As the most prevalent bacterial cause of human gastroenteritis, food-borne Campylobacter infections pose a serious threat to public health. Whole Genome Sequencing (WGS) is a tool providing quick and inexpensive approaches for analysis of food-borne pathogen epidemics. Here we report the WGS and annotation of a Campylobacter coli strain, FNW20G12, which was isolated from milk in the United States in 1997 and carries multidrug resistance. The draft genome of FNW20G12 (DDBJ/ENA/GenBank accession number LWIH00000000) contains 1, 855,435 bp (GC content 31.4%) with 1902 annotated coding regions, 48 RNAs and resistance to aminoglycoside, beta-lactams, tetracycline, as well as fluoroquinolones. There are very few genome reports of C. coli from dairy products with multidrug resistance. Here the draft genome of FNW20G12, a C. coli strain isolated from raw milk, is presented to aid in the epidemiology study of C. coli antimicrobial resistance and role in foodborne outbreak.

Phosphoenolpyruvate carboxylase encoded by ppc catalyzes the anaplerotic reaction of oxaloacetate in the TCA cycle in Escherichia coli. Deletion of ppc does not prevent the cells from replenishing oxaloacetate via the glyoxylate shunt, but the ppc-deletion strain almost did not grow on glucose. In the present study, we obtained evolved strains by deleting both ppc and mutS to increase the mutation rate and investigated the mechanisms for improving growth by analyzing the mutated genes.

The cytoplasmic membrane of bacteria is composed of a phospholipid bilayer made up of a diverse set of lipids. Phosphatidylglycerol (PG) is one of the principal constituents and its production is essential for growth in many bacteria. All the enzymes required for PG biogenesis in have been identified and characterized decades ago.

Desorption electrospray ionization mass spectrometry imaging (DESI-MSI) provides direct analytical readouts of small molecules that can be used to characterize the metabolic phenotypes of genetically engineered bacteria. In an effort to accelerate the time frame associated with the screening of mutant libraries, we have developed a high-throughput DESI-MSI analytical workflow implementing a single raster line-scan strategy that facilitates the collection of location-resolved molecular information from engineered strains on a subminute time scale. Evaluation of this "Fast-Pass" DESI-MSI phenotyping workflow on analytical standards demonstrated the capability of acquiring full metabolic profiling information with a throughput of ∼40 s per sample.

synthesizes aromatic amino acids (AAAs) through the common pathway to produce the precursor, chorismate, and the three terminal pathways to convert chorismate into Phe, Tyr, and Trp. also imports exogenous AAAs through five transporters. GcvB small RNA post-transcriptionally regulates more than 50 genes involved in amino acid uptake and biosynthesis in , but the full extent of GcvB regulon is still underestimated.
