13. Identificação de actinomicetos isolados de solo impactado com resíduos petroquímicos e seleção de potenciais degradadores de misturas de diesel e biodiesel
Actinomycetes are Gram positive bacteria, predominantly filamentous, mainly found in soil. Few studies assess their ability for fuel degradation, although some authors state that they are good candidates for hydrocarbon bioremediation application. The main objectives of this study were to identify actinomycetes obtained from petroleum hydrocarbon contaminate

14. Diversity of 16S rRNA genes from bacteria of sugarcane rhizosphere soil
Sugarcane is an important agricultural product of Brazil, with a total production of more than 500 million tons. Knowledge of the bacterial community associated with agricultural crops and the soil status is a decisive step towards understanding how microorganisms influence crop productivity. However, most studies aim to isolate endophytic or rhizosphere bac

15. Inhibitory activity of root canal irrigants against Candida albicans, Enterococcus faecalis and Staphylococcus aureus
The present study evaluated the antimicrobial activity of three root canal irrigants against Enterococcus faecalis, Candida albicans, and Staphylococcus aureus. These microorganisms were incubated in the presence of citric acid (6 and 10%), EDTA (17%), and NaOCl (0.5, 1.0, 2.5, and 5.25%). Agar diffusion tests were performed and redox indicator resazurin was

16. Screening for antimicrobial activity among bacteria isolated from the amazon basin
Bacteria producing antimicrobial activity were identified among 86 isolates from aquatic environments of Brazilian Amazon Basin. Antimicrobial activity against at least one indicator strain was detected for 59 isolates (68.6%). Inhibitory activity was mostly against Gram-positive bacteria, such as Listeria monocytogenes and Bacillus cereus. The antimicrobial

17. Solubilization of phosphorus by endofhytic bacteria / Solubilização de fósforo por bactérias endofíticas
Soil microorganisms directly affect fertility and plant yield. Among these, inorganic phosphate solubilizers enhance phosphorus availability, and may increase phosphorus fertilizers efficiency. This work aimed to select inorganic phosphorus solubilizing bacteria as potential plant growth promoters. On the first stage, previously obtained isolates, from leave

18. Avaliação da utilização de colifagos como indicadores virais a partir da análise de enterovírus e adenovírus em efluentes tratados por diferentes processos biológicos
Domestic sewage contains a high amount of bacteria and other pathogens and non pathogens that are discharged into water bodies. Contamination of water by the presence of pathogenic bacteria and viruses, brings undesirable consequences, especially for public health. The objective of this work was to evaluate the possibility of using analysis of coliphages as

19. Atributos biológicos e químicos de um solo cultivado com cana-de-açúcar (Saccharum officinarum L.) fertirrigado com vinhaça / Biological and Chemical Attributes of a Soil Cultivated with Sugar-cane (Saccharum officinarum spp) fertirrigated with vinasse.
The agriculture has come to pass by big changes that include the introduction of synthetic chemical products, the use of more refined machinery, the diminution of the diversification of cultures and the emergency of more specialized and large-scale producers. Consequently, in the evolution of the man and the environment relation, the environmental imbalances

20. Characterization, treatment and reuse of greywater and rainwater use in buildings. / Caracterização, tratamento e reúso de águas cinzas e aproveitamento de águas pluviais em edificações.
The reuse of greywater and the rainwater catchment for non potable uses meets the premises of sustainability and the concept of water conservation. Properly conceived greywater reuse systems and rainwater catchment systems should follow four basic criteria: hygienic reliability, aesthetics, environmental protection and technical/economic feasibility. The gre

21. Adenovirus molecular detection and seasonal monitoring in bodies of water in the municipality of Goiânia, Goiás-Brazil: correlation with physical-chemical and bacteriological parameters and meta-analysis to evaluate methodologies / Detecção molecular e monitoramento sazonal de adenovírus em águas fluviais no município de Goiânia, Goiás-Brasil: correlação com parâmetros físico-químicos, bacteriológicos e Metanálise avaliativa de metodologias
Although water is of vital importance for living beings, due to antropic action it becomes a way of dissemination of several microorganisms, which reach aquatic environments through the faeces of man and other animals and can cause several illnesses, especially for immunocompromised individuals. During routine environmental monitoring, coliform bacteria are

22. Antagonistic properties of some microorganisms isolated from Brazilian tropical savannah plants against Staphylococcus coagulase-positive strain
Endophytic microorganisms are relatively unstudied as potential sources of novel natural products for medical and commercial exploitation. The aim of this work was to investigate some Brazilian tropical savannah trees Cassia leptophylla and Prunus spp. in order to isolate the endophytic microorganisms associated with these plants. The samples were disinfecte

23. Pesquisa de microorganismos indicadores e patogênicos no filé de tilápia do Nilo (Oreochromis niloticus) e em diferentes pontos da planta de processamento
Nile tilapia (Oreochromis niloticus) is one of the most important species for aquaculture because of its easily adaption to farming in different production systems, delicate taste and texture. However, there are not many slaughterhouses for Nile tilapia in Brazil because the production is still small and targeted mainly to local trade. The purpose of this st
