    • Aerobic microbial communities in the sediments of a marine oxygen minimum zone 

      Bhattacharya, S.; Roy, C.; Mandal, Subhrangshu; Sarkar, J.; Rameez, M.J.; Mondal, N.; Mapder, T.; Chatterjee, Sumit; Pyne, P.; Alam, M.; Haldar, P.K.; Roy, R.; Fernandes, S.; Peketi, A.; Chakraborty, R.; Mazumdar, A.; Ghosh, W. (Oxford University Press (OUP), 2020)
      The ecology of aerobic microorganisms is never explored in marine oxygen minimum zone (OMZ) sediments. Here we reveal aerobic bacterial communities along ~3�m sediment-horizons of the eastern Arabian Sea OMZ. Sulfide-containing ...
    • Cryptic roles of tetrathionate in the sulfur cycle of marine sediments: microbial drivers and indicators 

      Subhrangshu, Mandal; Bhattacharya, S.; Roy, C.; Rameez, M.J.; Sarkar, J.; Mapder, T.; Fernandes, S.; Peketi, A.; Mazumdar, A.; Ghosh, W. (Copernicus Publications, European Geosciences Union, Germany, 2020)
      To explore the potential role of tetrathionate in the sedimentary sulfur cycle, population ecology of microorganisms capable of metabolizing this polythionate was revealed at 15-30 cm resolution along two, ~3 m long, cores ...
    • Enhanced carbon-sulfur cycling in the sediments of Arabian Sea oxygen minimum zone center 

      Fernandes, S.; Mazumdar, A.; Bhattacharya, S.; Peketi, A.; Mapder, T.; Roy, R.; Carvalho, M.A.; Roy, C.; Mahalakshmi, P.; DaSilva, R.; Rao, P.L.S.; Banik, S.K.; Ghosh, W. (Nature Publishing Group, 2018)
      Biogeochemistry of oxygen minimum zone (OMZ) sediments, which are characterized by high input of labile organic matter, have crucial bearings on the benthic biota, gas and metal fluxes across the sediment-water interface, ...
    • Geomicrobial dynamics of Trans-Himalayan sulfur-borax spring system reveals mesophilic bacteria's resilience to high heat 

      Roy, C.; Mondal, N.; Peketi, A.; Fernandes, S.; Mapder, T.; Volvoikar, S.P.; Haldar, P.K.; Nandi, N.; Bhattacharya, T.; Mazumdar, A.; Chakraborty, R.; Ghosh, W. (Springer, 2020)
      Geomicrobiology of sulfur-boron-dominated, neutral-pH hydrothermal systems was revealed in a Trans-Himalayan spring named Lotus Pond, located at 4436 m, in Puga Valley, Ladakh (India), where water boils at 85°C. Water ...
    • Microbiome and ecology of a hot spring-microbialite system on the Trans-Himalayan Plateau 

      Roy, C.; Rameez, M.J.; Haldar, P.K.; Peketi, A.; Mondal, N.; Bakshi, U.; Mapder, T.; Pyne, P.; Fernandes, S.; Bhattacharya, S.; Roy, R.; Mandal, Subhrangshu; ONeill, W.K.; Mazumdar, A.; Mukhopadhyay, S.K.; Mukherjee, Ambarish; Chakraborty, Ranadhir; Hallsworth, J.E.; Ghosh, Wriddhiman (Nature Research, 2020)
      Little is known about life in the boron-rich hot-springs of Trans-Himalayas. Here, we explore the geomicrobiology of a 4438-m-high spring which emanates ~70 °C-water from a boratic microbialite called Shivlinga. Due to low ...
