Abstract

Preliminary microbiological investigation of the Barguzin Valley terrestrial hydrotherms did not elucidate the composition of the community of sulfate-reducing prokaryotes (SRP) responsible for high sulfide concentrations in the Kuchiger and Umkhei springs. Measurement of sulfate reduction rate (SRR) with labeled sulfate in the samples collected together with those for determination of community composition by 16S rRNA gene profiling revealed that, while not numerous, the SRP consisting of Desulfobacterota and Thermodesulfovibrio was responsible for a highly active process. SRR in the sediments of the Umkhei and Kuchiger springs was up to 12.7 ± 0.2 and 2.05 ± 0.08 mg S dm–3 day–1, respectively.

低丰度硫酸化细菌在巴尔古津河谷陆地水圈中进行密集的硫酸盐还原作用
摘要--对巴尔古津河谷陆地水圈进行的初步微生物学调查并未阐明造成库奇格尔泉和乌姆黑泉硫化物浓度过高的硫酸盐还原原核生物群落(SRP)的组成。用标记的硫酸盐测量所采集样本中的硫酸盐还原率(SRR),以及通过 16S rRNA 基因分析确定群落组成的样本,结果表明,虽然数量不多,但由脱硫杆菌(Desulfobacterota)和热脱硫弧菌(Thermodesulfovibrio)组成的硫酸盐还原原生生物群落(SRP)负责一个高度活跃的过程。Umkhei 泉和 Kuchiger 泉沉积物中的 SRR 分别高达 12.7 ± 0.2 和 2.05 ± 0.08 毫克 S dm-3 天-1。
