On the other hand, the aquaculture feed industry needs a low-cost mealworm meal as a protein source. The biological approach of using mealworms, Tenebrio molitor, for the recovery of PHA from the bacterial cells is a newly established method that is at the scale-up stage.

It has always been a challenge to commercialise PHA due in part to the costly recovery processes of the PHA granules from the bacterial cells. Polyhydroxyalkanoates (PHAs) are bio-based polymers produced in bacterial cells to replace some petrochemical plastics.
