Background. A previously discovered mutant of Saccharomyces cerevisiae alcohol dehydrogenase 1 (Adh1p) was shown to enable a unique NADH-dependent reduction of 5-hydroxymethylfurfural (HMF), a well-known inhibitor of yeast fermentation. In the present study, site-directed mutagenesis of both native and mutated ADH1 genes was performed in order to identify the key amino acids involved in this substrate shift, resulting in Adh1p-variants with different substrate specificities.. Results. In vitro activities of the Adh1p-variants using two furaldehydes, HMF and furfural, revealed that HMF reduction ability could be acquired after a single amino acid substitution (Y295C). The highest activity, however, was reached with the double mutation S110P Y295C. Kinetic characterization with both aldehydes and the in vivo primary substrate acetaldehyde also enabled to correlate the alterations in substrate affinity with the different amino acid substitutions.. Conclusions. We demonstrated the key role of Y295C ...

The present invention concerns the synthesis of 5-methyl-2-furoic acid, including ester, amide, and thioester derivatives of such from 5-(chloromethyl)-2-furaldehyde (CMF). The molecules so prepared are useful as intermediates for pharmaceutical, food, and fragrance molecules; as well as fuel or fuel additives.

Furfural is a major growth inhibitor in lignocellulosic hydrolysates and improving furfural tolerance of microorganisms is critical for rapid and efficient fermentation of lignocellulosic biomass. In this study, we used the RNAi-Assisted Genome Evolution (RAGE) method to select for furfural resistant mutants of Saccharomyces cerevisiae, and identified a new determinant of furfural tolerance. By using a genome-wide RNAi (RNA-interference) screen in S. cerevisiae for genes involved in furfural tolerance, we identified SIZ1, a gene encoding an E3 SUMO-protein ligase. Disruption of SIZ1 gene function by knockdown or deletion conferred significantly higher furfural tolerance compared to other previously reported metabolic engineering strategies in S. cerevisiae. This improved furfural tolerance of siz1Δ cells is accompanied by rapid furfural reduction to furfuryl alcohol and leads to higher ethanol productivity in the presence of furfural. In addition, the siz1Δ mutant also exhibited tolerance towards

The heterogeneous catalytic partial oxidation of alcohols and aldehydes in the liquid phase usually needs the addition of a homogeneous base, which in turn makes the products’ recovery cumbersome, and can further induce undesired side reactions. In the present work, we propose the use of novel catalysts based on metallic Au, Pd and bimetallic AuPd nanoparticles embedded in a titanosilicate matrix. The as-prepared catalysts showed good efficiency in the base-free partial oxidation of furfural and 5-hydroxymethylfurfural. Au4Pd1@SiTi catalyst showed high selectivity (78%) to monoacids (namely, 5-formyl-2-furancarboxylic acid and 5-hydroxymethyl-2-furancarboxylic acid) at 50% 5-hydroxymethylfurfural (HMF) conversion. The selectivity even reached 83% in the case of furfural oxidation to furoic acid (at 50% furfural conversion). The performances of the catalysts strongly depended on the Au–Pd ratio, with an optimal value of 4:1. The pH of the solution was always below 3.5 and no leaching of

An organic compound known as 5-hydroxymethylfurfural (HMF) is formed from reducing sugars in honey and various processed foods in acidic environments when they are heated through the Maillard reaction. In addition to processing, storage conditions affect the formation HMF, and HMF has become a suitable indicator of honey quality. HMF is easily absorbed from food through the gastrointestinal tract and, upon being metabolized into different derivatives, is excreted via urine. In addition to exerting detrimental effects (mutagenic, genotoxic, organotoxic and enzyme inhibitory), HMF, which is converted to a non-excretable, genotoxic compound called 5-sulfoxymethylfurfural, is beneficial to human health by providing antioxidative, anti-allergic, anti-inflammatory, anti-hypoxic, anti-sickling, and anti-hyperuricemic effects. Therefore, HMF is a neo-forming contaminant that draws great attention from scientists. This review compiles updated information regarding HMF formation, detection procedures, mitigation

