1. GPo1
alkB gene expression for improvement of the degradation of diesel oil by a bacterial consortiumTo facilitate the biodegradation of diesel oil, an oil biodegradation bacterial consortium was constructed. The alkane hydroxylase (
alkB ) gene ofPseudomonas putida GPo1 was constructed in a pCom8 expression vector, and the pCom8-GPo1alkB plasmid was transformed intoEscherichia coli DH5Braz. J. Microbiol.. Publicado em: 2015-09

2. Biodegradation of crude oil by individual bacterial strains and a mixed bacterial consortium
Three bacterial isolates identified as Alcanivorax borkumensis SK2, Rhodococcus erythropolis HS4 and Pseudomonas stutzeri SDM, based on 16S rRNA gene sequences, were isolated from crude oil enrichments of natural seawater. Single strains and four bacterial consortia designed by mixing the single bacterial cultures respectively in the following ratios: (Alcan

3. Effect of biologically treated petroleum sludge on seed germination and seedling growth of Vigna unguiculata (L.) Walp. (Fabaceae)
The present investigation was carried out to study the response of different concentrations of treated petroleum sludge on seed germination, root and shoot length and tolerance of Vigna unguiculata (L.) Walp. The biologically treated petroleum sludge with bacterial consortium showed 54.8% reduction in total petroleum hydrocarbons. Treated sludge was utilized

4. The behaviour of an anaerobic baffled reactor (ABR) as the first stage in the biological treatment of hog farming effluents
This present paper reports a study of the efficiency of an anaerobic Baffled Reactor (ABR) composed of three chambers working as the first stage of a biological treatment system for swine wastewater, over a period of 116 days. The average value of the volumetric organic loading rate (VOLR) was 17.8 kgCODtotal m-3 d-1, the biological organic loading rates (BO

5. Characterization of pyrene utilizing Bacillus spp. from crude oil contaminated soil
Pyrene, a high molecular weight polycyclic aromatic hydrocarbon (PAH), is a priority pollutant present in soil contaminated with crude oil, coal-tar and complex PAHs. Bacterial consortium CON-3 developed from crude oil contaminated soil of Patiala, Punjab (India) cometabolized 50 µg ml-1 pyrene in the presence of glucose (0.5 %; w/v) at 30 °C, as determine

6. Biosurfactants production by yeasts using soybean oil and glycerol as low cost substrate
Biosurfactants are bioactive agents that can be produced by many different microorganisms. Among those, special attention is given to yeasts, since they can produce many types of biosurfactants in large scale, using several kinds of substrates, justifying its use for industrial production of those products. For this production to be economically viable, the

7. Eficiência do uso da terra na associação de culturas para produção de Bio-Óleo / Efficiency of land use in the crop association to produce Bio-Oil
Um experimento de campo foi desenvolvido na Fazenda Morrinhos, município de Nísia Floresta, RN com o objetivo de desenvolver um sistema de manejo para oleaginosas visando a produção de biodiesel. Neste sistema, o coqueiro híbrido (Cocos nucifera L.) é a cultura principal, sendo associada com girassol, mamona, amendoim, pinhão manso e soja sob cultivo

8. Interações e viabilidade do plantio consorciado de pinhãomanso (Jatropha curcas) e girassol (Helianthus annuus L.) / Feasibility and interactions of intercropping planting of physic nut (Jatropha curcas l.) and sunflower (Helianthus annuus l.)
With the recent advent of biodiesel in Brazil, there has been a significant increase in the number of research on the potential of utilizing oleaginous as raw material, especially in physic nut (Jatropha curcas L.), due to its superior oil technical characteristics, as well as the plants hardiness and productivity. However, since the production of physic nut

9. Utilização de consorcio microbiano para biorremediação do meio ambiente contaminado com derivados de petroleo. / The use of a microbial consortium for biorremediation of oil derivatives contaminated environment.
Neste trabalho foi formulado um consórcio microbiano para avaliação de seu potencial em degradar petróleo e seus derivados, em microcosmos e meio mínimo de sais. As 43 bactérias testadas na primeira fase do projeto demonstraram alguma propriedade que as classificam como potencialmente degradadoras de hidrocarbonetos. Todavia, as cepas 1, 9, 22, 23 e 36

10. Parallel Characterization of Anaerobic Toluene- and Ethylbenzene-Degrading Microbial Consortia by PCR-Denaturing Gradient Gel Electrophoresis, RNA-DNA Membrane Hybridization, and DNA Microarray Technology
A mesophilic toluene-degrading consortium (TDC) and an ethylbenzene-degrading consortium (EDC) were established under sulfate-reducing conditions. These consortia were first characterized by denaturing gradient gel electrophoresis (DGGE) fingerprinting of PCR-amplified 16S rRNA gene fragments, followed by sequencing. The sequences of the major bands (T-1 and

11. Evaluation of Inoculum Addition To Stimulate In Situ Bioremediation of Oily-Sludge-Contaminated Soil
A full-scale study evaluating an inoculum addition to stimulate in situ bioremediation of oily-sludge-contaminated soil was conducted at an oil refinery where the indigenous population of hydrocarbon-degrading bacteria in the soil was very low (103 to 104 CFU/g of soil). A feasibility study was conducted prior to the full-scale bioremediation study. In this
