 Uni Gdansk biomass “case”: from biomass to biogas 

The Polish researchers at University of Gdansk are developing a technology for microalgal biomass production.

The Organization

The case “Uni Gdansk-Biomass” is a group of researchers studying various aspects of microalgal ecophysiology and genetics at the Institute of Oceanography, University of Gdańsk. The team consists of highly qualified scientific staff having many years of experience in the cultivation of microalgae and maintaining a unique collection of Baltic algae strains. The core people are:

  • Case owner - Marek Klin, PhD student
  • Adam Latała, Professor
  • Filip Pniewski, PhD
  • Aleksandra Zgrundo, PhD

The idea

By combining the features of rapid growth of algae and their susceptibility to stress factors, we gain access to a great source of biomass produced during photosynthesis, our greatest natural ally in capturing atmospheric carbon dioxide and its transformation into a source of energy.

Among the biofuels possible to be produced from algal biomass, biogas fulfills the conditions of a most attractive fuel in the region. Also, it is easily convertible into electrical energy, the basic power supply for modern technologies. Anaerobic digestion by means of which biogas is produced depends on the biochemical composition of the substrate used. Research shows that the biochemical composition of algae is strictly determined by culturing conditions and can be improved (i.e. energetic lipids content) by the controlled application of stress factors.

Despite its potential, the performance and efficiency of microalgal biomass as a feedstock is not yet sufficiently tested. Given the rapidly advancing technology of cultivation and possibility of costs reduction using environmental waters or wastewater, reconsideration of microalgae biomass as a biogas substrate is highly recommended.

Progress of the case „Uni Gdansk-Biomass” within the ALLIANCE mentoring:

  • New strains have been isolated and their growth characteristics examined.
  • Further biochemical analyses are ongoing to predict the fermentation potential of obtained biomass (carbohydrates and proteins content).

The ALLIANCE is a catalyst for cooperation between individuals willing to move forward with interesting projects in blue biotechnology. Personally, it gave me the chance to get contacts and gain experience during internship which I would never have got as a single scientist." -

The allies

The ALLIANCE mentors of the case are University of Gdansk (UG) and Danish Technological Institute (DTI).

The current needs are:

  • Batch Biochemical Methane Potential tests of biomass from single or mixed strains.
  • Cumulative methane production estimation over time.
  • Chemical analysis of a mixture of gases produced on biomass.
