Olfactometry Profiles and Quantitation of Volatile Sulfur Compounds of Swiss Tilsit Cheeses.

Pascal Fuchsmann et al.

Journal of agricultural and food chemistry, 63(34), 7511-7521 (2015-08-01)

To establish the odor profiles of three differently fabricated commercial Swiss Tilsit cheeses, analyses were conducted using headspace solid-phase microextraction gas chromatography-mass spectrometry/pulsed flame photometric detection and gas chromatography-olfactometry to identify and quantitate volatile compounds. In addition, odor quality and

Infrared emission following photolysis of methylisothiocyanate and methylthiocyanate.

Elisabeth A Wade et al.

The journal of physical chemistry. A, 115(21), 5319-5323 (2011-05-11)

Methylisothiocyanate (CH(3)NCS) was photolyzed at 193 and 248 nm, and the resulting time-resolved infrared emission was observed. Similar experiments were performed on methylthiocyanate (CH(3)SCN) photolyzed at 193 nm. Previous work suggested that these isomers undergo excited-state isomerization prior to dissociation

Quantification of methyl thiocyanate in the headspace of Pseudomonas aeruginosa cultures and in the breath of cystic fibrosis patients by selected ion flow tube mass spectrometry.

Violetta Shestivska et al.

Rapid communications in mass spectrometry : RCM, 25(17), 2459-2467 (2011-08-06)

Infection by Pseudomonas aeruginosa (PA) is a major cause of morbidity and mortality in patients with cystic fibrosis (CF). Breath analysis could potentially be a useful diagnostic of such infection, and analyses of volatile organic compounds (VOCs) emitted from PA

Determination of methionine sulfoxide in proteins: comparison of a gas-chromatographic and electrophoretic method.

G Amiconi et al.

Journal of biochemical and biophysical methods, 11(4-5), 241-249 (1985-10-01)

Two methods for the determination of methionine in proteins have been used to estimate the extent of methionine sulfoxide obtained upon exposure of proteins to oxidizing agents. Both methods are based on prior treatment with cyanogen bromide, which attacks methionines

Arabidopsis HARMLESS TO OZONE LAYER protein methylates a glucosinolate breakdown product and functions in resistance to Pseudomonas syringae pv. maculicola.

Yukari Nagatoshi et al.

The Journal of biological chemistry, 284(29), 19301-19309 (2009-05-08)

Almost all of the chlorine-containing gas emitted from natural sources is methyl chloride (CH(3)Cl), which contributes to the destruction of the stratospheric ozone layer. Tropical and subtropical plants emit substantial amounts of CH(3)Cl. A gene involved in CH(3)Cl emission from

Chemotaxis away from thiocyanic and isothiocyanic esters in Pseudomonas aeruginosa.

T Ohga et al.

FEMS microbiology letters, 113(1), 63-66 (1993-10-01)

Negative chemotaxis, the movement of organisms away from chemicals, was investigated in Pseudomonas aeruginosa using a rapid videotape method. Digital image processing was used to detect changes in bacterial numbers near the mouth of a capillary containing a test chemical.
