Selection of phage insensitive lactic streptococcal strains for use in cheddar cheese manufacture

Creator:: Daniell, Suzanne D.
Abstract:: A survey was conducted of six North American cheese plants to determine levels of bacteriophages present. Fifty-nine lactic streptococcal host bacterial strains were utilized in the survey. Phage levels were generally lower in plants employing modern manufacturing techniques than in plants employing traditional manufacturing techniques; this difference was attributed to...

Evaluation of effectiveness of Rhizobium trifolii strains for Trifolium subterraneum L. (subterranean clover) in southwestern Oregon soils

Creator:: Kibbey, Heather Jean
Abstract:: Twelve high effective Rhizobium trifolii strains were evaluated at four locations in southwest Oregon for the ability to effectively nodulate Mount Barker subterranean clover. All twelve strains possessed antibiotic resistance markers to facilitate identification of strains when extracted from nodules. No significant differences in plant dry weight means could be...

The effects of commercial rhizobium inoculants on the establishment of Trifolium subterraneum in southwest Oregon soils

Creator:: Jenkins, Michael B.
Abstract:: Commercial inoculant products for subclover that are marketed in the Pacific Northwest were evaluated in field trials (supplemented by appropriate laboratory analysis) at four sites in southwest Oregon. The materials tested were Nitragin (Milwaukee, WI) and Northrup-King (Minneapolis, MN) peat-based inocula, and Celpril (Manteca, CA) inoculated, lime-pelleted subclover seed. Duplicate...

Tracing septic system effluent movement through saturated hillslope soils

Creator:: McCoy, Edward L.
Abstract:: Three isolates of Escherichia coli were labeled by their resistance to sodium azide and, separately, to novobiocin, nalidix acid, and tetracycline. The strains exhibited a high degree of persistence in the soil environment and were recoverable on strain specific media at levels within the 95% confidence interval of the numbers...

Partial characterization of six established salmonid cell lines

Creator:: Philippon-Fried, Marie
Abstract:: Six salmonid cell lines previously established in this laboratory, CHSE 114 and CHSE 214 (chinook salmon), CSE 119 (coho salmon), SSE 5 (sockeye salmon), STE 137 (steelhead trout) and RTH 149 (rainbow trout), were partially characterized. Mycoplasmas were not detected in any of the cell lines. All cell lines exhibited...

Acid-producing activitiy of lyophilized lactic streptococcal cheese starter concentrates

Creator:: Yang, Niann-luu
Abstract:: Freeze-dried concentrates (DRICONS) of lactic streptococcal starter bacteria (single and mixed strains) were prepared in different lyophilization media and stored under vacuum and several gases. DRICONS were tested for survival and acid-producing activity after storage for up to a year by rehydration with water to the original pre-lyophilization volume. Acid...

Partial purification and characterization of hemolysin from a psychrotrophic Kanagawa positive marine vibrio

Creator:: Huggins, Susan Peters
Abstract:: Psychrotrophic Kanagawa positive marine vibrios distinct from V. parahaemolyticus were isolated from shellfish collected in Yaquina Bay, Oregon. Sample enrichment in GSTB was followed by culture isolation on TCBS agar. The 235 vibrio isolates obtained were screened for gram reaction and morphology, Kanagawa reaction on Wagatsuma agar and their response...
