Abstract

Colletotrichum gloeosporioides (C. gloeosporioides) is widely distributed pathogen responsible for postharvest losses in fruits and vegetables. Black pepper essential oil (BPEO) has emerged as natural antifungal agent that effectively inhibits C. gloeosporioides growth. However, the precise mechanism remains incompletely understood. This research investigates the suppressive properties of BPEO nanoemulsion on C. gloeosporioides and its impact on the respiratory metabolism. Results indicated that 2 MIC BPEO nanoemulsion have the best antifungal effect. Mechanistically, 2 MIC BPEO nanoemulsion can better suppress key enzymes connected to the Tricarboxylic Acid (TCA) cycle and Embden-Meyerhof-Parnas (EMP) pathway, hence reducing the C. gloeosporioides respiration rate. The total respiratory rate decreased by 60.54%, after 2 MIC BPEO nanoemulsion treatment. In conclusion, the BPEO nanoemulsion effectively mitigates fungal proliferation and reproduction by downregulating relevant enzymes expression. However, it is necessary to further expand the research on the regulation mechanism of enzyme activity at gene and protein level.

期刊介绍： The FSB journal covers food chemistry and analysis for compositional and physiological activity changes, food hygiene and toxicology, food microbiology and biotechnology, and food engineering involved in during and after food processing through physical, chemical, and biological ways. Consumer perception and sensory evaluation on processed foods are accepted only when they are relevant to the laboratory research work. As a general rule, manuscripts dealing with analysis and efficacy of extracts from natural resources prior to the processing or without any related food processing may not be considered within the scope of the journal. The FSB journal does not deal with only local interest and a lack of significant scientific merit. The main scope of our journal is seeking for human health and wellness through constructive works and new findings in food science and biotechnology field.
