Figure 3From: Early adaptation to oxygen is key to the industrially important traits of Lactococcus lactis ssp. cremoris during milk fermentationThe pyruvate metabolism of Lactococcus lactis . ldh: gene coding for the lactate dehydrogenase; pdhA-D: genes coding for the pyruvate dehydrogenase complex; pfl: gene coding for pyruvate formate-lyase; adhE: gene coding for the acetaldehyde dehydrogenase; adhA: gene coding for the alcohol dehydrogenase; pta: gene coding for the phosphotransacetylase; ackA: gene coding for the acetate kinase, als: gene coding for catabolic and anabolic 2-acetolactate synthase; aldB-C: gene coding for the acetolactate decarboxylase; butA: gene coding for the diacetyl reductase; butB: gene coding for the acetoin reductase; noxE: gene coding for the NADH oxidase (NOX). Adapted from Oliveira et al.[29]. The blue area represents pathways up-regulated in O2 condition, and the yellow area represents pathways up-regulated in N2 condition.Back to article page
