The concentration of seventeen elements in two species of fungus
which cause wheat bunt disease, Tilletia caries (DC.)Tul. (TS) and
Tilletia controversa Kiihn (DS), were determined by instrumental neutron
activation analysis in 37 TS spore samples, and 31 DS spore samples.
Aluminum was chosen as a soil contamination...
2,5-dihydroxyacetanilide epoxidase from Streptomyces LL-C10037 (DHAE I)
catalyzes the epoxidation of hydroquinone 4, to form epoxyquinone 7. DHAE I has been
purified to homogeneity, with an overall purification factor greater than 23,000. N-terminal
and internal amino acid sequences have been obtained from the purified enzyme so
that the epoxidase gene...
A variety of laser spectroscopic methods are employed in this
thesis research for studies of CF₃NO, an interesting model
photodissociative system, and for investigation of low energy rotations
and vibrations of small molecules and low molecular weight clusters in
free jet expansions.
Nonradiative energy decay for electronically excited CF₃NO is...
The study of diffusion coefficients of n-alkanes and other organic compounds in silicones is undertaken by gas-liquid chromatography. About 0. 3% of stationary phase is coated on glass bead support so that the only significant source of peak spreading is due to slow liquid phase mass transfer. Diffusion coefficients are...
The rate of the C¹⁴0₂ release from glucose, specifically labeled
with C¹⁴ at 1, 2, 3+4, and positions, was used to study the relative
participation of pathways of glucose catabolism in red beet slices.
Evidence was obtained which indicated that in mature red beets glucose
was catabolized mainly via glycolysis-tricarboxylic...
The loss of all deuterium labels from previous feedings of [2-²H]-,
[3,3-²H₂]-, and [2,3,3-²H₃]arginines had indicated the possible intermediacy
of β-hydroxy- and β-ketoarginine (30 and 31, respectively) in the
biosynthesis of the streptolidine portion of streptothricin F (la).
In order to confirm or refute this evidence, D,L-[2,3,3,5,5-²H₅]-
arginine (32) was...
