Plastics often contain additives such as flame retardants, plasticisers, and stabilisers, with phosphorus-based compounds playing a key role in microbial interactions. Most previous studies have focused on heterotrophic microbes targeting carbon backbones, but their degradation efficiency remains limited. This study examined the phosphorus-solubilising ability of autotrophic cyanobacteria carrying the phoD gene to weaken polyp...
