Thermal oxidation of methyl oleate was studied over a range of temperatures from 50 C to 150 C for periods of time up to 30 min. Degradation was quantitatively followed by gas liquid chromatography (GLC) and liquid scintillation counting of the products of methyl oleate-U-14C heated under a stream of...

The purpose of this study was to examine the culture
supernatants of various strains of Clostridium botulinum
for characteristic extracellular enzymes which can facilitate
their rapid identification.
A convenient, efficient, water-cooled flat gel electrophoretic
unit was utilized to concentrate and purify the
total proteins and extracellular enzymes present in the...
The purpose of this study was to compare and test the efficiency of the leading kinds of media being used for the isolation and identification
of Clostridium botulinum type E strains, and to develop a
more reliable method and media for the differentiation of this organism
based on the "pearly...
Abundant conidial and sclerotial production occurs on iris
plants infected with Botrytis convoluta Whetzel and Drayton during
the cool moist months of the year. Experiments were designed to
study the survival and inoculum potential of conidia and sclerotia.
Basic nutritional requirements of the fungus in culture were also
studied.
Results...
