Enhancing the Plastic-Degrading Capabilities of Chlorella Vulgaris via Genetic Engineering
Summary
Scientists are trying to genetically engineer a common algae to break down plastic waste faster, which could eventually help reduce the microplastics polluting our oceans, lakes, and drinking water. This early-stage research is still working out the basic lab techniques—the team's first modified algae sample didn't survive, so they're starting over with a new one. While there's no working solution yet, this kind of research matters because microplastics are increasingly found in our food and bodies, and finding ways to break them down could reduce our exposure down the road.
In today’s world, pollution is a critical environmental challenge, particularly regarding plastic and microplastic pollution. While Chlorella Vulagris already has a limited ability to degrade plastics, we aim to enhance its efficiency through genetic engineering. The first step in this research was to introduce our DNA into the algae samples. Following our addition of plastic-degrading enzymes to the algae samples, we selected one clone from about 20 others and isolated it after introducing the DNA. After isolating our clones, we screened them for the DNA and proteins introduced at the beginning of this research. We will then be using this clone to test the % degradation of plastic. There were several initial problems with the clone I had selected, but it ultimately contained DNA and proteins. Even though the clone I had selected, isolated, and tested contained the DNA, it did not continue to grow, so I will not be able to use it. So, I have selected a new clone, and I will be starting the process again. By following the same steps, I will obtain a new clone with the DNA present and a continuously growing clone that I will be able to use in the plastic degradation section of this research. By accelerating the breakdown of synthetic polymers, this research continues to help us develop solutions to mitigate plastic waste in our oceans and freshwater systems. Providing us with information to build upon for further research in the future.
