The results of several experiments suggest that t,he first step in green plant photosynt,hesis is a cooperative act carried out by a few hundred chlorophyll molecules. By using very short flashes of light, spaced far apart so as not to interfere with each other, Emerson and Arnold (1) found that the maximum number of carbon dioxide molecules reduced per flash was some 2500 times less 6han the n...
Microbiological tests were carried out to evaluate a new chlorine dioxide sterilant: Tristel OneShot. Preliminary in vitro suspension tests showed that solutions containing around 140 ppm chlorine dioxide achieved a reduction factor exceeding 10(6) of Staphylococcus aureus in 1min and of Bacillus subtilis spores in 2.5 min in the presence of 3g/L bovine albumin. Subsequent tests evaluated the e...
