Microbial Diversity and Zinc Toxicity to Pseudomonas sp. from Coeur d' Alene River Sediment: Author: Barua, Sutapa; Date: 2007-08-15; Program: Chemical Engineering; Abstract: Coeur d'Alene River (CDAR) in northern Idaho is one of the metal contaminated rivers in US. The sediments of the river are enriched with As, Cd, Cu, Pb, and Zn which are toxic metals to humans and animals. It is hypothesized that microorganisms living in this river sediment can remove the metals and thus detoxify their environment. The objective of this work is to investigate the microbial communities existing in CDAR sediment using 16S ribosomal RNA (rRNA) gene sequencing and 16S rRNA gene microarray (PhyloChip) analysis. According to our phylogenetic analysis, the CDAR clones fell into 13 di...; Download File | View full details
