摘要

Certain microbial Volatile Organic Compounds (VOCs) have been reported to enhance the growth and development of plants. The biocontrol fungi, Cladosporium cladosporioides CL-1 significantly improved the growth of tobacco seedlings in vitro when they were co-cultivated without physical contact. SPME Quadrupole GC/MS/MS revealed that CL-1 emited the volatiles -pinene, (-)-trans-caryophyllene, tetrahydro-2,2,5,5-tetramethylfuran, dehydroaromadendrene, and (+)-sativene. Potential roles of these volatiles in plant growth and development are discussed. Even though there were several fungal VOCs reported in the past that could influence plant growth, their exact mechanisms of action are not fully known. Fungal VOC-mediated plant growth promotion requires in-depth study in order for this technology to be used in large scale for crops, especially those grown under greenhouse conditions.

Volatile Compound Characterization of Coffee (Coffea arabica) Processed at Different Fermentation Times Using SPME-GC-MS

Gustavo Galarza, Jorge G. Figueroa

Summary: This investigation examined the relationship between different dry fermentation processes of coffee (aerobic, anaerobic, and CO2 modified atmosphere) and fermentation times, in relation to pH, acidity, and seven volatile marker compounds. The results showed that fermentation time had a significant effect on pH and acidity. The presence of acetic acid was positively correlated with fermentation time, while other compounds showed negative correlation. The different fermentation treatments had varying affinities with the volatile marker compounds analyzed.

Volatile organic compounds involved in the communication of microalgae-bacterial association extracted through Headspace-Solid phase microextraction and confirmed using gas chromatography-mass spectrophotometry

Madhubalaji Chegukrishnamurthi, Ajam Shekh, Sarada Ravi, Sandeep Narayana Mudliar

Summary: In this study, the production of volatile organic compounds (VOCs) and their effect on growth were investigated by cultivating bacterial mixture (Rhizobium and Agrobacterium) and axenic Chlorella individually, in a mixed form, and through headspace connections. The results showed significant differences in VOCs produced by axenic Chlorella and Chlorella co-cultured with bacteria. The growth of co-cultured Chlorella was greatly enhanced, indicating the essential role of VOCs in growth and communication.

Screening of volatile decay markers of minced pork by headspace-solid phase microextraction-gas chromatography-mass spectrometry and chemometrics

Xuechao Song, Elena Canellas, Cristina Nerin

Summary: Headspace solid-phase microextraction coupled with gas chromatography-mass spectrometry (HSSPME-GC-MS) was used to analyze volatile compounds in minced pork meat during storage, with the origin of aromatic hydrocarbons in pork being verified by a migration test. Principal component analysis (PCA) and orthogonal partial least squares discriminant analysis (OPLS-DA) were utilized to characterize the profile of volatile compounds and identify potential volatile markers associated with pork spoilage. Three compounds were identified as additional indicators for quality control of pork based on their importance in discrimination of pork with different storage times.

Summary: Predicting the dying process of advanced cancer patients is challenging. However, by analyzing the changes in volatile organic compounds (VOCs) in urine, it is possible to predict the dying process of patients with lung cancer. Specific changes in VOCs were identified and a prediction model using 8 VOCs showed promising results in stratifying patients into different risk groups.

Characterization of the Aroma Profile of Commercial Prosecco Sparkling Wines

Davide Slaghenaufi, Giovanni Luzzini, Matteo Borgato, Anita Boscaini, Andrea Dal Cin, Vittorio Zandona, Maurizio Ugliano

Summary: This study aimed to analyze the aromatic characteristics of commercially available Prosecco wines within the price range of 7 to 13 euros. The wines were sourced from different regions, including Valdobbiadene, Asolo, and Treviso. A total of 70 volatile compounds were identified and quantified, with esters playing a major role in the aroma. Differences in compounds between the wine's origin areas were observed, particularly in terms of VSC, esters, and C-6 alcohols. Sensory evaluations indicated the formation of distinct clusters, partially attributed to the wine's origin, with variations in esters and compounds associated with wine aging.

Insights into volatile flavor compound variations and characteristic fingerprints in Longpai soy sauce moromi fermentation via HS-GC-IMS and HS-SPME-GC? GC-ToF-MS

Mouyong Zou, Hongbiao Tang, Xun Chen, Liqiong Guo, Junfang Lin

Summary: The flavor substances in different stages of Longpai soy sauce moromi fermentation were analyzed by HS-GC-IMS combined GC x GC-ToF-MS. A total of 374 VOCs were detected, with alcohols and esters being the most abundant. During the early stage, alcohols and aldehydes were the main flavor compounds. The content of esters, pyrazines, furans, and S-containing compounds improved with continuous fermentation. Cluster and PCA analysis showed that 63 VOCs were regarded as marker VOCs for soy sauce in different fermentation stages. Certain compounds, such as alcohols, 1-butanol, and 3-methyl-2-butenal, provided fruity and mellow aroma in the early stage, while caramel-like, malty, and sweet aroma were enhanced by compounds like 3-methyl-2(5H)-furanone, 3-methylbutanol, methional, and acetyl valeryl in the middle stage. Additionally, furfuryl alcohol, 2(5H)-furanone, methyl cyclopentenolone, and 2-Ethyl-6-methylpyrazine could serve as marker VOCs of matured Longpai soy sauce.
