There is growing need to find renewable biologically produced compounds as replacements for petroleum-based fuels. Due to the branched and ringed structures found in their hydrocarbon chain, isoprenoid compounds have the potential to be used as biofuels. The branching improves the cetane number (a measurement of the combustion quality) of fuel mixtures [Murley09]. The C15 isoprenoid compound farnesol is a putative biodiesel with a cetane number that falls withing the expected range for petroleum diesel.
Biodiesel has both disadvantages and advantages compared to petroleum diesel. The disadvantages include biodiesel having poorer cold weather characteristics, producing higher nitrous oxide emissions and a greater ability to oxidize. The advantages include biodiesel being derived from a renewable source, having a lower sulfur content and hence lower oxidized sulfur emissions, increased lubricity and lower carbon monoxide emissions.
Isoprenoid compounds are derived from isopentenyl pyrophosphate (IPP) and dimethyl alleyl diphosphate (DMAPP). These two compounds can be derived from two distinct pathways: the mevalonate pathway I (MVA) and the methylerythritol phosphate pathway I (MEP), also known as deoxyxylulose pathway. The MVA pathway is more energetically favorable than the MEP pathway as it generates protons which can be used to generate ATP, and does not require an input of ATP per se [Murley09].
About this Pathway
Isopentenyl diphosphate (IPP) and dimethylallyl diphosphate (DMAPP) are both derived from either the MVA or MEP pathways [Okada08]. These compounds are precursors to E,E farnesyl diphosphate, an intermediate in the putative biodiesel farnesol biosynthesis [Song06].
A soluble form of phosphatase capable of converting farnesyl diphosphate (FPP) to E,E-farnesol was identified in Saccharomyces cerevisiae [Song06]. The purified FPP phosphatase is a truncated form of alkaline phosphatase [Song06].
FPP can also be converted to farnesane, another valuable diesel fuel, but this does not occur naturally in a biological system.
