Exploring the secretome of Corynebacterium glutamicum ATCC 13032

Project description:The demand for alternative sources of food proteins is increasing due to the limitations and challenges associated with conventional food production. Advances in biotechnology have enabled the production of proteins using microorganisms, thus prompting the exploration of attractive microbial hosts capable of producing functional proteins in high titers. Corynebacterium glutamicum is widely used in industry for the production of amino acids and has many advantages as a host organism for recombinant protein production. However, its performance in this area is limited by low yields of target proteins and high levels of native protein secretion. Despite representing a challenge for heterologous protein production, the C. glutamicum secretome has not been fully characterized. In this study, state-of-the-art mass spectrometry-based proteomics was used to identify and analyze the proteins secreted by C. glutamicum. Both the wild-type strain and a strain that produced and secreted a recombinant ß-lactoglobulin protein were analyzed. A total of 427 proteins were identified in the culture supernatants, with 148 predicted to possess a secretion signal peptide. The top 12 most abundant proteins accounted for almost 80% of the secretome. These are uncharacterized proteins of unknown function, resuscitation promoting factors, protein PS1, Porin B, ABC-type transporter protein and hypothetical membrane protein. The data from this study can provide valuable insight for researchers looking to improve protein secretion and optimize C. glutamicum as a host for secretory protein production.

Transcriptome analysis of C. glutamicum ΔaceE Δpyc versus ΔaceE

Project description:The pyruvate dehydrogenase complex (PDHC) catalyzes the oxidative decarboxylation of pyruvate yielding acetyl-CoA and CO2. The PDHC-deficient Corynebacterium glutamicum strain ΔaceE is therefore lacking an important decarboxylation step in central metabolism. Additional inactivation of pyc, encoding pyruvate carboxylase, resulted in a >15 hour lag phase in the presence of glucose, while no growth defect was observed on gluconeogenetic substrates like acetate. Transcriptome analysis as well as an adaptive laboratory evolution experiment of strain ΔaceE Δpyc revealed the reduction of glucose uptake as a key adaptive measure to enhance growth on glucose/acetate mixtures.

Global transcriptomic analysis of the response of Corynebacterium glutamicum to vanillin

Project description:Lignocellulosic biomass is an abundant and renewable resource for biofuels and bio-based chemicals. Vanillin is one of the major phenolic inhibitors in biomass production using lignocellulose. To assess the response of Corynebacterium glutamicum to vanillin stress, a global transcriptional response analysis was performed by using microarray.
