Pemisahan Butanol dari Campuran ABE Menggunakan Software Aspen Plus: Pengaruh Refluks Rasio terhadap Kandungan Butanol

Butanol production in S. cerevisiae via a synthetic ABE pathway is enhanced by specific metabolic engineering and butanol resistance

BACKGROUND The fermentation of sugars to alcohols by microbial systems underpins many biofuel initiatives. Short chain alcohols, like n-butanol, isobutanol and isopropanol, offer significant advantages over ethanol in terms of fuel attributes. However, production of ethanol from resistant Saccharomyces cerevisiae strains is significantly less complicated than for these alternative alcohols. R...

Acetone-butanol fermentation revisited.

4-(4-Nitro­phen­oxy)butanol

The crystal structure of the title compound, C(10)H(13)NO(4), features inter-molecular O-H⋯O(nitro) hydrogen bonding, which links mol-ecules into supra-molecular chains running parallel to the bc diagonal. There is also π-π stacking between 4-nitro-phenyl groups, the inter-planar distance between the nitro-benzene rings being 3.472 (2) Å.

Butanol-extractable iodine of serum.

It has been demonstrated chemically that the iodine bound to proteins of the serum is predominantly composed of thyroxine (1-4). The concentration of this protein-bound or serum precipitable iodine (SPI) appears to be closely correlated with the activity of the thyroid gland (5-7). It is probably the most precise clinical criterion of such activity that has yet been extensively employed. It is,...
