Re: What are the effects of ultra-violet light on bacteria growth?

Ultra violet light is actually harmful to many bacteria as it disrupts 
their cell walls.  Just as UV-rays can be harmful to you when you spend 
too much time on the beach.

UV-light can be used in low doses to cause mutation in bacterial cells, 
in higher doses it is lethal.

In short, UV-light will disrupt cell growth and if in a high enough 
exposure will kill the cells.
