Alcohol-induced biphasic inhibition of myosin subfragment 1 K-EDTA-ATPase. (1/210)

Butanol-induced inhibition of K-EDTA-ATPase of myosin subfragment 1 proceeded by biphasic kinetics, consisting of rapid and slow inactivations. The extent of the rapid inactivation, which was estimated by extrapolating the process of slow inactivation to zero time of the incubation period, was saturated with butanol concentration. Recovery of activity by dilution in the rapid phase indicates that the rapid process is reversible. The slow inactivation was concomitant with a partial denaturation of the 50 kDa domain of S1, which was detected by limited tryptic digestion. Other alcohols (methanol, ethanol, propanol and hexanol) also inhibited the K-EDTA-ATPase in the rapid phase. The Ki decreased with an increase in the number of methylene groups of alcohol. When K-EDTA-ATPase activity in the rapid phase was plotted against viscosity, surface tension or dielectric constant, the curves were different for each of the various alcohol solutions. The rapid inactivation appears to be caused by a binding of the alkyl group to S1, rather than by solvent effects. The kinetics of rapid butanol inhibitions indicate that butanol reduces the maximum activity of ATPase but enhances an apparent affinity of S1 with ATP. These indications suggest that alcohol stabilizes S1.KATP intermediate. The rapid K-EDTA-ATPase inhibition was observed at the same alcohol concentration where S1 Mg-ATPase was activated.  (+info)

Lysophosphatidic acid increases intracellular H2O2 by phospholipase D and RhoA in rat-2 fibroblasts. (2/210)

We have investigated the possible roles of phospholipase D (PLD) and RhoA in the production of intracellular H2O2 and actin polymerization in response to lysophosphatidic acid (LPA) in Rat-2 fibroblasts. LPA increased intracellular H2O2, with a maximal increase at 30 min, which was blocked by the catalase from Aspergillus niger. The LPA-stimulated production of H2O2 was inhibited by 1-butanol or PKC-downregulation, but not by 2-butanol. Purified phosphatidic acid (PA) also increased intracellular H2O2 and the increase was inhibited by the catalase. The role of RhoA was studied by the scrape-loading of C3 transferase into the cells. The C3 toxin, which inhibited stress fiber formation stimulated by LPA, blocked the H2O2 production in response to LPA or PA, but had no inhibitory effect on the activation of PLD by LPA. Exogenous H2O2 increased F-actin content by stress fiber formation. In addition, catalase inhibited actin polymerization activated by LPA, PA, or H2O2, indicated the role of H2O2 in actin polymerization. These results suggest that LPA increased intracellular H2O2 by the activation of PLD and RhoA, and that intracellular H2O2 was required for the LPA-stimulated stress fiber formation.  (+info)

beta-glycosidase from the hyperthermophilic archaeon Sulfolobus solfataricus: structure and activity in the presence of alcohols. (3/210)

beta-Glycosidase from the extreme thermophilic archaeon Sulfolobus solfataricus is a tetrameric protein with a molecular mass of 240 kDa, stable in the presence of detergents, and with a maximal activity at temperatures above 95 degrees C. Understanding the structure-activity relationships of the enzyme under different conditions is of fundamental importance for both theoretical and applicative purposes. In this paper we report the effect of methanol, ethanol, 1-propanol, and 1-butanol on the activity of S. solfataricus beta-glycosidase expressed in Escherichia coli. The alcohols stimulated the enzyme activity, with 1-butanol producing its maximum effect at a lower concentration than the other alcohols. The structure of the enzyme was studied in the presence of 1-butanol by circular dichroism, and Fourier-transform infrared and fluorescence spectroscopies. Circular dichroism and steady-state fluorescence measurements revealed that at low temperatures the presence of the alcohol produced no significant changes in the tertiary structure of the enzyme. However, time-resolved fluorescence data showed that the alcohol modifies the protein microenvironment, leading to a more flexible enzyme structure, which is probably responsible for the enhanced enzymatic activity.  (+info)

Diversity in butane monooxygenases among butane-grown bacteria. (4/210)

