The concentration of
L-arginine was measured using a Sykam S-433D amino acid analyzer (Sykam Co., Ltd., Germany) (Zhang et al., 2018 (
link)). Glucose concentrations were determined enzymatically by a bioanalyzer (SBA-40E, Shandong, China). Cell growth was determined by measuring the OD562 (1 OD562 = 0.375 g L
–1 dry cell weight) with a spectrophotometer (BG-XM496, Beijing, China). Nitrite concentrations were determined using Nitrite Content Assay Kit (Solarbio, Beijing, China). NADPH concentrations were determined using
NADPH Content Assay Kit (Solarbio, Beijing, China). ATP concentrations were determined using
ATP Content Assay Kit (Solarbio, Beijing, China). NADH concentrations were determined using NADH Content Assay Kit (Beyotime, Shanghai, China). All experiments were performed in triplicates, and data were represented as the mean ± standard deviation.
