Kinetics of Eucalypt Lignosulfonate Oxidation to Aromatic Aldehydes by Oxygen i...
Santos, Sonia G.; Marques, Ana P.; Lima, Diana L. D.; Evtuguin, Dmitry V.; Esteves, Valdemar I.The oxidation kinetics of lignosulfonates (LS) from acidic magnesium-based sulfite pulping of Eucalyptus globulus wood with oxygen under alkaline conditions was studied. The analysis of oxidation products in the reaction system O(2)/NaOH revealed a predominance of aromatic aldehydes (vanillin and syringic aldehyde) though small amounts of vanillic and syringic acids and acetophenone/phenylacetaldehyde derivativ...
Heavy metal accumulation in plant species indigenous to a contaminated portugue...
Moreira, Helena; Marques, Ana P. G. C.; Rangel, António O. S. S; Castro, P.M.L.Phytoremediation is a promising alternative to conventional soil clean-up methods; however, up to date, there is still not enough information on plant species suitable for application in this field of science. Therefore, plant screening on contaminated sites can lead to the identification of further species of interest. In the present study, pedological and botanical characteristics of an industrialised area kn...
Removal of heavy metals using different polymer matrixes as support for bacteri...
Pires, Carlos; Marques, Ana P.G.C.; Guerreiro, António; Magan, Naresh; Castro, Paula M.L.Great attention is focused on the microbial treatment of metal contaminated environments. Three bacterial strains, 1C2, 1ZP4 and EC30, belonging to genera Cupriavidus, Sphingobacterium and Alcaligenes, respectively, showing high tolerance to Zn and Cd, up to concentrations of 1000 ppm, were isolated from a contaminated area in Northern Portugal. Their contribution to Zn and Cd removal from aqueous streams using...

Assessment of the plant growth promotion abilities of six bacterial isolates us...
Marques, Ana P.G.C.; Pires, Carlos; Moreira, Helena; António O.S.S., Rangel; Castro, Paula M.L.Zea mays, one of the most important cereals worldwide, is a plant not only with food and energy value, but also with phytoremediation potential. The use of plant growth promoting (PGP) rhizobacteria may constitute a biological alternative to increase crop yield and plant resistance to degraded environments. In search for PGP rhizobacteria strains, 6 bacterial isolates were isolated from a metal contaminated sit...
