“…In 1992, Kim and Gee published a work in "Water Environmental Research" prospecting the relevant rule of biotechnology for the treatment of hazardous wastes (Kim & Gee, 1992). Approximately 30 years later, we know that bacteria can support the sustainable implementation of a circular economy by increasing the performances of wastewater treatments for water reuse (Choudri, Al-Awadhi, Charabi, & Al-Nasiri, 2020); controlling GHG emissions by the capture and/or sequestration of CO 2 or reducing its global pressures in the atmosphere (Koh & Shaw, 2018); producing hydrogen, biomethane and different forms of bioenergy (Sheehan et al, 2018); and introducing other amazing solutions with promising applications for global sustainability (Chang, DiGiovanni, & Mei, 2019).…”
