模拟月壤对蓝细菌生长特性的影响

Effects of Simulated Lunar Soil on Cyanobacteria Growth Characters

阐明地球生物在月球环境中的适应性是未来月球探索和基地构建所面临的重要课题,为此以蓝细菌为实验材料,对其在模拟月壤cas-1中的生长状态进行了研究,从生长速率、细胞形态、细胞色素含量等方面表征了月壤对蓝细菌适应性的影响。实验结果表明,四种实验蓝细菌的生长能够适应模拟月壤的影响,其生长速率在模拟月壤处理中保持与常规培养基相似的生长曲线;模拟月壤颗粒上附着生长的菌体形态与对照相比无明显变化;模拟月壤处理后的菌体内色素含量与对照条件下培养的结果无显著差异。该结果对于未来开发月壤资源和构建月球基地受控生态生保系统具有重要意义。

To clarify the biological adaptation of life on earth to the lunar environment is an important aspect of the lunar exploration and base construction in the future. Cyanobacteria was selected as the test material. Its growth in the cas-1 simulated lunar soil was studied and effects of lunar soil on its biological adaptability were observed including the growth rate, cell morphology, and cell pig- ment content etc. The results showed that these four types of cyanobacteria could all adapt to cas- 1 soil and maintained consistent growth curve with the control. There was no significant difference in morphology or pigment content as compared with the control. The result is of great significance for the lunar soil exploitation and construction of Controlled Ecological Life Support System for lunar base in the future.
