Mechanistic Understanding of Gordonia sp. in Biodesulfurization of Organosulfur Compounds

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.

Emissions from human activities contribute to air pollution, global warming, and environmental degradation. These effects can harm human health and ecosystems, underscoring the importance of sustainable practices to mitigate the impact of emissions on the environment. By the time on the first exploration of reservoirs and first design contracts dates of refineries, there are many challenges appeared on the health, safety, and environment by conduction of the oil such as the higher contents of sulfur, nitrogen, oxygen, halogen, metals, and aromatics. There are many side effects on the human health starting from the simple to the malignant diseases such as cancer. Also, the safety of equipment and catalysts are affected by the presence of high content of these impurities in oils by many phenomena such as corrosion, erosion, and poisoning. In this study, microorganisms' colony has been isolated from Amara crude oil by using 9k medium (ATCC 2436). It was found that this colony has the ability to make bio desulfurization (BDS) of crude oil from 4.4 to 3.845 %. Also, it was found that this isolated colony upgraded the oil in improvement API-density.

Consequently, lichen-associated microbes disclose highly versatile lifestyles and ecological plasticity, enabling them to withstand extreme environments.

In addition, lichen-associated bacteria have been 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 spills, and we combined nine culturing methods with 16S rRNA sequencing to capture the greatest 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 (POPs).
