Removal of diacetyl from beer by adsorbants and diacetyl reductase
Biotechnology and Bioengineering, 1979AbstractRemoval of diacetyl from beer with adsorbants like cellulose, silica gel, activated charcoal, calcium phosphate gel, anion‐ and cation‐exchange resins, and silicylic acid black soil bed (SABSB) was attempted in comparison with the enzyme diacetyl reductase (EC 1.1.1.5).

The Journal of Chemical Physics, 1940
Diacetyl, in the vapor phase or in water solution, exhibits a bright green fluorescence when excited with light within its absorption band in the violet and near ultraviolet. A detailed measurement of the structure shows that the spectrum is the same as is shown in the fluorescence of acetone vapor when excited with λ3130.

The vibrational spectra of diacetyl and diacetyl‐d6
Zeitschrift für Elektrochemie, Berichte der Bunsengesellschaft für physikalische Chemie, 1960AbstractThe infrared and Raman spectra of diacetyl and diacetyl‐d6 have been measured, and vibrational assignments are proposed for the fundamental bands and for several infrared active combination bands. The Raman spectrum of diacetyl‐d6 has not hitherto been determined, and only a few of the stronger Raman bands of diacetyl have been reported in ...

Biosynthesis of Diacetyl in Bacteria and Yeast
Journal of Bacteriology, 1968Both diacetyl and acetoin were produced by cell-free extracts and cultures of Pseudomonas fluorescens, Aerobacter aerogenes, Lactobacillus brevis , and Saccharomyces cerevisiae 299, whereas only acetoin was produced by cell-free extracts and cultures of Streptococcus lactis ...

Toxicological Reviews, 2006
Diacetyl is a diketone flavouring agent that is commonly employed for buttery taste as well as other purposes. Industrial exposure to flavouring agents, particularly diacetyl, has recently been associated with bronchiolitis obliterans, a severe respiratory illness producing fibrosis and obstruction of the small airways.

Hydrolysis Kinetics of Diacetyl Nadolol
Journal of Pharmaceutical Sciences, 1987Diacetyl nadolol, a prodrug of nadolol and a beta-blocker, has corneal permeability approximately 20 times higher than that of its parent compound due to its higher lipophilicity. Hydrolysis studies were conducted for diacetyl nadolol at various elevated temperatures and pH values to provide stability information for its ophthalmic preparations.

OLFACTORY RESPONSIVENESS TO DIACETYL
Journal of Sensory Studies, 1994ABSTRACTOdor thresholds in the headspace over aqueous solutions of diacetyl (butane‐2,3‐dione) were measured in quadruplicate by a forced‐choice procedure in 53 individuals. Mean individual thresholds varied over a factor of 256, with the group average at .005 μg/ml. Thresholds showed a modest negative correlation with suprathreshold intensity ratings.
