Summary:
-
Bacteria Discovery
Scientists have found that Comamonas testosteroni, a bacterium commonly found in wastewater, can break down polyethylene terephthalate (PET), a plastic prevalent in single-use packaging and bottles. -
Plastic Waste Statistics
PET accounts for about 12% of global solid waste, with 90 million tons produced annually, making this discovery crucial in addressing pollution issues. -
Unique Feeding Mechanism
Unlike many bacteria that thrive on sugar, C. testosteroni can consume chemically complex materials, including plastics, which typically take longer to decompose. -
Breakdown Process
The research outlines a six-step process in which the bacteria first physically chew the plastic into smaller pieces and then use enzymes to chemically convert it into terephthalate, a carbon-rich food source. -
Decomposition Timeline
Although the bacteria can break down plastic, it takes several months to process larger chunks. To enhance efficiency, scientists are exploring ways to accelerate their growth by providing additional nutrients, such as acetate. -
Potential for Environmental Solutions
Researchers believe that harnessing the natural abilities of environmental microbes like C. testosteroni could lead to sustainable solutions for combating plastic pollution.
