Densities of methyl-ethyl-ketone + 2-butanol were measured at temperatures between -10 and 80 degreesC, working with the pure species and nine binary mixtures. At each experimental condition, the data were correlated by means of some empirical equations and according to well-established literature...
Extract the sample once with 2 volumes of chloroform:isoamyl alcohol (4:1, v/v) or with 2 volumes of chloroform:butanol (4:1, v/v).Pulsecentrifuge to separate the two phases. Transfer the upper aqueous phase to an autoclaved microfuge tube. ...
It is worth noting that atmospheric oxygen acts as an inhibitor of this process; hence it is necessary to protect the gel by covering its surface with water or butanol. Because the polymerization reaction is exothermic, the best results are obtained by keeping the system in a refrigerator. ...
The γ-ray attenuation in a thick butanol sample has been measured at 293 K and 4 K. The hydrogen density in the butanol target at 4 K was determined with an uncertainty of ±1%.doi:10.1007/978-3-642-76661-9_76S. RobinsonR. Henneck...

To test whether increasing the copy number of the heterologous gene improves production of the respective sesquiterpene, the highest titer epi-isozizaene (EIZS2 and EIZS4) and prespatane (PPS2 and PPS4) strains were transformed with construct 3 and construct 7, respectively, creating strains EI...

Non-limiting examples of suitable alcohols include ethanol, propanol, isopropanol, butanol, isobutanol, 2-methyl-pentanol, 2-ethylhexanol, etc. While it is believed that almost any alcohol may be utilized, linear or branched, a higher order branched alcohol, for example, 2-ethyl-1-hexanol, can...
We searched the genome of WAC07094 for genes that may direct the synthesis of extracellular signaling molecules, including butyrolactone and butanolide synthases (commonly used by streptomycetes to synthesize gamma-butyrolactone/butanolide signaling molecules), as well as small peptides like those ...
