abstract：:Although nitrate stimulated the capacity of Clostridium thermoautotrophicum and Clostridium thermoaceticum to oxidize (utilize) substrates under heterotrophic conditions, it inhibited autotrophic H2-CO2-dependent growth. Under basal medium conditions, nitrate was also inhibitory to the use of one-carbon substrates (i....
