Biodegradation of Picolinic Acid by Rhodococcus sp. PA18 [PDF]

Applied Sciences, 2019
Picolinic acid (PA), a C2-carboxylated pyridine derivative, is a significant intermediate used in industrial production. PA is considered hazardous for the environment and human health. In this study, a Gram-positive bacterium, Rhodococcus sp. PA18, which aerobically utilizes PA as a source of carbon and energy, was isolated.
