Lactic Acid Bacteria, or LAB, are widely used in the food industry, particularly in fermented products like yogurt, cheese, fermented meats and vegetables. This study examines the possibility of using agricultural waste (corn cob waste, banana peels, and mature coconut water), as plant-based alternatives in the proliferation of LAB. Wastes medium were used to grow two LAB strains, Lacticaseibacillus paracasei BUM6 and Lactobacillus casei Shirota, and the growth were compared to that observed in commercial MRS broth and agar. The findings indicated that enrichment of corn cob media with mature coconut water promoted the growth of LAB as compared to the control MRS media. Banana peel media on the other hand had some or no bacterial growth (p < 0.05) probably due to some antimicrobial elements and absence of available nutrients. The corn cob had potential in offering a feasible and cost-effective alternative. The research focuses on the utilization of agricultural waste into culture media of microbial strains that can be used in resourceful biotechnology incorporating halal requirements and the original concepts of a circular economy.
