Humic substances as electron acceptors for microbial respiration
Article Abstract:
Geobacter metallireducens and Shewanella alga use humic substances to reduce Fe(III) oxides and act as electron acceptors during the anaerobic oxidation of organic compounds and hydrogen. This electron transport produces energy for development. Humic substances help in electron transfer between the humic-reducing microorganisms and the Fe(III) oxide. This finding has significant implications regarding the mechanisms for microbial oxidization of natural and contaminant organics in anaerobic soils and sediments.

Anoxic bioremediation of hydrocarbons
Article Abstract:
Research shows that perchlorate-reducing microorganisms produce extracellular oxygen during chlorite dismutation. A perchlorate-reducing anaerobic bacteria named strain CKB has been identified in waste sludge. Evidence suggests that hydrocarbons can be degraded by CKB in anaerobic conditions using chlorite at ninety micrograms per litre.
