“…PPO is also associated with induced defense response in fruit. It can oxidize phenols to quinines, which are highly toxic to pathogens, and involves in the synthesis of lignin and the thickening of the cell wall to oppose pathogen intrusion and proliferation (Duan, Yang, & Tao, ). However, in this study, the PPO activity was higher in the untreated control fruit, but low and nonsignificant between the treatments.…”

There is a growing interest in using natural antifungal compounds for the preservation of foods. The first experiment of this study was investigated an effect of pomegranate peel extract (PPE) and the essential oil (PPEO) in different concentrations mixed with potato dextrose agar (PDA) on spore germination of Penicillum italicum and Penicillum digitatum. in vivo experiments were focused on the treatments offering potential antifungal and antioxidant benefits. Preventive treatments were performed by dipping wounded fruit into the specific concentrations of extract and thereafter, each wound site was infected by inoculating 20 μL of the inoculum of P. italicum or P. digitatum. For curative treatments, fruit were wounded as above, and then inoculated with P. italicum or P. digitatum. Even though data showed no significant differences between PPEO treatments, PPE at 100 and 125 ppm elicited significantly lower spore germination under in vitro conditions compared to the other treatments. The results showed that 75% or/and 100% PPE reduced infected wound percentage and lesion diameter and increased total phenolic, flavonoid compounds content, and phenylalanine ammonia‐lyase activity in “Satsuma” mandarin rind. The tested PPE can be effectively utilized for controlling and curing infections caused by P. italicum and P. digitatum. Practical applications The results obtained in this research could be advantageously used by industry as a request of consumer demand for pesticide‐free food. The results indicate that it is possible to substitute the synthetic compounds with preservatives safer for man and environment.

“…3,4 Furthermore, the ability of these molds to produce countless airborne spores allows them to spread wherever citrus fruits are handled, including in fields, equipment, transit containers, storage rooms, packing houses and marketplaces. 5,6 Green mold develops more rapidly than blue mold under ambient conditions, and conversely, P. italicum grows faster than P. digitatum at low temperatures. As a result, blue mold becomes a more serious problem when citrus fruits are kept for long periods in cold storage.…”

BACKGROUND The application of chemical fungicides is currently the main method for the control of postharvest decay of fruits and vegetables. However, public concern has been growing towards the effect of fungicides on food safety, human health and environmental pollution. Thus, interest in microbial biocontrol agent development has grown, such agents being considered both safe and environmentally friendly. Pseudomonas fluorescens is widely distributed in nature, and one of the most valuable biocontrol and plant growth‐promoting rhizobacteria. In this study, the efficacy and the potential associated modes of action of P. fluorescens ZX against Penicillium italicum on oranges (Citrus sinensis Osbeck) were investigated. RESULTS The application of P. fluorescens ZX significantly reduced blue mold lesion size and incidence in comparison to the control, where P. fluorescens ZX was effective when applied preventatively but not curatively. In dual cultures, treatment with cell‐free autoclaved cultures or culture filtrate had a limited capacity to suppress P. italicum, while P. italicum was inhibited by bacterial fluid and bacterial suspension with living cells in vitro. The P. fluorescens ZX isolate displayed protease, but not chitinase, glucanase or cellulose, activity, and produced siderophores and volatile organic compounds with antifungal abilities. Competition tests showed P. fluorescens ZX could use fructose, sucrose, aspartic acid, threonine, serine, glycine, valine, lysine and proline better than P. italicum. Furthermore, an effective biofilm that peaked after a 24‐hour incubation at 30 °C was formed by the P. fluorescens ZX isolate. Light microscopy and scanning electron microscopy observations indicate the P. fluorescens ZX isolate could not undergo direct parasitism or hyperparasitism. CONCLUSIONS Competition for nutrients and niches, biofilm formation, inhibition of spore germination and mycelial growth, and production of inhibitory metabolites may play important roles in P. fluorescens ZX antagonism of P. italicum. © 2019 Society of Chemical Industry
