The global market for the industrial manufacturing of recombinant proteins (RPS) is steadily increasing and demand will keep rising in years to come. Currently, RPs are already an integral part of disease therapeutics, agriculture and the chemical industry and RP manufacturing methods rely heavily on host systems such as prokaryotes and, to a lesser extent, mammalian, yeast and plant cells. When comparing these host systems, all have their specific strengths and weaknesses and numerous challenges remain to improve protein manufacturing on an industrial scale.
In this project, GLO Biotics proposes an innovative plant-based RP expression platform with the potential of significantly reducing costs and process requirements compared to the current state-of-the-art systems. Specifically, this novel concept is based on the use of coconut water as a natural, cell-free ‘protein production factory’. Coconut water in nuts aged 4-6 months is composed of free-floating cell nuclei devoid of cell walls, and it has been demonstrated these nuclei can express foreign proteins. Compared to existing platforms, the relative ease of delivering foreign protein-coding genes into this system, as well as the ease of recovery of the produced protein, potentially offers an innovative platform with great commercial attractiveness.
In summary, the aim of this project is to provide a proof-of-concept for coconut water as a novel and competitive RP production platform by demonstrating the production and recovery of several commercially available RPs. To this end, GLO Biotics intends to collaborate with Zuyd University of Applied Sciences (Zuyd) and the Aachen Maastricht Institute for Biobased Materials (AMIBM) in demonstrating the potential of the ‘GLO-Conuts’ expression system. As a consortium, Zuyd and GLO Biotics will utilize their shared experience in molecular engineering and DNA vector technology and AMIBM will bring their expertise in plant-based RP production and recovery.
