The killing of bacteria on surfaces by two types
of UV sources generated by microwave radiation is
described. In both cases, UV radiation is produced by gasdischarge
electrodeless lamps (Ar/Hg) excited by microwaves
generated by a power supply fr... Read More about Killing bacteria present on surfaces in films or in droplets using microwave UV lamps.

A new short-term toxicity assay using Aspergillus awamori with recombinant aequorin gene (2005)
Journal Article
Kozlova, O., Zwinderman, M., & Christofi, N. (2005). A new short-term toxicity assay using Aspergillus awamori with recombinant aequorin gene. BMC Microbiology, 5, Article 40. https://doi.org/10.1186/1471-2180-5-40

Background
Most currently available short-term toxicity assays are based on bacterial cells. Therefore there is a need for novel eukaryotic microbial bioassays that will be relevant to higher eukaryotes such as animals and plants. Ca2+ is a universa...

A laboratory model nitrifying activated sludge plant treating OECD synthetic sewage was designed and constructed by each of three laboratories in Germany, Scotland and Spain in order to produce a sludge inoculum for 5 rapid toxicity bioassays. The pl... Read More about Congruence in the performance of model nitrifying activated sludge plants located in Germany, Scotland and Spain.

Five rapid direct toxicity assessment methods were used in three European partner countries to determine the toxicity of single toxicants, mixed toxicants and real industrial wastes. The final aim was to protect microbial degradation of organic waste...
