摘要

世界上有几个地方的自然辐射水平异常高，例如伊朗拉姆萨尔和阿贝加尔-马哈拉特的一些地区。这些地方的生物多样性还没有得到充分的开发。本研究对6个天然辐射较高的地热温泉中分离的菌株进行了研究。226Ra的最高浓度为13000 Bq。土壤中kg-1和130 Bq。L-1分别溶于水中。形态学和分子分析表明，该菌株不属于任何现有的分类单元。因此，它们被描述为科学上的新分类群。根据我们的研究结果，两个早期描述的物种被转移到新建立的属中。

New simple trichal cyanobacterial taxa isolated from radioactive thermal springs

There are several places in the world where the level of natural radiation is unusually high, such as some regions of Ramsar and Abegarm-e-Mahallat in Iran. Such places are still insufficiently explored in terms of their biodiversity. In this study, strains isolated from six geothermal springs with elevated natural radiation were investigated. The highest concentration of 226Ra were 13,000 Bq.kg-1 in the soil and 130 Bq.l-1 in water respectively. The morphological and molecular analyses revealed, that the strains are not classifiable to any existing taxon. Therefore, they are described as new taxa for science. Based on results of our study, two earlier described species are transferred into newly established genus.
