Visite d'Izabela Michalak au Laboratoire LBCM

Visite d'Izabela Michalak au Laboratoire de Biotechnologie et Chimie MarinesIzabela Michalak était au Laboratoire de Biotechnologie et Chimie Marines du 13 au 22 septembre 2018.

Dr. Izabela Michalak from Wrocław University of Science and Technology (Wrocław, Poland) attended in a short-term scientific training in the University of Southern Brittany (Laboratory of Marine Biotechnology and Chemistry, LBCM) in September.


Izabela has been working for several years on marine algae and applications in bioremediation and agriculture. She is known for two famous publications:

Michalak, I., & Chojnacka, K. (2015). Algae as production systems of bioactive compounds. Engineering in Life Sciences, 15(2), 160-176.

Michalak, I., Tuhy, Ł., & Chojnacka, K. (2015). Seaweed extract by microwave assisted extraction as plant growth biostimulant. Open Chemistry, 13(1).


During the stay Izabela Michalak participated in lectures, research and scientific meetings.



Izabela Michalak presented three lectures to the Master 1 and 2 students from the Laboratory of Marine Biotechnology and Chemistry in UBS in Lorient (17.09.2018):

  • Algae and algae-based products – potential applications
  • Algal extracts – potential applications
  • Biosorption of metal ions by biomass in practice



Scientific meetings

Izabela Michalak participated in several scientific meetings

  • Professor Chrystèle Dufau – a Director of Master 2 Programme at UBS
  • PhD Jean-Pascal Bergé – the CEO of BioThoT, a company dedicated to assist industry for a better use of their biomass
  • Jean-Philippe Kucma – the CEO of NEWONAT (, a company specialized in the extraction of different plant materials, using several extraction techniques (e.g. supercritical fluid extraction, ultrasound assisted extraction etc.,), purification of extracts and their chemical analysis using chromatography (GC, HPLC, TLC)



During a short scientific-training, Izabela Michalak participated in the excursion/classes to Hoëdic island (2 days) which aimed at the exploration, identification and collection of seaweeds with students

She collected brown seaweeds – Ascophyllum nodosum, Fucus serratus and Fucus vesiculosus in Arradon (Brittany, France) and prepared them for the extraction process

Izabela was familiarized with the subject of a research conducted in the team of Professor Nathalie Bourgougnon – presentations of PhD student: Shareen A ABDUL MALIK concerning active substances from Halymenia floresia (Clemente) C. Agardh used as antifouling products in aquaculture and post-doc: Hugo Cortes Pliego concerning the extraction of glycoproteins from green seaweeds – Ulva lactuca. She was acquainted with the extraction of glycoproteins from green seaweeds – Ulva lactuca (post-doc Hugo Cortes Pliego) and by Professor Laurent Vandanjonwith several techniques used in the laboratory, e.g., FTIR, freeze-drying.


She was acquainted by Professor Nathalie Bourgougnon with the analysis of chemical composition of collected brown seaweeds (for example: protein, sugars, ash, phenols, sulfate, uronics, lipids and antioxidant activity), extraction of alginates and antiviral evaluation of algal extracts and discussed with the research team of Professor Nathalie Bourgougnon about methods of utilization of algal biomass collected from the natural environment


Future perspectives

During a short scientific-training, Izabela Michalak discussed also with the research team about possible publications/join research projects aiming the use/valorisation of algae collected from the seaside. She worked together with me on the proposal for the “Interdisciplinary School for the blue planet (ISblue)” for the Master student from UBS, who would like to participate in the research in Poland.
