Like the stripes of the rainbow, the different biotechnology applications are grouped into seven colours or research and development areas. In this section, we highlight the most relevant of each of them.
- Red biotechnology: This is the health branch and responsible, according to the Biotechnology Innovation Organization (BIO), for the development of more than 250 vaccines and medications such as antibiotics, regenerative therapies and the production of artificial organs.
- Green biotechnology: It is used by more than 13 million farmers worldwide to fight pests and nourish crops and strengthen them against microorganisms and extreme weather events, such as droughts and frosts.
- White biotechnology: The industrial branch works to improve manufacturing processes, the development of biofuels and other technologies to make industry more efficient and sustainable.
- Yellow biotechnology: This branch is focused on food production and, for example, it carries out research to reduce the levels of saturated fats in cooking oils.
- Blue biotechnology: This exploits marine resources to obtain aquaculture, cosmetics and health care products. In addition, it is the branch most widely used to obtain biofuels from certain microalgae.
- Grey biotechnology: Its purpose is the conservation and restoration of contaminated natural ecosystems through, as mentioned above, bioremediation processes.
- Gold biotechnology: Also known as bioinformatics, it is responsible for obtaining, storing, analysing and separating biological information, especially that related to DNA and amino acid sequences.
