ReavaliaÃÃo da faixa ideal de pH e da tolerÃncia de juvenis de tilÃpia do nilo, Oreochromis niloticus, Ã acidez elevada da Ãgua de cultivo / Reassessment of the optimum pH range and tolerance for nile tilapiaâs juveniles, Oreochromis niloticus, to the high acidity of the cultivation waterVanessa Tomaz RebouÃas 21 May 2015 (has links)
Conselho Nacional de Desenvolvimento CientÃfico e TecnolÃgico / Dois estudos consecutivos foram realizados para reavaliar a faixa ideal de pH e a tolerÃncia de juvenis de tilÃpia do Nilo, Oreochromis niloticus, à acidez elevada da Ãgua de cultivo, em condiÃÃes eutrÃficas de cultivo. Os pesos iniciais dos animais eram semelhantes em ambas as fases. No primeiro trabalho, foram adotadas quatro condiÃÃes distintas de pH da Ãgua de cultivo: pH = 5,56  1,21 (pH 5); pH = 6,59  0,77 (pH 6); pH = 8,25  0,39 (pH 8); pH = 9,21  0,37 (pH 9), obtidas pelas aplicaÃÃes de soluÃÃes Ãcidas ou alcalinas à Ãgua. Os animais foram mantidos em tanques externos de 250 L por oito semanas. NÃo houve renovaÃÃo da Ãgua de cultivo ao longo de todo o trabalho. Neste trabalho, foram observadas variÃveis de qualidade de Ãgua, solo, zootÃcnicas e metabÃlicas. As maiores concentraÃÃes de nitrogÃnio amoniacal total da Ãgua foram encontradas nos tanques pH 5 e as menores nos tanques pH 8. A concentraÃÃo de gÃs sulfÃdrico na Ãgua foi maior nos tanques pH 5. O peso corporal final, a taxa de crescimento especÃfico e a produtividade do pescado nos tanques pH 5 foram maiores do que o observado nos tanques pH 9. Observou-se maior consumo de oxigÃnio nos respirÃmetros de pH 9. Concluiu-se que a faixa ideal de pH da Ãgua para o cultivo de juvenis de tilÃpia do Nilo, em Ãguas eutrofizadas, vai de 5 a 8. O delineamento experimental do segundo trabalho foi constituÃdo por quatro tratamentos, a saber: Ãguas de cultivo com diferentes valores de pH (pH 4: 4,12  0,84; pH 5: 5,13  0,74; pH 6: 6,14  0,64 e pH 8: 8,06  0,48), com cinco repetiÃÃes cada. NÃo houve troca da Ãgua de cultivo, apenas reposiÃÃo para manter o nÃvel inicial. Durante oito semanas, foram observadas variÃveis de qualidade de Ãgua, solo, zootÃcnicas, metabÃlicas e qualidade de efluentes. Embora a concentraÃÃo de nitrogÃnio amoniacal total (NAT) na Ãgua tenha sido menor nos tanques pH 8, sua concentraÃÃo de amÃnia nÃo-ionizada (NH3) foi maior que nos demais. Ao final, o menor peso corporal dos peixes foi observado nos tanques pH 8. Houve significativa melhora nos resultados de conversÃo alimentar e na taxa de eficiÃncia proteica com a acidificaÃÃo da Ãgua. As concentraÃÃes de NH3 nos efluentes dos tanques acidificados foram reduzidas. Concluiu-se que a acidificaÃÃo gradual da Ãgua de cultivo de juvenis da tilÃpia do Nilo atà pH 4 à benÃfica ao crescimento corporal dos peixes. A avaliaÃÃo de todos os resultados permite inferir que a faixa de pH da Ãgua para cultivo de O. niloticus seja de 4 a 8. / The first experiment aimed to reassess the Nile tilapiaâs optimum range of water pH for culture in eutrophic conditions. The initial weights of the animals were similar in both phases. There were four different conditions of water pH: pH = 5,56  1,21 (pH 5); pH = 6,59  0,77 (pH 6); pH = 8,25  0,39 (pH 8); pH = 9,21  0,37 (pH 9), that were obtained by acidic or alkaline applications upon the rearing waters. The fishes were maintained in twenty outdoor 250-L tanks for eight weeks. No water exchange was performed over the entire study. Variables of water and soil quality, growth performance and metabolism were monitored in the 1st work. The highest concentration of total ammonia nitrogen was observed in the pH 5 tanks and the lowest ones in the pH 8 ones. The hydrogen sulfide concentrations were higher in the pH 5 tanks. Fish final body weight, specific growth rate and yield were higher in the pH 5 tanks than in the pH 9 ones. There was a higher consumption of dissolved oxygen in the pH 9 respirometers than in the other ones. It was concluded that the optimum water pH range for Nile tilapia culture in eutrophic waters is 5 â 8. The second experiment aimed to determine the tolerance of Nile tilapia juveniles to high acidic culture waters and the effects of the culture water acidification upon the tanksâ effluents quality. The experimental design had four treatments, e.g., waters with different pH values (pH 4: 4,12  0,84; pH 5: 5,13  0,74; pH 6: 6,14  0,64 e pH 8: 8,06  0,48), with five replicates each. No water exchange was carried out over the entire study, just water replenishment to maintain the initial level. Variables of water quality, soil, growth performance, metabolism and effluents were observed over eight weeks. In spite of the lower total ammonia nitrogen (TAN) concentration in the pH 8 tanks, their levels of non-ionized ammonia (NH3) were the highest. At the end, the lowest fish body weight was observed in the pH 8 tanks. There was a significant improvement in the feeding conversion ratio and protein efficiency rate by the water acidification. The concentrations of NH3 were reduced in the acidic tank effluents. It was concluded that the gradual water acidification up to pH 4 is good to Nile tilapia juvenilesâ growth performance. The evaluation of all the results shows that the water pH range for cultivation of O. niloticus is 4-8.

