a Microbial growth (OD600), b mannitol, c glycerol, and d 1,3-PDO concentrations of KMK-23M (filled circle), KMK-46 (empty circle), and KMY (filled reversed triangle) strains in flask culture. e Comparison of 1,3-PDO production (g L−1) and its molar yield (mol mol−1 glycerol) between KMK-23M and KMY strains during 24 h. Bars represent titer and diamond-shaped dot represent yields. f Batch fermentation results of KMY strain with the concentrations of mannitol (filled circle) and glycerol (empty circle), 1,3-PDO (filled reversed triangle), and OD600 (empty triangle)
