How does rhodopsin light energy harvesting influence the ecology of marine bacteria?
Our research projects in marine microbiology and molecular biology are focused on complementary aspects of marine microbial ecology.
The core of several of our research projects in microbial oceanography is our long term time-series station at the Linnaeus Microbial Observatory LMO. We have carried out sampling here since a total of sampling times until March , and during samples are collected at LMO every second week.

A buoy at the station collects continuous measurements of e. The collected samples fall into one or more of the following categories of study: Bacteria, Phytoplankton, Phages, Zooplankton and Bioinformatics. Novel photosystems in marine bacteria, based on the light harvesting membrane protein proteorhodopsin, were recently discovered to be widespread and abundant in the oceans. Rhodopsins allow bacterioplankton to harvest energy from sunlight making them photoheterotrophic This challenges the traditional view that autotrophic phytoplankton are the only organisms that fix CO2 in the surface ocean.
Our research explores the genetic diversity, physiology and ecology of rhodopsins in marine bacteria. We study the spatiotemporal distribution of different rhodopsins in the sea, carry out laboratory experiments with rhodopsin-containing bacterial isolates and natural assemblages, and determine which metabolic pathways are affected by light. We thereby broadly study how rhodopsin-containing marine bacteria use light as an energy source to promote fitness in terms of improving growth and survival.
Bacterioplankton are highly abundant in the pelagic waters of the Baltic Sea where they are key drivers of the cycling of nutrients. Their high turnover rates and short generation times allow them to respond rapidly and in a sensitive manner to environmental changes. Still, these organisms are not yet used as indicators of good environmental status GES and only in parts are included in biogeochemical or climate change models.

The project combines field studies, experiments, next-generation sequencing, bioinformatics and modeling to reach its main goal: to establishing a capacity to reliably deduce Baltic Sea environmental status based on indicators reflecting the biodiversity and genetic functional profiles of microbes in seawater samples.
Briefly, in laboratory experiments we exposed bacteria to pollutants in different growth phases, and monitored bacterial abundance and bacterial production, and collected samples for gene expression analysis. We thus hope to characterize how different hazardous compounds affect metabolic pathways in marine bacteria. This project investigates the molecular mechanisms employed by marine bacteria in the coastal surface ocean to carry out cycling of dissolved organic carbon compounds.
This project investigates marine seasonal succession dynamics of bacterioplankton communities in collaboration with Prof. Peter Tiselius University of Gothenburg. Coexistence of microbes like bacteria, virus and unicellular eukaryotes and protists is the norm in nature and different species occupy what may appear to be similar ecological niches.
Interactions between microbial species in terms of mutualism, commensalism or parasitism, is the result of a long co-evolution. Protista, unicellular organisms, may be potential promoters of bacterial survival, persistence and growth in the marine environment, offering shelter, site for replication and dissemination. Previous research has shown that interactions between bacteria and Protista could trigger bacterial virulence or pathogenicity.

Our current research focuses on marine bacteria and their diverse interactions with different protozoa and algae, with the aim to evaluate the molecular basis for and consequences of coexistence. Such studies could provide important insights into the regulation of biogeochemical processes driven by microbes and answer questions like: Is coexistence important for pathogenicity?
Do bacteria respond to the decline of algal blooms or do they cause them? We use a series of established and state-of-the-art methods in microbial ecology to determine the activity of bacteria in the water column. This is linked with genetic analyses at the DNA and RNA level genomics and transcriptomics, respectively to investigate the molecular mechanisms that determine the ecological function and success of different bacteria in the marine environment.
Moreover, we use comparative proteome analysis on natural bacterial assemblage and on bacterial isolates to examine similarities and differences in metabolism and physiology of genome-sequenced and representative marine bacteria under various growth limiting conditions.
