Cabacinha cheese from Vale do Jequitinhonha is similar mozzarella, but in this milk is crude, being the product is stored at ambient without packaging. Besides it contributes to local income, customers may be food-poisoned. The objective of this study was to verify the physical-chemical and microbiological characteristics of samples of Cabacinha cheese produced and marketed in Vale do Jequitinhonha-MG. Samples were bought in tents (n=25), restaurants (n=4) and bakeries (n=2) located by BR 251 and BR 116 highways in the towns of Medina, Cachoeira de Pajeú and Pedra Azul. Cheeses from 17 marketplaces were purchased from the first town, 10 from the second and 4 from the third, respectively. The coliforms at 35ºC, Escherichia coli, coagulase positive Staphylococcus, lactic acid bacteria, filamentous fungi and yeasts were 1.8 x 103; 1 x 101; 4.6 x 103; 6.3 x 107 and 4.9 x 106 Colony Forming Units per gram, respectively, and Salmonella spp. are absent. The chemical characteristics mean was 26.47% of protein, 27.69% of fat, 4.34% of minerals, 36.23% of moisture, 843.66 mg/100g of sodium and pH of 5.14. This is the first paper that describes microbiological and chemical characteristics of Cabacinha cheese from Vale do Jequitinhonha. The absence of regulations for microbiological parameters may put the health of consumers at risk.

The aim of the present study was to evaluate chemical and microbiological parameters of industrialized and artisanal bacuri (Platonia insignis Mart) and cupuaçu (Theobroma grandiflorum Schum) pulps, native Brazilian Amazon fruits. Several fruit pulp brands were selected as follows: industrialized pulps (IP), brands A and B and artisanal pulps (AP), brands C and D. The chemical analyses were based on the determination of initial pH, total titratable acidity (TTA), total soluble solids (TSS) and their ratio (TSS/TTA). Microbiological analyzes quantified mold, yeast, Staphyloccus aureus and Salmonella spp. Their contamination were also determined. Chemical characterization demonstrated that bacuri pulps had lower level of TTA and TSS than cupuaçu pulp. However, ration between TSS and TAA showed higher level in bacuri pulp/brand AP/D. The microbiological analyses showed a ranging from 2.83x105 to 9.35x107 and 7.32x106 to 7.06x107 mold and yeast colony forming units (CFU/g) for bacuri and cupuaçu pulps, respectively. All pulps presented high amounts of Staphylococcus aureus. The presence of Salmonella was verified in industrialized pulp for both bacuri and cupuaçu fruits. We concluded that both industrialized and artisanal bacuri and cupuaçu pulps have poor microbiological food quality, indicating a health threat to the consumers.

The physical–chemical characterization of natural and synthetic historical inorganic and mineral pigments, which may be found embedded in paintings (real or mock-ups), glass, enamel, ceramics, beads, tesserae, etc., as well as their alteration under different decay scenarios, is a demanding line of investigation. This field of research is now both well established and dynamic, as revealed by the numerous publications in high-quality journals of varied scientific disciplines. [...]

Due to the increase in the consumption of natural products, there has been a growing use and commercialization of bee pollen, thus, the need for a greater quality control regarding the physical-chemical and microbiological characteristics of this product is justified. In this way, the research aimed to determine the physical-chemical, microbiological and sensorial characteristics of four brands of dehydrated pollen, marketed in natural products houses in different parts of the city of Belém-Pará. Microbiological (aerobic mesophilic bacteria, fungi and yeasts, Coliformes at 45°, Salmonella sp and Staphylococcus aureus) and sensorial analyzes were carried out in the physicochemical analyzes (moisture, ashes, lipids, proteins, pH, free acidity, total sugars). The results obtained were within the parameters of quality allowed by the Brazilian legislation for dehydrated pollen. Regarding the microbiological analysis, all brands showed absence of Staphylococus aureus and Salmonella spp. For the sensorial analysis, the C mark presented better results for both flavor and aroma, confirming the quality of the dehydrated pollen commercialized in Belém-Pa.

<p>Nos últimos anos, a preocupação com as questões ambientais vem sendo bastante discutidas, onde merece destaque, o descarte indevido do esgoto doméstico no meio ambiente, portanto o presente estudo objetivou realizar a caracterização físico-química e microbiológica do esgoto descartado no solo, no Centro de Ciências e Tecnologia da Universidade Estadual da Paraíba, campus de Campina Grande – PB. Para tanto foram desenvolvidas análises físico-químicas, tais como pH, Fósforo Total, DBO, DQO, Nitratos, Nitritos, Nitrogênio Amoniacal, Orto-Fosfatos e Alcalinidade, bem como análise microbiológica (coliformes). Observou-se que o efluente na unidade em questão não recebe tratamento para seu descarte, sendo identificadas características físico-químicas e microbiológicas de esgoto <em>in natura</em>. Faz-se necessário desta forma, investimentos em análises periódicas para assim realizar um tratamento adequado ao efluente visando-se reduzir os riscos ambientais e de saúde pública. Após os resultados das análises, foi proposto, além do tratamento preliminar, um tratamento biológico para o efluente, do tipo, lagoa facultativa primária seguida de duas lagoas de maturação, onde a eficiência do tratamento nos parâmetros analisados se enquadra aos padrões estabelecidos pelo CONAMA 430/2011, na qual o efluente pós - tratado poderia ser reutilizado para fins menos nobres, destinando a água potável para atividades que requerem uma qualidade melhor.</p><p><strong><em>Physicochemical and microbiological characterization of wasterwater of the UEPB with proposed of treatment for reuse purposes</em></strong></p><p><strong>Abstract</strong><strong>: </strong>In recent years, concern about environmental issues has been widely discussed, which deserves mention the improper disposal of domestic sewage into the environment, so this study aimed to perform the physicochemical and microbiological sewage discarded the soil, in the Science and Technology Center of the State University of Paraiba, campus of Campina Grande - PB. Therefore, we developed physical-chemical analysis such as pH, Total Phosphorus, BOD, COD, Nitrate, Nitrite, Ammonia Nitrogen, Orto-Phosphates and alkalinity, as well as microbiological analysis (coliforms). It was noted that the effluent in the unit in question does not receive treatment for their disposal, identified physical, chemical and microbiological characteristics of raw sewage. It is necessary therefore, investment in periodic reviews thus to carry out an appropriate treatment to effluent aiming to reduce environmental risks and public health. After the analysis results, it was proposed, in addition to preliminary treatment, a biological treatment for the effluent, type, primary facultative pond followed by two ponds maturation, in which the treatment efficiency in the analyzed parameters falls within the standards set by CONAMA 430/2011 in which the effluent post-treaty could be reused for less noble purposes, intended to clean water for activities that require a better quality<strong>.</strong></p>
