[Neutral and basic compounds present in gases produced by Clostridium sporogenes, Plectridium putrificum and Plectridium glycolicum cultured under vacuum in sodium thioglycolate glucose broth].

: The study of gases produced by Clostridium sporogenes, Plectridium putrificum et P. glycolicum cultured under vacuum in sodium thioglycolate glucose broth makes possible the detection of compounds not described before for these Bacteria, particularly methyl-2 butanal and methyl-3 butanal for P. glycolicum and thiacyclopropane in these 3 Bacteria. Thiacyclopropane is the result of the cyclization of mercapto-2 ethanol produced by the reduction of thioglycolic acid.
