  • 🧍 In 1940, B. Elazari-Volcani described "Flavobacterium (Halobacterium) maris-mortui (sic)" (B. Elazari-Volcani, Studies on the microflora of the Dead Sea. Thesis, Hebrew Univ., Jerusalem, 1940, V and 48) [1]. Publication: Elazari-Volcani B. Genus XII. Halobacterium Elazari-Volcani, 1940.

  • 🧍 Later this author dropped the "Elazari" from his family name and added the E. as an initial [2]. As co-author of the paper by Oren et al. 1990, he requested that his name be cited as Volcani [2]. Consequently, in the "List of Prokaryotic names with Standing in Nomenclature", Haloarcula marismortui is cited as Haloarcula marismortui (ex Volcani 1940) Oren et al. 1990. — Oren A. Personal communication, 2004-12-11.
