2. Physicochemistry, microbiology, fatty acids composition and volatile profile of traditional Söğle tulum (goat’s skin bag) cheese
Abstract Söğle cheese is a type of traditional tulum (goat’s skin bag) cheese produced from goat’s milk or a mixture of goat’s and sheep’s milk in Küçük Söğle and Büyük Söğle villages, Antalya, Turkey. This is the first study that aimed to investigate the physicochemistry, microbiology, fatty acids composition and volatile profile of tradi

3. Development of tablets containing semipurified extract of guaraná (Paullinia cupana)
This study evaluated the technological feasibility of producing a semipurified extract of guaraná (Paullinia cupana Kunth, Sapindaceae) in tablet form, using a direct-compression process. Maltodextrin and gum arabic were used to produce the extract microparticles, in order to protect the microparticles against such factors as temperature, oxidation, and hum

4. Avaliação de uma proposta contextualizada sobre o ensino de polarimetria nos cursos de farmácia e engenharia de alimentos, na Universidade Federal do Ceará
This work deals with an evaluation of an experimental application about polarimetry for pharmacy and food engineering courses. Foods obtained from the undergraduate students were used for demonstrating multidisciplinary concepts and these concepts were associated to the teaching of polarimetry. According to the results, the benefits of the contextualization

5. Post-treatment of stabilisation pond effluent by physico-chemistry process. / Pós-tratamento de efluente de lagoa de estabilização através de processo físico-químico.
Neste trabalho estudou-se o pós-tratamento de efluente de lagoa anaeróbia e lagoa facultativa por processo físico-químico à base de coagulação, floculação e separação sólido-líquido. A motivação principal para o desenvolvimento da pesquisa foi a dificuldade que os sistemas de lagoas de estabilização apresentam para atender aos limites de qua

7. Microbial, physicochemical and sensory profiles of refrigerated tilapias (Oreochromis niloticus) filets packaged under modified atmospheres / Características microbiológicas, físico-químicas e sensoriais de filés de tilápias (Oreochromis niloticus) conservados em atmosferas modificadas sob refrigeração
Estudou-se o efeito de diferentes atmosferas (vácuo, 100% CO + vácuo, 1% CO + 99% CO2) sobre a qualidade microbiológica, química, cor objetiva no sitema CIELab e sensorial de filés de tilápias (Oreochromis niloticus) estocados a 2 1 C. Os resultados foram contrastados com aqueles de filés embalados em ar atmosférico (controle). A análise microbioló

8. Vida útil dos mexilhões Perna perna cultivados no litoral norte de São Paulo: aferição dos parâmetros físico-químicos e microbiológicos. / The mussels Perna perna shelf-life cultivated in the são paulo state north coast: gauging of the physicochemistry and microbiological parameters.
The quality for consumption of the bivalve mollusks is intimately linked to the environment quality, where these are inserted. In function of the current environmental degradation caused by the growth population and consequent increase in the discharge of sewage in the environment, as well as, for the absence of quality management programs of the cultivation

9. Macadamia nacional : tocoferois e caracterização fisico-quimica . / National macadamia : tocoferois and characterization physicist-chemistry.
The macadamia nut was introduced in Brazil in 1932 and the state of São Paulo became a great national producer, being that the internal consumption of roast and salt nuts has increased as well as the exportation of the product only peeled. Due to the lack of data about the nutricional composition of the national macadâmia, this work had as objectives to ev

10. Use of Fluorescent Lectin Probes for Analysis of Footprints from Pseudomonas aeruginosa MDC on Hydrophilic and Hydrophobic Glass Substrata
Microbial footprints of Pseudomonas aeruginosa MDC attached for 1 h to clean or silanized glass were analyzed with fluorescently labeled lectin probes. Footprint composition varied, depending on cell physiology and substratum surface chemistry. This suggests that substratum physicochemistry affected the structure of cell surfaces of adsorbed organisms.

11. New Plasmid-Mediated Nucleotidylation of Aminoglycoside Antibiotics in Staphylococcus aureus
A wild-type strain of Staphylococcus aureus, which inactivates a wide variety of aminoglycosides (except the gentamicin components), has been found to harbor a plasmid (RAp01) that mediates the biosynthesis of a nucleotidyltransferase. This enzyme modifies the 4′-hydroxy function of these antibiotics. The plasmid has been studied, the enzyme responsible fo

12. Alterations in Bacillus subtilis transforming DNA induced by beta-propiolactone and 1,3-propane sultone, two mutagenic and carcinogenic alkylating agents.
Transforming DNA was exposed to either beta-propiolactone or 1,3-propane sultone and then used for transformation of competent bacteria to nutritional independence from tyrosine and tryptophan (linked markers) and leucine (an unlinked marker). The ability to transform was progressively lost by the DNA during incubation with either of these two chemicals. For
