Efficient homofermentative L-(+)-lactic acid production from xylose by a novel lactic acid bacterium, Enterococcus mundtii QU 25.
نویسندگان
چکیده
Enterococcus mundtii QU 25, a newly isolated lactic acid bacterium, efficiently metabolized xylose into l-lactate. In batch fermentations, the strain produced 964 mM l-(+)-lactate from 691 mM xylose, with a yield of 1.41 mol/mol xylose consumed and an extremely high optical purity of ≥99.9% without acetate production.

Complete Genome Sequence of Enterococcus mundtii QU 25, an Efficient l-(+)-Lactic Acid-Producing Bacterium
Enterococcus mundtii QU 25, a non-dairy bacterial strain of ovine faecal origin, can ferment both cellobiose and xylose to produce l-lactic acid. The use of this strain is highly desirable for economical l-lactate production from renewable biomass substrates. Genome sequence determination is necessary for the genetic improvement of this strain. We report the complete genome sequence of strain Q...
متن کاملHomofermentative production of optically pure L-lactic acid from xylose by genetically engineered Escherichia coli B
BACKGROUND Polylactic acid (PLA), a biodegradable polymer, has the potential to replace (at least partially) traditional petroleum-based plastics, minimizing "white pollution". However, cost-effective production of optically pure L-lactic acid is needed to achieve the full potential of PLA. Currently, starch-based glucose is used for L-lactic acid fermentation by lactic acid bacteria. Due to it...
متن کاملProduction of lactic acid using a new homofermentative Enterococcus faecalis isolate
Lactic acid is an intermediate-volume specialty chemical for a wide range of food and industrial applications such as pharmaceuticals, cosmetics and chemical syntheses. Although lactic acid production has been well documented, improved production parameters that lead to reduced production costs are always of interest in industrial developments. In this study, we describe the production of lacti...
متن کاملPhenotypic and genotypic diversity of dominant lactic acid bacteria isolated from traditional yoghurts produced by tribes of Iran
Morphological, biochemical and molecular characteristics were studied to identify dominant lactic acid bacteria (LAB), isolated from traditional yoghurts produced by tribes of Iran. From 60 yoghurt samples, a total of 137 LAB isolates were determined, in which 66 and 71 were identified as lactic acid cocci and bacilli, respectively. Biochemical tests showed the occurrence of 9.76% mesophilic ho...
متن کاملDraft Genome Sequence of a New Homofermentative, Lactic Acid-Producing Enterococcus faecalis Isolate, CBRD01
We report here the draft genome sequence of the novel homofermentative Enterococcus faecalis isolate CBRD01, which is capable of high lactic acid productivity and yields, with minimal nutritional requirements. The genome is 2.8 Mbp, with 37% G+C, and contains genes for two lactate dehydrogenase (LDH) enzymes found in related organisms.
