I,m trying to produce auxotrophic mutants of A.fumigatus and A.niger.
The method that I intend to use is firstly to harvest spores from each organism
and secondly to expose these spores to UV radiation in 30s bursts upto 10mins in
order to produce a kill curve.  Can anyone offer me any advice on this technique and
comment on any problems that I may encounter and the ways to overcome them?

Thanks in advance,
