Heterotrophic bacteria associated with a feed algae for oyster larvae

Creator:: Johnson, Lynn I.
Abstract:: Aerobic heterotrophic bacteria associated with oyster larvae feed algae Isochrysis galbana, Monochrysis lutheri and Pseudoisochrysis paradoxa were isolated and enumerated. The bacterial numbers ranged from 7.8x10³ to 3.9x10⁶ CFU per ml. The bacteria associated with Pseudoisochrysis sp. were identified and the majority of isolates belonged to genera Leucothrix (51%). Also...

Inhibition of Escherichia coli trimethylamine-N-oxide reductase by food preservatives

Creator:: Kruk, Mark W.
Abstract:: Trimethylamine-N-oxide (TMA-0) reductase activity of resting cells of Escherichia coli was inhibited by tetrasodium ethylenediaminetetraacetate (Na₄EDTA), benzoic acid (BA), and methylparaben (MP). The 50% inhibitory concentrations of Na₄EDTA, BA, and MP were 20.2, 1.2, and 32.4 mM, respectively. BA at pH 6.5 or below most effectively inhibited the TMA-0 reductase....

Dimethyl disulfide produced in sterile fish muscle by Pseudomonas putrefaciens

Creator:: Rhee, Kie Ho
Abstract:: Sterile fish muscle homogenate was prepared from the individually line caught black rockfish (Sebastes melanops) and inoculated with the pure culture of Pseudomonas putrefaciens strain 17. The inoculated homogenate was incubated at 5°C and the growth and production of volatile sulfur compounds determined by a combined gas-liquid chromatography and mass...

Adhesive property of bacteria and its relationship to microbial spoilage of shrimp

Creator:: Smith, John B.
Abstract:: Pacific shrimp (Pandalus jordani) was washed repeatedly and the eluted bacteria were enumerated and identified. Selected isolates were tested for their adhesive properties. Washing reduced the microbial load by 3.84 to 42.04%. The bacteria which most resisted wash-off were Staphylococcus and Pseudomonas spp. The easiest to wash off was Flavobacterium...

Tropical Fruit Aroma: Relevance to Oregon White Wines, the Effect of Winemaking Processes on Fermentation Esters and Volatile Thiol Levels, and the Relationship Between Sensory Perception and Volatile Chemistry

Creator:: Iobbi, Angelica
Abstract:: Aroma is one of the major components that determines the quality of wine and consumer acceptability. Fruitiness is a highly desirable aroma quality in white wines and has been well accepted by consumers across the globe. Tropical fruit aroma has been substantially studied in Sauvignon Blanc wines due to its...

Characterization of factors affecting pectinmethylesterase activity in cucumber fruit

Creator:: Turk, Farzaneh
Abstract:: Pectinmethylesterase (PME) activity in fresh cucumber fruit was determined. The effects of several cationic species, temperature, pH, and acetic acid on the activity of cucumber PME was investigated. The efficacy of blanching, infiltration with CaCl₂ or acetic acid, and fermentation with 0 and 40 mM CaCl₂ on inhibition of cucumber...

Intrinsic and extrinsic quality of West Coast albacore tuna (Thunnus alalunga)

Creator:: Wheeler, Sena C.
Abstract:: The purpose of this study is to identify the intrinsic and extrinsic quality characteristics of West Coast albacore tuna (Thunnus alalunga). Albacore tuna were troll caught off the Oregon coast and transferred to the Oregon State University Seafood laboratory in Astoria, Oregon. Core samples were extracted from six designated body...
