Abstract: | Abstract The methoxylated aromatic acids vanillate and syringate supported the growth of Clostridium thermoaceticum and Clostridium thermoautotrophicum in an undefined culture medium (U); p -hydroxybenzoate or U did not support growth. Growth was proportional to the number of O -methyl residues on the aromatic ring and to the concentration of the methoxylated aromatic acid in U. Protein profiles, obtained by sodium dodecyl sulfate-polyacrylamide gel electrophoretic (SDS-PAGE) analysis of cell extracts from vanillate, syringate, methanol, and glucose cultures of C. thermoaceticum , indicated differential gene expression between O -methyl aromatic-, methanol- and glucose-grown cells. |
