Applications of Solid Phase Microextraction, 674-674 (1999)

Headspace Solid Phase Microextraction Coupled to GC/MS for the Analysis of Volatiles of Honeys from Arid and Mediterranean Areas of Algeria.

Abdelhamid Neggad et al.

Chemistry & biodiversity, 16(10), e1900267-e1900267 (2019-08-17)

The volatile composition of seven honey samples collected from various regions of Algeria and feeding on different plants have been determined. The Headspace Solid-Phase MicroExtraction (HS-SPME) coupled with Gas Chromatography-Mass Spectrometry (GC/MS) was used to achieve the purpose. In this

Determination of Pyrethroids in Tea Brew by GC-MS Combined with SPME with Multiwalled Carbon Nanotube Coated Fiber.

Dongxia Ren et al.

International journal of analytical chemistry, 2018, 8426598-8426598 (2018-05-01)

A new method has been developed to simultaneously determine 7 pyrethroid residues in tea brew using gas chromatography-mass spectrometry (GC-MS) combined with solid phase microextraction (SPME) with multiwalled carbon nanotubes (MWCNTs) coated fiber. The MWCNTs coated fiber of SPME was

Investigations on Metabolic Changes in Beagle Dogs Fed Probiotic Queso Blanco Cheese and Identification of Candidate Probiotic Fecal Biomarkers Using Metabolomics Approaches.

Ye Jin Kim et al.

Metabolites, 10(8) (2020-07-30)

Intake of probiotic cheese improves the intestinal health of humans and animals. However, metabolic changes in the intestines of dogs in response to the ingestion of probiotic cheese have not been evaluated. Thus, we aimed to determine the metabolic changes

Analysis of ammonium nitrate headspace by on-fiber solid phase microextraction derivatization with gas chromatography mass spectrometry.

Adam L Lubrano et al.

Journal of chromatography. A, 1429, 8-12 (2016-01-01)

A novel analytical method has been developed for the quantitation of trace levels of ammonia in the headspace of ammonium nitrate (AN) using derivatized solid phase microextraction (SPME) fibers with gas chromatography mass spectrometry (GC-MS). Ammonia is difficult to detect

A Simple Alternative Method for Preservation of 2-Methylisoborneol in Water Samples.

Chun-Cheng Fan et al.

International journal of environmental research and public health, 15(5) (2018-05-23)

2-Methylisoborneol (2-MIB) is one of the most commonly observed taste and odor (T&O) compounds present in drinking water sources. As it is biodegradable, a preservation agent, typically mercury chloride, is needed if the water is not analyzed right after sampling.

Solid Phase Microextraction: A Practical Guide, 257-257 (1999)

Forest tree associated bacteria for potential biological control of Fusarium solani and of Fusarium kuroshium, causal agent of Fusarium dieback.

Nailea Báez-Vallejo et al.

Microbiological research, 235, 126440-126440 (2020-02-29)

Although the use of crop-associated bacteria as biological control agents of fungal diseases has gained increasing interest, the biotechnological potential of forest tree-associated microbes and their natural products has scarcely been investigated. The objective of this study was to identify

Potential application of CHS and 4CL genes from grape endophytic fungus in production of naringenin and resveratrol and the improvement of polyphenol profiles and flavour of wine.

Yao Lu et al.

Food chemistry, 347, 128972-128972 (2021-01-17)

4-Coumaroyl-CoA ligase (Al4CL) and chalcone synthase (AlCHS) genes were found in grape endophyte Alternaria sp. MG1, but were not functional verified. A cross-validation method was used in Saccharomyces cerevisiae to identify their functions. AlCHS was identified to synthesize both naringenin

The Fabrication of Fragrance Microcapsules and Their Sustained and Broken Release Behavior.

Hongbin Zhao et al.

Materials (Basel, Switzerland), 12(3) (2019-01-30)

Their controlled release property is the most important feature of functional microcapsules and carriers. In this work, melamine resin shell fragrance microcapsules were fabricated in a non-ionic system, and their chemical structure, particle size, and morphology were analyzed. The sustained

Increased glycosidase activities improved the production of wine varietal odorants in mixed fermentation of P. fermentans and high antagonistic S. cerevisiae.

Na Li et al.

Food chemistry, 332, 127426-127426 (2020-07-04)

A selected Pichia fermentans strain was simultaneously and sequentially inoculated in synthetic and real juice with S. cerevisiae strains of different antagonistic activities in a ratio 1:1 to observe the correlation between varietal odorants and glycosidase activities. Fermentations using pure

Functions of duplicated glucosinolate sulfatases in the development and host adaptation of Plutella xylostella.

Wei Chen et al.

Insect biochemistry and molecular biology, 119, 103316-103316 (2020-01-19)

Evolutionary adaptations of herbivorous insects are often dictated by the necessity to withstand a corresponding evolutionary innovation in host plant defense. Glucosinolate sulfatase (GSS) enzyme activity is considered a central adaptation strategy in Plutella xylostella against glucosinolates (GS)-myrosinase defense system
