1. KINETICS OF THE BIODEGRADATION OF MONOAROMATICS BY Pseudomonas aeruginosa
ABSTRACT Water contamination by monoaromatic compounds has risen throughout time, which leads to the necessity of developing new water treatment technology, capable of minimizing their negative effect on the environment. In this context, biological processes present themselves as a solution to the processes of extraction. Bioremediation makes use of microbia

2. MATHEMATICAL MODELING OF THE ELECTRIC CURRENT GENERATION IN A MICROBIAL FUEL CELL INOCULATED WITH MARINE SEDIMENT
Abstract Microbial fuel cells (MFC) are electrochemical devices that utilize the ability of some microorganisms to oxidize organic matter and transfer electrons resulting from their metabolism to an insoluble acceptor. The goal of the present study was to model the kinetics of electrical current generation from an MFC inoculated with marine sediment. For thi

3. INHIBITION KINETICS DURING THE OXIDATION OF BINARY MIXTURES OF PHENOL WITH CATECHOL, RESORCINOL AND HYDROQUINONE BY PHENOL ACCLIMATED ACTIVATED SLUDGE
Abstract In this work the aerobic degradation of phenol (PH), catechol (CA), resorcinol (RE), hydroquinone (HY) and of the binary mixtures PH+CA, PH+RE, PH+HY by phenol-acclimated activated sludge was studied. Single substrate experiments show a Haldane-type dependence of the respiration rate on PH, RE and HY, while CA corresponded to the Monod model. Binary

4. FormulaÃÃo MatemÃtica para CÃlculo de VariaÃÃo de ConcentraÃÃo em Escoamento EstacionÃrio / Mathematical Formulation For The Calculation Of Changes Of Concentration In Stationary Flow.
The main aim of this research is to evaluate a variation of concentration between the affluent and effluent in a biophysical or physicochemical system. The theoretical system of references used here was based upon a differential equation of steady flow, involving a chemical kinetics and a longitudinal dispersion, in which there is a number of sufficiently lo

5. Otimização dinâmica do cultivo semi-contínuo de Pichia pastoris recombinante para produção das enzimas heterólogas alfa amilase e penicilina G acilase
Este mestrado se propoe a estudar a otimizacao dinamica de biorreator automatizado, tipo tanque agitado e aerado, em escala de bancada (ate 5L), onde se processa o cultivo semi-continuo de Pichia pastoris recombinante. Essa levedura foi clonada pelo grupo do prof. Fernando Torres, da UnB, utilizando o promotor PGK1, que dispensa a utilizacao de metanol como

6. Estudo da expressão de lipase BTL2 de Bacillus thermocatenulatus em E. coli recombinante
Using recombinant DNA techniques, the lipase BTL2 gene of Bacillus thermocatenulatus was cloned in E. coli BL321 under control of the strong temperature-inducible λPL promoter. It was investigated, initially, in this work, the influence of different variables in cell growth and expression of lipase BTL2 by recombinant E. coli, through experiments perfor

7. Landfill leachate treatment in sequence anaerobic and aerobic batch reactors systems / Tratamento de lixiviados de aterros sanitários em sistema de reatores anaeróbio e aeróbio operados em batelada seqüencial
Este trabalho avaliou a tratabilidade dos lixiviados do aterro sanitário de São Carlos-SP, utilizando-se reatores biológicos. O experimento foi conduzido à temperatura ambiente, em uma unidade piloto construída no aterro sanitário de São Carlos-SP. Inicialmente foram testados e comparados dois tipos de reatores anaeróbios, cada um com volume total de

9. AvaliaÃÃo da cinÃtica de biodegradaÃÃo dos compostos tÃxicos: benzeno, tolueno, etilbenzeno, xileno (BTEX) e fenol / Evaluation of biodegradation kinetics of toxics compounds: benzene, toluene, ethylbenzene, xylene (BTEX) and phenol
Os hidrocarbonetos aromÃticos benzeno, tolueno, etilbenzeno e xilenos, coletivamente conhecidos como BTEX sÃo compostos tÃxicos presentes em derivados de petrÃleo, como a gasolina, e utilizados em larga escala nas indÃstrias quÃmicas e petroquÃmicas. Estes compostos quando liberados no meio ambiente contaminam o solo e as Ãguas subterrÃneas, podendo

10. Growth kinetic and longevity of the Kluyveromyces lactis cultures under nitrogen limitation / Cinética de crescimento e longevidade de culturas de Kluyveromyces lactis sob estresse por nitrogênio
In order to investigate the stress condition imposed by nitrogen limitation on kinetic of growth and aging of Kluyveromyces lactis, the kinetics constants of K. lactis culture as function of ammonium sulfate concentration were determined. The effect of aging of the culture on its specific initial growth rate was evaluated. Signals of aging such as cell wall

11. Estudo da transferencia de massa num reator trifasico de leito fluidizado circulante na oxidação do etanol e acido acetico com celulas imobilizadas de Acetobacter S.P
The objective of this work is the study of the kinetic and oxygen transfer in the oxidation of ethanol to acetic acid by immobilized cells, in a circulating three phase fluidized bed bioreactor. In this context experiences with Acetobacter cells, free and immobilized by entrapment in sodium aginate were done. In the first phase of the study, a strain at Acet

12. Nonlinear estimation of the parameters of Monod kinetics that best describe mineralization of several substrate concentrations by dissimilar bacterial densities.
The kinetics of mineralization of a wide range of concentrations of benzoate, glucose, and benzylamine by Pseudomonas sp., Salmonella typhimurium, and microorganisms in acclimated sewage was studied. The treatment of initial substrate concentration and population density as independent variables in nonlinear regression analysis permitted the estimation of a
