Numerous investigations have been made on the contribution of
butter cultures to the flavor of cultured cream butter, but production
of uniform cultured cream butter has not been possible in industry.
Therefore, it was desirable to investigate in detail the qualitative
and quantitative chemistry of the flavor of high quality...
An all-glass gas chromatograph was developed for the analysis
of corrosive metal halides. Included in the apparatus is a new liquid
sampling system designed for fast repetitive sampling of corrosive
liquids in an inert atmosphere. A flame photometer detector was developed
to permit the detection of corrosive solutes in the...
This study was a comparison of the prevalence of infectious
gastrointestinal disease and the quality of construction of individual,
surface source water systems in Lincoln County, Oregon.
Two measurement instruments were developed for this study. An
objective instrument was developed to determine if the water systems
observed in the study...
From a population of cells of Pseudomonas aeruginosa sensitive 33 parts per million (ppm) and 0.1 mg per ml of quaternary
ammonium (QAC) and chloramphenicol respectively, pure strains
resistant to 750 ppm and 50 mg per ml of these antibiotics were isolated.
Lipids from the sensitive and resistant cells grown...
The growth of bdellovibrios at the expense of the host organism involves the catabolism of host cell macromolecular components and the subsequent anabolistic incorporation into bdellovibrio progeny. Extracellular enzymes specific for the various substrates provided by the host cell are present. In this study the extracellular RNase of Bdellovibrio bacteriovorus...
