Isolation and Genome Sequencing of Novel Phototrophic Bacteria from Activated Sludge and Intertidal Sediments

Aarhus University, Dept. of Environmental Science


We are seeking one or two master students to work on this project.

--Project description--
We are living in a microbial planet teeming with tiny single-celled microorganisms, which play a critical role in keeping all ecosystems healthy and our environments sustainable. Among the extremely high biodiversity of microorganisms, phototrophic bacteria are a group of fundamental ecological roles because of its unique capability of harvesting sunlight. Only a few bacterial groups are able to perform photosynthesis. Recently, we added a new member to this list, i.e. “Phototrophic Gemmatimonadetes Bacteria (PGB).” Still we know very little about PGB. Biomarker gene surveys suggested PGB are widely distributed in the environments, especially enriched in activated sludge and intertidal sediments. We set out to isolate them from a Roskilde wastewater treatment plant and from the intertidal sediments of western coast of Denmark and sequence their genomes. The goal of this project is to gain more insights into PGB’s evolutionary history and their genomic basis of performing photosynthesis, which may facilitate future genome engineering of their photosystems.

--Work environment--
The project will be carried out in the Environmental Microbiology and Biotechnology Section in Department of Environmental Science, Aarhus University, located in the Roskilde campus (link). The section features an international research environment, equipped with cutting-edge genome sequencers, high-end bioinformatics servers and all essential facilities for environmental microbiology research. The student will be supervised by Dr. Yonghui Zeng and Prof. Lars H. Hansen.

The student will be trained towards an environmental microbiologist with skills in fieldwork, bacterial cultivation, molecular identification of isolates, genome sequencing, and DNA sequence data analysis. The successful results may lead to authored publications in professional journals.

Nothing but “Curiosity for a microbial world” and “Spirit of spotting a needle in a haystack”.
