Interesting topic that never comes up in filtration discussions. Looked up several research papers available on the internet and it looks like light indeed does have a negative effect on the bacteria and conversion decreases. The effect varies with wavelength and light intensity on the media. Looks like if you want to maximize conversion keep the media in a dark container. If your media is exposed to light just add extra media to compensate for any reduction.
