From Efficiency to Resilience : Systemic Change towards Sustainability after the COVID-19 Pandemic
The COVID-19 pandemic has revealed the vulnerability of current socio-economic systems and thrown into question the dominant global paradigm geared towards short-term financial efficiency. Although it has been acknowledged for several decades that this paradigm has detrimental impacts on the climate, the environment and global welfare, the pandemic has now offered a grim ‘rehearsal round’ for more serious crises that are to come with the accelerating climate emergency, loss of biodiversity and growing human inequalities. Along with worsening climate change, there are looming risks for mass migrations and armed conflicts as habitats capable of supporting human wellbeing become scarce, such a…
Methylophaga and Hyphomicrobium can be used as target genera in monitoring saline water methanol-utilizing denitrification.
Abstract Which bacterial taxonomic groups can be used in monitoring saline water methanol-utilizing denitrification and whether nitrate is transformed into N2 in the process are unclear. Therefore, methylotrophic bacterial communities of two efficiently functioning (nitrate/nitrite reduction was 63–96 %) tropical and cool seawater reactors at a public aquarium were investigated with clone library analysis and 454 pyrosequencing of the 16S rRNA genes. Transformation of nitrate into N2 was confirmed using 15N labeling in incubation of carrier material from the tropical reactor. Combining the data with previous study results, Methylophaga and Hyphomicrobium were determined to be suitable targe…
