Use and misuse of FTIR spectroscopy for studying the bio-oxidation of plastics [PDF]
Spectrochimica Acta Part A: Molecular and Biomolecular Spectroscopy, 2021 Due to massive production, inefficient waste collection, and long lives, plastics have become a source of persistent pollution. Biodegradation is explored as an environmentally friendly remediation method for removing plastics from the environment. Microbial and animal biodegradation methods have been reported in the literature for various plastics ...

One Novel two-step Bio-Oxidation Pretreatment of Arsenic-Containing Gold-Bearing Concentrate
International Journal of Electrochemical Science, 2018 A novel process was developed to markedly increase gold cyanidation performance from an arsenic-containing gold-bearing concentrate. Before cyanidation, a two-step bio-oxidation pretreatment was employed to decrease the arsenic content in the residue and

Bio-oxidation of H2S by Sulfolobus metallicus
Biotechnology Letters, 2011 Sulfolobus metallicus is a hyperthermophilic and chemolithoautotrophic archaeon that uses elemental sulfur as an energy source. Its ability to oxidize H(2)S was measured either in the presence or absence of elemental sulphur, showing its ability for using both as an energy source. A biotrickling filter was set up and a biofilm of S.
