Antimicrobial Materials from Cellulose Using Environmentally Friendly Techniques

Published Nov 21, 2018

Anna Ottenhall will be defending her dissertation "Antimicrobial Materials from Cellulose Using Environmentally Friendly Techniques" on 7 December 2018.

What is your dissertation about?

It is about more environmentally friendly ways to prevent microbial growth on biobased materials as well as how to remove bacteria from water using biobased filters.

Does it have any connection to KTH’s sustainability work and the global sustainable development goals?

Yes, I recently presented some of my work at KTH Sustainability Research Day. One of the UN goals for sustainable development is clean water for all and the return to a more biobased society will require techniques to prevent microbial growth on materials made from biodegradable resources.

How can your results be used in the future?

The way to make bacteria adsorbing materials using cationic polyelectrolytes have the potential to be used for different applications where we want to trap and remove bacteria. One goal we have had is to use it for water purification in the future. Another research highlight from the thesis is the good antifungal effect chitosan had in cellulosic fiber foam materials.
