Abstract: Screening promising L. thermophiles with high productivity, high efficiency and strong adaptability are very important in lactic acid industry. For this purpose, 80MeV/u carbon ions were applied to irradiate L. thermophiles. After high-throughput screening, a mutant, named SRZ50, was obtained. Different carbon sources or nitrogen sources were provided to investigate carbon or nitrogen source utilization between mutant SRZ50 and wild type, and different fermentation periods were also chose to study fermentation… Show more

“…A wider interval between adjoining doses or a narrow range of irradiation doses may be one of the reasons for missing the phenomenon (Tang et al 2006;Wang et al 2011;Cheng et al 2016;Xie et al 2018). For a minority of studies reporting the Bsaddle-shaped^dose-survival curve in response to moderate-or high-energy HI (Jiang et al 2017;Hu et al 2017a), the combination of the particular sample conditions (containing thickness, density, ingredient, etc.) and radiation parameters (containing the dose, energy, ionic type, etc.)…”

“…Two strains of L. thermophiles and L. thermophiles SRZ50 were constructed by irradiating of 80 MeV/u carbon ions and then these strains were utilized for the consumption of different carbon sources (glucose or fructose as best) or nitrogen sources (yeast powder as best source) for enhanced l ‐(+)‐lactic acid production (23 g⋅L −1 ) and biomass compared to the wild‐type strain [66]. Engineered Synechococcus elongatus PCC7942 was constructed by the introduction of enzyme d ‐lactate dehydrogenase ( Ldh D) (from L. bulgaricus ATCC11842) enzyme, which had utilized an efficient light‐driven system in the production of d ‐lactic acid from carbon dioxide (CO 2 ) via reversion of its favored cofactor from NADH to NADPH [67].…”
