Amino acid supplementation for enhancing recombinant protein production in E. coli

Project description:Amino acid starvation during recombinant protein production (RPP) induces metabolic stress to cellular host which results in reduced productivity of the recombinant bioprocess. In present study, supplementation of amino acids in a chemically defined medium showed several folds increase in recombinant product titers in E. coli BL21 DE3 strain. To understand, the effect of amino acid supplementation in alleviating cellular stress during RPP a deep insight of cellular physiology must be studied. Here, we performed transcriptomic analysis of E. coli expressing a recombinant protein in two different conditions: with (5 mM of all 20 amino acids) as test and without supplementation of amino acids as control. RNA-seq data revealed downregulation of several genes associated with stress in test culture confirming the critical role of amino acids supplementation in improving RPP.

Impact of Stringent Stress Response and Amino Acid Supplementation on Recombinant Protein Production in Escherichia coli

Project description:Metabolic burden can only be understood if changes in gene expression patterns and corresponding proteins/metabolites of the non-recombinant (WT) host were investigated along with recombinant under similar growth conditions. Intriguing cellular regulation in terms of genes and proteins will be helpful to understand the metabolic burden, thereby recombinant protein production associated with cellular reprogramming.

Dietary supplementation with Bacillus subtilis KC1 alleviates the negative effects of Mycoplasma gallisepticum on growth performance and amino acid metabolism of broiler chickens

Project description:The aim of this study was to explore whether, and if so, how Bacillus subtilis KC1 can enhance the growth performance of broilers that have been adversely affected by Mycoplasma gallisepticum (MG) infection. A total of 96 1-day-old male broilers were randomly divided into 4 groups: the control group (basal diet), the MG group (basal diet + MG challenge), the Bacillus subtilis KC1 group (basal diet + Bacillus subtilis KC1 supplementation), the Bacillus subtilis KC1 + MG group (basal diet + Bacillus subtilis KC1 supplementation + MG challenge). The trial lasted 42 days, and the results showed that the MG group had significantly reduced body weight and average daily gain, as well as increased feed conversion ratio of broilers, compared to the control group. Dietary supplementation with Bacillus subtilis KC1 significantly improved the growth performance of MG-infected broilers. In addition, dietary supplementation with Bacillus subtilis KC1 significantly improved oxidative stress and inflammatory response markers, characterized by increased superoxide dismutase levels and reduced levels of malondialdehyde, interleukin-1β, and tumor necrosis factor-α. Furthermore, both metabolomics and transcriptomics analyses indicated that MG infection markedly disrupted amino acid metabolism in broilers, whereas Bacillus subtilis KC1 supplementation alleviated the abnormal amino acid metabolism caused by MG infection. These results suggested that Bacillus subtilis KC1 may alleviate the poor growth performance caused by MG infection in broilers by improving amino acid metabolism.

Improved Fermentative Production of Gamma-Aminobutyric Acid via the Putrescine Route: Systems Metabolic Engineering for Production From Glucose, Amino Sugars, and Xylose

Project description:Gamma-aminobutyric acid (GABA) is a non-protein amino acid widespread in Nature. Among the various uses of GABA, its lactam form 2-pyrrolidone can be chemically converted to the biodegradable plastic polyamide-4. In metabolism, GABA can be synthesized either by decarboxylation of L-glutamate or by a pathway that starts with the transamination of putrescine. Fermentative production of GABA from glucose by recombinant Corynebacterium glutamicum has been described via both routes. Putrescine-based GABA production was characterized by accumulation of by-products such as N-acetyl-putrescine. Their formation was abolished by deletion of the spermi(di)ne N-acetyl-transferase gene snaA. To improve provision of L-glutamate as precursor 2-oxoglutarate dehydrogenase activity was reduced by changing the translational start codon of the chromosomal gene for 2-oxoglutarate dehydrogenase subunit E1o to the less preferred TTG and by maintaining the inhibitory protein OdhI in its inhibitory formby changing amino acid residue 15 from threonine to alanine. Putrescine-based GABA production by the strains described here led to GABA titers up to 63.2 g L-1 in fed-batch cultivation at maximum volumetric productivities up to 1.34 g L-11 h1-1, the highest volumetric productivity for fermentative GABA production reported to date. Moreover, GABA production from the carbon sources xylose, glucosamine, and N-acetyl-glucosamine that do not have competing uses in the food or feed industries was established.
