Marine actinobacteria showing phosphate-solubilizing efficiency in Chorao Island, Goa, India
(Springer, 2013)The occurrence and distribution of an actinobacteria group of bacteria capable of dissolving insoluble phosphates were investigated in this study in marine environments, especially in sediments of Chorao Island, Goa, India. ... -
Marinilabilia nitratireducens sp. nov., a lipolytic bacterium of the family Marinilabiliaceae isolated from marine solar saltern
(Springer, 2013)A Gram-negative, rod shaped, motile bacterium, was isolated from a marine solar saltern sample collected from Kakinada, India. Strain AK2 sup(T) was determined to be positive for nitrate reduction, catalase, Ala-Phe-Pro- ... -
Mariniradius saccharolyticus gen. nov., sp. nov., a member of the family Cyclobacteriaceae isolated from marine aquaculture pond water, and emended descriptions of the genus Aquiflexum and Aquiflexum balticum
(International Union of Microbiological Societies, 2013)A novel marine, Gram-stain-negative, oxidase- and catalase- positive, rod-shaped bacterium, designated strain AK6 sup(T), was isolated from marine aquaculture pond water collected in Andhra Pradesh, India. The fatty acids ... -
Metabolism of DMSP, DMS and DMSO by the cultivable bacterial community associated with the DMSP-producing dinoflagellate Scrippsiella trochoidea
(Springer, 2012)Bacterial species associated with the dimethylsulfoniopropionate (DMSP)-producing phytoplankton Scrippsiella trochoidea were cultured and identified, with the aim of establishing their ability to metabolise DMSP, dimethylsulfide ... -
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 ... -
Mixed response in bacterial and biochemical variables to simulated sand mining in placer-rich beach sediments, Ratnagiri, West coast of India
(Springer, 2012)The influence of mechanical disturbance of sediment-akin to small scale mining on bacterial community and biochemical variables was investigated at Kalbadevi beach, Ratnagiri, a placer-rich beach ecosystem which is a ... -
Mobilization of manganese by basalt associated Mn(II)-oxidizing bacteria from the Indian Ridge System
(Elsevier, 2014)The Indian Ridge System basalt bearing Mn-oxide coatings had todorokite as the major and birnesite as the minor mineral. We posit that microorganisms associated with these basalts participate in the oxidation of Mn and ... -
Molecular Characterization of 2-Chlorobiphenyl Degrading Stenotrophomonas maltophilia GS-103
(Springer, 2013)The catabolic potential of transformer oil contaminated soil bacteria in aerobic degradation of polychlorinated biphenyls (PCB) were assessed. Transformer oil contaminated soil sample was subjected to microcosm enrichment ... -
Molecular cross-talk between sponge host and associated microbes
(Springer, 2013)Marine organisms especially those that live sessile, as sponges, are well known to have specific relationships with a great variety of microorganisms including bacteria and fungi. As most simple metazoan phylum, the Porifera, ... -
Nitrate reducing activity pervades surface waters during upwelling.
(Elsevier, 2014)Nitrate reducing activity (NRA) is known to be mediated by microaerophilic to anaerobic bacteria and generally occurs in the sub-surface waters. However, we hypothesize that NRA could become prominent in the surface waters ... -
Nitrogen-limited mangrove ecosystems conserve N through dissimilatory nitrate reduction to ammonium
(Nature Publishing Group, 2012)Earlier observations in mangrove sediments of Goa, India have shown denitrification to be a major pathway for N loss However, percentage of total nitrate transformed through complete denitrification accounted for less than ... -
Observations on biofilm bacteria isolated from aluminium panels immersed in estuarine waters
(Herwood Academic, 1995)Microfouling biomass generally increased on aluminium panels immersed in the surface waters of a tropical estuary over a period of 30 d. A hundred bacterial colonies were randomly isolated, purified and morphologically, ... -
Occurrence and seasonal variation in distribution of fecal indicator bacteria in Tapi estuary along the West coast of India.
(NISCAIR, 2014)Distribution and occurrence of fecal indicator bacterial in nine different locations along the inner to coastal areas of Tapi estuary during three different seasons like, post-monsoon, pre-monsoon and monsoon were analyzed ... -
Oceanospirillum nioense sp. nov., a marine bacterium isolated from sediment sample of Palk bay, India
(Springer, 2013)A novel Gram-negative, spiral shaped, motile bacterium, designated strain NIO-S6T, was isolated from a sediment sample collected from Offshore Rameswaram, Tamilnadu, India. Strain NIO-S6 sup(T) was found to be positive for ... -
PCR screening for the surfactin (sfp) gene in marine Bacillus strains and its molecular characterization from Bacillus tequilensis NIOS11
(The Scientific and Technological Research Council of Turkey, 2013)The sfp gene responsible for surfactin production was screened from the DNA extracts of 37 Bacillus spp. whose identity was confirmed by 16S rRNA gene sequence analyses. PCR screening revealed amplification of sfp gene ... -
Penicillin-mediated changes in viable benthic diatom assemblages – insights about the relevance of bacteria across spatial and seasonal scales.
(CSIRO Publishing, 2014)Penicillin, a beta-lactam antibiotic, cannot affect diatoms directly but does so through bacteria. Its effects on viable benthic diatom assemblages in a tropical environment were evaluated across spatial (intertidal sandflat, ... -
Phenyltins in Surface Sediments of the Visakhapatnam Harbour, India
