“…The relative abundance of Proteobacteria increased during the first seven days after BAC administration and then decreased. This is consistent with the rapid BAC degradation in the initial period of incubation, implying that certain species in Proteobacteria could contribute to the BAC degradation ( Das et al., 2021 ; Kidd et al., 2021 ; Mohapatra and Phale, 2021 ). The relative abundance of Crenarchaeota was significantly higher than that of day 0 except for day 7, and its abundance was positively correlated with the concentration of BAC (Appendix A Fig.…”

“…The presence of RND efflux pumps and other antimicrobial resistance pathways can then confer to the bacterial microbiota the arsenal to adapt to the lichen [37]. Furthermore, the RND efflux pumps are involved in Polyaromatic Hydrocarbons (PAHs) degradation [78, 79]; a group of organic compounds which are highly toxic and contaminate terrestrial and aquatic environments. RND-type efflux pump (EmhABC) has been described previously [78, 80] as extruding hydrophobic antibiotics and PAHs, including phenanthrene, anthracene, and fluoranthene [78, 81].…”

As rock-inhabitants, lichens are exposed to extreme and fluctuating abiotic conditions associated with poor sources of nutriments. These extreme conditions confer to lichens the unique ability to develop protective mechanisms. Consequently, lichen-associated microbes disclose highly versatile lifestyles and ecological plasticity, enabling them to withstand extreme environments. Because of their ability to grow on poor and extreme habitats, bacteria associated with lichens can tolerate a wide range of pollutants and on the other hand secrete antimicrobial compounds. In addition, lichen-associated bacteria were described to harbor ecological functions crucial for the evolution of the lichen holobiont. Nevertheless, the ecological features of lichen-associated microbes are still underestimated. To explore the untapped ecological diversity of lichen-associated bacteria, we adopted a novel culturomic approach on the crustose lichen Rhizocarpon geographicum. We sampled R. geographicum in French habitats exposed to oil spill and we combined 9 culturing methods with 16S rRNA sequencing to capture the largest bacterial diversity. A deep functional analysis of the lichen-associated bacterial collection showed the presence of a set of bacterial strains resistant to a wide range of antibiotics and displaying tolerance to Persistent Organic Pollutants (POP). Our study is a starting point to explore the ecological features of the lichen microbiota.

“…Numerous evidences have demonstrated that the propagation of ARGs and ARB in the environments could be promoted by selective factors including antibiotic (Ben et al 2019;Zhou et al 2022), disinfectant (Kampf 2018), pesticide (Ramakrishnan et al 2019), and heavy metals (Poole 2017). More recently, the influences of organic matters (especially polyaromatic hydrocarbons, PAHs) on the evolution of antibiotic resistance in the environments have attracted growing attention (Das et al 2021;Maurya et al 2021;Sun et al 2015;Tan et al 2019;Wang et al 2017a). A metagenomic study showed that the abundances of ARGs in the PAH-contaminated soils collected from a petrochemical plant were approximately 15 times higher than those in the background sites (Chen et al 2017).…”

Accumulation of toxic organic has posed a substantial pressure on the proliferation of bacterial resistance. While aromatic organics have been demonstrated to enhance the antibiotic resistance in bacteria, no information is yet available on the effects of non-aromatic organics on the variations of bacterial resistance. Here, we investigated the effects of a typical ketone (i.e., methylisobutanone (MIBK)) on the variations of antibiotic resistance in Escherichia coli (E. coli). The results showed that the growth of resistant E. coli under environmental concentration of 50 μg/L MIBK was firstly inhibited as explained by the transient disruption in the cell membrane and then recovered possibly due to the reactive oxygen species. Exposure to 50 μg/L MIBK gradually raised the abundance of representative resistance gene (ampR) in E. coli. In contrast, the high concentration of 50 mg/L MIBK continuously inhibited the growth of resistant E. coli by disrupting cell membrane and notably promoted the proliferation of ampR through enhancing the horizontal transformation and up-regulating the expression of efflux pump gene. These findings provided the first evidence for the evolution of bacterial resistance in response to ketone organics.