High concentrations of 5-hydroxymethylfurfural (HMF) in honey provide an indication of overheating under inappropriate storage conditions or aging. Conventional methods for determining HMF are cumbersome and require expensive equipment or hazardous reagents. Hence the aim of this study was to propose a new analytical tool for HMF determination in honey, using a low cost acoustic wave sensor. Volatile organic compounds (VOCs) of honey samples were extracted, using the solid phase microextraction (SPME) technique, and HMF was quantified, using a piezoelectric quartz crystal with gold electrodes coated with a layer of decamolybdodivanado phosphoric acid, sensitive to HMF. The reliability of the proposed method was confirmed after comparing the results of HMF quantification with those obtained by the conventional spectrophotometric White method, and no statistical differences were found (alpha = 0.05).

article{e5e225c1-5da3-43d2-a4fa-77b2ea1a9abb, abstract = {Treatment with alkali, particularly overliming, has been widely used as a method for the detoxification of lignocellulose hydrolysates prior to ethanolic fermentation. However, the mechanisms behind the detoxification effect and the influence of the choice of cation have not been well understood. In this study, a dilute acid hydrolysate of spruce and an inhibitor cocktail consisting of six known inhibitors were used to investigate different alkali detoxification methods. The various treatments included the addition of calcium hydroxide, sodium hydroxide, potassium hydroxide, and ammonia to pH 10.0 and subsequent adjustment of the pH to 5.5 with either sulfuric or hydrochloric acid as well as treatment with the corresponding amounts of calcium, sodium, and potassium as sulfate or chloride salts at pH 5.5. An RP-HPLC method was developed for the separation of 18 different inhibitors in the hydrolysate, including furaldehydes and phenolics. ...

Hot pressurized liquid extraction has been used to obtain polyphenols; however, its operating conditions can generate hydroxymethylfurfural, a potential human carcinogen. The addition of ethanol can reduce process temperatures and retain extraction efficiencies, but the ethanol may reduce the recovery of polyphenols in the subsequent purification stage, affecting the antioxidant properties of the extracts. This study evaluates a combined hot pressurized liquid extraction-resin purification process to obtain polyphenol extracts from spent ground coffee reduced in hydroxymethylfurfural. A multifactorial design was developed to determine the combined effect of the extraction (ethanol content: 0-16% and temperature: 60-90 °C) and purification (ethanol: 60-80%) conditions on some chemical properties of the extracts. The highest recovery of polyphenols (~8 mg GAE/g dry coffee solids) and reduction of hydroxymethylfurfural (95%) were obtained at 90 °C and 16% of ethanol during extraction and 80% of ethanol

During pretreatment of lignocellulose raw material, compounds that severely inhibit microbial activity including Saccharomyces cerevisiae strains are released [1]. These compounds, which include furaldehydes and weak organic acids, inhibit yeast metabolism and affect yeast viability and, as a consequence, reduces the overall productivity of an ethanol production process [2]. Elucidation of the molecular mechanisms behind inhibition can suggest new strategies to prevent the inhibitory effect. In the present study, the possible effect on the plasma membrane in S. cerevisiae is studied as a response to inhibitors present in lignocellulose raw material. A comparative lipidomic profiling will be carried out on S. cerevisiae cultured in the absence and presence of lignocellulose inhibitors. LC-CAD and GC-MS will be used to extensively characterize the composition of the plasma membrane. Changes in membrane composition will be correlated with the presence of specific inhibitors.

Background: Lignocellulosic substrates and pulping process streams are of increasing relevance to biorefineries for second generation biofuels and biochemical production. They are known to be rich in sugars and inhibitors such as phenolic compounds, organic acids and furaldehydes. Phenolic compounds are a group of aromatic compounds known to be inhibitory to fermentative organisms. It is known that inhibition of Sacchromyces cerevisiae varies among phenolic compounds and the yeast is capable of in situ catabolic conversion and metabolism of some phenolic compounds. In an approach to engineer a S. cerevisiae strain with higher tolerance to phenolic inhibitors, we selectively investigated the metabolic conversion and physiological effects of coniferyl aldehyde, ferulic acid, and p-coumaric acid in Saccharomyces cerevisiae. Aerobic batch cultivations were separately performed with each of the three phenolic compounds. Conversion of each of the phenolic compounds was observed on time-based ...

