    Notes: The free living nematode Panagrellus redivivus has shown promise as a live food for marine shrimp and fish. This study evaluated the effect of three media on the fatty acid (FA) profile of nematodes. The media tested were: wheat flour (WF), wheat flour plus yeast (WFY), and wheat flour plus yeast plus fish oil (WFFO).The total lipid content of nematodes grown on WFFO (14.9%) was significantly higher than the lipid content of nematodes grown on WF (2.7%) and WFY (4.4%). The lipid of nematodes grown on WFFO also contained a higher percentage of n-3 highly unsaturated fatty acids (HUFA) (11.2%), especially 20:5(n-3) (7.4%) and 22:6(n-3) (3.3%), than nematodes grown on WF (4.8%) and WFY (5.7%). Nematodes grown on WFFO medium had similar lipids as Artemia, especially desirable n-3 HUFA's.Total daily yield of nematodes was highest on WFY. There was no difference in yields of nematodes on WF and WFFO. This study has shown that the nutritional value of nematodes can be influenced by the media on which they are cultured. With a proper medium, cultured nematodes can provide the inexpensive, consistently nutritious live food that can be considered for larval culture of marine crustaceans and fish.

    Notes: Individually quick frozen lowbush (wild) blueberries (Vaccinium angusrifolium) were canned with 0, 1500, or 3000 ppm calcium from chloride or lactate salts and 0, 0.25, or 0.50% citric acid in water. Physical and pH changes were measured at 0, 6, and 12 mo, and sensory evaluations were made at 3 and 9 mo post-canning. Calcium increased firmness and berry calcium content. Calcium chloride and citric acid reduced pH and increased hue angle and off-flavor; calcium lactate increased drained weight and pH but reduced hue. Response surface methodology predicted changes in calcium lactate-treated berries, but not CaCl2-treated berries. Optimal conditions were 1200–1800 ppm calcium lactate at 3–6 mo storage.

    Optimization of Extraction of Peanut Proteins with Water by Response Surface Methodology (1991)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of food science 56 (1991), S. 0 
    Details
    ISSN: 1750-3841
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition , Process Engineering, Biotechnology, Nutrition Technology
    Notes: Water extraction of peanut proteins was optimized to maximize protein extraction, Y1 and protein concentration in the extract, Y2. A central composite design involving solids-to-water ratio (X1), pH (X2), temperature (X3) and time (X4) was used, and second-order models for Y1 and Y2 were employed to generate response surfaces. The optimum conditions to obtain Y1≥ 85% and Y2≥ 2.5% were X1= 1:8; X2= 8.0; X3= 50 °C; X4= 30 min. Estimates of Y1 and Y2 at the optimum were 85.29% and 2.7%, respectively. Experimental verification gave values of Y1= 84.39%± 0.78 and Y2= 2.80%± 0.02. Y1 and Y2 were further maximized, as measured by absorbance of solution following centrifugation of the extract, when papain (0.05% g/g peanuts) was added and extraction was carried out at the optimum conditions.

    Effect of aluminium on lipid peroxidation, superoxide dismutase, catalase, and peroxidase activities in root tips of soybean (Glycine max) (1991)
    Oxford, UK : Blackwell Publishing Ltd
    Physiologia plantarum 83 (1991), S. 0

    Notes: Inhibition of root elongation and modification of membrane properties are sensitive responses of plants to aluminium. The present paper reports on the effect of AI on lipid peroxidation and activities of enzymes related to production of activated oxygen species. Soybean seedlings (Glycine max L. cv. Sito) were precultured in solution culture for 3–5 days and then treated for 1–72 h with Al (AICI3) concentrations ranging from 10 to 75 μM at a constant pH of 4.1. In response to Al supply, lipid peroxidation in the root tips (〈 2 cm) was enhanced only after longer durations of treatment. Aluminium-dependent increase in lipid peroxidation was intensified by Fe2+ (FeSO4). A close relationship existed between lipid peroxidation and inhibition of root-elongation rate induced by Al and/or Fe toxicity and/or Ca deficiency. Besides enhancement of lipid peroxidation in the crude extracts of root tips due to Al, the activities of superoxide dismutase (EC 1.15.1.1) and peroxidase (EC 1.11.1.7) increased, whereas catalase (EC 1.11.1.6) activity decreased. This indicates a greater generation of oxygen free radicals and related tissue damage. The results suggest that lipid peroxidation is part of the overall expression of Al toxicity in roots and that enhanced lipid peroxidation by oxygen free radicals is a consequence of primary effects of Al on membrane structure.

