Cyanobacteria as new Superproducers of Cyanophycin

The amino acid polymer cyanophycin can serve as a new and sustainable feedstock for so far petroleum-based plastics or polyaspartic acid. Here we present for the first time cyanobacteria that are able to produce large quantities of cyanophycin. This is mainly achieved by use of a novel variant of the PII protein.
