I am almost at the end of my Ph.D. that dealt with the enzymatic degradation of sugar beet pulp. Sugar beet pulp is a by-product of the sugar production in Europe and is considered is valuable feedstock for biorefinery. Before it can be used in biorefinery it has to be degraded either thermophysically or biochemically with the help of enzymes. In my project I mainly worked on the purification and characterisation of pectin degrading enyzmes from the fungus Chrysosporium lucknowense.
As a student worker I was busy with basic lab works, the growth of arabidopsis hypocotyls and the analysis of their cell walls. To this end, I extracted cell wall material and performed an enzymatic degradation of the cell wall material. The degradation products were analysed by MALDI-TOF mass spectroscopy.
During my time at the blood service I was mainly involved in the registration and examination of the blood donors. I was also in charge of the maintenance and preparation of the equipment for blood and blood plasma donation.
