Indoor exposure to the spores and mycelial fragments of fungi that grow on damp building materials can result in increased non-atopic asthma and upper respiratory disease. Test the effects of ultraviolet (uv) exposure on bacterial growth. To determine the inhibitory effects of different concentrations of lauric acid on the c difficile strain r20291, the percentage of growth at each concentration was calculated using the following equation: inhibition (%) = [1 - (od 600 of growth with lauric acid/od 600 of growth in broth only) × 100.

Effects of ultra-violet radiation upon but had a slightly inhibitory effect in heavy doses in non- instances by a comparatively short exposure to ultra-violet. Effects of uv-b exposure on plant morphology and biomass results showed marked difference in the morphology and growth of uv-b irradiated plants as compared to non-irradiated plants of l esculentum. Quick uv sensitivity tests were done by streaking lb agar plates with samples of liquid cultures and exposure to uv light from a 15 w germicidal lamp a gradient of uv doses was achieved by uncovering successive sections of the bacterial streaks.
