摘要：从位于西班牙东南部的太阳盐场随机挑选了516株盐度在8.8%至40.0%(w/v)之间的中度嗜盐细菌进行了研究。经纯化后，对106株盐酸菌和2株参比菌株进行了细胞学、生理生化、营养和抗生素敏感性测定。利用贾卡德系数(S J)对数据进行数值编码和分析，并通过平均连锁分析获得菌株聚类群。在72.5%的相似性水平上，发现了9个主要物候。给出了每种物候的性质，讨论了它们的分类亲缘关系，并推荐了典型的参考菌株。几乎所有的菌株都与已知含有海洋物种的属有关。大量的菌株可以暂时归入弧菌属，这表明这可能是太阳盐碱地中丰富的中度嗜盐革兰氏阴性杆菌分类群。
Summary: A study was made of 516 randomly selected isolates of moderately halophilic bacteria from solar salterns showing salinities between 8.8 and 40.0% (w/v) total salts, located in S.E. Spain. After purification, many cytological, physiological, biochemical, nutritional and antibiotic sensitivity characters were determined for 106 selected saltern isolates and two reference strains. Data were coded and analysed by numerical techniques using the Jaccard coefficient (S j), and clusters of strains were obtained by average linkage (UPGMA) analysis. Nine major phenons were found at the 72.5% similarity level. The properties of each phenon are given, their taxonomic affinities are discussed, and typical reference strains are suggested. Almost all the strains were related to genera known to contain marine species. A large number of the strains could be tentatively assigned to the genus Vibrio, suggesting that this may be an abundant taxon of moderately halophilic Gram-negative rods in solar salterns.
