Campos, Nícolas Mateus Cosme Oliveira; Jesus, Raildo Mota de; Santana, Gregório MateusThe vulnerability shown by the pandemic caused by SARS-CoV-2, sparked a concern in the world population in establishing emergency containment measures. Although, so far, few studies have established sanitary sewage as a way of contamination by SARS-CoV-2, in Brazil the instability of wastewater disposal has established a warning about the inability of public systems to provide the implementation of collection a...
Production and performance of physically activated carbon from Bambusa vulgaris
Morais, Rayssa de Medeiros; Santana, Gregório Mateus; Costa Lelis, Roberto Carlos; Paes, Juarez Benigno; Schueler, Maria Vanessa EggerActivated carbon (AC) was produced from Bambusa vulgaris to evaluate its potential of methylene blue dye (MB) adsorption. AC was prepared by direct physical activation, using the water vapor as activating agent. It was characterized considering the gravimetric yield of AC, the pH point of zero charge, Boehm titration method, surface area, volume and pore diameter analysis and superficial morphology. The applica...
Tannins: main component of the extract Piptadenia stipulacea (Benth) Ducke inhi...
Cavalcanti-Dantas, Vanessa de Melo; Medeiros, Kézya Lopes de; Azevêdo, Tatiane Kelly Barbosa de; Santana, Gregório Mateus; Pereira, Andréia VieiraThis study evaluates the antimicrobial activity of tannins observed on the stem bark of Piptadenia stipulacea (Benth) on Staphylococcus aureus strains of bovine origin. In vitro antimicrobial activity of the tannin was evaluated by determining the minimum inhibitory concentration (MIC). To determine the MIC, tannins were serially dissolved in distilled water at concentrations ranging between 500 mg/mL and 0.976...
