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 :) Trond Erik > > Bacillus will only sporulate under adverse conditions.
