Abstract
An anaerobic continuous culture study was made with Campylobacter spec. to determine growth yields under various growth conditions. The growth media contained 0.1% (w/v) yeast extract as carbon source. When grown in an aspartate-limited culture Ymaxasp was 4.6. Inclusion of formate in the culture medium hardly affected the true growth yield. The number of ATP equivalents generated in the fumarate-reductase system was 0.66 and the YmaxATP was 7.0. In the nitrate reduction with formate 1.7 ATP equivalents were generated, and a YmaxNO3- of 12.2 was observed. The true growth yield obtained with a mixture of lactate and aspartate was lower than that found with aspartate alone.
