Synthesis of total RNA, DNA, and protein was followed in a
haploid yeast auxotroph during starvation for required amino acids
and uracil, and during shift-up and shift-down conditions.
During amino acid starvation, synthesis of macromolecular
constituents was not immediately affected, reflecting the presence
of large intracellular amino acid pools. Under...
Studies were carried out to elucidate the mechanism of enzymatic
control of methionine biosynthesis in Saccharomyces cerevisiae.
Enzymatic studies demonstrated that, in addition to the methionine
activating enzyme, the S-adenosylmethionine:homocysteine
transmethylase enzyme was induced during cultivation in the presence
of excess methionine. A similar, though reduced effect was
observed when...
The ability of cholestanol to support growth of yeast sterol
auxotrophs has been examined. Growth on this stanol was precluded
unless minute quantities of ergosterol were available, a phenomenon
designated sparking. The low levels of ergosterol were
insufficient to support growth alone. The data indicate that
cholestanol is fulfilling a...
Fish ball is an extruded surimi-based product that is popular among Asian communities. In the manufacturing of fish ball, optimum floatation is extremely important for maximal production. Factors affecting floatation of fish ball in water were investigated. The density of threadfin bream surimi paste significantly decreased (P<O.05) as moisture content...
There are presently two successful methods used to refine fish muscle proteins: surimi and fish protein isolate (FPI). Both surimi and FPI have the ability to form an elastic gel upon comminution and heating. However, their gelation behaviors are different as they are refined in a biochemically opposite way based...

Concern over the low enrollment in homemaking classes prompted this study of the homemaking program in secondary schools in Bend, Oregon. Two questionnaires were constructed to obtain the opinions and beliefs of ninth, tenth, and eleventh-grade girls in Bend, Oregon, and their parents about the following: 1. What factors influence...
