A three-member synthetic microbial community comprising Sphingopyxis sp. GC21, Ochrobactrum sp. TCC-2, and Apiotrichum sp. IB-1. Xu et al. assembled the two bacterial strains and one fungal strain to enhance simultaneous removal of the pharmaceutical and personal care products chloramphenicol, triclocarban, and naproxen from simulated wastewater and real domestic wastewater under aerobic and anoxic conditions.

Simultaneous chloramphenicol-triclocarban-naproxen removal
The introduced Sphingopyxis sp. GC21, Ochrobactrum sp. TCC-2 and Apiotrichum sp. IB-1 SMC enhanced simultaneous chloramphenicol, triclocarban and naproxen removal in simulated and real wastewater. The accessible abstract reports aerobic simulated-wastewater removal of 97.83%, 68.19% and 85.34%, respectively, within 8 h; aerobic real-wastewater values exceeded 70%, and anoxic values exceeded 60% in both matrices. These are aggregate removal outcomes, not complete mineralization, resolved per-strain transformation assignments or demonstrated inter-member metabolite exchange. Indigenous wastewater organisms may contribute.

Knowledge gaps & discussions (2)
KNOWLEDGE_GAP OPEN Which PPCP transformation reactions were carried out by Sphingopyxis sp. GC21, Ochrobactrum sp. TCC-2, Apiotrichum sp. IB-1, and indigenous wastewater members, and what inoculation ratio and medium recipe were used for the simulated- and real-wastewater reactors?
The accessible PubMed abstract reports the three introduced strains, the three target PPCPs, aerobic and anoxic removal endpoints, and aggregate CAP/TCC/NPX transformation chemistry, but it does not allocate each reaction to a specific strain or report inoculation ratios, wastewater composition, or reactor operating details.
Attaches to: engineering_design, ecological_interactions#Simultaneous chloramphenicol-triclocarban-naproxen removal
KNOWLEDGE_GAP OPEN Which introduced and indigenous organisms mediate each transformation, and is metabolite transfer responsible for improved removal?
The abstract reports transformation classes, detoxification and ARG responses, but controls and full-text assays have not been inspected. Genus relative abundances do not establish strain-resolved persistence, and bacterial/fungal fractions need not share a denominator. Preserve removal and the three canonical participants without assigning every reaction to every strain. Authorized full text and scoped extension research remain necessary before adding causal links.
