The objective of the entire project is the cheaper production for faster implementation of cleaner biopolymer-based materials. PHAtex stands for the development of a green process chain, to produce biopolymer textiles from various renewables feedstocks at a competitive price. As a part of the PHAtex project​​​​​​​ we focus on genetical engineering of the Ralstonia eutropha strain used for PHA production. We aim at the identification of putative regulators of genes involved in PHA production and degradation as well as genetical engineering of the strain in order to broaden the substrate spectrum of the strain.
