“…The genus Aeromonas consists of oxidase positive, facultatively anaerobic, polarly flagellated or nonmotile, straight rods which ferment glucose with or without the production of gas (18,19,41). One species carries out a 2,3-butyleneglycol fermentation.…”

Taxonomy of Marine Bacteria: the Genus Beneckea

One-hundred-and-forty-five isolates of marine origin were submitted to an extensive physiological, nutritional, and morphological characterization. All strains were gram-negative, facultatively anaerobic, straight or curved rods which were motile by means of flagella. Glucose was fermented with the production of acid but no gas. Sodium but no organic growth factors were required. None of the strains were able to denitrify or fix molecular nitrogen. The results of nutritional and physiological tests were submitted to a numerical analysis. On the basis of phenotypic similarity, nine groups were established. These groups could be distinguished from one another by multiple, unrelated, phenotypic traits. Six groups which had deoxyribonucleic acid (DNA) containing 45 to 48 moles per cent guanine plus cytosine (GC) were assigned to a redefined genus Beneckea. All of the strains in this genus, when grown in liquid medium, had a single, polar flagellum. When grown on a solid medium, many strains had peritrichous flagella. Two groups were similar to previously described species and were designated B. alginolytica and B. natriegens. The remaining four groups were designated B. campbellii, B. neptuna, B. nereida, and B. pelagia. An additional group of phenotypically similar strains having the properties of the genus Beneckea was not included in the numerical analysis. These strains were readily separable from species of this genus and were designated B. parahaemolytica. Of the remaining groups, one was identified as Photobacterium flscheri. The other group (B-2) which had about 41 moles % GC content in its DNA could not be placed into existing genera. 268on July 3, 2020 by guest http://jb.asm.org/ Downloaded fromAfter 48 hr of incubation, the plates were flooded with acidic mercuric chloride (52).

SUNIXARY. Esterases of strains of Vibrio cholerae, V . parahuemolyticus, noncholera and marine vibrios were examined by electrophoresis in starch gels. The enzyme patterns indicated a relative homogeneity occurring amongst the strains. No separation of the genus Vibrio into subgroups corresponding t o the E l Tor, classical cholera or noncholera groupings was noted. Overall deoxyribonucleic acid base composition for the Vibrio spp. ranged from 44-49 mol% guanine + cytosine, with the marine vibrios lowest in guanine $-cytosine content. Enzyme patterns for cholera vibrios isolated during very recent epidemics were identical to those of established laboratory strains, suggesting a marked stability of the esterase system for V . cholerae.

“…The type strains of the latter three species were strains NCIB 2581, NCIB 8194 (= ATCC 6972), and NCIB 2582 (= ATCC 14636), respectively (41,56). Later, it was shown that classification of these organisms as Vibrio species was erroneous, not only because of their aberrant physiological and morphological characteristics (11,14,29,35,52,54) but also because the deoxyribonucleic acid (DNA) base compositions of these strains are considerably higher than those of other Vibrio species (12, 53). Galarneault and Leifson (29) proposed the name 'Lophomonas alcaligenes" for a group of gram-negative, rod-shaped, lophotrichous bacteria which did not attack carbohydrates either fermentatively or oxidatively .…”

The historical and present taxonomic and nomenclatural status of the following taxa were examined: "Vibrio terngenus" Gunther 1894, "Vibrio percolans" Mudd and Warren 1923, "Vibrio alcaligenes" Lehmann and rev. An extensive phenotypic description of C . terrigena is given, and this species can be differentiated from P . acidovorans and P . testosteroni. "Achromobacter cystinovorum" NCIB 4854 is misnamed and was found to be very elosely related to P . acidoovorans. "V. alcaligenes" NCTC 9239 was found to be misnamed and is closely related to Pseudomonas diminuta, which is itself inappropriately retained in the genus Pseudomonas. The classification of "V. cuneatus" NCIB 8194 as Pseudomonas jluorescens is confirmed. "C. compransoris" DSM 1231 and "V. cyclosites" ATCC 14635 (the so-called synonymous strain of "V. cyclosites" NCIB 2581) are definitely not members of C . terrigena. These two strains differ considerably from each other, as well as from all of the other strains investigated; their exact taxonomic position is unknown.
