Volatile Organic Compounds in apples: from biosynthesis to compound identification

open access: yesLaimburg Journal, 2021
Apple is one of the mostwidely consumed fruit and its popularity is due to the complex aroma and flavour composition. The aim of this paper is to highlight the role of volatile organic compounds (VOCs) in apples, summarizing their biosynthetic processes,

Volatile organic compound patterns predict fungal trophic mode and lifestyle

open access: yesCommunications Biology, 2021
Guo et al. characterize the volatilomes of 43 fungal species using an automated cuvette system and mass spectrometry. Their results show that VOC patterns can predict trophic modes, symbiotic lifestyle, substrate-use and host-type of fungi.

Quantitative volatile organic compound sensing with liquid crystal core fibers

open access: yesCell Reports Physical Science, 2021
Summary: Polymer fibers with liquid crystals (LCs) in the core have potential as autonomous sensors of airborne volatile organic compounds (VOCs), with a high surface-to-volume ratio enabling fast and sensitive response and an attractive non-woven ...

Modeling-based determination of physiological parameters of systemic VOCs by breath gas analysis: a pilot study

open access: yes, 2015
In this paper we develop a simple two compartment model which extends the Farhi equation to the case when the inhaled concentration of a volatile organic compound (VOC) is not zero.

Microbial degradation of dimethylsulphide and related C1-sulphur compounds: organisms and pathways controlling fluxes of sulphur in the biosphere [PDF]

open access: yes, 2010
Dimethylsulphide (DMS) plays a major role in the global sulphur cycle. It has important implications for atmospheric chemistry, climate regulation, and sulphur transport from the marine to the atmospheric and terrestrial environments.

Seasonal measurements of total OH reactivity fluxes, total ozone loss rates and missing emissions from Norway spruce in 2011 [Discussion paper] [PDF]

open access: yes, 2012
Numerous reactive volatile organic compounds (VOCs) are emitted into the atmosphere by vegetation. Most biogenic VOCs are highly reactive towards the atmosphere's most important oxidant, the hydroxyl (OH) radical.

A pilot study exploring the use of breath analysis to differentiate healthy cattle from cattle experimentally infected with Mycobacterium bovis.

open access: yesPLoS ONE, 2014
Bovine tuberculosis, caused by Mycobacterium bovis, is a zoonotic disease of international public health importance. Ante-mortem surveillance is essential for control; however, current surveillance tests are hampered by limitations affecting ease of use ...

Nickel-Oxide Based Thick-Film Gas Sensors for Volatile Organic Compound Detection

open access: yesChemosensors, 2021
In this paper, we report on the development of a highly sensitive and humidity-tolerant metal-oxide-based volatile organic compound (VOC) sensor, capable of rapidly detecting low concentrations of VOCs.
