摘要

尽管铜是一种必需的微量营养素，但它也是一种潜在的有毒重金属。通过选择实验，我们产生了对铜离子耐受性增强的莱茵衣藻种群，然后从这些种群中衍生出纯细胞系。来自同一种群的菌株（适应和非适应）在生长参数方面存在显著差异。在一系列铜离子浓度下培养菌株显示出生长和光合性能的差异，这可能归因于每次细胞分裂时发生的微进化过程。我们的研究结果证明了环境因素对微生物快速繁殖的影响。

Intrapopulation Diversity of Chlamydomonas reinhardtii Response to Copper Ions: Growth and Photosynthetic Performance Under Stress

Despite being an essential micronutrient, copper is also a potentially toxic heavy metal. Using selection experiments, we produced Chlamydomonas reinhardtii populations with increased tolerance of copper ions and then derived pure cell lines from these populations. Strains derived from the same population (both adapted and nonadapted) significantly differed in terms of growth parameters. Cultivation of the strains in a range of copper ion concentrations revealed differences in growth and photosynthetic performance, which could be attributed to microevolutionary processes occurring with each cell division. Our results demonstrate the effects of environmental factors on rapidly multiplying microorganisms.
