decide the mineralisation rate in any ecosystem and ultimately the fertility of the region. This study aims at establishing the extent of viability in the standing stock of the ...
Marine microbiology: A glimpse of the strides in the Indian and the global arena
(Oxford and IBH, New Delhi, 2001)
The chapter reviews the development in marine microbiology in the national and international arena. It traces salient features from the pre-Zobell era to the mid 1990s. The studies in India have just made a beginning into ...
'Trade-off' in Antarctic bacteria: limnetic psychrotrophs concede multiple enzyme expressions for multiple metal resistance
(Springer, 2007)
The present study examines the metal and antibiotic resistant bacteria in ice and water from lakes east and west of the Indian base camp (Maitri) in Antarctica. The isolates from western and eastern lakes showed distinct ...
Distribution of baroduric, psychrotrophic and culturable nitrifying and denitrifying bacteria in the Central Indian Basin
(National Institute of Ocean Technology, 2004)
The abundance of baroduric, culturable nitrifying and denitrifying bacteria in the deep-sea cores of Central Indian Basin (CIB) at ca 5000 m depth was investigated. Analysis of 8 cores, sampled between 10 degrees 00 minutes ...
Metal and antibiotic-resistance in psychrotrophic bacteria from Antarctic marine waters
(Springer, 2006)
In the wake of the findings that Antarctic krills concentrate heavy metals at ppm level, (Yamamoto et al., 1987), the Antarctic waters from the Indian side were examined for the incidence of metal and antibiotic-resistant ...
A deep-sea bacterium with unique nitrifying property
(Indian Academy of Sciences, 2001)
Sediment cores collected from the Central Indian Basin (10°1¢–10°2¢S, 75°59¢–76°2¢E) harboured a high population of nitrifying bacteria which ranged from 103 to 107 cfu per gram dry weight. This high density could contribute ...
FiveS rRNA sequences and fatty acid profiles of colourless sulfur-oxidising bacteria
(Publ. and Inf. Dir., New Delhi, India, 1994)
Colourless sulfur-oxidising bacteria have been encountered extensively in the oxygen minimum layers of the Arabian Sea. These oligotrophs have been known to mediate nitrogen cycle reductively even under autotrophic conditions. ...
Nitrate and sulfate reducers-retrievable number of bacteria and their activities in Indian waters
(Oxford and IBH, New Delhi, 1992)
Culturable heterotrophic, nitrate reducing and sulfate reducing bacteria (HB, NRB and SRB) were enumerated from 25, 50, 100 and 200 m depths at 15 stations and their potential activities viz. Nitrate reducing (NRA) and ...
UV radiation and natural fluorescence linked primary production in Antarctic waters
(Marine Biological Association of India, 2001)
Primary productivity and chlorophyll values have been measured using an underwater profiling radiometer for the first time in the waters around Indian Antarctic Station (70°46'S & 11°44'E) in the summer of 1994. The profiles ...
Limno-tolerant bacteria govern nitrate concentration in Mandovi estuary, India
(Elsevier, 2009)
The spatial and temporal abundances of limno-tolerant and halo-tolerant bacteria were investigated in the tide-dominated Mandovi estuary along the west coast of India. These investigations were carried out in relation to ...
