Original Abstract

Extremophilic organisms are promising producers of biotechnological productions, because thanks to living in extreme conditions the biotechnological process is not so demanding on sterility and the biotechnological price of production is cheaper. Polyhydroxyalkanoates are microbial polyesters that are fully degradable and biocompatible. They are also a good alternative to petroleum polymers. Using our original protocol to isolate thermophilic PHA producers from natural source, we isolated the bacteria, which, was designated as Aneurinibacillus sp. H1. This bacterium is capable of producing poly(3-hydroxybutyrate) (P3HB) on glycerol (even on waste glycerol) , and, furthermore, when supplemented with proper precursors, it is able to produce copolymer poly(3-hydroxybutyrate-co-3-hydroxyvalerate) or poly(3-hydroxybutyrate-co-4-hydroxybutyrate) or even terpolymer poly(3-hydroxybutyrate-co-4-hydroxybutyrate-co-3-hydroxyvalerate) with very high 4-hydroxybutyrate and 3-hydroxyvalerate fractions.
