Beyond infections, bacteria reveal promise for making medicines and protecting crops
Bacteria get a bad reputation—with all the outbreaks, infections and deaths.
Beyond the common perception of bacteria as disease-causing agents, scientists are uncovering their potential to revolutionize medicine, agriculture, and space exploration. The Bioplastics Innovation Hub discovered a type of salt-loving bacteria called Salinivibrio that can produce biodegradable bioplastic called polyhydroxyalkanoate (PHA).
PHA offers a more sustainable alternative to traditional plastic, with applications ranging from food packaging to medical implants. Meanwhile, genetically engineered E. coli bacteria are being used to convert plastic waste into the medication Levodopa, a treatment for Parkinson's disease. Researchers are also exploring bacteria's potential to aid human colonization of Mars.
By harnessing the abilities of Sporosarcina pasteurii and Chroococcidiopsis bacteria, scientists can create concrete-like materials from Martian soil, addressing the challenge of building infrastructure in an extreme environment. Additionally, bacteria such as Streptomyces and Leifsonia are being employed to improve wheat plant resilience to drought conditions, potentially leading to higher crop yields and enhanced food security in a world grappling with climate change and water scarcity.
