Black spot disease, which is caused by the pathogenic fungal Ceratocystis fimbriata, seriously affects the production of sweet potato and its quality during postharvest storage. In this study, the preliminary identification of the rhizosphere actinomycete strain SPS-33, and its antifungal
Muscodor albus (Xylariaceae, Ascomycetes) isolate CZ-620 produces antimicrobial volatile organic compounds (VOC), which appear to have potential for the control of various postharvest diseases. The effect of water activity (Aw) on the production of VOC by M. albus culture, and their inhibitory
We tested the ability of 14 strains of Trichoderma to emit volatile compounds that decreased or stopped the growth of Phytophthora infestans. Volatile organic compounds (VOCs) emitted from Trichoderma strains designated T41 and T45 inhibited the mycelial growth of P.
Over the past two decades, whole-cell biosensors (WCBs) have been widely used in the environmental field, with only few applications proposed for use in agricultural. This study describes the development and optimization of a WCB for the detection of volatile organic compounds (VOCs) that is
Several microbial volatile organic compounds (MVOCs) that can serve as potential chemical markers for microbial contamination in tobacco have been identified. Four different fungal species, Aspergillus niger (AN), A. ornatus (AO), Pencillium chrysogenum (PC) and Rhizopus stolonifer (RS), commonly
Two types of Chinese soy sauce, high-salt liquid-state fermentation soy sauce (HLFSS) and low-salt solid-state fermentation soy sauce (LSFSS), were used to investigate their differences in aroma profile by headspace solid-phase microextraction (HS-SPME) and gas chromatography-olfactometry/mass
Volatile compounds produced by Pseudomonas perolens ATCC 10757 in sterile fish muscle (Sebastes melanops) were identified by combined gas-liquid chromatography and mass spectrometry. Compounds positively identified included methyl mercaptan, dimethyl disulfide, dimethyl trisulfide,
In this study, the antimicrobial potential of three fungal endophytes from leaves of Olea europaea L. was evaluated and the host plant extract effect in the antimicrobial activity was examined. The volatile compounds produced by endophytes were identified by GC/MS and further correlated with the
The biocontrol activity and chemical composition of the volatile organic compounds (VOCs) produced by Pseudomonas chlororaphis subsp. aureofaciens SPS-41 were investigated. The VOCs inhibited mycelial growth and spore germination in Ceratocystis fimbriata, which causes black rot disease in sweet
The key odorants in the volatile fraction isolated from a steamed yeasted wheat dough (yeast dumpling) by solvent assisted flavor evaporation (SAFE) were characterized by an aroma extract dilution analysis (AEDA). The 29 aroma-active compounds were located within the flavor dilution (FD) factor
Volatile compounds in cold smoked salmon products were identified by gas chromatography to study their suitability for rapid detection as indicators to predict sensory quality evaluated by quantitative descriptive analysis. Smoked salmon odour contributed by guaiacol, boiled potato- and
