Original Abstract

Polyhydroxyalkanoates (PHA) are microbial polymers that serve as a source of carbon and energy for bacteria. Moreover, they are a suitable alternative to polymers produced from fossil resources. Although they have many advantages - biocompatibility, biodegradability, wide application use; their production costs are still high. Over 40 thermophilic strains were obtained using an original isolation protocol that uses changes in osmotic stress as a selection. After characterization, a large proportion of these strains were assigned to the previously poorly described Aneurinibacillus species. However, the genus Aneurinibacillus appears to be a very interesting PHA producer with great potential. Firstly, it can use waste glycerol as a carbon source, but also synthesizes interesting and unusual copolymers when suitable precursors are used. Isolates of this genus are able to incorporate PHA monomers such as 4-hydroxybutyrate in high fraction content (up to 90 mol.%) into their polymers. Also, with the use of a suitable precursor, 4-hydroxyvalerate, 5-hydroxyvalerate, but also monomers of mcl- PHA namely 3-hydroxyhexanoate or 4-hydroxyhexanoate can be incorporated into the PHA structure