Butane monooxygenases of butane-grown Pseudomonas butanovora, Mycobacterium vaccae JOB5, and an environmental isolate, CF8, were compared at the physiological level. The presence of butane monooxygenases in these bacteria was indicated by the following results. (i) O(2) was required for butane degradation. (ii) 1-Butanol was produced during butane degradation. (iii) Acetylene inhibited both butane oxidation and 1-butanol production. The responses to the known monooxygenase inactivator, ethylene, and inhibitor, allyl thiourea (ATU), discriminated butane degradation among the three bacteria. Ethylene irreversibly inactivated butane oxidation by P. butanovora but not by M. vaccae or CF8. In contrast, butane oxidation by only CF8 was strongly inhibited by ATU. In all three strains of butane-grown bacteria, specific polypeptides were labeled in the presence of [(14)C]acetylene. The [(14)C]acetylene labeling patterns were different among the three bacteria. Exposure of lactate-grown CF8 and P. butanovora and glucose-grown M. vaccae to butane induced butane oxidation activity as well as the specific acetylene-binding polypeptides. Ammonia was oxidized by all three bacteria. P. butanovora oxidized ammonia to hydroxylamine, while CF8 and M. vaccae produced nitrite. All three bacteria oxidized ethylene to ethylene oxide. Methane oxidation was not detected by any of the bacteria. The results indicate the presence of three distinct butane monooxygenases in butane-grown P. butanovora, M. vaccae, and CF8.  (+info)

Short-chain alcohols promote an early stage of membrane hemifusion. (5/210)

Hemifusion, the linkage of contacting lipid monolayers of two membranes before the opening of a fusion pore, is hypothesized to proceed through the formation of a stalk intermediate, a local and strongly bent connection between membranes. When the monolayers' propensity to bend does not support the stalk (e.g., as it is when lysophosphatidylcholine is added), hemifusion is inhibited. In contrast, short-chain alcohols, reported to affect monolayer bending in a manner similar to that of lysophosphatidylcholine, were here found to promote hemifusion between fluorescently labeled liposomes and planar lipid bilayers. Single hemifusion events were detected by fluorescence microscopy. Methanol or ethanol (1.2-1.6 w/w %) added to the same compartment of the planar bilayer chamber as liposomes caused a 5-50 times increase in the number of hemifusion events. Alcohol-induced hemifusion was inhibited by lysophosphatidylcholine. Promotion of membrane hemifusion by short-chain alcohol was also observed for cell-cell fusion mediated by influenza virus hemagglutinin (HA). Alcohol promoted a fusion stage subsequent to the low pH-dependent activation of HA. We propose that binding of short-chain alcohol to the surface of membranes promotes hemifusion by facilitating the transient breakage of the continuity of each of the contacting monolayers, which is required for their subsequent merger in the stalk intermediate.  (+info)

Trp-Lys-Tyr-Met-Val-D-Met is a chemoattractant for human phagocytic cells. (6/210)

Trp-Lys-Tyr-Met-Val-D-Met (WKYMVm) is a synthetic peptide that stimulates phosphoinositide (PI) hydrolysis in human leukocytes. The peptide binds to a unique cell surface receptor(s). Recently we had demonstrated that human neutrophils, monocytes, and B lymphocytes express this peptide-specific receptor and that stimulation of human leukocytes with the peptide leads to activation of the oxidative respiratory system and the bactericidal activity of neutrophils or monocytes. In this study we showed that the peptide induces chemotaxis of phagocytic leukocytes and studied the signaling pathway leading to chemotaxis in human monocytes. The peptide-induced monocyte chemotaxis is pertussis toxin (PTX)-sensitive. This fact correlates with the peptide's stimulation of PI hydrolysis and intracellular Ca2+ ([Ca2+]i) release, which is also PTX-sensitive. We demonstrate that the peptide-specific receptor is different from receptor(s) for monocyte chemoattractant protein-1 (MCP-1). We also show that intracellular signaling of WKYMVm leading to monocyte chemotaxis is different from that of MCP-1. The peptide-mediated monocyte chemotaxis is insensitive to protein kinase C (PKC) inhibitor (GF109203X) and butan-1-ol, ruling out PKC and phospholipase D participation in this process. On the other hand, a tyrosine kinase inhibitor (genistein) and RhoA inhibitor (C3 transferase) curtailed the peptide-induced chemotaxis in a concentration-dependent manner, implying the involvement of tyrosine kinase and RhoA, respectively. Treatment of human monocytes with the peptide stimulates tyrosine phosphorylation of several cellular proteins, including p125FAK and Pyk2 and translocation of RhoA from the cytosol to the membrane. We conclude that WKYMVm induces chemotaxis of human phagocytic leukocytes via unique receptors and signaling.  (+info)

