<Aharon Oren> is a <microbiologist> and coauthor of the 2022 revision of the International Code of Nomenclature of Prokaryotes, published in 2023. This work contributes to <prokaryotic nomenclature>: shared rules that let researchers apply and track names consistently.<International Code of Nomenclature of Prokaryotes. Prokaryotic Code (2022 Revision) by Aharon Oren and others>[Original byline and Preface: preparation and publication of the revision]{ref}
One useful technical distinction concerns a <strain (biology)>. The code describes it through descent from one isolation in <pure culture>, while a culture is a population at a particular place and time. Serially transferring material into fresh vessels can therefore produce several cultures of the same <strain (biology)>.<International Code of Nomenclature of Prokaryotes. Prokaryotic Code (2022 Revision) by Aharon Oren and others>[Appendix 10, section A(3), Use of other terms: culture and strain]{ref}
The example shows why a laboratory sample label and a biological identity are different kinds of information. Two vessel labels do not by themselves establish two independent strains, and descent from one isolation need not establish descent from one original <biological cell>.
