“…Phytopathogen inhibition by bacteria is generally performed with at least two antagonistic mechanisms, which make it more efficient to control diseases in postharvest fruit [5]. Several modes of anti-phytopathogen action of bacteria have been described [29,30], notably space and nutrient competition, parasitism, volatile compounds, and biofilms, among others ( Figure 1). The main antagonistic mechanisms exerted by bacteria against phytopathogens are described below.…”

“…Proteases can be divided into four main groups according to their site of action, namely, serine proteinases, cysteine proteinases, aspartic proteinases, and metaloproteinases [54]. During the last decade, different research studies have been performed on hydrolytic enzymes that produce bacteria and yeasts [29]. The genera Bacillus and Pseudomonas are considered as some of the most efficient antagonists in phytopathogen control due to the direct action of chitinase [55].…”

“…Induction of resistance is the capacity of an antagonistic bacterium to provoke defense response in the host through several chemical or biochemical reactions, including changes in tissue structure and protein production related to pathogenesis, expressed either locally or systemically [29]. Induction of resistance in fruit by bacteria, as BCA, has been considered a mode of action to control postharvest diseases [32,77].…”

“…Several antagonistic microorganisms have been recommended to be used in fields before harvest with the purpose of protecting postharvest cultivation [7,29]. Lopes et al [110] assessed the efficacy of different antagonistic microorganisms in controlling Colletotrichum acutatum with applications on preharvest citrus fruit and found promising results.…”

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

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.
