2. Optimum plot size of planting and bio-agroeconomic revenues from arugula-carrot intercropping systems in a semi-arid region
Abstract The production of vegetable crops has been characterized as a highly intensive activity in the use of soil, water, inputs and labor in semi-arid regions, being practiced mostly by small family farmers as a way of subsistence, or in the small-scale commercialization of surplus production. Among the agricultural practices that have been successfully u

3. SELEÇÃO DE ESPÉCIES DO GÊNERO Penicillium PRODUTORAS DE LIPASE LIGADA AO MICÉLIO PARA APLICAÇÃO EM HIDRÓLISE DE ÓLEOS VEGETAIS
Ten species of Penicillium genus isolated from different habitats were evaluated as mycelium bound lipase producers to be used in the hydrolysis of vegetable oils. Using olive oil as an inducer three species (P. italicum AT4421, P. janthinellum CCT3162 and P. purpurogenum AT2008) were able to produce lipases having high mycelium bound activities (>150 U g-1)

6. Occurrence of aflatoxin B1 in natural products
The media claims for the consumption of natural resource-based food have gradually increased in both developing and developed countries. The interest in the safety of these products is partially due to the possible presence of toxigenic fungi acting as mycotoxin producers, such as aflatoxins produced during the secondary metabolism of Aspergillus flavus, A.

7. Aspectos bioecológicos do coró-das-hortaliças Aegopsis bolboceridus (Thomson) (Coleoptera: Melolonthidae) no cerrado do Brasil Central.
ABSTRACT: Insects commonly well-known as white grubs are the larval phase of beetles that belong to the Melolonthidae (Coleoptera). This family contains an expressive number of insect species that have different bioecological functions in the agroecosystems in the adult and immature phases. In four of five trophic levels, they are primary and secondary consu

8. Monitoring of potassium in a culture of irrigated bell pepper in semiarid region / Monitoramento do potássio em um cultivo de pimentão irrigado em região semiárida / Monitoramento do potássio em um cultivo de pimentão irrigado em região semiárida / Monitoramento do potássio em um cultivo de pimentão irrigado em região semiárida / Monitoring of potassium in a culture of irrigated bell pepper in semiarid region / Monitoring of potassium in a culture of irrigated bell pepper in semiarid region
The bell pepper is of high importance within the vegetable crops, thus becoming an alternative source of income for small producers and family farms. Potassium is the nutrient most absorbed by bell pepper and diffusion the main transport mechanism to the roots, although the mass flow can have significant contribution in the process under high potassium conce

10. Balanço de 15N em sistemas de produção de milho para adoção do plantio direto no Oeste baiano / 15N balance in maize production systems for no-till in the west State of Bahia
In Cerrado of the west of Bahia state the climate difficulties the formation of vegetable residue for no-tillage. Intercropping cultures is an alternative for climate limitation, for producing biomass to the system. Cotton producers from this region use maize culture for rotation and, in some cases, for formation of straw, with fertilization done exclusively

11. Avaliação termoanalítica da eficiência de antioxidantes na estabilidade oxidativa do biodiesel de mamona
The biodiesel is defined as the mono-alkyl ester derived from long-chain fatty acids, from renewable sources such as vegetable oils or animal fat, whose use is associated with the replacement of fossil fuels in diesel engine cycle. The biodiesel is susceptible to oxidation when exposed to air and this process of oxidation affects the quality of fuel, mainly

12. Produção de gorduras alimenticias zero trans utilizando oleo de palma, estearina de palma e oleo de soja totalmente hidrogenado. / Zero trans food fat production using palm oil, palm stearin and fully hydrogenated soybean oil.
The interest in zero trans fat acids to be utilized in industrialized products has been intensively increased in the last decade. Many of these fats are obtained by the combination of processes, such as interesterification, fully hydrogenation or fractionation. The producers big challenge is to maintain the functional characteristics of the lipid fraction, t
