Última Antimicrobial activity of microcapsules with aqueous extract of chambá (Justicia pectoralis Jacq) Rev. Ciênc. Agron. Guimarães,Thays Lima Fama; Silva,Larissa Morais Ribeiro da; Lima,Carolline de Brito; Magalhães,Francisco Ernani Alves; Figueiredo,Evânia altina Teixeira de. ABSTRACT To ensure the antimicrobial activity of the aqueous extract of chambá, it is essential to protect its bioactive compounds. The objective was to preserve its characteristics, aiming to provide the food industry with a natural antimicrobial. Three microcapsule formulations made with maltodextrin and cyclodextrin were developed, both including the aqueous extract of chambá leaves dried through lyophilization. The aqueous extract was initially submitted to in vivo toxicity analysis using zebrafish and the microcapsules were characterized through studies of morphology, hygroscopicity, water solubility, particle size, zeta potential, color determination, microencapsulation efficiency and antimicrobial activity. The aqueous extract of chambá was not... Tipo: Info:eu-repo/semantics/article Palavras-chave: Aqueous extraction; Chambá leaves; Microencapsulation; Zebrafish; Microdilution.

ABSTRACT Plant residues and certain fertilizers accelerate soil acidification and increase the levels of aluminum-Al+3 in soils under no-tillage (NT). Silicates act as acidity amendments and as a source of silicon as in H4SiO4. An increase in the pH of soil solution causes the deprotonation of H4SiO4 and generates the anionic form (H3SiO4−). The aim of this study was to evaluate the ionic speciation of Si, Al, Ca, Mg and K in aqueous extracts by means of a software calculation. Since 2006, a field experiment has been under way on an Oxisol under NT subjected to lime and calcium-magnesium silicate applications under four crop systems. The amendments were applied in Oct 2006 and in Oct 2011, aiming to raise base saturation to 70 %. Soil samples were...
