The interface between the hypersaline brine and the overlying sea-water (brine-seawater interface) of the Shaban Deep, northern Red Sea was investigated for the presence of microorganisms using the 16S rRNA gene as a molecular marker. Samples of the south and east basin (depth: 1331 m and 1332 m respectively) were selected to ascertain the microbial diversity of this extreme and, so far, unexplored environment. Phylogenetic analysis revealed novel lineages within the Bacteria, the Crenarchaeota and the Euryarchaeota. Novel representatives of the KB1 sequence group (Eder et al., 1999 Arch Microbiol 172: 213-218) were detected indicating a widespread distribution of the corresponding Bacteria in Deep Sea brine pools. Our results contribute to the understanding of the hitherto unknown microbial diversity at the chemical gradient of the Shaban Deep, and suggest the presence of novel Bacteria and Archaea thriving under extreme environmental conditions.
利用16S rRNA基因作为分子标记，对红海北部沙班海渊高盐卤水与上覆海水之间的界面（卤水 - 海水界面）进行了微生物检测。选取了南部和东部盆地的样本（深度分别为1331米和1332米），以确定这个极端且迄今为止未被探索的环境中的微生物多样性。系统发育分析揭示了细菌、泉古菌门和广古菌门内的新谱系。检测到了KB1序列组的新代表（埃德尔等人，1999年，《微生物学档案》172: 213 - 218），这表明相应细菌在深海卤水池塘中广泛分布。我们的研究结果有助于理解沙班海渊化学梯度上迄今未知的微生物多样性，并表明存在能在极端环境条件下繁衍的新型细菌和古菌。
