Brazil processes much of its fruit by producing natural juices, candy preserves, extracts and pulps; however, almost 60% of their total weight derives from peels, leaves and seeds. As a result, the emphasis lies most strongly on the use of waste, especially waste that is not commonly used by the food industry or by consumers. The use of seeds would increase the viable sources of raw materials, lower operating costs of industries and would promote the development of new food products, since they are our main sources of protein, fat, fiber, functional compounds, vitamins and minerals salts. This paper presents alternatives for the use of pumpkin seeds (Cucurbita sp), which are often underutilized or discarded. It also demonstrates the bioactive and anti-nutritional compounds and their health effects.

This work evaluated the natural and anthropogenic influences on the quality of groundwater from public supply wells in the urban area of Marília, São Paulo State. Sixteen sampling points were established in the Adamantina Aquifer, Bauru Aquifer System, analyzing the following parameters: electrical conductivity, temperature, pH, total suspended solids, HCO3 - , PO4 3-, SO4 2-, Cl- , F- , N-NO3 - , Ca2+, Na+ , K+ , Mg2+, Si4+, Fe3+ and Al3+. The results indicated that the groundwater in the urban area of Marília has a slightly acid pH and low conductivity, with the ionic composition presenting a low cation and anion concentration and is classified as soft water and calciumbicarbonated water. Natural sources of elements/compounds can be attributed to the dissolution of carbonates during the water/rock interaction, controlling pH, alkalinity and electrical conductivity, and hydrolysis of other mineral constituents of sedimentary rocks from Adamantina Formation, with the exception of quartz. High concentrations of N-NO3 - found in some public supply wells in urban Marilia were due to sewage.

The use of geophysical methods in the analysis and mapping of likely contamination plumes has shown a huge value in the development of researches related to environmental issues. Among the main geophysical methods applied to this purpose, the geoelectrical methods stand out, being based on the use of electric and electromagnetic fields. The electromagnetic method (EM) uses physical environment responses created by electromagnetic field propagation, consisting of an alternated electric output and a magnetization force, used to obtain the electric conductivity (σ) of the subsurface materials. It has a broad application in the mineral exploration and prospection, and its use has been also efficient in environmental researches. By the electromagnetic method, this work examined and mapped possible contaminations created by cemetery leachate in the Saudade's Cemetery, located in the city of Monte Alto, Sao Paulo, where sedimentary rocks of the Bauru Group are exposed. Cemetery leachate is a putrefactive liquid, generated from the decomposition of organic matter, which contains substances that can contaminate soil and groundwater. Results achieved in this work show that the use of the electromagnetic method is an important indirect tool in the investigation of environmental contaminations in areas with highly contrasting physical properties

The city of Lençóis Paulista has a great part of its agricultural land cultivated by sugar cane and reforestation of eucalyptus and pine trees. In the county there are industries that exploit energy extracted from energy cogeneration. The city of Lençóis Paulista, in recent years, has been demonstrating considerable levels of economic and social growth with the industries that are working with sugarcane and eucalyptus mainly responsible. However, the expansion of agricultural land in many cases does not take into consideration the permanent preservation areas that are protected by the law. The APP's are of fundamental importance in the management and conservation of the environment preserving the natural plants and wildlife, and also preventing erosion and the silting of drainage networks. This objective of this study was to diagnose land use, analyze if Permanent Preservation Areas are regulated to the Brazilian Forestry Code (1965) and also diagnose areas of conflict. In relation to the use and occupation of land, the research has shown how the land is divided (agricultural crops and urban zones), and highlighted areas of conflict with the Permanent Preservation Areas. All of the information is contained in maps using Geographic Information Systems. However, it has become clear that environmental laws are not respected as much in urban areas as they are in rural areas. The PPA's are virtually nonexistent, thus creating damage to the environment and local population.

From the second half of the twentieth century, due to several factors that have attracted industries and public investments to the city, São José dos Campos has begun to stand out in the economic and industrial scenario. Consequently, the city received a big migratory flow of workers, families and those who seeked a better life, which caused the horizontal e vertical expansion of the city. With the high demand of urban spaces and increasing of property speculation, the verticalization process was necessary. Along with the constructions of new buildings, the first models of the modern architecture began to emerge

As xilanases são enzimas que hidrolisam as ligações 1,4-β-xilosídicas da xilana e que possuem potencial biotecnológico em vários processos industriais, como na clarificação de sucos e vinhos, na fabricação de pães, na produção de biocombustíveis e no tratamento das polpas celulósicas. Além disso, os produtos de hidrólise da xilana, xilooligossacarídeos, podem ser utilizados como ingredientes prebióticos, ou seja, ingredientes nutricionais não digeríveis que estimulam seletivamente a proliferação e a atividade de bactérias benéficas do cólon. O uso de enzimas microbianas nas indústrias se dá devido às suas diversas vantagens sobre os métodos químicos e à facilidade de obtenção do microrganismo. Assim, os objetivos deste trabalho foram: produzir e caracterizar parcialmente a xilanase de Aspergillus sp isolado de pó de café utilizado, purificar parcialmente a enzima produzida e analisar os produtos de hidrólise da xilana. O Aspergillus sp mostrou-se bom produtor de xilanase quando o pó de sabugo de milho foi utilizado como fonte de carbono e a xilanase produzida apresentou melhor atividade específica quando o período de cultivo foi de 168 horas. Os processos de precipitação de proteínas e diálise promoveram o aumento da atividade específica do extrato. A xilanase de Aspergillus sp apresentou pH e temperatura de máxima atividade semelhantes aos de produzidas por Aspergillus niger isolados de outras fontes. A hidrólise da xilana produziu xilose e xilooligossacarídeos. Além da xilanase, o fungo revelou ser produtor de outras proteínas que podem ser estudadas em pesquisas futuras.
