Microorganisms play a significant role in bioremediation of heavy metal contaminated soil and wastewater. In this study, heavy metal resistant fungi and bacteria were isolated from the soil samples of an electroplating industry, and the bioaccumulations of Cr(VI) and Ni(II) by these isolates were characterized to evaluate their applicability for heavy metal(More)
Spotted oligonucleotide microarrays potentially offer a wide scope of applications for microbial ecology, especially as they improve the flexibility of design and the specificity of detection compared to PCR product based microarrays. Sensitivity, however, was expected to be problematic, as studies with the more sensitive PCR-based cDNA microarrays indicate(More)
Strain LB400 is the best-studied polychlorinated biphenyl (PCB) degrader. This organism has previously been allocated in the genus Burkholderia, since its 16S rRNA gene sequence shows 98?6% sequence similarity to the type strains of Burkholderia graminis and Burkholderia terricola. A polyphasic study was undertaken to clarify the actual taxonomic position(More)
Strain LB400T is the best-studied polychlorinated biphenyl (PCB) degrader. This organism has previously been allocated in the genus Burkholderia, since its 16S rRNA gene sequence shows 98.6 % sequence similarity to the type strains of Burkholderia graminis and Burkholderia terricola. A polyphasic study was undertaken to clarify the actual taxonomic position(More)
Simultaneous electricity generation and distillery wastewater (DWW) treatment were accomplished using a thermophilic microbial fuel cell (MFC). The results suggest that thermophilic MFCs, which require less energy for cooling the DWW, can achieve high efficiency for electricity generation and also reduce sulfate along with oxidizing complex organic(More)
Here we present a standard developed by the Genomic Standards Consortium (GSC) for reporting marker gene sequences—the minimum information about a marker gene sequence (MIMARKS). We also introduce a system for describing the environment from which a biological sample originates. The 'environmental packages' apply to any genome sequence of known origin and(More)
The t(7;12)(q36;p13) is one of the recurrent cytogenetic abnormalities that involves the ETV6 gene. It is found in patients suffering with infantile acute myeloid leukemia (AML). We reviewed the cytogenetic and clinical findings of 215 pediatric patients (ages </=17) who were diagnosed with AML to check for abnormalities of 7q and/or 12p. Fluorescence in(More)
Three hydrogen-based membrane biofilm reactors (MBfR) biologically reduced nitrate and perchlorate in a synthetic ion-exchange (IX) brine. Inocula from different natural saline environments were employed to initiate the three MBfRs. Under high-salinity (3%) conditions, bioreduction of nitrate and perchlorate occurred simultaneously, and the three MBfRs from(More)
SET-NUP214 rearrangement is a recently recognized recurrent chromosomal translocation mostly observed in T-ALL. In order to characterize this rare entity, we performed phenotypic and genetic characterization of SET-NUP214 rearrangement through an investigation of a series of 40 consecutive samples of adult T-ALL that was selected among 229 adult ALL cases(More)
The number of functional traits of a wastewater treatment plant (WWTP) microbial community (i.e. functional richness) is thought to be an important determinant of its overall functional performance, but the ecological factors that determine functional richness remain unclear. The number of taxa within a community (i.e. taxonomic richness) is one ecological(More)
