A comparative study of the lethal effect of metabisulphite on the viability of three bacterial species in bone meal and gelatin.
An investigation into the effect of sodium metabisulphite on the viability of three bacterial species, Salmonella typhimurium 59143, Escherichia coli ES-1 and Pseudomonas aeruginosa 8602, in bone meal and gelatin has been reported in this paper. Methods used in detecting the viability of the bacteria after exposure to metabisulphite-treated bone meal and gelatin have been presented. Results have shown that the bacterial species were all susceptible to metabisulphite in both rendered by-products but in all cases, the micro-organisms were far more susceptible in metabisulphite-treated gelatin than in metabisulphite-treated bone meal. Reasons for the difference in susceptibility were also adduced.
