Ozonólise das ligninas organossolve e kraft eucalipto. Parte II: cinética nos meios ácido e básico Ozonolysis of organosolv and kraft eucalyptus lignins. Parte II: kinetic in basic and acid media

Autor: Evandro A. Nascimento, Sérgio A. L. Morais, Francisco J. T. Aquino, Dorila Piló - Veloso

Publikováno v: Química Nova, Vol 21, Iss 5, Pp 578-583 (1998)

Organosolv and kraft lignins were treated with ozone both in basic and acid media and the reaction was studied kinetically. In contrast to reported studies, ozone was more efective in basic medium. Kraft lignin was degraded faster than organosolv lig

Effects of the substitution of amino acid residues, through chemical synthesis, on the conformation and activity of antimicrobial peptides

Autor: Regina C. Adão, Victor Hugo O. Munhoz, Bianca Matos Oliveira Mendes, Jarbas M. Resende, Dorila Piló-Veloso

Publikováno v: Orbital: The Electronic Journal of Chemistry, Vol 4, Iss 1, Pp 69-71 (2012)

Antimicrobial peptides make up an assorted group of molecules which contain from 12 to 50 amino acid residues and which may be produced by microorganisms, plants and animals. From the discovery that these biomolecules are lethal to bacteria, inhibiti
