Langheld (1) found that sodium hypochlorite reacts with a-amino acids to form chloramino acids, which more or less readily break down to aldehydes or ketones, ammonia, carbonic acid, and sodium chloride. Milroy (2) pointed out that in the case of aromatic or heterocyclic amino acids, such as tyrosine or tryptophane, partial chlorination of the ring takes place in addition to oxidation. Hypochlo...

The aim of this study was evaluation an organic germicide (Aquagerm) histological affects on Rainbow trout (Oncorhynchus mykiss) vital tissues. This new disinfectant is an aquatic antiseptic and mixed-oxidant disinfectant which is produced for the first time in Iran. This new product mechanism is based on oxidant properties of pro-sulphate which attack crucial structures of pathogens. In this s...

The killing of bacterial cells by chemical agents may be considered as the resultant of a reaction between two systems, the cells and their suspending medium and the germicide and its solvent. The method for testing sanitizing agents proposed by Weber and Black (1948) allows evaluation, on the basis of the two systems, of factors such as ions present in the suspending or diluting medium, organi...

Theoretical analysis of the mechanism of action of chemical aerial disinfectants reveals that the rapid killing action which is obtained cannot be accounted for by a collision process between germicidal aerosol particles and the air-borne bacteria. However, a mechanism involving condensation of germicide molecules in the vapor state on to the bacteria-containing droplets results in a theoretica...

The calcium leucovorin assay was improved by adding THORAL germicide which resuspended the cells so that an accurate turbidity reading could be obtained.
