1. Comparative Study of Degradation of Reactive Dyes and Decolorization and Detoxification in Aqueous Solution Applying DyP Peroxidases Isolated from Saccharomonospora viridis (SviDyP) and Thermobifida fusca (TfuDyp)
The wastewater that originates from the widespread usage of synthetic dyes in the industry have become a severe environmental problem. Several efforts have been made to develop new types of treatment which are capable of performing the degradation of the dyes from the environment. Within this scope, much attention has been drawn to enzymatic approaches, main

2. Geochemical Investigation of Tar Balls Collected in a Brazilian Beach Using Biomarkers, Ni/V, δ13C Ratios and Ultra-High Resolution FT-ICR Mass Spectrometry
Representative tar balls collected in two distinct years (2012 and 2014) in a beach along the State of Bahia, northeastern Brazil, were geochemically characterized in order to identify correlations between them and investigate potential sources. Terpanes and steranes biomarkers (detected by gas chromatography coupled to mass spectrometry, GC-MS), carbon stab

3. 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

4. Denaturation processes of collagen from cow bones as a function of temperature
ABSTRACT The thermal stability of collagen is of great interest for the scientific communities both of medicine and archaeology. In medicine, the interest is focused to the reconstruction and repair of bone and cartilage, given the frequency and importance of pathological situations. In contrast, in archaeology the interest is focused to infer from buried an

5. Polymers and its applications in agriculture
Graphical Abstract Abstract Polymers are a class of soft materials with numerous and versatile mechanical and chemical properties that can be tuned specific to their application. Agriculture is an expanding area due to the requirement for indispensable food to meet the demands of a growing global population. Consequently, development of technology to imp

6. BIODEGRADACION FUNGICA DE POLIURETANO RÍGIDO
Polyurethane (PU) is one of the most widely used polymer materials. This generates a serious environmental problem because of its poor biodegradability since most of the native microorganisms cannot use it as a source of nutrients. Several techniques involving mechanical and chemical processes have been used for its recovery and reuse; however, the problem o

7. FÁRMACOS QUIRAIS EM DIFERENTES MATRIZES AMBIENTAIS: OCORRÊNCIA, REMOÇÃO E TOXICIDADE
In recent decades, the occurrence of pharmaceuticals in the environment has been widely reported due to their high frequency and recalcitrance in many cases. Concerning the chiral pharmaceuticals (CPs) in environmental matrices, the stereochemistry is often neglected and enantiomers are determined together as unique molecules. However, it is well known that

8. Analysis for the presence of determinants involved in the transport of mercury across bacterial membrane from polluted water bodies of India
Abstract Mercury, which is ubiquitous and recalcitrant to biodegradation processes, threatens human health by escaping to the environment via various natural and anthropogenic activities. Non-biodegradability of mercury pollutants has necessitated the development and implementation of economic alternatives with promising potential to remove metals from the e

9. DEPLOYMENT OF METHOD FOR ANALYSIS OF STABLE CARBON ISOTOPES (N-ALKANES C1-C5) IN GAS SAMPLES AT LOW CONCENTRATIONS / IMPLANTAÇÃO DE MÉTODO PARA ANÁLISE DE ISÓTOPOS ESTÁVEIS DE CARBONO (N-ALCANOS C1-C5) EM GASES A BAIXAS CONCENTRAÇÕES
The concentration and isotopic composition of n-alkanes C1-C5 has revealed as a powerful tool for interpretation of interesting processes in the oil exploration industry, studies of global climate change, oil biodegradation and carbon cycle elucidation. In this context, studies about methane analysis have been distinguished and multiplied due to the importan

10. Modelagem Matemática da produção e transporte de biogás em aterros sanitários / Mathematical modeling of production and transportation of biogas in landfills
The processes that occur within the landfill for the production of methane are the methane generation through biodegradation, transport of methane through a porous medium and sorption of methane through reactions with other compounds present in the landfill, especially oxidation. This work aims to develop a computer model to estimate the biogas production ra

11. Aplicação do modelo Tucker-3 para a análise da biodegradação de diesel
Tucker-3 model offers several advantages for analysis of environmental data but its interpretation is still challenging. A Tucker-3 model was applied to a biodegradation experiment involving a large number of overlapped chromatographic peaks and a temporal variation. The Tucker-3 model allowed the data to be decomposed in two processes: evaporation and biode

12. ANTI-INFLAMATÓRIO DEXAMETASONA: ESTUDOS DE BIODEGRADABILIDADE, TOXICIDADE, OCORRÊNCIA E DEGRADAÇÃO OXIDATIVA AVANÇADA EM EFLUENTE HOSPITALAR / ANTI-INFLAMMATORY DEXAMETHASONE: STUDIES OF BIODEGRADABILITY, TOXICITY, OCCURRENCE AND ADVANCED OXIDATIVE DEGRADATION IN HOSPITAL EFFLUENT
A presença de fármacos e substâncias ativas no ambiente vem sendo causa de preocupação nos últimos anos. Uma gama destes compostos tem sido encontrada em águas tratadas em estações de tratamento de efluentes, águas superficiais e, menos frequentemente, em águas subterrâneas, em todo o mundo. A Dexametasona (DEX), um anti-inflamatório análogo à
