PHA biosynthesis, recovery, and application: A circular value chain for production of self-healing concrete from waste

Polyhydroxyalkanoates (PHA) are a family of biopolymers produced intracellular<br/>by a range of different bacteria.PHA have attracted widespread attention as<br/>an environmental friendly replacement of fossil-based polymers, because they<br/>have thermoplastic and/or elastomeric properties, and are also biobased and<br/>biodegradable.Moreover,...

Production of a newly discovered PHA family member with an isobutyrate-fed enrichment culture

Abstract: Using microbial enrichment cultures for the production of waste-derived polyhydroxyalkanoates (PHAs) is a promising technology to recover secondary resources. Volatile fatty acids (VFAs) form the preferred substrate for PHA production. Isobutyrate is a VFA appearing in multiple waste valorization routes, such as anaerobic...
