| ABSTRACT The aim of this study was to evaluate the possible protective of C. guianensis oil against MMC and CP, which are direct- and indirect-acting chemical mutagens, using the micronucleus test. Three experiments were performed. First the C. guianensis oil was co-administered to mice at doses of 250, 500 and 1000 mg/kg bw with 4 mg/kg bw MMC or 50 mg/kg bw CP. Second, the mutagenic drug (CP) was administered ip 50 mg/kg bw and after 6 and 12 hours 250 and 500 mg/kg bw of C. guianensis oil were administered. In the last, C. guianensis oil was administrated (250 and 500 mg/kg bw) during five days and after it was administered ip 50 mg/kg bw CP. The results obtained showed that the C. guianensis oil is not cytotoxic neither genotoxic to mouse bone marrow.... |

| When oil spills occur, behavior is the first line of defense for a fish to avoid being contaminated. Here, we determined the avoidance threshold of the European seabass (Dicentrarchus labrax) to the water-soluble fraction (WSF) of oil using a dual flow choice box. Our experiment revealed that a plume of 20%-diluted WSF (total PAH concentration: 8.54 μg L-1) triggered a significant avoidance response that was detected within 7.5 minutes of introducing WSF-contaminated water in the experimental set-up. However, the ecological relevance of seabass capacity to detect and avoid WSF remains to be established. In the short term, such response is indeed liable to reduce sea bass contact time with oil-contaminated water and thus preserve their functional integrity.... |

| El ambiente marino posee una pobre capacidad de respuesta al impacto de los hidrocarburos petrolí-feros, tanto por la baja concentración de nutrientes disponibles (nitrógeno y fósforo), como por la baja frecuencia de aparición de bacterias hidrocarbonoclastas. Teniendo en cuenta la posibilidad que ofrecen las células inmovilizadas de transformar los hidrocarburos del petróleo sin que ocurra dupli-cación celular, en este trabajo se realizó un estudio de la necesidad o no de añadir nutrientes al BIO-IL (producto hidrocarbonoclasta a partir de células inmovilizadas). Se demostró por Cromatografía Gaseosa de Alta Resolución, que no es necesario añadir nutrientes al agua de mar para que ocurra una degradación eficiente de los hidrocarburos del petróleo por... |

| Apparent digestibility coefficients and serum parameters were measured to evaluate the effect of supplementing feed concentrates with rice bran oil in horses. Twelve horses (6 males and 6 females) with a mean age of 18 ± 4 months old and mean live weight of 306 ± 22.6 kg were used. Treatments consisted of increasing rice bran oil concentrate levels of 0, 3.5, 7.0, 10.5, 14.0 and 17.5%, considering a daily intake of 2.25% live weight on a dry matter basis. A dietary effect of supplementation on the apparent digestibility of gross energy (y = 64.55 - 0.58x) was observed (P<0.05). No effect on the other nutrients was observed (P>0.05). Supplementation did not affect serum glucose levels (P>0.05), but cholesterol was affected (P<0.01) based... |

| Background: Different parts of the tree Calophyllum inophyllum L. (nuts, leaves, roots, bark, fruits, nut oil and resin) are used as traditional medicines and cosmetics in most of the Pacific Islands. The oil efficiency as a natural cure and in traditional cosmetics has been largely described throughout the South Pacific, which led us to investigate C. inophyllum's chemical and genetic diversity. A correlative study of the nut resin and leaf DNA from three distinct archipelagos in the South Pacific was carried out in order to identify diversity patterns in C. inophyllum across the South Pacific. Methods: Calophyllum inophyllum plants were sampled from French Polynesia, New Caledonia and Fiji. We extracted tamanu oil (nut oil) resin for chemo-diversity... |

| Abstract The vast Amazon region has considerable territorial peculiarities and plant species diversity, sometimes from the same botanical family, which can exhibit significant differences in physicochemical properties. From this diversity, two species stand out – Amazonas tucumã (Astrocaryum aculeatum Meyer) and Pará tucumã (Astrocaryum vulgare Mart.). The research focus is to analyze, comparatively, these oleaginous fruits, their similarities, particularities and potentials regarding the oil quality extracted from two tucumã varieties from the states of Amazonas and Pará, obtained using supercritical carbon dioxide, under different extraction parameters. The results demonstrate the biometric particularities of each species, highlighting the Amazon fruit,... |

