Brevundimonas diminuta MTCC 8486, isolated from marine soil of coastal area of Trivandrum, Kerala, was used for biological removal of nitrate from ground water collected from Kar village of Pali district, Rajasthan. The organism was found to be resistance for nitrate up to 10,000 mg L(-1). The optimum growth conditions for biological removal of nitrate were established in batch culture. The effect of carbon sources on nitrate removal was investigated using mineral salt medium (MSM) containing… Expand

Genes and microbes impacting the geochemistry of arsenic mobilised aquifers in Bangladesh and Cambodia
TLDR
The goal of this work was to use a comprehensive suite of state-of-the-art molecular techniques in order to better constrain the relationship between indigenous microbial communities and the iron and arsenic mineral phases present in sediments at two wellcharacterised arsenic impacted aquifers in Bangladesh.

Factors Controlling Microbially Induced Desaturation and Precipitation (MIDP) via Denitrification during Continuous Flow
TLDR
Investigation of the effects of nitrate loading rate and input concentrations of acetate and calcium on the effectiveness of denitrification to promote microbially induced desaturation and precipitation (MIDP) supports that lower nitrateloading rates can be beneficial for MIDP although higher nitrates loading rates might be useful for some soil improvement applications.

Isolation of aluminum-tolerant bacteria capable of nitrogen removal in activated sludge.
TLDR
Results of this study provide more information about aluminum-resistant bacteria and laid the foundation for aluminum salt when it is simultaneously used for chemical precipitation. Expand
Moving bed biofilm reactor developed with special microbial seed for denitrification of high nitrate containing wastewater.
TLDR
Findings suggest that bench-scale MBBR developed with biofilm forming denitrifying microbial seed accelerated the denitrification process; therefore it is suggested as one of the best suitable and effective approach for removal of nitrate from wastewater. Expand
Microbial Community Structure and Arsenic Biogeochemistry in Two Arsenic-Impacted Aquifers in Bangladesh
TLDR
Findings suggest that direct As redox transformations are central to arsenic fate and transport and that there is a residual reactive pool of both As(V) and Fe(III) in deeper sediments that could be released by microbial respiration in response to hydrologic perturbation, such as increased groundwater pumping that introduces reactive organic carbon to depth.

Membrane bioreactors fed with different COD/N ratio wastewater: impacts on microbial community, microbial products, and membrane fouling
TLDR
Comparison of membrane filtration performance, microbial community, and microbial products under low temperature was carried out in anoxic/oxic (A/O) MBRs with COD/N ratios of 9.9 and 5.5; there was no doubt that an improvement of nitrogen removal under high C OD/N ratio was observed; however, severer membrane fouling was found compared to the MBR fed with low COD-N ratio wastewater.

Concepts and Methods to Access Novel Antibiotics from Actinomycetes
TLDR
Advanced cultivation methods, genomics- and metagenomics-based approaches, as well as modern metabolomics-inspired methods are highlighted to emphasise the interplay of different disciplines to improve access to novel natural products. Expand
Natural Bacterial Communities Serve as Quantitative Geochemical Biosensors
TLDR
It is shown that statistical analysis of DNA from natural microbial communities can be used to accurately identify environmental contaminants, including uranium and nitrate at a nuclear waste site, and the bacterial strains that are most useful for detecting oil and uranium are known to interact with these substrates.
