The most commonly accepted definition is the polyphasic species definition, which takes into account both phenotypic and genetic differences. [90] However, a quicker diagnostic ad hoc threshold to separate species is less than 70% DNA–DNA hybridisation, [ 91 ] which corresponds to less than 97% 16S DNA sequence identity. [ 92 ]
