At Leiden University, researchers are shedding light on the potential of bacteria to break down plastics. In a study published in Nature Communications Biology, researcher Jo-Anne Verschoor found that more than 18 percent of bacterial strains were able to degrade plastics effectively. However, it was discovered that bacteria require specific conditions, such as being starved of other nutrients, to break down plastics efficiently.
Verschoor’s findings could have significant implications for addressing plastic waste problems. By identifying bacteria that can break down plastic into smaller particles, recycling processes could become more efficient. This discovery was made by chance while researchers at Leiden University were investigating new antibiotics.
In laboratory experiments, Verschoor exposed different species of bacteria to various substances and conditions to observe their ability to break down plastic. In the past, research on the decomposition of plastics by bacteria has focused on which types of bacteria thrive in landfills. However, Verschoor’s research could potentially broaden the range of bacteria that can be utilized to break down plastic.
This discovery holds promise for addressing the global plastic waste crisis and finding innovative solutions for recycling plastics more effectively. By starving bacteria and providing them with different plastic models, Verschoor’s research could potentially lead to more efficient and sustainable recycling methods for plastics.