Development of industrial yeast strains with high tolerance towards the inhibitors released during biomass pretreatment is critical for bioethanol production. Combining this trait with increased thermotolerance would result in a more efficient production via Simultaneous Saccharification and Fermentation (SSF) as well as reduced cooling costs. The aim of the present work was to develop a yeast strain combining these traits. Using a long-term adaptation strategy a stable Saccharomyces cerevisiae isolate (ISO12) was evolved from the industrial strain Ethanol Red (ER). ISO12, contrary to the parental strain, is capable of growing and fermenting the liquid fraction of non-detoxified spruce hydrolysate at 39°C with an ethanol yield of 0.38 g ethanol . g hexoses-1. In contrast with previous studies, the superior phenotype of ISO12 does not rely on higher reductase activities for furaldehyde inhibitor conversion, but rather on a higher thermotolerance. ISO12 shows a higher capacity to ferment hydrolysate at

Aldehydes are readily found in the environment; formed from the burning of organic matter such as tobacco and lipids such as gasoline, oil, and fats as well as byproducts in the ozonation of water. Exposure to aldehydes is known to have adverse health effects. Aldehydes have also been associated with disease such as breast cancer, lung cancer, and liver disease. The analysis of trace levels of aldehydes in biological matrices is difficult because they are highly reactive, water soluble and volatile. During the summer of 2010, we developed an accurate, solvent free analytical method to detect trace levels (parts-per-trillion) of ten aldehyes in human blood, plasma, and serum: acetaldehyde, acrolein, butanal, isopentanal, pentanal, hexanal, heptanal, furaldehyde, benzaldehyde, and o-tolualdehyde. Analytes were extracted from the headspace of the biological sample, desorbed into a heat injector and resolved using a gas chromatograph. A high-resolution mass spectrometer detected analytes with multiple ion

Abstract Background Compounds such as furfural and 5-hydroxymethylfurfural (5-HMF) are generated through the dehydration of xylose and glucose, respectively, during dilute-acid pretreatment of lignocellulosic biomass and are also potent microbial growth and fermentation inhibitors. The enzymatic reduction of these furan aldehydes to their corresponding, and less toxic, alcohols is an engineering approach that has been successfully implemented in both Saccharomyces cerevisiae and ethanologenic Escherichia coli, but has not yet been investigated in thermophiles relevant to biofuel production through consolidated bioprocessing (CBP). Developing CBP-relevant biocatalysts that are either naturally resistant to such inhibitors, or are amenable to engineered resistance, is therefore, an important component in making biofuels production from lignocellulosic biomass feasible. Results A butanol dehydrogenase encoding gene from Thermoanaerobacter pseudethanolicus 39E (Teth39_1597), previously shown to have ...

Many aldehydes such as furfural are present in high quantities in lignocellulose lysates and are fermentation inhibitors that make biofuel production from this abundant carbon source extremely challenging. Cbei_3974 has recently been identified as an aldo-keto reductase responsible for partial furfural resistance in Clostridium beijerinkii. Rational engineering of this enzyme could enhance the furfural tolerance of this organism thereby improving biofuel yields. We report an extensive characterization of Cbei_3974 and a single crystal X-ray structure of Cbei_3974 in complex with NADPH at a resolution of 1.75 Å. Docking studies identified residues involved in substrate binding and an activity screen revealed the substrate tolerance of the enzyme. Hydride transfer, which is partially rate limiting under physiological conditions, occurs from the pro-R hydrogen of NADPH. Enzyme isotope labeling revealed a temperature-independent enzyme isotope effect of unity, indicating that the enzyme does not ...

A gold catalyst can help convert biomass into methyl esters for use as an alternative chemical industry feedstock to compliment or even displace petroleum-derived compounds. Claus Christensen and colleagues in the Center for Sustainable & Green Chemistry at the Technical University of Denmark, in Lyngby, have developed a selective gold-catalyst for the oxidation of furfural and hydroxymethylfurfural into their respective methyl esters. The researchers used sodium methoxide in methanol solvent, an oxygen atmosphere, and gold deposited on titania nanoparticles to efficiently convert the hydroxyl and/or aldehyde groups of the starting materials to the end product. Methyl furoate formed from furfural is useful for flavor and fragrance applications and potentially as an industrial solvent. Furandimethylcarboxylate derived from hydroxymethylfurfural is a monomer that can replace terephthalic acid in plastics, the researchers say.. ...

