2. Microbiological aspects of the biofilm on wooden utensils used to make a Brazilian artisanal cheese
The artisanal Minas cheese is produced from raw cow's milk and wooden utensils were employed in its manufacture, which were replaced by other materials at the request of local laws. This substitution caused changes in the traditional characteristics of cheese. Due to the absence of scientific studies indicating the microbial composition of biofilms formed on

3. Ochratoxigenic fungi associated with green coffee beans (Coffea arabica L.) in conventional and organic cultivation in Brazil
The genera Aspergillus comprises species that produce mycotoxins such as aflatoxins, ochratoxins and patulin. These are cosmopolitan species, natural contaminants of agricultural products. In coffee grains, the most important Aspergillus species in terms of the risk of presenting mycotoxins belong to the genera Aspergillus Section Circumdati and Section Nigr

5. Análise microbiológica comparativa da ação de diferentes agentes descontaminantes sobre superfícies de titânio / Microbiological comparison of different decontaminant agents on rough and smooth titanium surfaces: microbiological analysis
Actually, the titanium implants are a successful option of treatment in Dentistry. However, failures are possible to occur due to surface exposition to oral environment immediately or lately after its implantation. The titanium implants surfaces can be infected by bacteria and its products similarly to dental roots surfaces. The contaminants turn the inflamm

6. Parâmetros de qualidade e valoração de pescada da espécie Macrodon ancylodon (Bloch &Schneider, 1801): características sensoriais, físico-químicas, microbiológicas, parasitológicas e contaminantes inorgânicos / Quality and valuation parameters of king weakfish Macrodon ancylodon (Bloch &Schneider, 1801): sensorial, physical, chemical, microbiological, parasitological and inorganic contaminants characteristics
A importância do pescado no Brasil tem crescido, principalmente nos últimos 50 anos, com a criação do Ministério da Pesca e Aquicultura, o aumento da produção pesqueira e do consumo de pescado per capita. A pescada-foguete Macrodon ancylodon pertence à família Sciaenidae é um peixe de alto consumo no Brasil. A qualidade do frescor do pescado é ava

7. Perfil sócio-econômico e ambiental de doadoras de um Banco de Leite Humano no Vale do Paraíba, SP e a qualidade sanitária do leite ordenhado / Profile socio-economic and environmental of donors of a Human Milk Bank of the Vale do Paraíba, SP and the quality sanitary of the human milk orden
Human milk is free of contaminants and full of nutrients, and should remain so until consumption. However, sanitary conditions during collection and storage of milk donated to human milk banks can lead to soiling and contamination of microorganisms from the hands or the environment of the donor. The aim of this study was to assess the sanitary quality of 76

8. Microbiological evaluation of the juice from different varieties and stalk sections of sugar cane cultivated under organic management / Avaliação dos aspectos microbiológicos do caldo de diferentes variedades e partes do colmo da cana-de-açúcar sob manejo orgânico
For the artisanal cachaça production, which is a beverage obtained after distillation of the fermented sugar cane juice, natural starter ferment (caipira ferment) is utilized, in which crushed corn, rice bran and citric fruit juice are added to sugar cane juice. The primary source of microorganisms, yeasts especially, is the sugar cane juice itself, and alt

9. Identificação e descrição morfoanatômica e farmacognóstica das folhas de Solamum Scuticum M. Nee e bioatividade de extrato bruto em microorganismos e da fração alcaloídica em células cultivadas da linhagem vero / Identify and describe morphology, anatomy and Pharmacognostic sheets Solamum Scuticum M. Nee and bioactivity of microorganisms in crude extract and alkaloidal fraction in vero cells cultured strain
The jurubeba was identified that such species was Solanum scuticum M. Nee, from which pharmacognostic and morphanatomic data were not available to Goiás. Because of that, we tried some complementary data. For the morphoanatomic evaluation of the leaves some cuts were carried out as described by Kraus and Arduin (1997). For the phytochemical trial, it was us

12. Rhizospheric microorganisms and arbuscular mycorrhiza in soil from a petrochemical waste landfarming system. / Microbiota RizosfÃrica e Micorriza Arbuscular em Solo de "Landfarming" de ResÃduos PetroquÃmicos.
In the petroleum industrialization a great volume of different toxic residues is generated. Because of these waste environmental hazards they need to be adequately treated before final disposition in the environment. These wastes are usually treated by landfarming systems, but this technique has only relative success, since it doesn t completely remove all c
