Felizitas Bajerski and her colleagues reviewed the potential risks for microbial contaminations in liquid nitrogen tanks used to store biological material such as microorganisms or human, animal or plant cells. Potential contaminants and their sources are identified and the researchers provide options to reduce the risk of microbial contamination of stored bioresources.
In order to monitor the awareness of contamination in cryobanking a survey was conducted. In total 34 biobanks from five continents answered questions related to their cryobanking procedures.
Furthermore, the authors developed a novel risk assessment spreadsheet that can be used to optimize a biobank’s quality management.
