“…PPO activity changes the disease resistance of fruits and vegetables, which is closely related to the direct role of pathogens, and PPO also plays a protective role in the plant. CAT, which is known to control reactive oxygen scavengers (ROS) [23], was described as the capacity of the tissues to scavenge excess ROS and maintain ROS concentration at relatively low level [1]. Our results suggested that the CAT activity of apples was induced by S. pararoseus Y16 in this study; S. pararoseus Y16 improved CAT activity of apples, which may also be one of the reasons for enhancing the resistance ability of apples [24].…”

The efficacy of Sporidiobolus pararoseus Y16 in controlling postharvest blue mold caused by Penicillium expansum on apples and the defense response involved were evaluated. The results suggested that the decay incidence of blue mold of apples treated by S. pararoseus Y16 was significantly reduced compared with the control. In vitro testing indicated that germination of spores and germ tube length of P. expansum were markedly inhibited by S. pararoseus Y16. Meanwhile, polyphenol oxidase (PPO), peroxidase (POD), phenylalanine ammonia lyase (PAL), and catalase (CAT) activities and several pathogenesis-related (PR) gene expression levels (including PR3, PR4, PR5, and PR9) were determined. In apples, the activities of PPO, POD, CAT, and PAL were significantly induced by S. pararoseus Y16 treatment compared with the control fruits. The relative expression levels of PR3 and PR4 were significantly induced at 4 and 6 d, while PR5 was significantly induced at 4 and 6 d and PR9 was significantly induced at 4 d. Therefore, the reduction in apple fruit decay by S. pararoseus Y16 treatment could be related to the increased activities of related enzymes and proteins involved in the defense against pathogens, which suggest that S. pararoseus Y16 is a potential antagonistic yeast.

“…The combination of antagonists with other antimicrobial compounds could be an efficient method to improve the yield of BC. Combination with salts, such as bicarbonates, and natural compounds, such as chitosan, have improved the yield of BCA [113].…”

Biocontrol of Postharvest Fruit Fungal Diseases by Bacterial Antagonists: A Review

et al. 2019

This review deals with the main mechanisms of action exerted by antagonistic bacteria, such as competition for space and nutrients, suppression via siderophores, hydrolytic enzymes, antibiosis, biofilm formation, and induction of plant resistance. These mechanisms inhibit phytopathogen growth that affects postharvest fruit since quality and safety parameters are influenced by the action of these microorganisms, which cause production losses in more than 50% of fruit tree species. The use of synthetic fungicide products has been the dominant control strategy for diseases caused by fungi. However, their excessive and inappropriate use in intensive agriculture has brought about problems that have led to environmental contamination, considerable residues in agricultural products, and phytopathogen resistance. Thus, there is a need to generate alternatives that are safe, ecological, and economically viable to face this problem. Phytopathogen inhibition in fruit utilizing antagonist microorganisms has been recognized as a type of biological control (BC), which could represent a viable and environmentally safe alternative to synthetic fungicides. Despite the ecological benefit that derives from the use of controllers and biological control agents (BCA) at a commercial level, their application and efficient use has been minimal at a global level.

“…For these reasons, the performance of biological-based control strategies in the field is subject to significant variability which constitutes a significant constraint to their practical implementation (Droby et al, 2009;Wisniewski et al, 2007). In these sense, different approaches have been reported to make the BCAs more efficient: the use of mixed cultures (Conway, Janisiewicz, Leverentz, Saftner & Camp, 2007;Panebianco, Vitale, Polizzi, Scala & Cirvilleri, 2016), their physiological manipulation (Usall et al, 2009;Wang, He, Xia, Yu & Zheng, 2014) and their combination with different types of substances (Guo et al, 2014;Qin et al, 2015;Zhou et al, 2016). The application of BCAs in combination with coating materials has been reported to enhance the BCA effectiveness at inhibiting the growth of plant pathogens, as discussed in the next section.…”

The in-field performance of microbial biocontrol agents against fungal pathogens in fruit is subject to considerable variability due to their sensitivity to both adverse environmental conditions and their fluctuations. Therefore, to achieve an adequate development and implementation of biological agent-based products, it is necessary to improve their resistance and ability to control fungal diseases under a wide range of conditions. In this review, an overview of the latest strategies for the enhancement of the action of biocontrol agents is given. The combination of the antagonists with edible polymers able to form coatings is one of the approaches with the greatest potential and it is analysed in depth. This formulation approach of biocontrol products, including adequate microbial protectants, can yield stable products with high microbial viability, ready for field applications, with improved adherence and survival of the biocontrol agent once applied in plant. The most recent studies into this field are reviewed and summarized.
