Construction of Recombinant Pdu Metabolosome Shells for Small Molecule Production in Corynebacterium glutamicum.

Bacterial microcompartments have significant potential in the area of industrial biotechnology for the production of small molecules, especially involving metabolic pathways with toxic or volatile intermediates. Corynebacterium glutamicum is an established industrial workhorse for the production of amino acids and has been investigated for the production of diamines, dicarboxylic acids, polymers and biobased fuels. Herein, we describe components for the establishment of bacterial microcompartments as production chambers in C.

Heterologous expression of the Halothiobacillus neapolitanus carboxysomal gene cluster in Corynebacterium glutamicum.

Compartmentalization represents a ubiquitous principle used by living organisms to optimize metabolic flux and to avoid detrimental interactions within the cytoplasm. Proteinaceous bacterial microcompartments (BMCs) have therefore created strong interest for the encapsulation of heterologous pathways in microbial model organisms. However, attempts were so far mostly restricted to Escherichia coli.

Investigating the dynamics of recombinant protein secretion from a microalgal host.

Production of recombinant proteins with microalgae represents an alternative platform over plant- or bacterial-based expression systems for certain target proteins. Secretion of recombinant proteins allows accumulation of the target product physically separate from the valuable algal biomass. To date, there has been little investigation into the dynamics of recombinant protein secretion from microalgal hosts-the culture parameters that encourage secreted product accumulation and stability, while encouraging biomass production.
