The evolution of a conjugative plasmid and its ability to increase bacterial fi...
Dionisio, F.; Conceição, I.C.; Marques, A.C.R.; Fernandes, L.; Gordo, I.Conjugative plasmids are extra-chromosomal DNA elements that are capable of horizontal transmission and are found in many natural isolated bacteria. Although plasmids may carry beneficial genes to their bacterial host, they may also cause a fitness cost. In this work, we studied the evolution of the R1 plasmid and we found that, in spite of the R1 plasmid conferring an initial cost to its host, after 420 genera...
Soy protein concentrate as a protein source for Senegalese sole (Solea senegale...
Aragão, C.; Conceição, L. E. C.; Dias, J.; Marques, A. C.; Gomes, E.; Dinis, Maria TeresaThe objective of this workwas to evaluate the effect of a dietary amino acid imbalance, originating from the use of a soy protein concentrate (SPC) as the major protein source, on the growth performance and amino acid metabolism of Senegalese sole (Solea senegalensis) postlarvae. Senegalese sole (85.6724.6mg wet weight) were fed one of two experimental diets: one based on fish meal (FM) and another based on SPC...