Ethanol increases superoxide anion production stimulated with 4beta-phorbol 12-myristate 13-acetate in human polymorphonuclear leukocytes. Involvement of protein kinase C. (7/210)

Stimulation of human polymorphonuclear leukocytes (PMNs) with PMA initiates a cascade of events leading to the production and release of superoxide anion (O-2), a major component in anti-bacterial defense. Generation of O-2 by PMA-stimulated PMNs occurs through the translocation and activation of protein kinase C (PKC). In this study, using freshly isolated PMNs, we examined the effect of ethanol on this response to PMA. Our results show that the basal production of O-2 was not affected by ethanol. In contrast, the response induced by PMA was potentiated by ethanol. This potentiation was observed even at high doses of PMA (200 nM) which alone had stimulated the O-2 response maximally. This enhanced response was not due to an increase of PMA uptake by PMNs. The maximal effect was obtained when the cells were preincubated with 80 mM of ethanol before PMA stimulation. Measurement of PKC activity in the cytosolic and membrane fractions showed that pretreatment of PMNs with ethanol increased twofold the PMA-stimulated PKC activity in the membrane fraction. Furthermore, Western blot analysis verified that this increase in PKC activity in the membrane fraction was linked to an increase in the translocation of PKC-alpha and -beta isoforms to the membrane. These results suggest that ethanol potentiates PMA-induced O-2 production through increasing PKC translocation and activity in PMNs.  (+info)

General anesthetic action at an internal protein site involving the S4-S5 cytoplasmic loop of a neuronal K(+) channel. (8/210)

The structural bases of general anesthetic action on a neuronal K(+) channel were investigated using the series of homologous 1-alkanols, electrophysiology, and mutational analysis. Domain swapping between dShaw2 (alkanol-sensitive) and hKv3.4 (alkanol-resistant) and site-directed mutagenesis demonstrated that a 13-amino acid cytoplasmic loop (S4-S5) determines the selective inhibition of native dShaw2 channels by 1-alkanols. The S4-S5 loop may contribute to a receptor for both 1-alkanols and the inactivation particle, because the enhanced 1-alkanol sensitivity of hKv3.4 channels hosting S4-S5 mutations correlates directly with disrupted channel inactivation. Evidence of a discrete protein site was also obtained from the analysis of the relationship between potency and alkyl chain length, which begins to level off after 1-hexanol. Rapid application to the cytoplasmic side of inside-out membrane patches shows that the interaction between dShaw2 channels and 1-alkanols equilibrates in <200 ms. By contrast, the equilibration time is >1000-fold slower when the drug is applied externally to outside-out membrane patches. The data strongly favor a mechanism of inhibition involving a discrete internal site for 1-alkanols in dShaw2 K(+) channels. A new working hypothesis proposes that 1-alkanols lock dShaw2 channels in their closed conformation by a direct interaction at a crevice formed by the S4-S5 loop.  (+info)

One of the most controversial parts of the threshold is that its decided by the judge after a jury has already made their verdict. Meaning that, after the jury has decided on an award at the conclusion of a trial, the defense can bring a threshold motion in front of the judge alone.. The judge isnt bound by the verdict of the jury and will have to determine whether or not the injuries breach the threshold test. In the threshold test, the judge will asses the plaintiffs injuries in three parts.. First, the judge will consider whether the impairment caused by the injuries can be considered permanent. In order to asses this, theyll look at the plaintiffs medical records and history of treatment. Theyll also take into consideration witness testimony.. Second, the judge will consider whether the impairment caused by the injuries can be considered serious. Seriousness is more subjective and difficult to define but, generally, the judge will look at how the impairment has impacted the plaintiffs ...

