A method for preparing purified yeast is disclosed, where the squalene source is a yeast that hyperproduces squalene. The squalene is useful for pharmaceutical purposes. For instance, it can be used to prepare an oil-in-water emulsion, and the emulsion is particularly suitable for use as an immmological adjuvant.

Described herein are engineered cells including ones having synthetic methylotrophy which include an NADH-dependent enzyme capable of converting G3P to 3PG (e.g., B. methanolicus gapN) and/or fructose-1,6-bisphosphatase, along with hexulose-6-phosphate synthase, 6-phospho-3-hexuloisomerase, a phosphoketolase, or a combination thereof. Engineered cells of the disclosure beneficially maintain adequate pool sizes of phosphorylated C3 and/or C4 compounds, and/or provide increased levels of NADPH. As such, the modifications allow for the generation of C6 compounds from C1 (e.g., a methanol feedstod) and C5 compounds, the regeneration of C5 compounds from C6 compounds by carbon rearrangement, and an improved balance between regeneration of C5 compounds and lower glycolysis. In turn, this allows the engineered microorganism to generate sufficient quantities of metabolic precursors (e.g., acetyl-CoA) which can be used in a bioproduct pathway, and the engineered cells can include further modifications to those pathway enzymes allowing for production of a desired bioproduct.

The invention relates to methods and bacterial strains for making terpene and terpenoid products, the bacterial strains having improved carbon pull through the MEP pathway and to a downstream recombinant synthesis pathway.

The present disclosure generally relates to modified microorganisms comprising an optimized system for oligosaccharide utilization comprising one or more polynucleotides coding for one or more energy independent oligosaccharide transporters for transporting an oligosaccharide into the microorganism, one or more polynucleotides coding for enzymes that catalyze the conversion of the oligosaccharide into at least one phosphorylated saccharide, and one or more polynucleotides coding for enzymes that catalyze the conversion of the phosphorylated saccharide into an isomer of the phosphorylated saccharide that is utilized in one or more enzymatic pathways in the microorganism for the production of an organic molecule such as acetic acid, acrylic acid, 3-hydroxypropionic acid, lactic acid, etc. The present disclosure also generally relates to methods of using the optimized system for oligosaccharide utilization.

Described herein is a method of producing a drimane sesquiterpene, such as an albicanol compound and/or derivatives thereof, by contacting at least one polypeptide with farnesyl diphosphate (FPP) with a polypeptide of the Haloacid dehalogenase-like (HAD-like) hydrolase superfamily as obtainable from plants of the genus Dryopteris, in particular of the species Dryopteris fragrans. The method may be performed in vitro or in vivo. Also described herein are amino acid sequences of polypeptides useful in the methods and nucleic acids encoding the polypeptides described. Also described herein are host cells or organisms genetically modified to express the polypeptides and useful to produce a drimane sesquiterpene such as an albicanol compound.
