1. Ocorrência de não conformidades físico-químicas e microbiológicas em leite e derivados no estado de Minas Gerais, no período de 2011 a 2015
ABSTRACT Milk and dairy products are potential sources for spoilage and pathogenic microorganisms, and although a huge amount of data is collected by the official inspection services, only a few reports are available to the public. This study aimed to evaluate the data for physicochemical and microbiological quality of pasteurized milk and dairy products, co

3. Bartonella henselae bacteremia diagnosed post-mortem in a myelodysplastic syndrome patient
ABSTRACT This study involves a 49-year-old male, who for three years suffered with a myelodysplastic syndrome and who needed frequent blood transfusions. One day following a transfusion, he presented fever and abdominal pain. The fever became persistent and only improved temporarily with two cycles of intravenous ciprofloxacin. Nearly 120 days after beginnin

4. Effectiveness evaluation of alternative sanitizers in microbiological quality of strawberry (Fragaria ananassa Duch Var. Oso Grande) after artificial contamination by Escherichia coli
Abstract Washing and sanitization are considered particularly critical steps for the microbiological quality of fruits. At this stage, it is important to select the sanitizer which must have microbiological effectiveness. In the literature, there is a great interest on alternative sanitizers for microbiological quality control of food. This study aimed at ve

5. Effects of trees and nitrogen supply on the soil microbiological attributes on integrated crop-livestock systems
ABSTRACT The diversification of plants, as an association between trees and the warm-season grasses, supports soil biodiversity and thus, soil quality. However, based on the prevailing climatic conditions, management techniques employed and because of the several combinations possible in such associations, variations may be observed in this type of respons

6. Population Changes of Eubacteria, Sulfate-Reducing Bacteria and Methanogenic Archaea in an Anaerobic Reactor Processing Ethanol Distillery Vinasse
Abstract The microbiological characterization by molecular techniques (DGGE and quantitative PCR) of Archaea, Bacteria domain and sulfate-reducing bacteria (SRB) from a laboratory scale Up-flow Anaerobic Sludge Blanket (UASB) processing sugar cane vinasse was performed during the operational phase with increasing organic loads. The organic load removal effic

7. Characterization of different techniques for obtaining minced fish from tilapia waste
Abstract The majority of tilapia farming is used for the production of fillets, resulting in the generation of waste that can be used to increase food stocks by producing minced fish. The aim of this study was to characterize and evaluate the viability of boiling and mechanical techniques for obtaining minced fish in relation to performance, physical-chemic

8. Use of molecular techniques for the analysis of the microbiological quality of fish marketed in the municipality of Cuiabá, Mato Grosso, Brazil
ABSTRACT The present study was stimulated by the growing demand for healthy food and the technology available for the detection and identification of microbial organisms in fishery products. Molecular tools were used to identify the bacterial community and detect the presence of pathogenic species in samples of farmed and wild-caught fish. Samples of muscle

9. Morphological Diversity of Springtails in Land Use Systems
ABSTRACT: Springtails (Collembola) are soil organisms with wide morphological diversity and are sensitive to alterations in the soil, regardless of whether they are human-caused or not. The aim of this study was to evaluate the influence of land use on the morphological diversity of springtails and verify their relationships with soil physical, chemical, and

10. Classification of soil respiration in areas of sugarcane renewal using decision tree
ABSTRACT: The use of data mining is a promising alternative to predict soil respiration from correlated variables. Our objective was to build a model using variable selection and decision tree induction to predict different levels of soil respiration, taking into account physical, chemical and microbiological variables of soil as well as precipitation in ren

11. Preservation of sweet red pepper paste quality: effect of packing material, ozone gas and protective agent use
Abstract Unlike conventional methods, sweet red pepper paste was produced by various techniques in assistance of various starter cultures. Products were stored at 37 °C for 60 days. Salinity, acidity, color change, invert sugar, brown pigment formation parameters were determined during storage period. Microbiological, statistical and sensory evaluation meth

12. Culture-dependent approaches to explore the prevalence of root canal pathogens from endodontic infections
Abstract: Endodontic infections are considered to be caused by the presence of various microorganisms within the root canal system. Recognition of this microbiota contributes to the successful treatment of infected root canals. This study investigated the microorganisms associated with primary and secondary endodontic infections via culture methods, biochemi
