A comparative study of coastal and clinical isolates of Pseudomonas aeruginosa
(Elsevier, 2015)Pseudomonas aeruginosa is a ubiquitous Gram-negative bacterium having a versatile metabolic potential and great ecological and clinical significance The geographical distribution of P aeruginosahas revealed the existence ... -
Abundance of bacterial and diatom fouling on various surfaces
(Indian National Science Academy, 1995)Abundance of bacterial and diatom fouling on aluminium, fibreglass and stainless steel were studied from Dona Paula waters of the Zuari Estuary. Both these forms were reversibly attached in large numbers to surfaces during ... -
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 ... -
Amino acid biogeochemistry and bacterial contribution to sediment organic matter along the western margin of the Bay of Bengal
(Elsevier, 2014)Six sediment cores collected from various water depths and sampling locations along the western margin of the Bay of Bengal (BOB) were investigated for the total hydrolysable amino acids (THAA) and d-amino acids (d-AA) to ... -
Anaerobic sulfide-oxidation in marine colorless sulfur-oxidizing bacteria
(Springer, 1997)Colorless sulfur-oxidizing bacteria are ubiquitous in Indian waters and have the ability to oxidize sulfide under anaerobic conditions. These bacteria can not only mediate the sulfur cycle oxidatively but also the nitrogen ... -
Arthrobacter enclensis sp. nov., isolated from sediment sample
(Springer, 2014)A novel bacterial strain designated as NIO-1008(T) was isolated from marine sediments sample in Chorao Island India. Cells of the strains were gram positive and non-motile, displayed a rod-coccus life cycle and formed cream ... -
Bacterial abundance and production in the central and eastern Arabian Sea
(Current Science Association, Bangalore, India, 1996)Seasonal and spatial variations in bacterial and picoplankton abundances and bacterial production (thymidine incorporation rates) were determined in the water column up to 150 m in several stations in the central and eastern ... -
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 the tropical estuarine and coastal waters of Goa, southwest coast of India
(Springer, 2003)Bacterial growth efficiency (BGE) is an index of organic carbon passing through bacteria in an aquatic system. BGE values of natural bacterioplankton assemblages were measured in tropical estuarine and adjacent coastal ... -
Bacteriological studies off Mangalore coast
(Indian Association for Limnology and Oceanography, 1982)Bacteriological studies of sediment and water in the near shore region off Mangalore showed that both limnotolerant and halotolerant bacteria were present. Significant inter-correlation (quantitative and qualitative) could ... -
Biofilm development on metal surfaces in tropical marine waters
(Discovery Publishing House, 2003)The immersion of solid surfaces in aquatic environment results in the rapid adsorption of dissolved organic matter, thereby conditioning the surfaces. A number of compounds including glycoproteins humic material and / or ... -
Biological and biochemical characterization of microfouling on aluminium panels placed in the Arabian Sea
(Indian Academy of Sciences, Bangalore, 1989)Microfouling biomass was higher in the shelf waters (< 200 m) as compared with the slope waters (> 200 m). Bacteria were first to colonize on the aluminium surfaces as irregular formations during the initial stages of ... -
Biological investigations of Indian phaeophyceae. 15, effect of antibacterial substance extracted from Sargassum johnstionii Setchell et Gardner collected from Okha, west coast of India on the growth of bacteria
(Seaweed Research and Utilization Association, 1996)Cruide either extract and two fractions from the lipid namely fraction A (unsaponifiable) and fraction B (saponifiable) were obtained from a dry sample of Sargassum johnstionii. From these extracts different concentrations ... -
Candidates for the development of consortia capable of petroleum hydrocarbon degradation in marine environment
(Fostering International Coop. Res., UK, 1995)Bacteria and yeasts from different niches of the tropical Indian waters were screened for their hydrocarbon degrading potential using 1% w/v in artificial seawater over a period of 6 days. About 20% of the 75 bacterial and ... -
Chemosynthesis in deep-sea red-clay: Linking concepts to probable martian life
(Planex, 2014)Chemosynthetic microbial activity could share similarities between Martian and Earth systems. The present study examined the patterns of distribution of chemosynthetic bacteria in the deep-sea red clay sediments of CIB ... -
Culturable epibacteria of the marine sponge Ircinia fusca: Temporal variations and their possible role in the epibacterial defense of the host
(Inter-Research, 2004)The influence of environmental changes on the epibacterial population of the marine sponge Ircinia fusca (Carter) was evaluated by using a bacterial culture-based approach. Sponge surface-associated bacteria were isolated, ... -
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 ... -
