Abstract

Lactic acid is a versatile, multi-functional organic monomer in various industries, creating worldwide demand. High titer lactic acid production was achieved by novel Bacillus amyloliquefaciens J2V2AA through sugarcane molasses fermentation up to 178 mg mL⁻¹. A metabolomics approach such as combined GC-MS and LC-MS was applied to elucidate the involvement of key metabolites in lactic acid production. The results revealed the participation of 58 known intra-cellular metabolites at various pathways in lactic acid production. Twenty-eight highly up-regulated and down-regulated metabolites were analyzed, and a schematic diagram of a possible lactic acid production pathway was proposed. The produced lactic acid was analyzed through FTIR, UV-Spectrum, and HPLC analysis.

揭示细胞内代谢物在以甘蔗糖蜜为基质的新型解淀粉芽孢杆菌产乳酸中的作用。

乳酸是一种多用途、多功能的有机单体，广泛应用于各个行业，在世界范围内都有广泛的需求。新型解淀粉芽孢杆菌J2V2AA通过甘蔗糖蜜发酵生产高滴度乳酸，产量为178 mg mL-1。代谢组学方法，如联合GC-MS和LC-MS，被用于阐明关键代谢物在乳酸生产中的参与。结果揭示了58种已知的细胞内代谢物参与乳酸产生的各种途径。分析了28种高度上调和下调的代谢物，并提出了可能的乳酸生成途径的示意图。通过红外光谱、紫外光谱和高效液相色谱对所得乳酸进行分析。

期刊介绍： Molecular Omics publishes high-quality research from across the -omics sciences. Topics include, but are not limited to: -omics studies to gain mechanistic insight into biological processes – for example, determining the mode of action of a drug or the basis of a particular phenotype, such as drought tolerance -omics studies for clinical applications with validation, such as finding biomarkers for diagnostics or potential new drug targets -omics studies looking at the sub-cellular make-up of cells – for example, the subcellular localisation of certain proteins or post-translational modifications or new imaging techniques -studies presenting new methods and tools to support omics studies, including new spectroscopic/chromatographic techniques, chip-based/array technologies and new classification/data analysis techniques. New methods should be proven and demonstrate an advance in the field. Molecular Omics only accepts articles of high importance and interest that provide significant new insight into important chemical or biological problems. This could be fundamental research that significantly increases understanding or research that demonstrates clear functional benefits. Papers reporting new results that could be routinely predicted, do not show a significant improvement over known research, or are of interest only to the specialist in the area are not suitable for publication in Molecular Omics.
