Isolation of heterotrophic thiosulfate-oxidizing bacteria and their role in a conserved tidal flat in the Ariake Sea, Japan

April 2015

Intolerable sulfide emission was spotted at several areas in tidal flats of the Ariake Sea, Japan. Sulfide is naturally produced in tidal flats and rapidly oxidized by sulfur-oxidizing bacteria (SOB). This makes them important players in controlling released sulfide by sulfate-reducing bacteria. A part of SOB can grow heterotrophically and we isolated them from a conserved muddy tidal flat in the Midorikawa Estuary,...

Emperor Jahangir’s method of observation and approaches to investigation of Kashmir ecology: An appraisal of his ‘deep sense of sensitivity’ towards nature

March 2015

Historically speaking, ‘ecology’ today is an interdisciplinary as well as complex science. Modern ecology characterises more facts than possibly known. Any ecologist is today a specialist, with favourite and specialised questions. And hence, there are different sub-disciplines in ecology with its own set of concept(s) and all try to unify looking only at ‘ecology’. Moreover, it is now an...