Batch fermentation was performed to investigate the effects of pH and temperature on the butanol production of Clostridium pasteurianum DSM 525 using a synthetic medium containing glycerol as a sole source of carbon and energy. C. pasteurianum DSM 525 showed a good growth at the initial glycerol concentration of 40 g/L, the temperature of 37 ℃, and a pH range from 5.0 to 6.5. The growth rate and the proportion of butanol among the fermentation products increased as the culture pH decreased, but the final glycerol consumption decreased at lower pHs, probably due to the reduced tolerance to butanol at lower pHs. The growth rate and the proportion of butanol increased as the temperature of the medium increased from 25, to 30, and to 37 ℃. However, more butanol was produced at lower temperatures (18.7, 16.8, and 11.5 g/L of butanol were finally produced at the temperatures of 25, 30, and 37 ℃, respectively), probably due to the reduced toxicity of butanol at lower temperatures. These results ...
Factorial design and response surface techniques were used in combination with mathematical modelling and computational simulation to optimise an innovative industrial bioprocess, the production of biobutanol employing the flash fermentation technology. A parametric analysis performed by means of a full factorial design at two levels determined the influence of operating variables on butanol yield and productivity. A second set of simulations were carried out based on the central composite rotatable design. This procedure generated simplified statistical models that describe butanol yield and productivity as functions of the significant operating variables. From these models, response surfaces were obtained and used to optimise the process. For a range of substrate concentration from 130 to 180 g/l, the optimum operating ranges ensure butanol productivity between 7.0 and 8.0 g/l h, butanol yield between 19 and 22%, substrate conversion above 90% and final butanol concentration around 25 g/l.

Butanol is an important biofuel and chemical. The development of butanol-tolerant strains and the identification of functional butanol-tolerant genes is essential for high-yield bio-butanol production due to the toxicity of butanol. Escherichia coli BW25113 was subjected for the first time to error-prone PCR-based whole-genome shuffling. The resulting mutants BW1847 and BW1857 were found to tolerate 2% (v/v) butanol and short-chain alcohols, including ethanol, isobutanol, and 1-pentanol. The mutants exhibited good stability under butanol stress, indicating that they are potential host strains for the construction of butanol pathways. BW1847 had better butanol tolerance than BW1857 under 0-0.75% (v/v) butanol stress, but showed a lower tolerance than BW1857 under 1.25-2% (v/v) butanol stress. Genome resequencing and PCR confirmation revealed that BW1847 and BW1857 had nine and seven single nucleotide polymorphisms, respectively, and a common 14-kb deletion.

Ethanol gets a lot of attention as the biofuel of choice in America.

Butanols advantages over ethanol arise from its gasoline-like properties. A
Why does this amaze me? Chemical companies like Celanese (my former employer), Dow, BASF, Eastman - oil companies like BP and Shell - and numerous other companies around the world produce butanol. They have big research budgets, and they would love to find an economical direct gasification route to butanol. These companies have looked at probably thousands of catalysts, and people have spent their careers working on this problem. The challenge is that syngas (produced from gasification) doesnt like to form butanol. You can form a little bit directly, but CO (carbon monoxide) likes to do lots of things besides form a C4 alcohol like butanol.. Methanol is not a problem. You can also produce ethanol, which is what Range Fuels is planning on doing (although you almost always have methanol to deal with as well). But the selectivity falls off sharply as you go to higher alcohols. By the time you get to butanol, you are lucky if 5% of the product is butanol. More typical is 1-2%. See this NREL report ...

Sustainable production of target compounds such as biofuels and high-value chemicals for pharmaceutical, agrochemical, and chemical industries is becoming an increasing priority given their current … dependency upon diminishing petrochemical resources. Designing these strains is difficult, with current methods focusing primarily on knocking-out genes, dismissing other vital steps of strain design including the overexpression and dampening of genes. The design predictions from current methods also do not translate well-into successful strains in the laboratory. Here, we introduce RobOKoD (Robust, Overexpression, Knockout and Dampening), a method for predicting strain designs for overproduction of targets. The method uses flux variability analysis to profile each reaction within the system under differing production percentages of target-compound and biomass. Using these profiles, reactions are identified as potential knockout, overexpression, or dampening targets. The identified reactions are ...

