Synthetic Oil YeastCreation of the Synthetic Oil Yeast: A major step forward in fatty acid production

In an article published in the prestigious journal Cell, Biopetrolia-affiliated researchers were able to reprogram the yeast S. cerevisiae from traditional alcoholic fermentation to lipogenesis. In simpler terms, transform a yeast that was used for alcohol production into a yeast that produces fatty acids instead.

Through dozens of modifications to its metabolism, yeast cells rewired this way produce fatty acids because they need them to survive and grow. This strategy allowed 3production of more than 30g/L of free fatty acids, a significant improvement over previous attempts.

FEMSYRNew synthetic biology tools by Biopetrolia and collaborators

The use of 2A “self-cleaving” peptides can greatly simplify construction of complex pathways in yeast. However, not all 2A peptides are created equal. In an article published by researchers from Biopetrolia, Chalmers University and UNSEP, detailed characterization of multiple 2A peptide sequences to determine suitability for metabolic engineering applications in yeast was undertaken. The characterization pointed at particularly-efficient peptides, providing a new synthetic biology tool to allow rapid construction of metabolic pathways in yeast.

Third granted patent for microbial production of fatty acid-derived products

Biopetrolia has received a notice of allowance from the USPTO for a patent divisional application related to engineering hydrocarbon metabolism in yeast. The original patent, granted in 2017, claims yeast strains with modifications that allow increased production of hydrocarbons (used primarily as biofuels). The newly granted divisional patent claims yeast strains with modifications to allow for increased production of fatty acids, fatty alcohols and fatty aldehydes, which that can be used in a wide variety of industrial applications.

PNASTaking a minimalist approach to fatty acid production

In an article published in PNAS, Biopetrolia-affiliated researchers generated a yeast platform strain with a simplified lipid metabolism. This strain allowed for a study of the fatty acid dynamics in lipid metabolism, which in turn enabled increased production of fatty acids through a redirected fatty acid metabolism pathway. The study provides new insights into the future development of lipid-related cell factories.

X10967176Biopetrolia-affiliated researchers make fatty alcohol secretion possible in yeast

Biopetrolia-affiliated researchers at Chalmers reported on the engineering of yeast for production of fatty alcohols, recently published in the journal Metabolic Engineering. The production was increased through facilitating fatty alcohol secretion using heterologous transporters.

Secretion of fatty acid-derived products is an important stepping stone towards high level and robust production of these in yeast. By secreting the products, downstream purification and processing becomes simpler and more efficient. At the same time, as the product does not accumulate in the cell, cell fitness and overall production capacities could be significantly increased.

Medium Chain HydrocarbonsBiopetrolia-affiliated researchers publish a paper on production of drop-in molecules for gasoline and jet fuel in yeast

In a recent publication in the journal Metabolic Engineering, Biopetrolia-affiliated researchers at Chalmers reported on the engineering of yeast for production of medium chain aliphatic hydrocarbons. Medium chain hydrocarbons such as alkanes and alkenes are the main constituents of gasoline and jet fuels and are therefore attractive drop-in fuel for these purposes.

The process includes engineering of the yeast fatty acid synthesis machinery, so that the right fatty acid length is produced, followed by conversion of this fatty acid to an alkane or alkene form.

nature-communicationsProduction of the antiviral drug Docosanol through yeast fermentation

Chalmers and Biopetrolia researchers successfully engineered yeast cells for production of Docosanol with increased efficiency and selectivity, as reported by the paper in Nature Communications. Docosanol is a very long chain fatty alcohol mostly used as an emollient, emulsifier, and thickener in cosmetics. It is also commercialized as an FDA-approved antiviral agent for treatment of herpes simplex virus symptoms.
For producing docosanol, yeast cells were first engineered to produce very long chain fatty acids, which are present in only very low levels in the native cells. Subsequent engineering led to the conversion of said fatty acids into their fatty alcohol form in a very specific way free of contaminants from similar molecules.

Research by Biopetrolia and Chalmers researchers has recently been featured as the cover story in Natural Chemical Biology. The research involves modification of Fatty Acid Synthase, an enzyme that normally synthesizes long chain fatty acids. In this work the enzyme was re-engineered to produce short and medium fatty acids and methyl ketones, important compounds in the chemicals and fragrance industries. When combined with further manipulation of the yeast metabolism, a record level of short and medium chain fatty acids was achieved.

nature-communicationsYeast engineered for high-titer fatty acid production by Biopetrolia researchers

Biopetrolia – affiliated researchers have published a paper in Nature Communications on engineering yeast for high-level production of fatty acids and derived products. The engineered strains are so far the highest producer microorganism for fatty acids, reaching levels of up to 10.4 g/L. Using the same strategy, the authors were able to further engineer these cells to directly produce alkanes (molecular components of gasoline and diesel) and fatty alcohols valuable as formulation ingredients for personal care products.

The paper shows application of some of Biopetrolia’s patented principles on engineering yeast metabolism for efficient production of sustainable chemicals and brings the technology one step closer to a competitive leadership in industry.

sb-2015-00161y_0008Biopetrolia researchers demonstrate improvement of platform strains through the use of biosensors

Biopetrolia researchers have published a paper in ACS Synthetic Biology on the development and utilization of new yeast biosensor for simultaneously sensing and controlling yeast metabolism. The aim of this study was to demonstrate one case where yeast cells can use biosensors to control and improve production of a given chemical. 

In this paper, the researchers engineered yeast cells to implement a genetic circuit capable of sensing one internal molecule and convert it into a precursor for plastic polymers. More specifically, the levels of the precursor metabolite malonyl-CoA are sensed in the cell by the genetic circuit, which activates production of enzymes that will then convert it to the final product 3-hydroxypropionic acid. The use of this system allows precise control of the metabolic pathway and increased production by 10-fold.

The paper displays some of the technology developed so far at Chalmers and Biopetrolia and exemplifies how it can be used in different combinations for varied applications.

BIT_leftFirst-time report of alkane production in yeast

In a recent publication, Chalmers and Biopetrolia-affiliated researchers demonstrate for the first time the production of gasoline and diesel constituents using the yeast Saccharomyces cerevisiae.

Until now, production of biofuels in yeast was limited to low energy molecules, such as ethanol. These are only compatible with modern transportation fuels in a low percentage. Higher energy molecules, such as alkanes (the main constituent of modern fuels such as diesel and gasoline) are therefore important to produce in a sustainable way. In this publication, researchers show it is possible to produce these same alkanes from sugar in a renewable way. This discovery opens up a possible reality where a renewable biofuel produced using yeast cells is totally compatible with modern transportation fuels.
