Figure 4From: Influence of oxygen on NADH recycling and oxidative stress resistance systems in Lactobacillus panis PM1 Effect of external electron acceptors on end-product formation by L. panis PM1. End-product formation by L. panis PM1 cultured in mMRS containing either 24 mM citric acid (a) or 160 mM glycerol (b) as external electron acceptor under aerobic conditions. Samples for HPLC analysis were withdrawn from the cultures after 24 and 48 hours.Back to article page