The propylene production with 1-butanol co-feeding for methanol in relation to propylene process (MTP) at 440-490 ̊C temperature range and at 0.9-15 hr-1 WHSV range over H-ZSM-5 zeolite catalyst is assessed in a isothermal fixed-bed reactor. The feedings here are of: pure 1-butanol, pure methanol and a 1-butanol and methanol mixture. The effect of 1-butanol co-feeding on selectivity of propylene is assessed through RSM an experimental design method. The results indicate that the selectivity of propylene is 69% in the feed mixture of 13, 37 and 50 wt% of 1-butanol, methanol and water, respectively. The optimum conditions to obtain high level of propylene selectivity is suggested to be at 480 ̊C, WHSV of 0.9 hr-1 and 1-butanol concentration of 0.135 wt.% through RSM method. The sensitivity analysis of the RSM method reveals that the WHSV is the most effective parameter on the propylene selectivity with a P-value of 0.003.

In the present study, metabolic engineering and adaptive laboratory evolution were integrated to improve the n-butanol production of C. cellulovorans DSM 743B from AECC, a low-cost and renewable agricultural waste. This represents an application of a previous study of genetic tools of C. cellulovorans DSM 743B in CBP-enabling microbial chassis development (6).. To enable C. cellulovorans DSM 743B to produce n-butanol, the CoA-dependent ABE pathway, including adhE1 and ctfAB-adc genes from C. acetobutylicum ATCC 824, were introduced. The metabolically engineered strains showed increased butanol output compared to results in the study of Yang et al., who overexpressed only adhE2 in C. cellulovorans and eventually achieved 1.42 g/liter n-butanol production from cellulose (28). It is interesting that ZQW03 (743B/pXY1-Pthl-adhE1) exhibited higher n-butanol output, butyraldehyde dehydrogenase activity, and butanol dehydrogenase activity than ZQW02 (743B/pXY1-Pthl-adhE2) (Fig. 2B). The higher butanol ...
TY - JOUR. T1 - Oxygen-tolerant coenzyme A-acylating aldehyde dehydrogenase facilitates efficient photosynthetic n-butanol biosynthesis in cyanobacteria. AU - Lan, Ethan I.. AU - Ro, Soo Y.. AU - Liao, James C.. PY - 2013/9/1. Y1 - 2013/9/1. N2 - Metabolic engineering of photosynthetic microorganisms such as cyanobacteria for the production of fuels or chemicals is challenging, particularly when the pathway involves oxygen-sensitive enzymes. We have previously designed a coenzyme A (CoA) dependent n-butanol biosynthesis pathway tailored to the metabolic physiology of the cyanobacterium Synechococcus elongatus PCC 7942 by incorporating an ATP driving force and a kinetically irreversible trap. However, one of the enzymes involved, CoA-acylating butyraldehyde dehydrogenase (Bldh) is oxygen sensitive, therefore hindering efficient n-butanol synthesis in cyanobacteria. To overcome this obstacle of n-butanol biosynthesis, we characterized six oxygen tolerant CoA-acylating aldehyde dehydrogenases ...
The effect of butanol challenge (0, 1.0, 1.5% [vol/vol]) and growth temperature (22, 37, 42°C) on the membrane composition and fluidity of Clostridium acetobutylicum ATCC 824 and a butanol-tolerant mutant, SA-2, was examined in chemically defined medium. Growth of strain ATCC 824 into the stationary phase coincided with a gradual increase in the percent saturated to percent unsaturated (SU) fatty acid ratio. When challenged with butanol at 22 and 37°C, ATCC 824 demonstrated an immediate (within 30 min) dose-response increase in the SU ratio. This strain showed little additional change over a 48-h fermentation. Compared with ATCC 824, growth of SA-2 into the late stationary phase at 22 or 37°C resulted in an overall greater increase in the SU ratio for both unchallenged and challenged cells. This effect was minimized when SA-2 was challenged at 42°C, probably due to the combination of the membrane fluidizing effect of butanol and the elevated temperature. Growth at 42°C resulted in an ...
Introduction. Oxidizing alcohols By: Toufa Bouchouar Partners name: Adrian Date: March 20, 2006 Teacher name: Ms. Sommer When KMnO acts as an oxidizing agent when it comes in contact with 1 butanol, 2 butanol and t- butyl which of these agents will become primary, secondary or tertiary alcohol? Introduction: Alcohols are the family of compounds that contain one or more hydroxyl (-OH) groups. They are also represented by the general formula R-OH. Alcohols are important in organic chemistry because they can be converted to and from many other types of compounds. Reactions with alcohols fall into two different categories Oxidation in organic chemistry always involves either the addition of oxygen atoms or the removal of hydrogen atoms. Whenever a molecule is oxidized, another molecule must be reduced. Therefore, these reactions require a compound that can be reduced. These compounds are usually inorganic. They are referred to as oxidizing reagents. With regards to alcohol, oxidizing reagents can ...

