An integrative study on biologically recovered polyhydroxyalkanoates (PHAs) and simultaneous assessment of gut microbiome in yellow mealworm.

Polyhydroxyalkanoates (PHAs) are produced in microbes as a source of carbon and energy storage. They are biodegradable and have properties similar to synthetic plastics, which make them an interesting alternative to petroleum-based plastics. In this study, a refined method of recovering PHA from Cupriavidus necator biomass was proposed by incorporating the use of the yellow mealworm (the larval phase of the mealworm beetle, Tenebrio molitor) as partial purification machinery, followed by washing of the fecal pellets with distilled water and sodium hydroxide.
