. The MS components were introduced into POME culture medium to improve the propagation of H. callitrichoides. 1/2 strength POME medium with liquid full strength MS medium as supplements (Media E) was proven to be better than full strength MS medium (Media A) and other culture media due to its ability in suppressing the morphological changes that occurred in full strength MS medium and promote the maximum growth of H. callitrichoides. The reliance on treated POME as additional supplement towards the healthy growth of H. callitrichoides. Most importantly the availability of free treated POME do not contribute towards the additional cost of cultivation and prevent the reliance on high cost of commercial supplement.
