Here is the fungus I am trying to isolate!

With the help of another intern (Amanda) this week I was able to actually find and identify the fungal endophyte growing in my grass. Neotyphodium is the genes of the endophytic fungi i am finding in the festuca grass samples I am testing on. Now the hard part is to isolate them. In some further research some scientist are using antibiotic enriched media to prevent bacterial growth but not effect fungal growth. Some antibiotics have no effect on a fungus because fungi lack the proper chemical receptors for the antibiotics to target - much like viruses. This may be the next step in finding a media to grow what I want. In the mean time here are some of the pictures of endophytes I took this week. If you look at last weeks post the blue lines are fungus growing between the plant cells and they are very prevalent in these pictures as well.

  1. I thought the reason why most antibiotics do not work on fungi is because most of the components inside a antibiotic are extracted from fungi. For example, penicillin was created through this process so that is why it is effective with killing bacteria but does little to kill other fungi. So you are right, finding a petri dish infused with antibiotic may help kill the bacteria that are getting in the way of you viewing your fungi.
