Breakthrough in Biotechnology: Genome Mining of Polystyrene Degrading Enzymes

Research conducted at China Nuclear Power Engineering Co. Ltd. has led to a significant discovery in the field of biotechnology. Investigators isolated a microorganism, Cytobacillus sp. BC1816, from a Pacific Ocean marine sediment sample that can thrive on polystyrene plastic as its only carbon source. This breakthrough has the potential to revolutionize the field of biotechnology, enabling the development of enzymes that can degrade polystyrene, a widely used plastic.

Key Takeaways:

• Cytobacillus sp. BC1816, a microorganism isolated from a Pacific Ocean marine sediment sample, can thrive on polystyrene plastic as its only carbon source.
• The genome of Cytobacillus sp. BC1816 contains several putative polystyrene-degrading enzymes, including peroxidases and cytochrome P450s.
• The genome has a mean G + C content of 41.43% and a total length of 5,343,034 base nucleotides.
