BACKGROUND The non-conventional yeast Arxula adeninivorans uses 1-butanol as a carbon source and has recently attracted attention as a promising organism for 1-butanol production. Alcohol dehydrogenases (adhp) are important catalysts in 1-butanol metabolism, but only Aadh1p from Arxula has been characterized. This enzyme is involved in ethanol synthesis but has a low impact on 1-butanol degrada...
Pseudomonas butanovora grown on butane or 1-butanol expresses two 1-butanol dehydrogenases, a quinoprotein (BOH) and a quinohemoprotein (BDH). BOH exhibited high affinity towards 1-butanol (K(m) = 1.7 +/- 0.2 microM). BOH also oxidized butyraldehyde and 2-butanol (K(m) = 369 +/- 85 microM and K(m) = 662 +/- 98 microM, respectively). The mRNA induction profiles of BOH and BDH at three different ...
Butanol, an alcohol which can be produced from biomass sources, has received recent interest as an alternative to gasoline for use in spark ignition engines and as a possible blending compound with fossil diesel or biodiesel. Therefore, the autoignition of the four isomers of butanol (1-butanol, 2-butanol, iso-butanol, and tert-butanol) has been experimentally studied at high temperatures in a ...
BACKGROUND Butanol is a promising next generation fuel and a bulk chemical precursor. Although clostridia are the primary industrial microbes for the fermentative production of 1-butanol, alternative engineered hosts have the potential to generate 1-butanol from alternative carbon feedstocks via synthetic metabolic pathways. Methylobacterium extorquens AM1, a facultative methylotrophic α-proteo...
Recent studies in higher plants or animals have shown that phospholipase D (PLD) signaling regulates many aspects of development, including organization of microtubules (MTs), actin and the endomembrane system. PLD hydrolyzes structural phospholipids to form the second messenger phosphatidic acid (PA). To begin to understand the signaling pathways and molecules that regulate cytoskeletal and en...
Compared to ethanol, butanol offers many advantages as a substitute for gasoline because of higher energy content and higher hydrophobicity. Typically, 1-butanol is produced by Clostridium in a mixed-product fermentation. To facilitate strain improvement for specificity and productivity, we engineered a synthetic pathway in Escherichia coli and demonstrated the production of 1-butanol from this...
Pervaporation (PV) has shown great potential in the separation of butanol aqueous solutions due to their economic and environmental benefits. This work applies polydimethylsiloxane (PDMS) composite membrane separate four isomers (n-butanol, isobutanol, sec-butanol tert-butanol) solution. Based on physical chemical properties isomers, such as solubility, polarity interaction parameter, we system...
