Nutritional Evaluation Of Mealworms From Poly(3-Hydroxybutyrate) Recovery And Its Potential Application As Aquaculture Feed Ingredient
Polyhydroxyalkanoates (PHAs) are interesting bio-based polymers to replace some petrochemical plastics. To date, the selling price of PHA is high due in part to the costly downstream processes in PHA production. Furthermore, the non-PHA part of the bacterial cells which is nutritive, is lost during...
