The purpose of this research was to determine whether the transducing phage Pl picks up original bacterial chromosome segments and whether these segments are always the same size. The plan of approach was to grow the donor bacteria Escherichia coli C600 gal⁺ (galactose) in minimal media containing the heavy isotopes...
Submicron particulate (mean size of 0.52 microns) was filtered
from air at substantially atmospheric temperature and pressure by
passing air up through a bed of fluidized glass shot in a two inch column.
Removal efficiency, defined as the percentage removal of
particulate from the air stream, was essentially constant during...
The role of beta-carotene degradations in the development of
off-flavors in milk and milk products has not been established. The
purpose of this investigation was to study the oxidation of beta-carotene
and to identify volatile compounds arising from autoxidizing
beta-carotene.
Pure cyrstalline beta-carotene, mixed with Celite to accelerate
oxidation, was...
