Project Details


This relates to a method of binding cells on a bulk natural substrate using a biopolymer. This facilitates delivery of microbial loads to contaminated sites. Cells have mercury volatilising capability, and a coconut mat has been produced which captures the mercury gas. ·

OCI Ref 2017001 :.. Methyl Mercury Filter- Innovation disclosure form received by OCI 21 Dec 2016.

Using synthetic biology, microbial cells have been genetically modified such that a fusion protein is produced. The active part of the enzyme de-methylates highly toxic methyl mercury compounds, and the enzyme also has an additional component allowing for binding to a silica substrate. This.allows for an immobilized enzyme to be produced and bound to silica particles for the purposes of creating a fixed bed catalytic reactor that can be deployed as a filter for methyl mercury compounds.
