TL;DR
Two new mesophilic, sporeforming, gram-positive, strictly anaerobic, rod-shaped bacteria were isolated which utilized betaine in the Stickland reaction.
Abstract
Two new mesophilic, sporeforming, gram-positive, strictly anaerobic, rod-shaped bacteria were isolated which utilized betaine in the Stickland reaction. Strain M1 was obtained from pasteurized hypersaline sediments. Cells were motile rods and formed spherical terminal spores. Betaine was used with hydrogen and several amino acids as electron donors. In addition, several carbohydrates served as substrates. Growth required 1.5% NaCl with an optimum at 6.0% NaCl. The guanine plus cytosine content of the DNA was 26.9%. This strain is described as a new species, Clostridium halophilum. Strain W6 was isolated from marine sediments. Cells were motile rods and formed ovoid, subterminal spores. Betaine was used with hydrogen and several amino acids as electron donors. Carbohydrates were not fermented. Growth optimum was at 1.0% NaCl. The guanine plus cytosine content of the DNA was 26.1%. This strain is described as a new species, Clostridium litorale.

The GC content of highly purified DNA samples can be estimated from their thermal denaturation temperatures, employing small amounts of DNA, and a recent interesting observation is that the supercoiled component of polyoma DNA has a Tm which is 17° higher than the circular, nonsupercoiled or linear polyoma components.
