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...

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 the PHA recovery process. High cell density cultures of Cupriavidus necator H16 (161 g/L cell dry weight) and an improved biological recovery method of PHA by using mealworms (Tenebrio molitor), were established. Freeze-dried washed and unwashed cells containing 70 ± 2.0 wt% P(3HB) were fed to mealworms at 12.5% of their body weight (125 g of cell/ 1kg of mealworms). Washed cells was more palatable and consumed daily due to its lower content of mineral salts compared to the alternate days consumption of unwashed cells. 2019-12 Thesis http://eprints.usm.my/55731/ http://eprints.usm.my/55731/1/24%20Pages%20from%20Zainab%20Ladidi%20Idris.pdf application/pdf en public phd doctoral Universiti Sains Malaysia Pusat Pengajian Sains Kajihayat
