Transcription profiling of E. coli BL21, BL21/pOri1 and BL21/pOri2mutants

Project description:Transcription profiles in BL21, BL21/pOri1 and BL21/pOri2 were analysed using DNA microarray technology. BL21, BL21/pOri1 or BL21/pOri2 strains were cultured at chemostat status and harvested after the cultivation arrived steady status. Experiment Overall Design: BL21, BL21/pOri1 and BL21/pOri2 were cultured at the exponential growth status or at the same growth rate status, respectively. E. coli BL21, BL21/pOri1 and BL21/pOri2 RNAs were reverse-transcripted into cDNAs, The RNAs from the BL21, BL21/pOri1, BL21/pOri2 were labelled with biotin. The labelled cDNAs were mixed and then hybridized on the microarray slides. Experiments were repeated four times. Most of them have no significant difference comparing plasmid-carrying E. coli and plasmid-free E. coli

Transcriptomic response of the xylose-selective strain derived from E. coli BL21(DE3) growing on xylose or glucose

Project description:Different genetic engineering strategies have been proposed to obtain E. coli strains that selectively consume xylose. In this study, a previously reported strategy for obtaining a xylose-selective strain in E. coli K12 was applied to E. coli BL21 (DE3). While this approach resulted in the expected xylose-selective phenotype, a low xylose consumption rate was recorded when the strain was grown on a mixture of xylose and glucose. To enhance xylose consumption, a variant of the transcriptional activator XylR was expressed. The resulting strain not only exhibited an improved capacity to consume xylose but also slightly recovered the ability to consume glucose. The aim of the microarray analysis was to identify the transcriptional changes associated with glucose assimilation in the BL21(DE3) derived xylose-selective strain.

Transcriptomic differences between E. coli BL21 and K-12 MG1655 during n-heptanoic acid stress

Project description:Biosynthesis of carboxylic acids and fatty acids from renewable biomass is a key issue in biorefinery. However, their productivities are often limited due to various toxic effects of the products on the host organisms. Here, we have investigated the factors that influence tolerance of Escherichia coli to long chain carboxylic acid (e.g., n-heptanoic acid)-induced stress by using transcriptome analysis. The metabolic and genomic responses of E. coli BL21 and MG1655 strains with n-heptanoic acid indicated that acid stress is one of the major stresses, which might be generated by n-heptanoic acid in addition to the presumed solvent-like stress.

Microaerobic fermentation alters lactose metabolism in Escherichia coli

Project description:We report the effect of oxygenation state in lactose grown escherichia coli producing recombinant proteins. To shed more light on the mechanistic correlation between the uptake of lactose and dissolved oxygen, a comprehensive study has been undertaken with the E. coli BL21 (DE3) strain. Differences in consumption pattern of lactose, metabolites, biomass and product formation due to aerobiosis have been investigated. Transcriptomic profiling of metabolic changes due to aerobic process and microaerobic process during protein formation phase has been studied and the results provide a deeper understanding of protein production in E. coli BL21 (DE3) strains with lactose based promoter expression systems.This study also provides a scientific understanding of escherichia coli metabolism upon oxygen fluctuations.