| Olive is one of the strategic products in Iran, and due to the significant cultivation area of this product, oil companies should be equipped with suitable processing equipment. Unfortunately, despite the high capacity of olive in Iran, oil companies are equipped with imported machines. In this study, the construction and evaluation of the Three-counter device of Iran has been developed. The machine has three oil, water and olive pulp outputs. In order to evaluate the machine, the amount of moisture content and fat extracted from the machine was checked at 2500 and 3500 rpm and 30 and 45% water content. Also, four different samples Manzallina, Fishemi, Kalamata and Oily were used in this experiment. The main components of the machine include an electric... |

| Quality is considered to be mainly related to protein and oil concentration in maize kernel. Great effort has been made through the elevation of oil and protein concentrations; however, studies to enhance the composition quality of oil have been limited. Maize genotypes with special fatty acid composition may confer different end uses and added value. We investigated eight maize inbreds for kernel quality and fatty acid composition. Kernel samples from a two-year experiment were analyzed for oil, protein, moisture and ash, as well as several fatty acids, including oleic, linoleic, and linolenic acids. Results indicated differences among the genotypes for all traits, except for behenic acid. A680 appeared to be a promising parent to elevate oleic acid,... |

| A completely randomized design with six replicates of 30 birds per experimental unit was used to evaluate the effect of five fat sources of diets (soybean oil, poultry fat, acidulated soybean oil soapstock and a mix of soybean oil plus poultry fat and soybean oil plus acidulated soybean oil soapstock) on the performance of male Ross broilers, during the growing period (1-45 days of age). The diets for each phase were isonutritional. Broilers fed on soybean oil showed higher weight gain in comparison to the birds fed on diets containing acidulated soybean oil soapstock (P<0.05), but no differences were observed among the other treatments. The feed intake of birds fed on soybean oil was higher compared to the birds fed on acidulated soybean soapstock diet... |

| Potassium (K) and phosphorus (P) application to sunflower (Helianthus annus L.) reduced cost of production, increased seed oil and protein concentration, yield and net returns on the K and P deficient soils in Northwest Pakistan. Field experiment was conducted at the New Developmental Research Farm of NWFP (North West Frontier Province) Agricultural University Peshawar, Pakistan during summer 2006. The experiment was carried out in a randomized complete block design with split plot arrangements using three replications. Six levels of K (0, 25, 50, 75, 100 and 125 kg ha-1) were kept in main plots while four levels of P (0, 45, 90 and 135 kg ha-1) were kept in sub-plots. Increase in K and P levels enhanced seed oil concentration, on the other hand, increase... |

| The amount of energy required to produce a commodity or to supply a service varies from one production system to another and consequently giving rise to differing levels of environmental efficiency. Moreover, since energy prices have been continuously increasing over time, this energy amount may be a factor that has economic worth. Biomass production has a variety of end-products such as food, energy, and fiber; thus, taking into account the similarity in end-product of different crops (e.g.: sunflower, peanuts, or soybean for oil) it is possible to evaluate which crops require less energy per functional unit, such as starch, oil, and protein. This information can be used in decision-making about policies for food safety or bioenergy. In this study, 23... |

| Abstract The objective of this research was to evaluate the quality parameters and the chromatographic, thermogravimetric, and spectroscopic profile of Patauá oil (Oenocarpus bataua). All analyses were performed according to the Recommended Practices of the American Oil Chemists’ Society (AOCS). The parameters obtained indicate conservation quality standards in accordance with Brazilian legislation. The fatty acid profile shows a predominance of ω-9, ω-6, and ω-3 fatty acids. The thermogravimetric behavior and differential analysis indicated good stability upon gradual temperature increase and the presence of endothermic and exothermic peaks characteristic of thermal and oxidative decomposition at high temperatures only. The spectroscopic profile evidenced... |
