文摘

Eight spore-forming lactic acid producing bacteria were isolated from tree barks in Thailand. They were identified as Sporolactobacillus nakayamae (Group I, three isolates), S. terrae (Group II, two isolates), S. kofuensis (Group III, one isolate) and S. inulinus (Group IV, two isolates) based on their phenotypic characteristics and 16S rRNA gene sequence analyses. Four isolates in Groups I and II produced DL lactic acid (89.60–114.61 g/L), while three isolates in Groups III and IV produced D-lactic acid (88.01–113.78 g/L). Isolate BK65-3 identified as S. inulinus produced the highest D-lactic acid concentrations (101.42 g/L), productivity (1.41 g/L/h), yields (84.52%) and optical purity of D-lactic acid (100%).
