BACKGROUND To demonstrate the noninferiority of capecitabine plus oxaliplatin (XELOX) versus 5-fluorouracil/folinic acid and oxaliplatin (FOLFOX-4) as second-line therapy in patients with metastatic colorectal cancer after prior irinotecan-based chemotherapy. PATIENTS AND METHODS A total of 627 patients were randomly assigned to receive XELOX (n = 313) or… (More)
Leuconostoc citreum is a key microorganism in fermented foods of plant origin. Here we report the draft genome sequence for three strains of Leuconostoc citreum, LBAE C10, LBAE C11, and LBAE E16, which have been isolated from traditional French wheat sourdoughs.
Microorganisms extensively reorganize gene expression to adjust growth rate to changes in growth conditions. At the genomic scale, we measured the contribution of both transcription and transcript stability to regulating messenger RNA (mRNA) concentration in Escherichia coli. Transcriptional control was the dominant regulatory process. Between growth rates… (More)
BACKGROUND The metagenomic analysis of gut microbiomes has emerged as a powerful strategy for the identification of biomass-degrading enzymes, which will be no doubt useful for the development of advanced biorefining processes. In the present study, we have performed a functional metagenomic analysis on comb and gut microbiomes associated with the… (More)
The diversity of nine dairy strains of Lactococcus lactis subsp. lactis in fermented milk was investigated by both genotypic and phenotypic analyses. Pulsed-field gel electrophoresis and multilocus sequence typing were used to establish an integrated genotypic classification. This classification was coherent with discrimination of the L. lactis subsp.… (More)
Leuconostoc citreum belongs to the group of lactic acid bacteria and plays an important role in fermented foods of plant origin. Here, we report the complete genome of the Leuconostoc citreum strain NRRL B-742, isolated in 1954 for its capacity to produce dextran.
Asymmetrical flow field flow fractionation (AF4) has proven to be a very powerful and quantitative method for the determination of the macromolecular structure of high molar mass branched biopolymers, when coupled with multi-angle laser light scattering (MALLS). This work describes a detailed investigation of the macromolecular structure of native glycogens… (More)
Weissella confusa is a rod-shaped heterofermentative lactic acid bacterium from the family of Leuconostocaceae. Here we report the draft genome sequence of the strain W. confusa LBAE C39-2 isolated from a traditional French wheat sourdough.
To implement a protein engineering strategy for the improvement of enzyme performance on biomass, a straightforward, robust high-throughput method was devised and tested with recombinant GH11 xylanase as acting on wheat straw. The method requires automated liquid handling equipment, but avoids the need for specialized milling and powder weighing devices and… (More)
Experimental design and Response Surface Methodology (RSM) were used to optimize the production of ∆N123-GBD-CD2, an α-(1 → 2) branching sucrase previously reported as mainly produced in inclusion bodies. The ∆N123-GBD-CD2 encoding gene was cloned into two expression vectors in fusion with 6xHis tag or Strep tag II encoding sequences at 5′ and 3′ ends of… (More)
