1. Shelf-life of loricariid catfish (Pterygoplichthys disjunctivus [Weber, 1991]) roe stored in ice
Abstract Loricariid catfish (Pterygoplichthys disjunctivus [Weber, 1991]) has invaded water catchments throughout the world, due to the lack of predators and high fecundity. An approach to control its population could be using its roe as food; however, more knowledge is needed. Thus, the present study aimed to evaluate the shelf-life of fresh loricariid catf

2. Functional sirkencubin syrup with purple basil; bioactive properties, organoleptic acceptability, and possible effects on blood pressure
Abstract Sirkencubin syrup is a health-friendly alternative drink consisting of a mixture of honey, vinegar and water. In this study, purple basil sirkencubin syrup and the changes in sirkencubin syrup during two months storage period (1, 10, 20, 30 & 60 days) were investigated. Physicochemical properties, bioactive properties, organoleptic properties, gener

3. Improving composition and microbiological characteristics of milk kefir using colostrum
Abstract Kefir characteristics are influenced by raw materials. Fresh milk and colostrum have different characteristics. In this research, colostrum was used as additional material in kefir production which could affect the chemical, microbiological, and antimicrobial properties of final the product. This study was aimed to investigate the chemical and micro

4. Characterization of physicochemical composition, microbiology, sensory evaluation and microscopical attributes of sweetened condensed milk
Abstract An analysis of nine sweetened condensed milk brands allowed for the identification of statistically significant difference in moisture, water activity (aw), soluble solids, percentage of protein, lactose crystals size, viscosity and in sensorial attributes of texture, characteristic flavor and flour texture. Relevant correlations between the composi

5. The Matrix-Assisted Laser Desorption Ionization-Time of Flight Mass Spectrometry (MALDI-TOF MS) identification versus biochemical tests: a study with enterobacteria from a dairy cattle environment
Abstract Mastitis adversely affects milk production and in general cows do not regain their full production levels post recovery, leading to considerable economic losses. Moreover the percentage decrease in milk production depends on the specific pathogen that caused the infection and enterobacteria are responsible for this greater reduction. Phenotypic test

6. Evaluation of the microbiological quality of ricotta cheese commercialized in Santa Catarina, Brazil
Abstract Ricotta cheese has low fat and salt contents and a high quantity of proteins. The diversity of the nutrients and the high water content are factors that favor the development of microorganisms in this product. In this context, the aim of this study was to evaluate the microbiological quality of ricotta commercialized in the western region of Santa C

8. Incidência microbiana e medidas preventivas de contaminação em superfícies de um centro cirúrgico
The composition and concentration of microorganisms are extremely important components to demonstrate the level of hygiene in hospital operating rooms. The information from these strategies can be developed to maintain a biologically safe hospital environment by eliminating the focus of contact and transmission, and thus preventing nosocomial infections that

10. Efeito do ácido lático sobre as características microbiológicas, físico-químicas e sensoriais na carne do sol
The dried beef is a food traditionally eaten by Northeastern and has an extensive trade in the city of Natal-RN. It is usually produced in an empirical manner, without any standardization in production. Characterized as partially dehydrated meat product, so that the activity of water present is not sufficient to prevent microbial growth, degradation or the p

11. A procura de bactérias degradadoras de metamidofós. / Searching for methamidofos degrading bacteria.
Methamidophos is a strong acetylcholinesterase inhibitor and, therefore, a very toxic organophosphorus insecticide. This product has been widely employed for pest control in a variety of cultures, but little information is available about its biodegradation. 12 bacteria were isolated and characterized, from water and soil samples obtained from a site contami
