2. First discovered in river bottom mud. Many species such as Geobacter and Shewanella are found in oxygen-poor environments rich in organic matter. Photo: medium.com.

3. Producing electricity from organic waste. They can decompose garbage, sludge or organic compounds and convert chemical energy into electricity. Photo: tsukuba.ac.jp.

4. Applications in biological batteries. Scientists have exploited them to make microbial batteries, providing energy for small devices. Photo: mit.edu.

5. It is possible to transmit electricity through biological nanowires. Some species produce ultra-thin conductive threads that connect cells to electrode surfaces. Photo: researchgate.net.

6. Contribute to environmental pollution treatment. They can remove heavy metals or toxins in wastewater while generating electricity. Photo: springernature.com.

7. Can function in oxygen-free environments. Their ability to breathe anaerobically allows them to survive in harsh conditions underground or at the bottom of the sea. Photo: lshtm.ac.uk.

8. Promising applications beyond Earth. NASA is studying this bacteria to produce energy for long-term space missions. Photo: Nicholas School Blogs.
