EXTRAÇÃO DE POLI(3-HIDROXIBUTIRATO), PRODUZIDO POR Cupriavidus necator, COM CARBONATO DE PROPILENO

The environmental impact of plastic waste has attracted worldwide attention. Amid the current context of increasing concern for the environment, biodegradable plastics have been widely studied as a replacement for synthetic plastics. Poly(3-hydroxybutyrate) (P(3HB)) is a biopolymer stored as an intracellular energy and reserve source in many microorganisms. Because it is an intracellular product, P(3HB) must be extracted from the cells at the end of the culture. The purpose of this study was to investigate the effect of extraction time, heating temperature, first standing time (after filtratio...
