Cross-feeding and co-degradation within a bacterial consortium dominated by challenging-to-culture <i>Leucobacter</i> sp. HA-1 enhances sulfonamide degradation.

ABSTRACT: The use of sulfonamides (SAs) leads to residual environmental pollution. Bacteria play a crucial role in the degradation of SAs, and microbial consortium offers advantages over single bacterium. However, the complexity of the degradation processes and interaction mechanisms within such consortia remains a mystery. Here, a consortium named ACJ, comprising Leucobacter sp. HA-1, Bacillus sp. HC-1, and Gordonia sp. HAEJ-1, isolated from activated sludge in the wastewater treatment facilities of pharmaceutical plants, was identified as capable of degrading various SAs. Here, a pure culture of Leucobacter sp. HA-1, which plays a key role in SAs degradation, was obtained with the auxotrophic requirements (ARs) provided by strains HC-1 and HAEJ-1. Strain HA-1 initiated