Alternatives to petroleum-based chemicals are highly sought-after for ongoing efforts to reduce the damaging effects of human activity on the environment. Copper radical oxidases from Auxiliary Activity Family 5/Subfamily 2 (AA5_2) are attractive biocatalysts because they oxidize primary alcohols in a chemoselective manner without complex organic cofactors. However, despite numerous studies on canonical galactose oxidases (GalOx, EC 1.1.3.9) and engineered variants, and the recent discovery of a Colletotrichum graminicola copper radical alcohol oxidase (AlcOx, EC 1.1.3.13), the catalytic potentials of very few AA5_2 members have been characterized. Guided by the sequence similarity network and phylogenetic analyses, we targeted a distinct paralog from the fungus C. graminicola as a representative member of a large uncharacterized subgroup of AA5_2. Through recombinant production and detailed kinetic analysis, we demonstrated that this enzyme is weakly active toward carbohydrates but efficiently

Gas-phase hydrogenation of furfural to tetrahydrofurfuryl alcohol is catalyzed by Ni/SiO2 with ,4 nm Ni particle size, which is prepared by the reduction of supported nickel nitrate. The maximum yield is 94 %. The conversion of furfural to the furfuryl alcohol intermediate is less structure-sensitive. The subsequent step in which furfuryl alcohol is converted to tetrahydrofurfuryl alcohol is inhibited by the presence of furfural because furfural is more strongly adsorbed onto the catalyst surface than furfuryl alcohol. This step is strongly structure-sensitive and smaller turnover frequency (TOF) values are observed over Ni/SiO2 catalysts with a larger particle size. ...

The main purpose of this study was to investigate the impact of furfural on mixed cultures during fermentative hydrogen production from lignocellulosic biomass. Small batch studies using synthetic lignocellulosic hydrolysate grown on mesophilic mixed cultures, revealed a threshold furfural concentration of greater than 1 g/L with enhancement to the yields (from the control) observed at 0.5 g/L furfural (at initial substrate-to-biomass (S°/X°) ratios of 0.5 and 1 gCOD/gVSS) and at both 0.5 g/L and 1 g/L furfural (at S°/X° of 2 and 4 gCOD/gVSS). This study was scaled-up from 200 mL to 11 L working volume batches, using half the substrate concentration of the small batch studies, at an S°/X° of 4 gCOD/gVSS in order to determine the Monod microbial kinetics of mixed cultures in the presence of furfural at both mesophilic and thermophilic temperatures. A 45 % enhancement at 1 g/L furfural was observed in the mesophilic experiment but a 50 % reduction at the same furfural concentration was observed at

The present study was done to optimize the power ultrasound processing for maximizing diastase activity of and minimizing hydroxymethylfurfural (HMF) content in honey using response surface methodology. Experimental design with treatment time (1-15 min), amplitude (20-100 %) and volume (40-80 mL) as independent variables under controlled temperature conditions was studied and it was concluded that treatment time of 8 min, amplitude of 60 % and volume of 60 mL give optimal diastase activity and HMF content, i.e. 32.07 Schade units and 30.14 mg/kg, respectively. Further thermal profile analyses were done with initial heating temperatures of 65, 75, 85 and 95 ºC until temperature of honey reached up to 65 ºC followed by holding time of 25 min at 65 ºC, and the results were compared with thermal profile of honey treated with optimized power ultrasound.

We have developed a one-pot saccharification strategy that uses inorganic salt solutions and less water and combines the lignocellulose pretreatment and saccharification steps under mild conditions (85 C, 1 h). At sufficiently low water content, the solution is called molten salt hydrate. This process intensification also uses less energy and can produce up to 95% theoretical glucose and xylose, from multiple lignocellulose sources. This process produces sugars at faster rates owing to exfoliation of the biopolymers, the greater accessibility of the porous biomass fibers by the salt solution, and the very effective proton-catalyzed de-etherification of the C-O-C bonds. Subsequent biphasic integration of the saccharification with dehydration enables reactive extraction of products such as 5-hydroxymethylfurfural (HMF) and furfural from the homogeneous hydrolysates. The cooperativity of Lewis and Brønsted acidity and high viscosity of the salt solution result in higher HMF and furfural yields ...

