The primary purpose of this investigation was to characterize
the lipids of the spores and vegetative cells of Cl. botulinum. A
second purpose was to explore the possibility that lipids might serve
as a means of differentiating the chiefly proteolytic Cl. botulinum
type B from the nonproteolytic Cl. botulinum types...
The purpose of this study was to develop means to facilitate
the detection of staphylococcal enterotoxin and to elucidate factors
that influence enterotoxin formation. It was found that semipurification
flat-gel electrophoresis in a water-cooled apparatus
was more efficient than CM-cellulose and Sephadex column chromatography
currently used to separate toxin from...