    Notes: Fifteen strains, assigned to four pathogenic races of Fusarium oxysporum f.sp. vasinfectum on the basis of host range, were characterized by means of vegetative compatibility, restriction fragment length polymorphisms (RFLPs) and pigmentation on aesculin-containing medium. Isolates were divided into two major vegetative compatibility groups (VCGs) comprising Races 1 and 2 (VI) and Race 3 (V2). The two VCGs were represented by a single RFLP pattern. An additional RFLP pattern was observed for a single Race 4 isolate. Isolates received as belonging to Races 2, 3 and 4 blackened aesculin agar, while designated and presumed Race 1 isolates gave a negative reaction.

    Selection in Early Generations of Dried Peas, Pisum sativum L. III. Plot Size and Plot Type (1990)
    Oxford, UK : Blackwell Publishing Ltd
    Plant breeding 105 (1990), S. 0

    Topics: Agriculture, Forestry, Horticulture, Fishery, Domestic Science, Nutrition
    Notes: Investigations were carried out to study the effect of different plot sizes and plot types on the performance of peas and to determine plot size and plot type combinations suitable for the reliable evaluation of varietal yield performance realized in commercial stands of pea crops. Four pea varieties were tested in 1981 and 1982 in combinations of plot sizes ranging from 0.25 m2 to 19.50 in2 with plot types either unbordered, bordered with faba beans, surrounded with perforated plastic foil or only central sections of plots harvested (net plots).With decreasing plot size the performance mean as well as the error variance of grain yield and thousand grain weight increased disproportionately. Thus, changes in grain yield were much higher than those for thousand grain weight. The four varieties tested reacted differently to changing plot sizes and as a result, highly significant variety × plot size interactions were found. Although overestimation of grain yield in small plots could be strongly reduced by bordering the plots with faba beans or surrounding them with plastic foil, their suitibility for yield testing was limited by highly significant variety × plot type interactions. Compared to the largest net plot (15 m2) reliable results were still obtained with plot sizes larger than 6.5 m2, no matter whether edge effects were eliminated or not. If only a small quantity of seed is available, plots may be reduced even to 1.00 m2, if surrounded by plastic foil.The results presented in peas were compared to those in other crops and discussed concerning their relevance for variety testing as well as for selection of grain yield in early generations.

    Diagenesis and formation water chemistry of Triassic reservoir sandstones from southern Tunisia (1994)
    Oxford, UK : Blackwell Publishing Ltd
    Sedimentology 41 (1994), S. 0 
    Details
    ISSN: 1365-3091

    Topics: Geosciences
    Notes: The fluvial Triassic reservoir subarkoses and arkoses (2409·5–2519·45 m) of the El Borma oilfield, southern Tunisia, were subjected to cementation by haematite, anatase, infiltrated clays, kaolinite and K-feldspar at shallow burial depths from meteoric waters. Subsequently, basinal brines controlled the diagenetic evolution of the sandstones and resulted initially in the precipitation of quartz overgrowths, magnesian siderite, minor ferroan magnesite and anhydrite. The enrichment of siderite in 12C isotope (δ13CPDB= - 14·5 to - 9‰) results from derivation of carbon from the thermal decarboxylation of organic matter. During further burial, the precipitation of dickite and pervasive transformation of kaolinite into dickite occurred, followed by the formation of microcrystalline K-feldspar and quartz, chlorite and illite, prior to the emplacement of oil. Present day formation waters are Na-Ca-Cl brines evolved by the evaporation of seawater and water/mineral interaction and are in equilibrium with the deep burial (≤ 3·1 km) minerals. These waters are suggested to be derived from the underlying Silurian and Devonian dolomitic mudstones.
