Project description:Purpose： The goal of this study is compare the effect of glnA gene in curdlan synthesis in Agrobacterium sp. CGMCC 11546. methods: The transcriptional and metabolomics analysis the function of glnA in Agrobacterium sp. CGMCC 11546. Results: The transcriptional and metabolomics showed that the decrease of curdlan production in the ΔglnA mutants may be caused by the insufficient supply of energy ATP conclusion: glnA play an important role in curdlan synthesis in Agrobacterium sp. CGMCC 11546

Project description:Purpose: The goal of this study is compare the effect of MetH and MetZ gene in curdlan synthesis in Agrobacterium sp. CGMCC 11546. methods: The transcriptional and metabolomics analysis the function of metH and metZ in Agrobacterium sp. CGMCC 11546. Results: The transcriptional and metabolomics showed that the decrease of curdlan production in the ΔmetH and ΔmetZ mutants may be caused by the insufficient supply of energy ATP conclusion: MetH and MetZ play an important role in curdlan synthesis in Agrobacterium sp. CGMCC 11546
Project description:We report the analysis of differentially gene expression after 7 hours and 24 hours fermentation of curdlan in Agrobacterium sp. CGMCC 11546.
Project description:Proteomic Analysis. The proteomic expression of CGMCC 6315 under different nutrient concentration conditions was investigated by isobaric tags for relative and absolute quantitation (iTRAQ)-based quantitative proteomics. The CGMCC 6315 was cultured in LB broth and 1/15LB broth as described above, after which the strains were collected by centrifugation at 10,000× g for 10 min at 4°C. Protein extraction, digestion, iTRAQ labeling and peptide fractionation were performed using the protocol described by Jin et al. 29. Protein identification was conducted using a LC-20AD nano-HPLC instrument (Shimadzu, Kyoto, Japan) equipped with a Q EXACTIVE tandem mass spectrometer (Thermo Fisher Scientific, San Jose, CA, USA) for data-dependent acquisition detection by nano-electrospray ionization. The raw MS/MS data were converted into MGF format by the thermo scientific tool Proteome Discoverer, and the exported MGF files were searched using Mascot (version 2.3.02) against the selected database containing 7546 CGMCC 6315 coding genes. The IQuant software was used for quantitative analysis of the labeled peptides with isobaric tags. Fold changes of >1.7 with p-values <0.05 were used as a cut off for differentially regulated proteins.
Project description:We conducted transcriptome analysis of Komagataeibacter europaeus CGMCC 20445 samples under different acidity conditions to elucidate the changes in differentially expressed genes throughout the fermentation process.
