Exploring cyanobacterial diversity in Antarctica Blog

There are many small ponds and lakes at Cape Evans, similar to Cape Royds . After a quick survey of the ponds, we concentrated on five ponds for sampling. We sampled for morphological, DNA- and RNA-based analysis of the cyanobacterial diversity, as well as nutrient analysis of the water.

 

In one pond we found a pink coloured layer at the bottom of the mats, which is due to the presence of purple bacteria that  are anoxygenic phototrophs.
