Aroma results from the interplay of volatile organic compounds (VOCs) and the attributes of microbial-producing aromas are significantly affected by fermentation conditions. Among the VOCs, only a few of them contribute to aroma. Thus, screening and identification of the key VOCs is critical for microbial-producing aroma. The traditional method is based on gas chromatography-olfactometry (GC-O)...

Endophytic microorganisms exist within the living tissues of most plant species. They are most abundant in rainforest plants. Novel endophytes usually have associated with them novel secondary natural products and/or processes. Muscodor is a novel endophytic fungal genus that produces bioactive volatile organic compounds (VOCs). This fungus, as well as its VOCs, has enormous potential for uses ...

AgxO/Ag/TiO2 photoactive thin films were produced by different modes of magnetron sputtering (namely, DCMS and HiPIMS). The spectral microstructural properties the Ag-AgxO/TiO2 studied Diffuse Reflection Spectroscopy (DRS) X-ray Photoemission (XPS). atomic deposition TiO2 Ag in sputtered film TEM. exhibited fast photocatalytic volatile organic compounds (VOCs) degradation bacterial inactivation...

The Industrial Safety and Health Law in Japan established administrative levels for volatile organic compounds (VOCs) in indoor air. In the present study, these 49 VOCs were extracted from the absorbents of commercial active samplers from Sibata Scientific Technology (carbon-bead active sampler), SKC Inc. (Anasorb CSC sorbent tube), and Gastec (bead-shaped activated carbon tube) using carbon di...

Dittrichia viscosa (L.) W. Greuter is a pioneer species belonging to the Compositae family. It is widespread in the Mediterranean basin, where it is considered invasive. It is a source of secondary metabolites, playing an important ecological role. D. viscosa plant extracts showed a phytotoxic activity on several physiological processes of different species. In the current study, the allelopath...

Volatile Organic Compounds (VOCs) are among the most toxic chemicals which are detrimental to humans and environment. There is a significant need of fully satisfactory method for removal of VOCs. There are several methods including physical, chemical and biological treatments available to remove VOCs by either recovery or destruction. The aim of the present study is to summarize the available m...

Plants emit volatile organic compounds (VOCs) that play important roles in their interaction with the environment and have a major impact on atmospheric chemistry. The development of static and dynamic techniques for headspace collection of volatiles in combination with gas chromatography-mass spectrometry analysis has significantly improved our understanding of the biosynthesis and ecology of ...

Plant volatile organic compounds (VOCs) have important roles in plant adaptation to the environment and serve as infochemicals in multitrophic interactions. Global climate change factors, such as increased atmospheric carbon dioxide, ozone and temperature, could alter how insects perceive such compounds. Here we review recent research on the influence of climate change parameters on the ecologi...

OBJECTIVES/HYPOTHESIS Electronic noses can identify diseases, including head and neck squamous cell carcinoma (SCC) by the fingerprint of volatile organic compounds (VOCs) in exhaled air. However, whether these VOCs originated from the malignant lesion itself remains unclear. The objective was to test for the presence and properties of VOCs directly over the vocal folds in malignant and benign ...

Abstract The BNT162b2 mRNA vaccine is highly effective against SARS-CoV-2. However, apprehension exists that variants of concern (VOCs) may evade protection, due to evidence reduced neutralization the VOCs B.1.1.7 and B.1.351 by sera in laboratory assays. We performed a matched cohort study examine distribution infections vaccinees from Clalit Health Services (Israel) using viral genomic sequen...
