Described is a method for generating isoprenol through a biological process. More specifically, described is a method for producing isoprenol from mevalonate.

Disclosed are methods for producing butadiene from one or more of several diverse feedstocks including bioderived feedstocks, renewable feedstocks, petrochemical feedstocks and natural gas.

The invention provides a method for producing an isoprenoid or a precursor thereof by microbial fermentation. Typically, the method involves culturing a recombinant bacterium in the presence of a gaseous substrate whereby the bacterium produces an isoprenoid or a precursor thereof, such as mevalonic acid, isopentenyl pyrophosphate, dimethylallyl pyrophosphate, isoprene, geranyl pyrophosphate, farnesyl pyrophosphate, and/or pinene. The bacterium may comprise one or more exogenous enzymes, such as enzymes in mevalonate, DXS, isoprenoid alcohol, or terpene biosynthesis pathways.

The present disclosure provides methods of synthesizing a cannabinoid, a cannabinoid derivative, a cannabinoid precursor, or a cannabinoid precursor derivative.

Described is a method for the enzymatic production of isoprenol using mevalonate as a substrate and enzymatically converting it by a decarboxylation step into isoprenol as well as the use of an enzyme which is capable of catalyzing the decarboxylation of mevalonate for the production of isoprenol from mevalonate. Furthermore described is the use of mevalonate as a starting material for the production of isoprenol in an enzymatically catalyzed reaction. Also disclosed is a method for the production of isoprene comprising the method for the production of isoprenol using mevalonate as a substrate and enzymatically converting it by a decarboxylation step into isoprenol and further comprising the step of converting the produced isoprenol into isoprene as well as a method for the production of isoamyl alcohol comprising the method for the production of isoprenol using mevalonate as a substrate and enzymatically converting it by a decarboxylation step into isoprenol and further comprising the step of converting the produced isoprenol into isoamyl alcohol.

Disclosed herein are an expression vector capable of expressing myrcene, an Escherichia coli strain transformed with the vector and having improved capability of producing myrcene and a method for producing myrcene and a method for recycling glycerol using the same. In an aspect, the transformed Escherichia coli strain of the present disclosure can produce myrcene with high purity on a large scale using glycerol or glucose as a carbon source. Also, the Escherichia coli strain of the present disclosure is economical and environment-friendly because it can produce high value-added myrcene using waste glycerol as a carbon source. In addition, the strongly volatile myrcene can be produced and isolated at the same time.

Disclosed are methods for producing butadiene from one or more of several diverse feedstocks including bioderived feedstocks, renewable feedstocks, petrochemical feedstocks and natural gas.

This application describes methods, including non-naturally occurring methods, for biosynthesizing unsaturated pentahydrocarbons, such as isoprene and intermediates thereof, via the mevalonate pathway, as well as non-naturally occurring hosts for producing isoprene.
