Bacteria in Nanoparticle Synthesis: Current Status and Future Prospects
International Scholarly Research Notices, Volume 2014, Issue 1, 2014., 2014 Microbial metal reduction can be a strategy for remediation of metal contaminations and wastes. Bacteria are capable of mobilization and immobilization of metals and in some cases, the bacteria which can reduce metal ions show the ability to precipitate metals at nanometer scale. Biosynthesis of nanoparticles (NPs) using bacteria has emerged as rapidly

International Scholarly Research Notices, Volume 2014, Issue 1, 2014., 2014 Core sets of sox genes were detected in several genome sequenced members of the environmental important OM60/NOR5 clade of marine gammaproteobacteria. However, emendation of media with thiosulfate did not result in stimulation of growth in two of these strains and cultures of Congregibacter litoralis DSM 17192T did not oxidize thiosulfate to sulfate in

Practical Considerations and Challenges Involved in Surfactant Enhanced Bioremediation of Oil
BioMed Research International, Volume 2013, Issue 1, 2013., 2013 Surfactant enhanced bioremediation (SEB) of oil is an approach adopted to overcome the bioavailability constraints encountered in biotransformation of nonaqueous phase liquid (NAPL) pollutants. Fuel oils contain n‐alkanes and other aliphatic hydrocarbons, monoaromatics, and polynuclear aromatic hydrocarbons (PAHs).

Exploitation of Bacterial Activities in Mineral Industry and Environmental Preservation: An Overview
Journal of Mining, Volume 2013, Issue 1, 2013., 2013 Since the identification and characterization of iron and sulfur oxidizing bacteria in the 1940s, a rapid progress is being made in minerals engineering based on biological activities. Microorganisms can play a beneficial role in all facets of minerals processing, from mining to waste disposal and management.
