Última Petroleum contamination and bioaugmentation in bacterial rhizosphere communities from Avicennia schaueriana BJM Dealtry,Simone; Ghizelini,Angela Michelato; Mendonça-Hagler,Leda C.S.; Chaloub,Ricardo Moreira; Reinert,Fernanda; Campos,Tácio M.P. de; Gomes,Newton C.M.; Smalla,Kornelia. ABSTRACT Anthropogenic activity, such as accidental oil spills, are typical sources of urban mangrove pollution that may affect mangrove bacterial communities as well as their mobile genetic elements. To evaluate remediation strategies, we followed over the time the effects of a petroleum hydrocarbon degrading consortium inoculated on mangrove tree Avicennia schaueriana against artificial petroleum contamination in a phytoremediation greenhouse experiment. Interestingly, despite plant protection due to the inoculation, denaturing gradient gel electrophoresis of the bacterial 16S rRNA gene fragments amplified from the total community DNA indicated that the different treatments did not significantly affect the bacterial community composition. However, while... Tipo: Info:eu-repo/semantics/article Palavras-chave: Phytoremediation; Mangrove; IncP-9 plasmids; Ndo genes.

A mixed culture and a pure bacterial strain (BMV8) were isolated from a bioreactor for thiocyanate treatment. Both cultures removed 5 mM of thiocyanate from the medium in 36 hours. The mixed culture was able to tolerate concentrations up to 60 mM. The efficiency of thiocyanate degradation decreased when the cells were immobilized.

Five strains of Rhodotorula mucilaginosa were tested for the ability to accumulate free and complexed silver ions by metabolism-dependent and -independent processes. The ability to take up Ag+ was observed in both live and dead biomass, whereas silver dicyanide [Ag (CN)2-] uptake was strictly glucose dependent. In contrast to Ag (CN)2-, glucose addition inhibited by 16 to 25% the Ag+ uptake rate of living UFMG - Y02, Y27, and Y35 cells, while strains CBS 316 and UFMG-Y01 showed an improved uptake rate of about 115% and 13%, respectively. The Langmuir sorption model was used to evaluate the silver sorption capability of the R. mucilaginosa strains. The calculated q max value suggested that R. mucilaginosa strains UFMG-Y27 had the highest loading capacity....

Ano: 2002 URL: http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1517-83822002000100013 An optmized protocol for simultaneous extraction of DNA and RNA from soils BJM Costa,Rodrigo; Gomes,Newton C.M.; Milling,Annett; Smalla,Kornelia. In this work we report an optimized protocol for simultaneous extraction of DNA and RNA from soil matrices. Treatment of soil matrices with ethanol followed by bead-beating worked as a successful strategy to lyse the cells without considerable degradation of nucleic acids, resulting in DNA and RNA of good yield and integrity. The reverse transcribed RNA could be amplified with primers targeting a glutamine synthetase (glnA) gene fragment. From both DNA and cDNA, 16S rDNA fragments were amplified and analyzed by Denaturing Gradient Gel Electrophoresis (DGGE). The method was applied to soil and rhizosphere (strawberry and oilseed rape) samples. Two other protocols for the extraction of nucleic acids from soil were applied to the same set of samples in order...
