The development of anaerobic enrichment cultures and measurements of the rates of methanogenesis, the turnover of 14C acetate and the degradation of substrates from sediment samples from Bratina Island
Entry ID: K141_1992_1994_NZ_1

Abstract: Life in ponds and tidal lagoons of the McMurdo Ice Shelf is dominated by benthic cyanobacterial mats. Anaerobic conditions occur beneath these productive mats. A study was conducted to investigate the degradation processes of biogeochemical cycles in the Ice Shelf ecosystem by the heterotrophic microbes that occur below the benthic mats, in particular how these organisms facilitate the degradation ...
