Geraniol is an intriguing 10 carbon compound with diverse applications including use as an agent for cancer prevention, fragrance, insect repellent, proposed biofuel etc. We explored and engineered a novel gene expression tool (BBa_K890000) for ''Methanococcus'' with the capability of expressing geraniol synthase from ''Ocimum basilicum'' (BBa_K1138000). We report the biosynthesis of geraniol at over 5% of DCW by transforming the vector into Methanococcus thereby expanding its native isoprenoid pathway. Furthermore we engineered new vectors (BBa_K1138001 & BBa_K1138002) with the potential capability of regulating and quantifying the expression of desired proteins via red fluorescence. This work demonstrates the use of ''Methanococcus'' as a cell factory for chemical production and highlights synthetic biology advancement by engineering new systems over traditional biological systems such as ''Escherichia coli''. | Geraniol is an intriguing 10 carbon compound with diverse applications including use as an agent for cancer prevention, fragrance, insect repellent, proposed biofuel etc. We explored and engineered a novel gene expression tool (BBa_K890000) for ''Methanococcus'' with the capability of expressing geraniol synthase from ''Ocimum basilicum'' (BBa_K1138000).

Welcome to the University of Georgia 2013 iGEM Team Wiki!
Introduction
Over the past couple of decades metabolic engineering and synthetic biology has enabled researchers to develop biological systems for the purpose of producing pharmaceuticals, high value chemicals or other medical devises/ instruments. Most of the synthetic biology work is limited to E. coli. Although E. coli has been exhaustively studied and utilized it does have its drawbacks, like requirement of specific temperatures and growth conditions.
With the intention of expanding synthetic biology beyond traditional approaches and biological platforms we dared to explore/ expand its reach into archaea. The production of high value chemicals in archaea has the following advantages:
In this work we demonstrate the utility of chemicals production in archaea. We targeted the production of Geraniol as:
Abstract
Geraniol production via novel protein expression tools in Methanococcus maripaludis
Geraniol is an intriguing 10 carbon compound with diverse applications including use as an agent for cancer prevention, fragrance, insect repellent, proposed biofuel etc. We explored and engineered a novel gene expression tool (BBa_K890000) for Methanococcus with the capability of expressing geraniol synthase from Ocimum basilicum (BBa_K1138000). We report the biosynthesis of geraniol at over 5% of DCW by transforming the vector into Methanococcus thereby expanding its native isoprenoid pathway. Furthermore we engineered new vectors (BBa_K1138001 & BBa_K1138002) with the potential capability of regulating and quantifying the expression of desired proteins via red fluorescence. This work demonstrates the use of Methanococcus as a cell factory for chemical production and highlights synthetic biology advancement by engineering new systems over traditional biological systems such as Escherichia coli.
