Aprotocolforcleaningandreusingthelarge25x25cmplates
We regularly reuse our large 25x25 cm plating trays; initially, however, we were plagued by gross microbiological contamination when reusing the trays. Various combinations of cleaning with a laboratory dishwasher, ethyl alcohol, and UV irradiation still resulted in a lot of contamination, particularly yeast. After examining several disinfection methods, the following procedure was determined to be the simplest and m......阅读全文
