Description

Are you interested in bacteria that can help us reduce climate gases? We are looking for PhD candidates who will join us in pushing the frontier within microbial ecophysiology!

PhD scholarship within environmental microbiology About the position

The Faculty of Chemistry, Biotechnology and Food Science (KBM) at the Norwegian University of Life Sciences (NMBU) has two vacant 3-year PhD–positions within microbial ecology and environmental microbiology. The successful candidate will be anchored in the research group Microbial Ecology and Physiology at KBM (https: // www. nmbu.no/fakultet/kbm/forskning/forskningsgrupper/environmental- microbiology) which is part of the NMBU Nitrogen group (https: // www. nmbu.no/en/research/groups/nitrogen). The NMBU-Nitrogen Group is mid-sized and has members from several countries. The group is at the international forefront within studies of microbial N-transformations in natural and engineered systems, and our ultimate aim is to contribute to reduced climate gas emissions from agriculture and industry. Our approach is to integrate basic and applied research on laboratory- to field scale. This has opened biotechnological avenues for reducing emissions, and we are currently exploring a range of options together with biogas industries and (bio)fertilizer companies.

The two PhD positions are connected to a newly started research project “Revealing effects of starvation and oxidative stress on denitrifying bacteria: a basis for novel N2O mitigation and industrial applications”.

The last reports from IPCC (the Intergovernmental Panel on Climate Change) describe steadily increasing emission of N2O, a potent greenhouse gas and in addition the main destructor of the stratospheric ozone. Denitrifying bacteria are responsible for the main part of the global N2O emissions from soils. Many denitrifying bacteria capable of both producing and consuming N2O, and the amounts that are emitted depend on their regulatory biology.

Although much is known about this regulation, the current knowledge is mostly based on laboratory studies of organisms growing under optimal conditions. Surprisingly little is known about the regulation of denitrification in bacteria living under natural conditions, where they starve most of the time and are exposed to fluctuating oxygen concentrations that may harm the enzymes.

In this project we will investigate how these stressors affect the regulation of N2O emissions. We will do detailed studies of diverse bacteria in pure cultures. Studies of soil microbiomes may also be included. The ultimate aim is to understand regulation of denitrification in natural environments and to strengthen ongoing attempts to bioengineer soil communities to reduce the emissions of N2O. One of the tasks will be to develop CRISPRi-based molecular tools, which will be an invaluable asset for studies of oxidative stress and damage on proteins. Other tools that will be used include transcription analyses, bioassays and (meta)genomics/proteomics, as well as our unique robotized systems for monitoring gas kinetics in denitrifying bacteria. The results will add new, basic knowledge to our understanding of the biogeochemical nitrogen cycle and will strengthen our ongoing development of novel methods for N2O mitigation. The PhD candidates will work in a stimulating research environment and collaborate with several PhD students and post-doctoral researchers working with adjacent projects.

Main tasks

As part of the project, the candidate will study the respiratory physiology of denitrifying prokaryotes (mainly bacteria) through:

  • Gas kinetics and gene expression in new isolates, model organism(s) and mutants under a range of conditions
  • Proteomics of denitrifying cultures
  • Confocal microscopy
  • Genomics/bioinformatics and possibly meta-omics analyses
  • Molecular manipulations (including CRISPRi) of selected strains
  • The successful candidate is expected to enter a plan for the progress of the work towards a PhD degree during the first months of the appointment, with a view to completing a doctorate within the PhD scholarship period.
