Antagonism of Microbial Consortium Decomposers in Deadly Water-borne Pathogens in Domestic Wastewater

Abstract

The higher the domestic waste pollutes the body of water, the more likely it is to cause various infectious diseases to spread easily. Domestic waste must be controlled and processed first with ecofriendly methods and techniques to avoid a negative impact on public health and environment. The potential microbe which decomposes the waste and kills the pathogens is produced in the laboratory. An antagonistic test of pathogens to explore the potential of microbial strains found biological pesticides in lethal pathogenic microbes which exist in domestic wastewater. The bacteria test consists of pathogens, namely Salmonella typhi, Shigella dysenteriae, Vibrio cholerae, and Escherichia coli. The consortium consists of 4 strains of bacteria namely Bacillus cereus strain BQAR-01d 16 S rRNA (A), Bacillus thuringiensis strain MSS-2 16 S rRNA (B), Bacillus cereus strain JDA-1 16 S rRNA (C), and Bacillus sp. B31 (2008) 16 S rRNA (D). The consortium formula consists of ABC, ABD, BCD, and ABCD consortium strain. The result shows that the consortium formula of heterotrophic bacteria strain with the highest antagonistic power against pathogens in vitro is the ABC consortium formula. This formula can be used as a consortium of waste decomposers to reduce negative impacts on public health and the environment.
