    Environmental Consortium Containing Pseudomonas and Bacillus Species Synergistically Degrades Polyethylene Terephthalate Plastic

    While several research groups are utilizing purified enzymes to break down postconsumer PET to the monomers TPA and ethylene glycol to produce new PET products, here, we present a group of five soil bacteria in culture that are able to partially degrade this polymer. To date, mixed Pseudomonas spp. and Bacillus spp. biodegradation of PET has not been described, and this work highlights the possibility of using...

    Cross-Feeding between Members of Thauera spp. and Rhodococcus spp. Drives Quinoline-Denitrifying Degradation in a Hypoxic Bioreactor

    We experimentally verified that the second most abundant taxon, Rhodococcus, played a role in degrading quinoline to 2-hydroxyquinoline, while the most abundant taxon, Thauera, degraded 2-hydroxyquinoline. Metabolites from Thauera further served to provide metabolites for Rhodococcus. Hence, an ecological guild composed of two isolates was assembled, revealing the different roles that keystone...

    Isolation and Characterization of Ochrobactrum tritici for Penicillin V Potassium Degradation

    Substantial concentrations of penicillin V potassium (PVK) have been found in the environment, which may pose potential threats to human health and contribute to the emergence of penicillin-resistant bacterial strains. In this study, antibiotic-degrading bacterial strains for PVK were isolated from sludge and characterized. Ochrobactrum tritici was selected for the...
