Nematicidal Bacteria Associated to Pinewood Nematode Produce Extracellular Prot...
Paiva, Gabriel; Proença, Diogo Neves; Francisco, Romeu; Veríssimo, P.; Santos, Susana S.; Fonseca, Luís; Abrantes, I. M. O.; Morais, P. V.Bacteria associated with the nematode Bursaphelenchus xylophilus, a pathogen of trees and the causal agent of pine wilt disease (PWD) may play a role in the disease. In order to evaluate their role (positive or negative to the tree), strains isolated from the track of nematodes from infected Pinus pinaster trees were screened, in vitro, for their nematicidal potential. The bacterial products, from strains more ...
Identification and Characterization of the Transcriptional Regulator ChrB in th...
Branco, Rita; Morais, P. V.Ochrobactrum tritici 5bvl1 is able to resist to high concentrations of chromate through the expression of an inducible chromate-resistant determinant, found in a mobile element (TnOtChr), which carries the genes, chrB, chrA, chrC and chrF. The regulation of chr operon present in TnOtChr, which is controlled by a transcriptional regulator, ChrB, was characterized in the current work. Fusions of chr promoter, or ...
Diversity of chromium-resistant and -reducing bacteria in a chromium-contaminat...
Francisco, R.; Alpoim, M. C.; Morais, P. V.Aims: This study attempts to establish a relationship between the Cr(VI) resistance of the culturable microbial community and the Cr(VI) resistance and Cr(VI)-reducing ability of representative strains of each population, in order to assess whether these are exclusive characteristics of one microbial group or abilities shared among many groups. Methods and Results: A group of 48 Cr(VI)-resistant isolates, with ...
Computer-aided comparison of protein electrophoretic patterns for grouping and ...
Ferreira, A. C.; Morais, P. V.; Gomes, C.; Costa, M. S. daThe microflora of a natural mineral water was studied immediately after bottling (T0) and after 7 d storage (T7) during 6 months, and isolates were clustered by SDS-PAGE of wholecell protein profiles. Isolates from each cluster were further characterized by API 20NE, fatty acid composition and quinone profiles. The numerical analysis of the electrophoregrams of all bacteria isolated from the mineral water forme...
