My current research interest is the microbiology of dairy value chain. I am working as a Postdoc researcher at Åse Lundh lab. There are multiple on-going projects with the overall aim to increase the long-term profitability of the Swedish cheese manufacturing industry by reducing the costly variation in time needed for the ripening process, including: 1) recruiting dairy farms and characterizing their production systems through detailed questionnaires and visits on farm; 2) investigating raw milk properties including microbial community; 3) analysing the the impact of farm management on the microbial community of raw milk; 4) selecting clusters of farms with unique raw milk properties including microbial community to perform full scale cheese making trial; 5) investigating the flow of flavor producing Lactobacilli from forages to final cheese, the effect of botanical composition and ensiling.
Industrial PhD project: the origin of the flavour producing Lactobacilli; the effect of botanical composition of forages as well as the process of ensiling on the occurrence and activity of lactobacilli in the resulting cheese, as co-supervisor. PhD-student: Thomas M. Eliasson
Master project: Degradation of straw and cellulose in biogas digesters- efficiency and community structure, as main supervisor. Master student: Tong Liu.
Master project: DNA based analyses of microbiota in fat fraction of raw milk, as co-supervisor. Master student: Caroline Blänning.
Exchange project: Visualization of fluorescent Lactobacillus reuteri in milk using epifluorescence microscopy, as co-supervisor. Exchange student: Wanigasuriya, W.A. Guwanth Indramal
Exchange project: Identification of microbial composition of Swedish hard cheese by MALDI ToF mass spectrometry, as co-supervisor. Exchange student: Dissanayake, R.G. Thilini Nuwandhara
