th-cmuir.6653943832-687372020-06-10T07:12:27Z Feasibility Study for D-Lactic Acid Production from Thai Rice by Leuconostoc pseudomesenteroides TC49 and D-Lactic Acid Purification Tasneem Chemama Chayakorn Pumas Yingmanee Tragoolpua Narumol Thongwai Narumol Thongwai - Department of Biology Faculty of Science Chiang Mai University Chiang Mai Journal of Science Two enantiomers of lactic acid, D- and L-forms, are naturally produced by lactic acid bacteria. Generally, L-lactic acid is more abundant than D-lactic acid. Both forms have been importantly used as monomers in bio-plastic industry. In this study, total of 251 lactic acid bacterial strains were isolated and screened from samples collected in southern and northern Thailand. Among these bacteria, only 7 isolates produced D-lactic acid with optical purity ranging from 96.2 to 99.7%. The isolate TC49, identified as Leuconostoc pseudomesenteroides, produced the highest D-lactic acid and was selected for further investigation. When Thai broken rice was used as a raw material for D-lactic acid fermentation by the selected strain, D-lactic acid yield and productivity were 93 ± 0.03 g/l and 1.29 g/l/h, respectively, under the optimal conditions. Upon further recovery and purification by the ultrasonic extraction process, D-lactic acid obtained was 99% optical purity and was structurally examined by 1H-NMR determination. The results indicated the high potential of Leu. pseudomesenteroides TC49 as a D-lactic acid producing strain using rice as a raw material. 2020-06-10T07:12:27Z 2020-06-10T07:12:27Z 2020 Chiang Mai Journal of Science 47,3 (May 2020), p.403-417 2465-3845 https://epg.science.cmu.ac.th/ejournal/dl.php?journal_id=10913 http://cmuir.cmu.ac.th/jspui/handle/6653943832/68737 Eng Faculty of Science, Chiang Mai University |
