Algal Research Project

For my research project this semester, I wanted to do something regarding algae with a focus on genetics. So, I came up with a toxicity bioassay based on J.I. Nirmal Kumar's study, "Toxicity analysis of pesticides on cyanobacterial species by 16s rDNA molecular characterization."

Once I isolate single colonies of my algal species, Nannochloropsis sp. and Arthrospira platensis, I will do a PCR (polymerase chain reaction) of the 16s RNA gene. Then I will subject the cultures to increasing amount of foliar pesticide, tebuconazole, similar to Kumar's study. However, I will be using a home use formula of the same brand, Kumar used a commercial agriculture formulation. The idea is to continue doing a PCR and record any mutations in the RNA structure; such as insertions, deletions or mismatching of base pairs.

Here are a few photos of the starter cultures.

Glad to be Back

Hi everybody! It feels really good to be back and I hope to hit the ground running, so to speak. I have decided to do my project on the toxicity of pesticides on cyanobacterial species; in this case Nannochloropsis and Arthrospira aka Spirulina. Matt has already ordered the cultures, so hopefully things go smoothly while I try to grow my cyanobacteria. Since it may not work out, I may do a back up project concerning algae. I'm not sure what at this point, so cross your fingers for me! I look forward to seeing you all at orientation Friday. Here's to a great semester! :)
