Determination of Key Volatile Compounds Related to Long-Term Fermentation of Soy Sauce.

Journal of Food Science, 2019
The changes of volatile compounds in soy sauce during long-term fermentation (12 months) were investigated using solid-phase microextraction (SPME) and stir bar sorptive extraction (SBSE).

Nonvolatile, semivolatile, or volatile: Redefining volatile for volatile organic compounds

Journal of the Air & Waste Management Association, 2014
Although widely used in air quality regulatory frameworks, the term "volatile organic compound" (VOC) is poorly defined. Numerous standardized tests are currently used in regulations to determine VOC content (and thus volatility), but in many cases the tests do not agree with each other, nor do they always accurately represent actual evaporation rates ...

Biofiltration of volatile organic compounds

Applied Microbiology and Biotechnology, 2005
The removal of volatile organic compounds (VOCs) from contaminated airstreams has become a major air pollution concern. Improvement of the biofiltration process commonly used for the removal of odorous compounds has led to a better control of key parameters, enabling the application of biofiltration to be extended also to the removal of VOCs. Moreover,

Microbial sensors for volatile compounds

Biochimie, 1980
A microbial sensor consisting of immobilized microorganisms, a gas permeable membrane, and an oxygen electrode was prepared for the continuous determination of methyl alcohol. Immobilized methyl alcohol utilizing bacteria was employed for the sensor. The response time of the sensor was within 10 min by the steady-state method. A linear relationship was

VOLATILE COMPOUNDS FROM Haplophyllum myrtifolium

Chemistry of Natural Compounds, 2001
The volatile fractions of the petroleum ether extract and of the alkaloid extract ofHaplophyllum myrtifoliumBoiss., endemic to Turkey, were trapped by using the Solid Phase Micro Extraction (SPME) technique and analyzed by GC/MS. Forty-seven compounds were characterized from the petroleum ether extract of the aerial parts with β-caryophyllene (14.6 %),

Volatile Compounds from Melicope obscura

Chemistry & Biodiversity, 2010
AbstractTo evaluate the interpopulation variability of volatile compounds in Melicope obscura, four samples representing four populations were collected all over the distribution area of the species in Reunion Island (Indian Ocean). The samples were extracted by hydrodistillation, and analyzed using GC/FID and GC/MS techniques. The study revealed that,

Soil volatile fungistasis and volatile fungistatic compounds

Soil Biology and Biochemistry, 2004
Abstract Fungistasis is a widespread phenomenon that can be mediated by soil microorganisms and volatile organic compounds (VOCs). The relationship between soil microorganisms and VOCs is still unclear, however, and many fungistatic compounds remain to be identified.
