The relative contribution of propionate, and long-chain even-numbered fatty acids to the production of long-chain odd-numbered fatty acids in rumen bacteria.
1. The relative contribution of propionate, and long-chain even-numbered fatty acids to the production of long-chain odd-numbered fatty acids in six pure cultures of rumen bacteria were studied, using single and double isotope procedures. 2. ⋯ The incorporation of propionate into odd-numbered fatty acids was markedly reduced in the presence of palmitate, or stearate. 5. The significance of the operation of alpha-oxidation is discussed in relation to the energy conservation in rumen bacteria.
