Temporal bacterial diversity and detection of putative methanotrophs in surface mats of Lonar crater lake.

The phylogenetic diversity of bacterial communities in microbial mats of two different seasons from saline and hyperalkaline Lonar Lake was investigated using 16S rRNA gene library analysis. Arthrospira (Cyanobacteria) related clones (>80% of total clones) dominated libraries of both the seasons. Clear differences were found in both the seasons as the operational taxonomic units (OTUs) related to Fusibacter (LAI-1 and LAI-59) and Tindallia magadiensis (LAI-27) found in post-monsoon were not found in the pre-monsoon library.

Electricity generation using chocolate industry wastewater and its treatment in activated sludge based microbial fuel cell and analysis of developed microbial community in the anode chamber.

Feasibility of using chocolate industry wastewater as a substrate for electricity generation using activated sludge as a source of microorganisms was investigated in two-chambered microbial fuel cell. The maximum current generated with membrane and salt bridge MFCs was 3.02 and 2.

Phylogenetic analysis of methanogenic enrichment cultures obtained from Lonar Lake in India: isolation of Methanocalculus sp. and Methanoculleus sp.

The diversity of methanogenic archaea in enrichment cultures established from the sediments of Lonar Lake (India), a soda lake having pH approximately 10, was investigated using 16S rDNA molecular phylogenetic approach. Methanogenic enrichment cultures were developed in a medium that simulated conditions of soda lake with three different substrates viz., H(2):CO(2), sodium acetate, and trimethylamine (TMA), at alkaline pH.

Molecular analyses of microbial diversity associated with the Lonar soda lake in India: an impact crater in a basalt area.

The prokaryotic diversity associated with an Indian soda lake (Lonar Crater Lake) located in a basaltic soil area was investigated using a culture-independent approach. Community DNA was extracted directly from four sediment samples obtained by coring to depths of 10-20 cm. Small subunit rRNA genes (16S rDNA) were amplified by PCR using primers specific to the domains Bacteria and Archaea.