Like competitors LS9, OPX Biotechnologies and Amyris, Gevo is trying to change the face of the biofuel industry by using synthetic biology to engineer enzymes and microorganisms to convert cellulosic crops and waste into advanced biofuels like isobutanol and butanol. Butanol, the company claims, is superior to first-generation biofuels like corn ethanol in several respects: It has a higher energy content; does not absorb water and can easily be transported through the existing gas infrastructure; and - perhaps most importantly - can be directly pumped into current vehicles ...
In the United States alone, at least 323 million tons of cellulosic materials that could be used to produce butanol are thrown out each year.. Mullins lab first identified TU-103 in animal droppings, cultivated it, and developed a method for using it to produce butanol.. Most important about this discovery is TU-103s ability to produce butanol directly from cellulose, he says.. TU-103 is the only known butanol-producing clostridial strain that can grow and produce butanol in the presence of oxygen, which kills other butanol-producing bacteria. Having to produce butanol in an oxygen-free space increases the costs of production.. As a biofuel, butanol is superior to ethanol that is commonly produced from corn sugar, because it can readily fuel existing motor vehicles without any modifications to the engine, can be transported through existing fuel pipelines, is less corrosive, and contains more energy than ethanol, which would improve mileage.. This discovery could reduce the cost to produce ...
Butanol is one of the potential alternative biofuels due to its similarities with gasoline and low sooting tendency. In this paper, three butanol isomers (n-butanol, iso-butanol, and tert-butanol) are used as low reactive fuel while n-heptane is used as high reactive fuel in a heavy-duty engine running in RCCI mode. This work investigates the influences of butanol structure on combustion performance and emission characteristics of RCCI combustion concepts. The tested load ranges from 4 bar to 12 bar gIMEP in a step of 2 bar. Since the reactivity of the three isomers can be sequenced by n-butanol > tert-butanol> iso-butanol, different EGR rate and direct injection strategies are applied. N-butanol and tert-butanol require double direct injection and highest EGR rate to maintain a proper combustion phasing. However, iso-butanol yields in ultra-low NOx and soot emissions up to 8 bar gIMEP with single direct injection and 0% EGR due to the higher octane rating ...
Butanol is increasingly being discussed as a possible gasoline blendstock, to be used as an alternative to ethanol in meeting government mandates for clean air standards and renewable fuel obligations. Butanol is a 4-carbon alcohol that can be produced by fermentation using the same or similar feedstocks as used in ethanol production, and this, along…
TY - JOUR. T1 - Fatty-acyl chain profiles of cellular phosphoinositides. AU - Traynor-Kaplan, Alexis. AU - Kruse, Martin. AU - Dickson, Eamonn J. AU - Dai, Gucan. AU - Vivas, Oscar. AU - Yu, Haijie. AU - Whittington, Dale. AU - Hille, Bertil. PY - 2017/5/1. Y1 - 2017/5/1. N2 - Phosphoinositides are rapidly turning-over phospholipids that play key roles in intracellular signaling and modulation of membrane effectors. Through technical refinements we have improved sensitivity in the analysis of the phosphoinositide PI, PIP, and PIP2 pools from living cells using mass spectrometry. This has permitted further resolution in phosphoinositide lipidomics from cell cultures and small samples of tissue. The technique includes butanol extraction, derivatization of the lipids, post-column infusion of sodium to stabilize formation of sodiated adducts, and electrospray ionization mass spectrometry in multiple reaction monitoring mode, achieving a detection limit of 20 pg. We describe the spectrum of ...
This Small Business Innovation Research (SBIR) Phase I project will develop a costeffective butanol production and purification process. The specific aim of this project is to scaleup a butanol production system from a small, ?laboratory scale? ,2 liter volume, to a 200 liter culture volume in order to determine the feasibility of its utility for production of practical amounts of the valuable biofuel. The broader/commercial impacts of this research are that the process should be configurable for fuel and/or hydrogen production by individuals safely and with negligible environmental impact, and that demonstration of the feasibility of production of fuels by ?microrefineries? could foster growth of a network of ?cottage industries? devoted to local fuel and biochemicals production that could provide increased opportunities for employment in rural areas where carbohydraterich waste streams are available. The growth of the dairy products industry in eastern South Dakota has resulted in the ...
Besides the common myth - Upgrading Bio-ethanol is a challenging science.. Not only do the practitioners have to break down the complex biomass mixtures efficiently to synthesize bio-ethanol, but they also have to contend with numerous other equally (and often times more) important considerations such as low oil prices (per barrel), process safety, waste streams, and chemical toxicity, recycling of solvents/catalysts, process economics, and a multitude of engineering/ technology considerations. Nevertheless, despite the challenges, the ideal outcome of these efforts when accomplished is quite satisfying: a simple, efficient, green, robust, and safe manufacturing process. A showcase of green chemistry, process intensification, and catalysis along with industrial fermentation - Butanol production (with a global market of about 350 million gallons per year) has garnered wide acclaim.. Butanol is an important industrial chemical, which is currently produced by the Oxo-process starting from propylene ...
2-Metil-2-butanol (terc-amil alkohol, 2M2B, amilen hidrat) je jedan od izomera amil alkohola. On je čista, bezbojna tečnost sa jakim mirisom peperminta ili kamfora.[7][8] Kod ljudi on ispoljava sedativno, hipnotičko, i antikonvulsivno dejstvo slično etanolu pri gutanju ili udisanju.

