In addition to sulfur-cycling prokaryotes, sediment enrichment cultures also yielded pure cultures of a lemon-shaped homoacetogenic bacterium closely related to species of Acetobacterium. Other fermentative isolates included two obligately anaerobic strains of a sugar-fermenting bacterium that were isolated from 9-meter Lake Fryxell water. These strains showed the highest degree of cold-adaptation of all isolates obtained in this study.Then, 10 ml of a 0.0054 M solution (0.2% in 20% H2SO4) of N, N- dimethyl-p- phenylenediamine sulfate was added to ... a reagent blank using a Beckman DU, Bausch and Lomb Spectronic 21, or Genesys Spectronic 20 spectrophotometer atanbsp;...
