New doctor in Łukasiewicz - ITD
On July 8th, 2021, based on successful defense of the doctoral dissertation entitled "Caffeine as a potential fungicide for wood protection", the Discipline Council for Forest Sciences adopted a resolution to award Patrycja Kwaśniewska-Sip, MSc (Eng), from the Air Quality Investigation Department of the Łukasiewicz – ITD with the doctoral degree in agricultural sciences.
The doctoral thesis was carried out at the Poznań University of Life Sciences. The supervisor was Assoc. Prof. Grzegorz Cofta, PhD (Eng) from the Faculty of Forestry and Wood Technology of the Poznań University of Life Sciences, and Monika Bartkowiak, PhD (Eng) from the same faculty was the auxiliary supervisor. Assoc. Prof. Joanna Kurczewska, PhD from the Faculty of Chemistry of the Adam Mickiewicz University and Piotr Witomski, DSc from the Faculty of Wood Technology of the Warsaw University of Life Sciences were appointed as reviewers.
The thesis was concerned with the use of a natural compound – caffeine – as an active ingredient in wood preservatives, inhibiting the growth of selected wood-inhabiting fungi.
The use of wood preservatives based on products of natural origin as an alternative to chemical biocides is a rapidly developing field of study. As part of the doctoral dissertation, fungistatic properties of caffeine against wood-inhabiting fungi were demonstrated, as well as chemical characteristics of interactions between caffeine and wood material, optimization of the parameters of the caffeine-based preparation for wood impregnation, and a complex preparation for wood impregnation containing active substances and compounds preventing washing out was developed. It should be emphasized that caffeine is a pro-ecological substance, obtained from readily available natural raw materials, which are a renewable source. Moreover – it can be obtained from the food industry by-products.
Congratulations and best wishes for continued success in scientific development!
