Bioremediation: Towards a credible technology

Article Abstract:

The technological process of bioremediation harnesses biological systems to clean-up environmental pollutants. Microbial systems are widely used in bioremediation to treat contaminated soils and waters. The focus of bioremediation research has moved away from isolating and constructing superbugs, towards identifying the factors that restrict pollutant transformations and mineralization in natural environments. Bioremediation should be treated as a natural bioengineering process that considers certain interactions, and the quantitative assessment of remedial treatment outcomes is needed to ensure the success of bioremediation.

The phylogenetic position and ultrastructure of the uncultured bacterium Achromatium oxaliferum

Article Abstract:

Molecular biological techniques were adopted to investigate the classification of Achromatium oxaliferum, to avoid the need to study pure cultures of the bacterium. A. oxaliferum cells were obtained from a wetland near the Rydal Water in Cumbria, UK. Comparative sequence analysis indicated that A. oxaliferum has a deep branching lineage within the gamma-subdivision of the Proteobacteria. Findings suggested that A. oxaliferum is related to organisms of the Chromatium assemblage but form a unique lineage within this group of bacteria.

Identification of novel bacterial lineages as active members of microbial populations in a freshwater sediment using a rapid RNA extraction procedure and RT-PCR

Article Abstract:

A study conducted on anoxic sediment samples from a productive freshwater lake using a technique for the rapid extraction of RNA from indigenous bacterial communities resulted in the identification of bacteria lineages related to Pirellula staleyi, a member of Planctomycetales and the OP5 bacterial division. The use of reverse transcriptase PCR revealed evidence of Pirellula-like bacteria that are active in an anoxic environment indicating the widespread occurrence of OP5 members in diverse environments.
