13. Distribution of prokaryotic organisms in a tropical estuary influenced by sugar cane agriculture in northeast Brazil
In a joint Brazilian-German case study, distribution patterns of microorganisms were compared with environmental variables in the tropical coastal Manguaba lagoon in northeast Brazil, which is situated downstream of several sugar cane processing plants . 16S rDNA and 16S rRNA single strand conformation polymorphism (SSCP) gene fingerprinting were used to fol

14. FE(III) AS ELECTRON ACCEPTOR FOR GASOLINE-ETHANOL BIODEGRADATION IN TROPICAL RESIDUAL SOIL / FE(III) COMO ACEPTOR DE ELÉTRONS NA BIODEGRADAÇÃO DE GASOLINA-ETANOL EM SOLO TROPICAL RESIDUAL
Gasoline monoaromatic hydrocarbons (BTEX) have been detected in aquifers due to storage tank spills from gas stations that lead to their consequent dissolution on groundwater. An aggravating factor in Brazil is ethanol being used as additive to gasoline, promoting an increase on pollutants percolation in soil since it works as co-solvent and is preferentiall

15. Fração endógena e recuperação urinária de derivados de purinas obtidas por diferentes métodos em bovinos nelore / Endogenous fraction and urinary recovery of purine derivatives obtained through different methods in Nelore cattle
Two experiments were executed utilizing eight Nelore heifers. The first experiment had the following objectives: aimed to evaluate the endogenous fraction at urinary excretion of purine derivatives (DP) in Nelore cattle fed single diet offering different levels of dry matter (MS); to establish the proportion of purines into abomasum recovered from urine and;

16. Caracterização de polimorfismos e atividade de enzimas relacionadas ao estresse oxidativo em linhagens bacterianas tolerantes ao herbicida mesotrione
Mesotrione, 2 - (4-mesil-2-nitrobenzoil) -1,3-cicloexanodionas, é um herbicida da classe química tricetona, com alto potencial de lixiviação, inibe competitivamente a 4-hidroxifenilpiruvato dioxigenase (HPPD), que converte a tirosina em plastoquinona e α-tocoferol, e foi encontrado em plantas, fungos e bactérias, incluindo Acinetobacter. O objetivo

17. Desempenho e avaliação nutricional de dietas contendo farelo de mamona para bovinos / Performance and nutritional evaluation of diets containing castor meal to cattle
The castor bean (Ricinus communis L.) has been traditionally cultivated in some parts of Brazil with an economic and social role. Thus, because of the high potential of productivity that this culture shows, there is a possibility to increase the use of the castor beans by- products as a protein source in ruminant diets. In order to evaluate the use of castor

18. Silagens e fenos em associação à palma forrageira para vacas em lactação e ovinos
This study was conducted to determine the performance of lactating Holstein/zebu cows fed diets based on spineless cactus with different fiber sources, namely sorghum silage, sunflower silage, guandu hay, leucena hay and elephant-grass hay. Five cows (body weight 500 kg and average milk production 12kg) were used in 5 x 5 Latin square design with 12-day peri

19. AnÃlise de comunidades microbianas de solo de manguezal por T-RFLP e microarranjos de DNA / AnÃlise de comunidades microbianas de solo de manguezal por T-RFLP e microarranjos de DNA
The mangroves are essistemas important and productive, found along the coastline of tropical and subtropical regions. Important processes such as nutrient cycling, are directly connected to the activity of soil microbial communities. Given its strategic position the mangroves are very impacted the world. In Brazil, important areas such as the Bay of All Sain

20. Nutritional evaluation of sugarcane treated with calcium oxide at different times of exposure to cattle / Avaliação nutricional da cana-de-açúcar acrescida de óxido de cálcio em diferentes tempos de amazenamento para bovinos
Were performed 4 experiments aiming evaluate the chemical composition and in vitro and in situ digestive kinetics of sugarcane treated with calcium oxide at different exposure times under nutrients intake and digestibility, performance, and ruminal parameters of Nellore heifers. The first experiment aimed to evaluate the effects of levels of inclusion and ex

21. Performance and nutritional characteristics of beef heifers in growing submitted different strategies of supplementation in grazing / Desempenho e características nutricionais de fêmeas de corte em cria e recria submetidas a diferentes estratégias de suplementação em pastejo
With the objective of evaluate the productive performance and nutritional characteristics of beef females in growing, submitted to different supplementation strategies on grazing, four experiments were conducted contemplating the periods of transition rainy-dry, dry, transition dry- rainy and rainy. In the first experiment, its was evaluated the productive p

22. Influência da alteração da distribuição do tamanho de partículas do desempenho de reatores UASB tratando esgotos domésticos
The core of this work is the development of a new concept of pre-treatment that uses the forced sieving of raw sewage as a strategy to reduce the average size of the particles and increase the conversion rates of particulate material in UASB reactors, used for treating domestic wastewater. The experimental apparatus consisted of two identical UASB reactors,
