Abstract
Desulfobacterium vacuolatum strain IbRM was able to grow using casamino acids as a source of carbon, energy and nitrogen. Growth was accompanied by utilization of several amino acids and sulfide production. Pro-line and glutamate were used preferentially and to the greatest extent. Glycine, serine and alanine were used more slowly and only after proline and glutamate were used. Isoleucine, valine, leucine and aspartate decrease was slowest and occurred in a linear fashion throughout the growth phase. Amino acids used from casamino acids, excluding aspartate, were also used as single carbon, energy and nitrogen sources. As a single amino acid, aspar-tate could only be used as a nitrogen source. Aspartate was not used as an electron acceptor. No growth occurred on any amino acid in the absence of sulfate. As single substrates, isoleucine, proline and glutamate were oxidized without formation of acetate and with molar yields of 13.1, 9.4 and 7.7 g mol –1 , respectively.
