Isolation and characterisation of antifungal compounds from lactic acid bacteria and their application in wheat and gluten-free bread
As part of the “free-from” trend, biopreservation for bread products has increasingly become important to prevent spoilage since artificial preservatives are more and more rejected by consumers. A literature review conducted as part of this thesis revealed that the evaluation of more suitable …

Isolation of Antifungal Lactic Acid Bacteria from Food Sources and Their Use to Inhibit Mold Growth in Cheese
… is lost every year due to mold contamination. Biopreservation, which is the use of biological entities (microbes) and their metabolites to suppress microbial spoilage instead of chemical preservatives has lately gained increasing interest. Lactic acid bacteria (LAB) have the potential for use …

Novel Cryoprotective agents to improve the quality of cryopreserved mammalian cells
… is a promising approach to long-term biopreservation of living cells, tissues and organs. The use of cryoprotective agents (CPAs) in combination with extremely low temperatures is mandatory for optimum biopreservation. CPAs (e.g., glycerol, trehalose, dimethyl sulphoxide (DMSO)), …

Lactic acid bacteria fermentation of wort as a tool to add functionality in malting, brewing and novel beverages
… the investigation of several strains of LAB for biopreservation using in vitro and in situ studies, as well as for acidification of wort to be applied during sour brewing and as novel beverages. The impact of bacterial carboxylic acids, with emphasis on phenolic antifungal compounds, was assessed …
