Microorganisms exhibiting a high degree of phenotypic and genetic similarity; a pragmatic approach to demarcating “microbial species” using molecular biology tools has been 97% 16S rRNA sequence identity or 70% genome identity based on DNA-DNA hybridization; thus, microbial species are often defined by operational characteristics (operational taxonomic unit). The microbial species concept is still a matter of controversy. See entry “ Microbial Communities, Structure, and Function” for further reading.
