Abstract

An experiment was done to determine the efficacy of waste bottom ash as an effective microbial carrier. Bottom ash found to be a suitable microbial carrier. The average of viable cells of Paenibacillus polymyxa GS01 (as a test biocontrol agent) in bottom ash samples was about 10⁸ cfu/10±2 mg. The surface of bottom ash coated with 5% PVA w/v was most effective for improvement of cell viability. TSB medium containing 50 mg/L of MnSO₄·H₂O was the best for spore production of P. polymyxa GS01. Thus waste bottom ash coating with 5% PVA is likely to be suitable for use as a microbial carrier.
