Bacteria are frequently identified by fatty acid analysis. We previously reported on methods to speed up sample preparation and gas chromatography, resulting in greatly improved speed and throughput [J. Microbiol. Methods 51 (2002) 209]. In this paper, we demonstrate that further reductions in chromatographic retention times are readily achieved, leading to faster identification of bacteria.

Macrocyclic polymer materials exhibit excellent selectivity and adsorption performance in pollutant adsorption due to unique host-guest recognition. Herein, three kinds of calixarene polymers (C4P, C6P and C8P) were synthesized through Sonogashira reaction, and were characterized through H NMR, FT-IR, SEM, and TEM. The water contact angle experiments revealed that three kinds of calixarene polymers were highly hydrophobic, and they all exhibited high enrichment efficiency for weak polar chloro-substituted benzene compounds (chlorobenzene, o-chlorotoluene, p-dichlorobenzene and o-dichlorobenzene) and BTEX (benzene, toluene, ethylbenzene and xylenes).

The genus Euphorbia, belonging to the family Euphorbiaceae, represents a significant ethnobotanical heritage due to the diverse bioactive properties exhibited. In this study, the phytochemical composition and biological activities of latex and aerial parts of the water extract of Euphorbia gaillardotii were investigated. Phytochemical analyses were performed using gas chromatography-mass spectrometry and high-performance liquid chromatography techniques and total antioxidants, phenolics, sugars, organic acids, and aroma components were quantitatively determined.

Objectives: To investigate the phytochemical composition of Ajwa date extract and evaluate its antiviral activity and mechanism of action.
Methods: High perfomance liquid chromatography, gas chromatography-mass spectrometry, and liquid chromatography-mass spectrometry were used to analyze the phytochemical profile of Ajwa date extract. The antiviral activity was assessed using the MTT colorimetric assay against herpes simplex virus type I (HSV-I) and coxsackievirus B4 (CVB-4).

This study evaluated the impact of fermentation with Lactobacillus acidophilus pre-subjected to acid, osmotic, and oxidative stress conditions on the production of metabolites and the bioaccessibility of nutrients and bioactive compounds in fermented milks and yogurts. The products were added with orange bagasse (additional calcium - Ca source) and buriti pulp (carotenoids source). Gas chromatography coupled with mass spectrometry (GC-MS) and nuclear magnetic resonance (NMR) were used to analyze the volatile and non-volatile compounds metabolites from fermentation, respectively.
