String Bio: How biotechnology can turn waste carbon into wealth

String Bio: How biotechnology can turn waste carbon into wealth – Carbon is one of the most abundant and versatile elements in nature, and the building block of life. However, carbon is also a major contributor to climate change, as the excess emission of greenhouse gases, such as carbon dioxide and methane, traps heat in the atmosphere and causes global warming. According to the World Bank, the global carbon footprint was 36.44 billion metric tons in 2016, and is expected to rise further in the coming year. This poses a serious threat to the environment, as well as the economy and society.

What is String Bio’s solution?

String Bio’s solution is based on the concept of gas fermentation, which is a process that uses microorganisms to convert gaseous substrates, such as carbon dioxide and methane, into biomass and products. String Bio has developed a proprietary platform, called STRING, which stands for Synthetic Technology for Recycling of Industrial Natural Gas. The platform consists of three components:

  • A genetically engineered strain of bacteria, which can utilize methane as the sole carbon and energy source, and produce a variety of products, such as proteins, organic acids, and alcohols.
  • A bioreactor, which is a device that provides optimal conditions for the growth and metabolism of the bacteria, and allows the continuous conversion of methane into products.
  • A downstream processing unit, which is a system that separates and purifies the products from the biomass and the residual gases.

Using the STRING platform, String Bio can produce high-quality and cost-effective products from waste carbon, such as:

  • Single-cell protein (SCP), which is a protein-rich biomass that can be used as an alternative source of protein for animal feed and human food. SCP has several advantages over conventional protein sources, such as soybean and fishmeal, such as higher protein content, lower environmental impact, and lower risk of contamination and disease.
  • Bio-based chemicals, such as succinic acid and isopropanol, which can be used as building blocks for the production of high-performance polymers, such as bioplastics and biofuels. Bio-based chemicals have several advantages over fossil-based chemicals, such as lower greenhouse gas emissions, higher biodegradability, and higher compatibility with biological systems.
