A semidefined medium based on Casamino Acids allowed Lactococcus lactis ATCC 19435 to grow in the presence of oxygen at a slow rate (0.015 h(-1)). Accumulation of H(2)O(2) in the culture prevented a higher growth rate. Addition of asparagine to the medium increased the growth rate, whereby H(2)O(2) accumulated only temporarily during the lag phase. H(2)O(2) is an inhibitor for several glycolytic enzymes, glyceraldehyde-3-phosphate dehydrogenase being the most sensitive. Strain ATCC 19435… CONTINUE READING
