Method & Evidence

AimCan lipid-rich surplus streams from the animal processing industry be biotechnologically converted into structurally diverse poly(hydroxyalkanoates) (PHAs) with commercially relevant properties?
MethodBiotechnological conversion and material characterization
ProcedureLipid-rich by-products from slaughterhouses and rendering were chemically transformed into crude glycerol phase (CGP) and saturated fatty acid ethyl esters (SFAE). These streams were then used as carbon sources for microbial fermentation by specific bacterial strains (Cupriavidus necator, Pseudomonas citronellolis, Pseudomonas chlororaphis) to produce various types of PHAs. The resulting biopolymers were isolated and characterized for their structural diversity and material properties.
