Biodegradation of low concentration of monochloroacetic acid-degrading Bacillus sp. TW1 isolated from terengganu water treatment and distribution plant
Haloacetic acids (HAAs) are group of chemicals formed due to disinfect ion by products that can be detected during chlorination and chloramination of processed drinking water. In this study, Bacillus sp. strain TW1 identified by morphological/biochemical and PCR-amplified 16S rRNA gene was isolated...
