摘要

蓝藻被认为是最早在温泉中定居的微生物之一,它们为进一步的生物建立形成了有利的环境。然而,确切的先驱物种以及它们开始参与生物矿化过程的时间仍然未知。本研究的目的是双重的,即识别温泉(即希腊Aedipsos地区)中的先驱蓝藻,并记录它们的早期生物矿化过程。原位实验方法包括在几个位置设置无菌玻璃和/或有机玻璃载玻片,以促进蓝藻的定植,并在48-202小时后取出载玻片进行研究。聚球菌目(37%)和振荡球菌目(33%)是优势目,其次是藻球菌目(15%)和螺旋藻目(11%);而Chroococcidiopsidales(4%)仅在少数地点发现。在殖民化的早期阶段,虽然在成熟阶段存在,但未观察到该目。43种蓝藻被确定为先驱微生物,其中最常见的是枯草螺旋藻。最常见的先驱是多细胞丝状蓝藻,即具有较大表面积的生物体,能够形成大量的细胞外聚合物质。其中,蓝藻属的嗜热菌属是典型的热球藻属、热双球菌属、热嗜瘦菌属、枯草葡萄球菌属和热共菌属,以及典型的石灰石底物属,如嗜石双球菌属和薄层瘦菌属。温度似乎影响生物多样性。此外,发现先驱者从第一次出现起就对生物矿化过程做出了贡献。在研究的样品中,确定了三种生物矿化过程,即(i)蓝藻鞘的钙化,(ii)碳酸盐晶体在细胞外聚合物物质和细丝形成的晶体保留晶格上的捕获,以及(iii)碳酸盐晶体在丝状蓝藻周围的捕获和限制。

Pioneer species of Cyanobacteria in hot springs and their role to travertine formation: The case of Aedipsos hot springs, Euboea (Evia), Greece

Cyanobacteria are considered to be among the first microorganisms to settle in hot springs where they form a favourable environment for further biological establishment. Nevertheless, the exact pioneer species and how early they start participating in the biomineralisation processes remain unknown. The aim of the present study was twofold, that is, to identify the pioneer Cyanobacteria in hot springs (i.e. Aedipsos area, Greece) and to record their early biomineralisation processes. The in situ experimental approach included the setup of sterile glass and/or plexiglass slides in several locations to facilitate colonisation by Cyanobacteria, and removal of slides for study after 48–202 h. Synechococcales (37%) and Oscillatoriales (33%) were the dominant orders, followed by Chroococcales (15%) and Spirulinales (11%); whereas Chroococcidiopsidales (4%) was found only in a few sites. The order Nostocales was not observed at the early stages of colonisation although it was present in mature stages. Forty-three species of Cyanobacteria were identified as pioneer microorganisms, with Spirulina subtilissima being the most frequently found. The most common pioneers were multicellular filamentous Cyanobacteria, that is, organisms with a large surface area able to form significant amounts of extracellular polymeric substances. Among the pioneers, thermophilic species of Cyanobacteria were typical such as Chroococcidiopsis thermalis, Chroococcus thermalis, Leptolyngbya thermalis, S. subtilissima and Symploca thermalis, as well as typical limestone substrate species such as Chroococcus lithophilus and Leptolyngbya laminosa. Temperature seems to affect biodiversity. Also, pioneers were found to contribute to the biomineralisation processes from their first appearance. In the studied samples, three biomineralisation processes were identified, that is, (i) calcification of cyanobacterial sheaths, (ii) trapping of carbonate crystals on a crystal retention lattice formed by extracellular polymeric substances and filaments and (iii) trapping and confinement of carbonate crystals around filamentous Cyanobacteria.
