Patent ID: 11512279

Abstract:
A system for generating and using an assay key comprising growth conditions for a set of microorganisms for a set of diverse QAC-based culture media under a variety of incubation conditions known to modulate the effect of QAC on growth of some microorganisms in the set. Each culture medium is characterized by a pH and includes one or more QACs and one or more growth supplements. The set of culture media includes media comprising various combinations of pH, QAC type, QAC concentration, growth supplement type, and growth supplement concentration. The assay key can be used to identify a microorganism by inoculating a variety of growth media within the key and incubating the inoculated media under conditions within the key and comparing the resulting pattern of microorganism growth across the media and conditions with growth patterns for various known microorganisms across the media and conditions that are within the key.
