145个海洋来源的分离物被提交给广泛的生理、营养和形态特征。所有菌株均为革兰氏阴性、兼性厌氧、直杆或弯曲杆状，鞭毛可移动。葡萄糖在产酸但不产气的情况下发酵。钠，但不需要有机生长因子。这些菌株都不能反硝化或固定分子氮。营养和生理测试的结果被提交给数值分析。在表型相似性的基础上，建立了9个类群。这些群体可以通过多个无关的表型特征相互区分。六组脱氧核糖核酸(DNA)含有45-48摩尔百分比的鸟嘌呤和胞嘧啶(GC)，被分配到重新定义的Beneckea属。当在液体介质中生长时，该属的所有菌株都有一个单一的极地鞭毛。当在固体培养基上生长时，许多菌株都有丰富的鞭毛。两个类群与前面描述的物种相似，并被指定为B。溶藻藻素A和B。纳特里根。其余四组被指定为B组。Campbellii、海参B.Nereida和B.Nereida。佩拉吉亚。另外一组具有贝氏杆菌属特性的表型相似菌株没有包括在数值分析中。这些菌株很容易从该属的物种中分离出来，并被命名为B。副溶血性。在剩下的组中，有一组被鉴定为费氏发光杆菌。另一组(B-2)，其DNA中GC含量约为41%，不能归入现有属。
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 genusBeneckea. 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 designatedB. alginolyticaandB. natriegens. The remaining four groups were designatedB. campbellii, B. neptuna, B. nereida, andB. pelagia. An additional group of phenotypically similar strains having the properties of the genusBeneckeawas not included in the numerical analysis. These strains were readily separable from species of this genus and were designatedB. parahaemolytica. Of the remaining groups, one was identified asPhotobacterium fischeri. The other group (B-2) which had about 41 moles% GC content in its DNA could not be placed into existing genera.
