Journal ArticleDOI
Interrelationships among serum thyroxine, triiodothyronine, reverse triiodothyronine, and thyroid-stimulating hormone in iodine-deficient pregnant women and their offspring: effects of iodine supplementation.
J. Enrique Silva,Sérgio Silva +1 more
TL;DR: The present studies were undertaken to analyze the relationships between serum thyroid hormones and TSH concentrations in iodine-deficient pregnantwomen as well as their newborns, and described quantitatively the relationships among iodine intake, thyroid hormones, and T SH.
Journal ArticleDOI
Toxicity of long chain fatty acids towards acetate conversion by Methanosaeta concilii and Methanosarcina mazei.
Sérgio Silva,Andreia Filipa Ferreira Salvador,Ana Júlia Cavaleiro,M. Alcina Pereira,Alfons J. M. Stams,Alfons J. M. Stams,M. Madalena Alves,Diana Z. Sousa,Diana Z. Sousa +8 more
TL;DR: This study indicates that M. concilii and M. mazei tolerate LCFA concentrations similar to those previously described for hydrogenotrophic methanogens, which might contribute to the observed prevalence of Methanosaeta species in anaerobic bioreactors used to treat LCFA‐rich wastewater.
Journal ArticleDOI
Long-term acclimation of anaerobic sludges for high-rate methanogenesis from LCFA
Sérgio Silva,Ana Júlia Cavaleiro,Maria Alcina Pereira,Alfons J. M. Stams,Alfons J. M. Stams,M. Madalena Alves,Diana Z. Sousa,Diana Z. Sousa +7 more
TL;DR: It is shown that long-term sludge acclimation to LCFA is essential for high rate methanogenesis from LCFA, and the endogenous microbiota are not a limiting factor.
Journal ArticleDOI
Insight into the Role of Facultative Bacteria Stimulated by Microaeration in Continuous Bioreactors Converting LCFA to Methane
M. Salomé Duarte,Sérgio Silva,Andreia Filipa Ferreira Salvador,Ana Júlia Cavaleiro,Alfons J. M. Stams,Alfons J. M. Stams,M. Madalena Alves,M. Alcina Pereira +7 more
TL;DR: It is strongly suggested that microaeration stimulates the development of facultative bacteria that are critical for achieving LCFA conversion to methane in continuous bioreactors.
Journal ArticleDOI
Inhibition Studies with 2-Bromoethanesulfonate Reveal a Novel Syntrophic Relationship in Anaerobic Oleate Degradation.
Andreia Filipa Ferreira Salvador,Ana Júlia Cavaleiro,Ana M. S. Paulo,Sérgio Silva,Ana P. Guedes,Maria Alcina Pereira,Alfons J. M. Stams,Alfons J. M. Stams,Diana Z. Sousa,Diana Z. Sousa,M. Madalena Alves +10 more
TL;DR: Two different oleate (C18:1 LCFA)-degrading anaerobic enrichment cultures were developed and it was found that LCFA conversion proceeded faster in the assays where methanogenesis was inhibited, and that it was dependent on the utilization of isethionate.
