This investigation was undertaken to determine 1) the effects
of various carbon sources in defined media on pectolytic enzyme production,
2) the effect of the incubation period on pectolytic enzyme
activity, and 3) the development of improved methods for the purification
and characterization of the polygalacturonases (PG) produced
by Fusarium...
The biochemical composition of ten species of estuarine phytoplankton
was determined. Studies were made of their growth in
various culture media and of their relative value as food for oyster
larvae. Nine of the species were isolated from Yaquina Bay, Oregon.
An attempt was made to select species which commonly...
The objectives of this study were to 1) develop a relatively quick staining procedure that would detect incipient decay by color differentiation under fluorescence, 2) quantitatively assess the amount of decay present with the use of an image analyzer, and 3) re/ate loss in strength at various decay levels to...
While water scarcity and energy demand are continuously increasing in the world, alternative sources are needed to meet the requirement of a growing population. Microbial Fuel Cell (MFC) is a sustainable technology that converts organic matter in wastewater into electricity, thus it can be a potential alternative source for water...
The purpose of this study was to isolate and characterize any
segregants of the heterogenotes formed from sexduction by an F'
donor. Following the mating of F' W4520, carrying an F' gal₁⁺
gal₂⁺ factor, with W3350, a gal₁⁻ gal₂⁻ recipient, a number of
recombinant clones were picked and examined for...
This study examines two major issues: (1) to what extent have the
conditions at non-reservation Indian boarding schools, as described by
the Meriam Report of 1928, been in evidence from the beginning?; and
(2) to what extent have these conditions improved since 1928?
The conditions examined are: (1) General Conditions...
The purpose of this annotated bibliography is to guide middle school and high school students into critical thinking about environmental issues. Through keen observation of their bioregion and through an integration of interdisciplinary literature which focuses on Oregon writers, students will be challenged to think, write, and discuss current issues...
Pacific sardines (Sardinops sagax) are an economically and ecologically important forage fish which transfer energy from planktonic primary producers and secondary consumers to upper trophic predators. Previous genetics studies of Pacific sardine suggested a panmictic population with a shallow genetic structure. However, more than one subpopulation within the Central California...
