Genus Aneurinibacillus - “hot” and interesting producer of polyhydroxyalkanoates

Abstract

Polyhydroxyalkanoates (PHA) are very interesting and promising materials microbial polyester which are produced by many various bacteria. Additionally, there are completely biodegradable and biocompatible, providing a wide range of end uses. PHA can also be produced from renewable sources, making them a suitable alternative to plastics made from petroleum. Using our original protocol, we isolated thermophilic PHA producers from natural samples (compost, activated sludge). Most of the obtained strains belonged to the genus Aneurinibacillus, so we paid attention to this genus in terms of biotechnological potential. Aneurinibacilli proved to be interesting PHA producers with great potential. These bacteria are capable of producing not only homopolymers composed only of 3-hydroxybutyrate (3HB) units but also copolymers that contain 4-hydroxybutyrate in addition to the 3HB monomer or other very unusual monomers such as 3-hydroxyvalerate, 4-hydroxyvalerate or 5-hydroxyvalerate.