O aumento do preço do petróleo e a tendência atual do uso de matérias-primas renováveis para a produção de produtos químicos renovam o interesse na produção de biobutanol que, produzido via fermentação de matérias-primas agrícolas, pode ser utilizado como um componente da gasolina e do óleo diesel. Com a comercialização desse novo biocombutível, poderão ocorrer danos ambientais devido ao derramamento dessas substâncias. Entre outras técnicas, a limpeza dessas áreas contaminadas pode ser alcançada com biorremediação, uma técnica baseada na ação de microrganismos, que tem a vantagem de transformar contaminantes perigosos em substâncias não tóxicas, como o CO2, água e biomassa. Assim, tendo em mente a utilização de biobutanol no futuro próximo como um aditivo gasolina e devido à falta de conhecimento dos efeitos de butanol sobre a biodegradação de gasolina, este trabalho visou avaliar a biodegradação aeróbia da concentração da mistura butanol/gasolina e ...

In order to comply with the stringent emission regulations, many researchers have been focusing on diesel-compressed natural gas (CNG) dual fuel operation in compression ignition (CI) engines. The diesel-CNG dual fuel operation mode has the potential to reduce both the soot and NOx emissions; however, the thermal efficiency is generally lower than that of the pure diesel operation, especially under the low and medium load conditions. The current experimental work investigates the potential of using diesel-1-butanol blends as the pilot fuel to improve the engine performance and emissions. Fuel blends of B0 (pure diesel), B10 (90% diesel and 10% 1-butanol by volume) and B20 (80% diesel and 20% 1-butanol) with 70% CNG substitution were compared based on an equivalent input energy at an engine speed of 1200 RPM. The results indicated that the diesel-1-butanol pilot fuel can lead to a more homogeneous mixture due to the longer ignition delay ...

To address this challenge, the PIs propose IFPs that interface stress responsive feedback promoters with inducible timing control using RNA regulators. IFPs represent a new regulatory concept for metabolic pathway control and optimization: inducibility allows titration and timing of pathway expression to be rapidly explored, while stress responsive feedback allows autonomous expression optimization. The central objective of this proposal is to develop and validate IFPs in the context of two industrially important, yet different, metabolic pathways: terpenoid oxygenation (a critical technology for Manus Bio) and n-butanol production. This objective will be pursued in aims that validate the approach of IFP regulation, create a public resource of unique IFPs applicable to many different metabolic pathways, and fine-tune IFPs that are directly applicable for use by industry in large-scale bioprocesses ...
