- Abstract:
- ... Ethyl alcohol 70% (w/w) is a broad-spectrum bactericidal agent that is mandatorily marketed as a gel in Brazil since 2002. However, there is no method described for the microbiological quality control of surface disinfectants in the form of gel, which makes it impossible to monitor the effectiveness of these products by the Health Surveillance. Thus, the present study aimed to adapt an analytical ...

- Abstract:
- ... This study describes the first antibiofilm and antibacterial screening for plants from Caatinga against Ralstonia solanacearum, a causal agent of bacterial wilt that presents serious difficulties in control. There were prepared 22 aqueous extracts of plants collected in the Vale do Catimbau—PE, Brazil. The potential antibacterial activity was evaluated by absorbance in OD₆₀₀ and the antibiofilm ac ...

- Abstract:
- ... Lafoensia pacari A. St.-Hil., (Lythraceae) is a native tree of Brazilian Cerrado and commonly known in Brazil as "mangava-brava". Its leaves are used in Brazilian folk medicine in wound healing, cutaneous mycoses, and in the treatment of gastritis and ulcers.The present study was designed to evaluate the wound healing activity and mechanism of action of the hydroethanolic extract of Lafoensia paca ...

- Abstract:
- ... The objective of this study was to determine physicochemical and phenolic profiles as well the antioxidant and antimicrobial capacities of monofloral bee pollen samples from Brazil. Traditional methods were used. The phenolic profile was determined by high‐performance liquid chromatography‐mass spectrometry (HPLC‐MS). The protein (10.6–33.9 g/100g), lipids (3.2–8.3 g/100g), ashes (2.6–3.8 g/100g), ...

- Abstract:
- ... This study investigated the chemical composition, flavonoids, phenolic compounds, antioxidant activity and antibacterial activity of commercial propolis extracts produced in the Sergipe and Alagoas States of Brazil as potential bioproducts for the food and pharmaceutical industries. Four samples were analyzed, three brown propolis extracts and one red propolis extract, and were characterized throu ...

- Abstract:
- ... Artisanal raw milk cheeses are highly appreciated dairy products in Brazil and ensuring their microbiological safety has been a great need. This study reports the isolation and characterization of lactic acid bacteria (LAB) strains with anti-listerial activity, and their effects on Listeria monocytogenes during refrigerated shelf-life of soft Minas cheese and ripening of semi-hard Minas cheese.
