Nah, don't feel bad about it. I'm just glad I learnt how to do 16s 
sequencing. Now I'm going to look for new bacteria, I just need to find 
some place where other people haven't been looking before.

Btw, I'm still working with the Ganges bacteria (Paenibacillus alvei). 
It seem to have a plasmid of less than 30kb, so I'm going to see if I 
can establish it in some other bacteria and see if some of the phenotype 
from the Paenibacillus is transferred to the new one, for instance 
antibiotics production. I need some practical work to do inbetween 
reading to exam :)
