1. Influence of sorbitol on mechanical and physico-chemical properties of soy protein-based bioplastics processed by injection molding
Abstract Soy Protein Isolate (SPI) has been evaluated as useful candidate for the development of protein-based bioplastic materials processed by injection molding. The influence of sorbitol (SB) as plasticizer in mechanical properties and water uptake capacity was evaluated in SPI-based bioplastics. A mixing rheometer that allows monitoring torque and temper

2. Study of oxide nanoparticles as additives for vegetable lubricants
Currently, vegetable oils have been studied as biolubricants in order to reach new environmental standards. Besides being non-renewable, mineral oils from petroleum bring consequences to the environment due to its low biodegradability. Thus, the aim of this work is to develop a biolubricant and to add oxide nanoparticles (ZnO and CuO) in order to improve abr

3. Avaliação da biodegradabilidade de petróleo utilizando microrganismos isolados do estuário do Rio Potengi (RN)
A atividade petrolífera do RN constitui uma ameaça permanente aos ecossistemas costeiros, principalmente os manguezais, com a possibilidade de derramamentos de óleo. Neste contexto, o objetivo desse estudo foi avaliar o potencial de resistência do ambiente de manguezal a um possível derramamento. Foram selecionados e isolados microrganismos degradadores

4. Avaliação cinética da produção de biossurfactantes bacterianos
Biosurfactants present advantages in relation to the synthetic surfactants, as the biodegradability and low toxicity, and can be applied in the food industry, in pharmaceutical products, cosmetics and in the petroleum recovery. This paper aimed at selecting bacteria for biosurfactant production, evaluating the surface tension and the emulsifying activity and

5. Biodegradação de polietileno tereftalato (PET) por fungos ligninoliticos / Biodegradation of polyethylene tereftalate by ligninolytic fungi
In 1977, polyethylene terephthalate (PET), a plastic derived from petroleum, started to be used as raw material for packaging material and engineering plastics. However, under an environmental point of view, the use of plastics is considered problematic because of their high durability and high volume when present in domestic and industrial solid wastes. Thi

6. Estudo da influência de compostos recalcitrantes na remoção de matéria orgânica biodegradável no tratamento de efluente de refinarias de petróleo / Studies of hard-to-degrade compounds influence on removal of biodegradable organic material from petroleum refinery wastewaters
Petroleum Refinery wastewaters (PRW) have hart-to-degrade compounds, such as: phenols, ammonia, cyanides, sulfides, oils and greases and the mono and polynuclear aromatic hydrocarbons: benzene, toluene and xylene (BTX), acenaphthene, nitrobenzene and naphtalene. It is known that the microrganisms activity can be reduced in the presence of certain substances,

7. Effects of Temperature and Crude Oil Composition on Petroleum Biodegradation
The biodegradability of seven different crude oils was found to be highly dependent on their composition and on incubation temperature. At 20 C lighter oils had greater abiotic losses and were more susceptible to biodegradation than heavier oils. These light crude oils, however, possessed toxic volatile components which evaporated only slowly and inhibited m
