Milking of Microalgal Cells with Pulse Electric Field Technology

Our project explores a sustainable way to extract valuable compounds from microalgae, such as proteins, sugars, oils and pigments, without harming the cells. Using gentle electric pulses, we stimulate the algae to release these compounds while keeping them alive and productive. This innovative approach, inspired by "milking," aims to make biofuel, nutraceutical, and pharmaceutical production more efficient, eco-friendly, and cost-effective. The goal is to revolutionize how we harness microalgae for a greener future.

Project description

Microalgae are a powerhouse of bioactive compounds, including lipids, pigments, and proteins, with applications in biofuels, nutraceuticals, and pharmaceuticals. However, traditional methods of extracting these valuable compounds often involve harvesting and disrupting the cells, which can be energy-intensive, costly, and unsustainable.

Our groundbreaking project explores the use of Pulse Electric Field (PEF) Technology to "milk" microalgal cells—a non-destructive, continuous extraction process that allows cells to remain alive and productive while releasing their valuable metabolites. This innovative approach mimics the concept of milking, where microalgae are repeatedly stimulated to secrete target compounds without being destroyed, enabling sustainable and efficient bioproduction.

How it works

Pulse Electric Field Technology applies short, high-voltage electric pulses to microalgal cultures, creating temporary pores in the cell membranes. This process, known a selectroporation, facilitates the release of intracellular compounds while maintaining cell viability. By optimizing parameters such as pulse duration, voltage, and frequency, we can selectively extract specific metabolites, such as lipids for biofuels or carotenoids for nutraceuticals, without harming the cells.

Key advantages

  • Sustainability: Reduces the need for cell destruction and regrowth, minimizing energy and resource consumption.
  • Efficiency: Enables continuous extraction, increasing productivity and reducing downtime.
  • Selectivity: Allows targeted extraction of specific compounds, enhancing product purity and value.
  • Scalability: PEF technology is adaptable for large-scale industrial applications, making it a viable solution for commercial bioproduction.

Applications

This technology has far-reaching implications across multiple industries:

  • Biofuels: Efficient extraction of lipids for biodiesel production.
  • Nutraceuticals: Sustainable production of high-value pigments like astaxanthin and beta-carotene.
  • Pharmaceuticals: Gentle extraction of bioactive compounds for drug development.
  • Cosmetics: Production of natural pigments and antioxidants for skincare products.

Our vision

By harnessing the potential of Pulse Electric Field Technology, we aim to revolutionize microalgal bioprocessing, making it more sustainable, cost-effective, and environmentally friendly. This project represents a significant step toward a circular bioeconomy, where renewable resources are utilized efficiently to meet global demands for energy, food, and health.
