PTR-TOF-MS analysis of volatile compounds in olive fruits.
BACKGROUND Volatile compounds of Cellina di Nardò and Ogliarola Barese, two typical Italian olive varieties, have been characterised at different ripening stages. Proton transfer reaction-time-of-flight-mass spectrometry (PTR-TOF-MS) was used for the first time on these fruits with the aim of characterising the volatile profile and, in the case of Ogliarola, the changes which may occur during t...
متن کاملVolatile sulfur compounds as a predictor for esophagogastroduodenal mucosal injury.
BACKGROUND/AIMS Halitosis is a symptom that bothers patients more socially than medically and its pathogenic mechanisms are unclear and treatment armamenterium is limited. Clinicians generally ignored active interventions. Since halitosis is closely associated with volatile sulfur compounds (VSCs), we used a Halimeter and gas chromatography to measure VSCs in patients with Helicobacter-pylori (...
متن کاملVolatile organic compounds: a bacterial contribution to plant sulfur nutrition.
In the decade since it was first reported that volatile organic compounds (VOCs) released by bacteria can promote plant growth, it has become clear that VOC-mediated interactions between bacteria and plants are widespread (reviewed in Bailly and Weisskopf, 2012). The effects of VOCs on plants have been found to vary, ranging from plant growth promotion to inhibition, even within the same combin...
متن کاملEmission of volatile sulfur compounds from spruce trees.
Spruce (Picea Abies L.) trees from the same clone were supplied with different, but low, amounts of plant available sulfate in the soil (9.7-18.1 milligrams per 100 grams of soil). Branches attached to the trees were enclosed in a dynamic gas exchange cuvette and analyzed for the emission of volatile sulfur compounds. Independent of the sulfate supply in the soil, H(2)S was the predominant redu...
متن کاملProduction of volatile organic sulfur compounds (VOSCs) by basidiomycetous yeasts.
Thirty-seven basidiomycetous yeasts belonging to 30 species of seven genera were grown on media containing l-cysteine or l-methionine as sole nitrogen sources with the objective of evaluating volatile organic sulfur compound (VOSC) production. The headspace of yeast cultures was analyzed by the solid-phase microextraction (SPME) sampling method, and volatile compounds were quantified and identi...
