All of the important bacteria in the biooxidation
are acidophilic and exhibit their performance between 1.2 and 2.3 pH.
Physical and chemical properties of these connections cause low speed of biological degradation and toxic influence that is explained by ability of these hydrocarbons to form films which interfere with the subsequent aerobic biooxidation
. Eventually it leads to violation in operation of biochemical cleaning unit (BCU) in general and to excess of threshold limit value (TLV) of phenols and other harmful compounds in treated waters.
Subjects include static biochemistry, biooxidation
and bioreduction, biodegradation, molecular biology and genetics, microbial ecology, public health and water disinfection, biotechnological processes, waste water and solid waste treatments, and more.
Enzymatic Systems Involved in D-limonene Biooxidation
The microorganisms secrete a sort of natural polymer to facilitate firm adhesion on inert support matrix for biofilm development and biooxidation
mechanism [13, 14].
of arsenopyrite concentrates by Acidithiobaciiius ferrooxidans in shake flasks
Arccon Mining Services (AMS) group were requested to evaluate the technical and economic feasibility of mining the currently defined Silver Hill resource and processing to produce a high-grade saleable precious metal concentrate.In addition, the company continues to assess options for a potential secondary production process to extract values from residual lowgrade pyrite-rich concentrate using biooxidation
.The two possible stages of process development under evaluation are:Stage 1 - Production of high-grade gold and silver concentrate, commencing in Q1 2011.Stage 2 - Processing of lower grade concentrate utilising bacterial oxidation, commencing in Q4 2012.The draft Stage 1 DFS document was completed by AMS in December 2009.
