I was quite intoxicated when I wrote my first post and in doing so forgot all about it.
Darklight, thanks for your input.
I have only just began discussing this with my potential supervisor this week. As it would be a project for next year, he suggested that I get hold of a plant of interest and develop a callus culture as you suggested and then isolate and develop a sterile hairy root culture.
The equipment that I have available was designed by a Professor in Korea who now mass produces ginseng roots. Quite an amasing feet considering they take 23-26years to reach maturity in the ground, where he has a couple of month turn over, hence why all these new energy drinks can contain it for so cheap. This is also why I am focusing on a root culture system, as the equipment is purposely designed for that. Although there is a degree of flexability there if a shoot culture presents itself.
The first plant that my supervisor suggested off the top of his head was Derris. Despite that it is not the soundest ecologically, it was that he new the roots contained the compound rotenone and that I would get a result out of the experiment. Not to sure if I am that keen on this one though.
Also as you sugessted Darklight, my supervisor has recommended that I find a plant that has been successfully cultured and try and tweek the methods, even to compare any potential yields through comparison of hairy root, suspension, etc.
Obtuse, I was not sure where to place this thread, but you may be right that it should go in the chemistry section, but now I am not sure how to move it.
Heretic, I like your suggestion too. I happen to be doing a small research project next semester, testing the anti-microbial properties of some various Australian natives, of which I will post up my results if I find anything of interest.
Once again, thanks for your interest people, and please keep the suggestions coming. I would like to get a culture going this year so that I will have a sterile product to begin with next year