The development of inhibitor tolerant ethanologenic yeasts is one of the important challenges for a successful bioethanol production process from lignocellulose. Furthermore, an efficient microorganism for bioethanol production has to be able to ferment xylose together with glucose since xylose represents a large fraction in the lignocellulosic biomass. Weak acids and phenolic compounds are some of the prevalent inhibitors generated during pretreatment of lignocellulose and they will be present in the fermentation broth stressing the yeast affecting the fermentation performance. Although some studies on the effect of organic acids on fermenting microorganisms have been published, there is a lack of knowledge on the effect of phenolic compounds on yeast and more concretely about the effect on the xylose fermentation performance. In this study, the effect of acetic acid and vanillin on yeast growth on glucose and xylose will be elucidated using synthetic media mimicking lignocellulosic hydrolysates. It is

Utilization of alternative materials other than pure sugars may introduce unintended negative effects. For example, the inherent phosphorus in potato starch can prolong the growth cycle of A. terreus and hence decrease the yield of the IA (Petruccioli et al., 1999). Similarly, the inherent nitrogen in plant-derived hydrolysate may affect the IA production by low nitrogen-demanding U. maydis (Klement et al., 2012). For lignocellulosic materials, cellulose and hemicellulose are usually degraded to fermentable sugars by pretreating and hydrolyzing before further conversion into the IA. Nevertheless, the pretreatment may produce multiple inhibitors such as formic acid, acetic acid, furfural, hydroxymethylfurfural (HMF), and levulinic acid, which influence to some extent the microbial growth and IA production. Moreover, enzyme (Krull et al., 2017a) and buffer solution (Yang, 2018) used in the hydrolysis, manganese and other metal ions, as well as certain salts in the hydrolysate could also bring ...

The effect of temperature on the phenol content, flavonoids content, hydroxymethylfurfural (HMF) and antioxidant activity (DPPH and ABTS) in five artisanal honeys of different floral origins was investigated. The total phenol and total flavonoid content showed either linear or quadratic curves (P , 0.05) for heat treatment according to the origin of the honey. For HMF, all of the honeys displayed linear behavior with the heat treatments. All of the honeys had linear responses to temperature (P , 0.05) and antioxidant activity as measured by DPPH. The antioxidant activity measured as the ABTS showed either a linear or quadratic (P , 0.05) curve response depending on the floral origin. The profile of the correlation coefficients between the bioactive compounds (phenols, flavonoids and HMF) and antioxidant activity (DPPH and ABTS) was different for each type of honey. It is possible to enhance the antioxidant activity of artisanal honeys with a specific heat treatment ...

Chemicals based on renewable resources are much desired in view of the dwindling supply of fossil fuels and the climatic problems caused by the accompanying rise in CO2 production. Polymers are among the highest volume chemical materials and thus their production from renewable resources would be highly rewarding. Two different strategies can be followed. On the one hand one can aim to develop new synthetic strategies towards existing monomers, such as adipic acid, caprolactam, or acrylic acid.[1] In the lecture, examples will be given how these monomers can be made from the platform chemicals 5-hydroxymethylfurfural (HMF) and levulinic acid (LA). Another and perhaps long term more rewarding strategy is based on the use of novel monomers that can be prepared in a limited number of steps from renewable resources. One compound that can be obtained in a rather straightforward manner from lignocellulose is levulinic acid (LA). LA can be easily cyclized to α-Angelica lactone (AL) in excellent yield ...

Background: The yeast Saccharomyces cerevisiae plays an essential role in the fermentation of lignocellulosic hydrolysates. Weak organic acids in lignocellulosic hydrolysate can hamper the use of this renewable resource for fuel and chemical production. Plasma-membrane remodeling has recently been found to be involved in acquiring tolerance to organic acids, but the mechanisms responsible remain largely unknown. Therefore, it is essential to understand the underlying mechanisms of acid tolerance of S. cerevisiae for developing robust industrial strains. Results: We have performed a comparative analysis of lipids and fatty acids in S. cerevisiae grown in the presence of four different weak acids. The general response of the yeast to acid stress was found to be the accumulation of triacylglycerols and the degradation of steryl esters. In addition, a decrease in phosphatidic acid, phosphatidylcholine, phosphatidylserine and phosphatidylethanolamine, and an increase in phosphatidylinositol were observed.

Fibreboards are made of lignocellulosic fibres and synthetic adhesive which connect them. These synthetic adhesives, while relatively low-cost, are usually non-biodegradable and may cause health and environmental issues. Therefore, in recent years, there has been an increased demand for replacing these adhesives with bio-derived adhesives. The present study aims to develop fibreboards from chemo-thermomechanical pulp and a furanic resin based on prepolymers of furfuryl alcohol via wet-processing. To improve the bonding properties, maleic acid, aluminium sulphate, and cellulose nanocrystals (CNCs) were added. The resulting fibreboards were evaluated for their structural features and mechanical properties. The bending strength was improved when CNCs were added into the fibres suspension, and the morphology indicated a more compact structure. The combination of the CTMP with CNC and Biorez resulted in the same mechanical behaviours as those noted for CTMP alone, the best performance being observed ...

