A morphologically distinct heliobacterium, strain HH, was isolated from Lake El Hamra, a soda lake in the Wadi El Natroun region of northwest Egypt. Strain HH consisted of ring-shaped cells that remained attached after cell division to yield coils of various lengths. Strain HH showed several of the physiological properties of known heliobacteria and grouped in the Heliorestis clade by virtue of its phylogeny and alkaliphily. The closest relative of strain HH was the filamentous alkaliphilic heliobacterium Heliorestis daurensis. However, genomic DNA:DNA hybridization results clearly indicated that strain HH was a distinct species of Heliorestis. Based on its unique phenotypic and genetic properties we describe strain HH here as a new species of the genus Heliorestis, H. convoluta sp. nov.
从埃及西北部纳特龙湖谷地区的一个苏打湖——哈姆拉湖分离出一种形态独特的太阳杆菌，即HH菌株。HH菌株由环形细胞组成，细胞分裂后仍保持附着状态，形成各种长度的螺旋。HH菌株表现出已知太阳杆菌的一些生理特性，根据其系统发育和嗜碱性，它归属于日光杆菌属分支。HH菌株最亲近的亲缘种是丝状嗜碱性太阳杆菌达乌尔日光杆菌。然而，基因组DNA:DNA杂交结果清楚地表明，HH菌株是日光杆菌属的一个独特物种。基于其独特的表型和遗传特性，我们在此将HH菌株描述为日光杆菌属的一个新物种，即卷曲日光杆菌新种。
