Engineered Algae for Plastic Degradation
AI summary Read the abstract
Scientists genetically modified a type of algae to produce two enzymes that can break down common plastic waste, successfully creating and verifying a strain that carries this plastic-eating ability. While this is still an early-stage proof of concept, it points toward a future where engineered algae could help clean up plastic pollution in oceans and waterways — which matters because plastic breaks down into microplastics that are increasingly found in our food, water, and even our bodies.
Plastic pollution is a widespread problem worldwide that has become a major threat to our ecosystems. This semester, our goal was to produce a strain of algae that produces MHETase and PETase, enzymes that break down Type-1 plastics. DNA that coded for these proteins was introduced to our alga, Chlorella vulgaris. Clones were selected and screened for the added DNA and protein production to be isolated and tested for plastic degradation. A successful clone was chosen from the candidates and a DNA sample was taken and isolated for proof of the gene that produced our enzymes. These algae clones can be used to break down plastic in our ecosystem and bring plastic pollution to an end.

Algae vs Plastic
AI summary Read the abstract
Scientists genetically modified a common type of algae to produce enzymes that can break down plastic bottles, successfully confirming the algae took up the plastic-degrading genes. They're now testing how well this algae actually eats away at real plastic. If it works, this algae could one day be used to clean up plastic pollution directly in rivers and oceans, potentially reducing the microplastics that end up in our water, food, and bodies.
Plastic-degradation Properties of Genetically Modified Algae
AI summary Read the abstract
Scientists are genetically engineering a type of algae to produce enzymes that break down plastic, aiming to tackle the growing problem of microplastic pollution in our food and water. In this early-stage study, researchers successfully modified the algae's DNA and grew one promising sample in the lab, though more testing is needed before this could be used to actually clean up microplastics at a larger scale. This matters because microplastics are notoriously hard to filter out of water due to their tiny size, and finding a biological way to break them down could eventually help reduce human exposure to this widespread contaminant.
Plastic-Eating Algae
AI summary Read the abstract
Scientists successfully engineered algae to carry genes from plastic-eating bacteria, creating tiny organisms with the potential to break down plastic waste. While this early-stage lab work still needs testing to confirm it actually degrades plastic effectively at scale, it points toward a promising future tool for tackling plastic pollution—which matters for human health since plastic waste breaks down into microplastics that end up in our water, food, and even our bodies.
Plastic Eating Algae Project
AI summary Read the abstract
Scientists engineered algae to carry genes for plastic-eating enzymes, successfully creating algae clones that break down plastic. This matters because plastic pollution doesn't just harm wildlife—it breaks down into microplastics that end up in our water, food, and eventually our bodies, so finding ways to clean up plastic waste could reduce our long-term exposure. While this research is still early-stage, it points toward a promising, low-cost tool for tackling plastic pollution at its source.
Plastic Pollution Degradation Experiment
AI summary Read the abstract
Scientists are trying to engineer algae that can "eat" plastic waste, which could one day help shrink the mountains of plastic polluting our oceans and land—plastic that eventually breaks down into microplastics found in our food, water, and even our bodies. So far, the team successfully modified algae cells but hasn't yet confirmed the plastic-degrading gene took hold, so this is an early, unproven step rather than a working solution. It's a hopeful idea worth watching, but there's no evidence yet that it actually reduces plastic pollution.