Lignocellulosic biomass is a renewable resource that can be utilized for the production of biofuels, chemicals, and bio-based materials. Biochemical conversion of lignocellulose to advanced biofuels, such as cellulosic ethanol, is generally performed through microbial fermentation of sugars generated by thermochemical pretreatment of the biomass followed by an enzymatic hydrolysis of the cellulose. The aims of the research presented in this thesis were to address problems associated with pretreatment by-products that inhibit microbial and enzymatic biocatalysts, and to investigate the potential of utilizing residual streams from pulp mills and biorefineries to produce hydrolytic enzymes.. A novel method to detoxify lignocellulosic hydrolysates to improve the fermentability was investigated in experiments with the yeast Saccharomyces cerevisiae. The method is based on treatment of lignocellulosic slurries and hydrolysates with reducing agents, such as sodium dithionite and sodium sulfite. The ...

If you can imagine a future powered by sustainable food and fuels; if you can imagine a future where globalism means that appropriate technologies are employed where they work best to the globes greatest advantage; if you can imagine a future of cooperation and collaboration to work out humankinds tensions, then you see a future envisioned by Advanced Biofuels USA.. The future of the advanced biofuels industry is at a critical crossroads. In the US, the Renewable Fuel Standard has created a demand of 15 billion gallons/year of corn ethanol, an amount which covers about 10% of the US market and provides renewable octane by replacing carcinogenic MTBE. US and Brazilian sources have filled this demand. However, the US seems stuck on the 15 billion/year plateau providing no meaningful demand for advanced motor vehicle biofuels. Even the Renewable Fuel Standard (RFS) has little impact since it has not been used by the government to push for more investment in advanced biofuels. Once corn ethanol ...

phdthesis{7735bdfa-90b6-441e-92a0-12388cec158d, abstract = {The fermentation of lignocellulose hydrolysates by Saccharomyces cerevisiae for ethanol production was investigated. An important problem for the successful conversion of these hydrolysates is that they often are inhibitory. The physiological effect of the furan inhibitors 5-hydroxymethyl furfural (HMF) and furfural were therefore studied, and based on the results novel strains were constructed. An additional problem for ethanol production is the by-product formation which reduces the ethanol yield. One major by-product during fermentation is glycerol, which is, furthermore, overproduced during hyperosmotic stress. Glycerol formation during anaerobic and hyperosmotic stress conditions was studied in the present work.,br/,,br, ,br/,,br, It was shown that the enzymes alcohol dehydrogenase, aldehyde dehydrogenase and pyruvate dehydrogenase, all in the central carbon metabolism of S. cerevisiae, were strongly inhibited by furfural.

Process for the manufacture of furfural wherein a pentosan-containing raw material acidified or not, is heated to a temperature T 1 by admitting steam through valve 2 while the valves 3 and 4 are closed. During the very short heating process, the steam condenses, thus increasing the moisture content of the charge. Then, valve 2 is closed and a leak valve 3 is opened so as to produce a steady ...

Anellotech, a sustainable technology company, has achieved new milestones in its pursuit of a 100-percent bio-based bottle. The pilot project uses Anellotechs Bio-TCat technology, which is an efficient thermal catalytic process that converts non-food biomass feedstock material into BTX aromatics. BTX aromatics is a group of renewable chemicals identical to their petroleum-based counterparts. The process can also produce other petroleum distillates for fuels. Anellotechs core technology, thermo catalytic biomass conversion (BioTCat), is based on scientific research initially performed in Professor George Hubers lab at the . . .

article{1149352, abstract = {Glycerol, the main by-product of biodiesel production, has been considered a renewable chemical for large scale production of a new potent fuel-additive, namely solketal tertbutyl ether (STBE). Delta Biovalue BV, a major biodiesel manufacturer in the European Union, Corning Incorporated, a manufacturer of modular Advanced-Flow (TM) glass reactors and SynBioC, a research group with a long-standing interest and know-how in flow and renewable chemistry have collaborated to develop a new process aimed at performing the transformation of glycerol in STBE under flow conditions.