Charakterisierung der Mikroorganismen im sauren Grubenwasser des ehemaligen Uranbergwerks KönigsteinZirnstein, Isabel 20 July 2015 (has links) (PDF)
Beim Bergbau werden bestehende Ökosysteme in großem Maße beeinflusst. Im ehemaligen Uranbergwerk Königstein (Sachsen) wurde die Umwelt durch den Einsatz von chemischen Säuren zur Lösung des Urans aus dem Erz (Laugung) in Folge der Verschiebung des pH-Wertes zusätzlich belastet. Durch diesen Prozess entstand eine Umgebung, die einen niedrigen pH-Wert und hohe Konzentrationen an gelösten Schwermetall-Ionen aufweist. Die komplexe mikrobielle Lebensgemeinschaft verschob sich daraufhin, indem sich bevorzugt säuretolerante und Schwermetall-tolerante Mikroorganismen durchsetzten. Diese Mikroorganismen wurden durch die Flutung der unter Tage Schächte im Jahr 2010 in ihrer Zusammensetzung erneut beeinflusst.
In dieser Arbeit wurde die mikrobielle Biozönose nach Flutung der unter Tage Schächte des ehemaligen Uranbergwerkes Königstein charakterisiert und mit den Ergebnissen der mikrobiellen Diversität vor dem Flutungsprozess verglichen. Hierfür kam ein breites Spektrum an Methoden zum Einsatz, das klassische mikrobiologische Methoden und molekularbiologische Techniken umfasste. Die Analysen erfolgten dabei über mehrere Jahre hinweg, um die Variabilität der mikrobiellen Population im Grubenwasser planktonisch und im Biofilm zu erfassen.

Genomic and transcriptomic characterization of novel iron oxidizing bacteria of the genus “Ferrovum“ / Charakterisierung von neuartigen eisenoxidierenden Bakterien der Gattung „Ferrovum” auf Genom- und TranskriptomebeneUllrich, Sophie 30 June 2016 (has links) (PDF)
Acidophilic iron oxidizing bacteria of the betaproteobacterial genus “Ferrovum” are ubiquitously distributed in acid mine drainage (AMD) habitats worldwide. Since their isolation and maintenance in the laboratory has proved to be extremely difficult, members of this genus are not accessible to a “classical” microbiological characterization with exception of the designated type strain “Ferrovum myxofaciens” P3G.
The present study reports the characterization of “Ferrovum” strains at genome and transcriptome level. “Ferrovum” sp. JA12, “Ferrovum” sp. PN-J185 and “F. myxofaciens” Z-31 represent the iron oxidizers of the mixed cultures JA12, PN-J185 and Z-31. The mixed cultures were derived from the mine water treatment plant Tzschelln close to the lignite mining site in Nochten (Lusatia, Germany). The mixed cultures also contain a heterotrophic strain of the genus Acidiphilium. The genome analysis of Acidiphilium sp. JA12-A1, the heterotrophic contamination of the mixed culture JA12, indicates an interspecies carbon and phosphate transfer between Acidiphilium and “Ferrovum” in the mixed culture, and possibly also in their natural habitat. The comparison of the inferred metabolic potentials of four “Ferrovum” strains and the analysis of their phylogenetic relationships suggest the existence of two subgroups within the genus “Ferrovum” (i.e. the operational taxonomic units OTU-1 and OUT-2) harboring characteristic metabolic profiles. OTU-1 includes the “F. myxofaciens” strains P3G and Z-31, which are predicted to be motile and diazotrophic, and to have a higher acid tolerance than OTU-2. The latter includes two closely related proposed species represented by the strains JA12 and PN-J185, which appear to lack the abilities of motility, chemotaxis and molecular nitrogen fixation. Instead, both OTU-2 strains harbor the potential to use urea as alternative nitrogen source to ammonium, and even nitrate in case of the JA12-like species. The analysis of the genome architectures of the four “Ferrovum” strains suggests that horizontal gene transfer and loss of metabolic genes, accompanied by genome reduction, have contributed to the evolution of the OTUs.
A trial transcriptome study of “Ferrovum” sp. JA12 supports the ferrous iron oxidation model inferred from its genome sequence, and reveals the potential relevance of several hypothetical proteins in ferrous iron oxidation. Although the inferred models in “Ferrovum” spp. share common features with the acidophilic iron oxidizers of the Acidithiobacillia, it appears to be more similar to the neutrophilic iron oxidizers Mariprofundus ferrooxydans (“Zetaproteobacteria”) and Sideroxydans lithotrophicus (Betaproteobacteria). These findings suggest a common origin of ferrous iron oxidation in the Beta- and “Zetaproteobacteria”, while the acidophilic lifestyle of “Ferrovum” spp. may have been acquired later, allowing them to also colonize acid mine drainage habitats.
