“…This yeast is in the Basidiomycota clade and belongs to the Tremellaceae family, in the order Tremellales. Saitozyma podzolica showed biological control ability against post-harvest pathogens in apples, such as Penicillium expansum (Wang et al, 2018). This indicated that the fungus could have the ability to prevail in soil over other fungal species.…”

Massive sequencing of fungal communities showed that climatic factors, followed by edaphic and spatial variables, are feasible predictors of fungal richness and community composition. This study, based on a long-term field experiment with tillage and no-tillage management since 1995 and with a crop rotation introduced in 2009, confirmed that tillage practices shape soil properties and impact soil fungal communities. Results highlighted higher biodiversity of saprotrophic fungi in soil sites with low disturbance and an inverse correlation between the biodiversity of ectomycorrhizal and saprotrophic fungi. We speculated how their mutual exclusion could be due to a substrate-mediated niche partitioning or by space segregation. Moreover, where the soil was ploughed, the species were evenly distributed. There was higher spatial variability in the absence of ploughing, with fungal taxa distributed according to a small-scale pattern, corresponding to micro-niches that probably remained undisturbed and heterogeneously distributed. Many differentially represented OTUs in all the conditions investigated were unidentified species or OTUs matching at high taxa level (i.e., phylum, class, order). Among the fungi with key roles in all the investigated conditions, there were several yeast species known to have pronounced endemism in soil and are also largely unidentified. In addition to yeasts, other fungal species emerged as either indicator of a kind of management or as strongly associated with a specific condition. Plant residues played a substantial role in defining the assortment of species.

“…Compared to simple treatment with microbial agents, integrated approaches have, for example, given better results against P. expansum infection and PAT accumulation in fruits, such as the combination of Pichia caribbica with bamboo leaf flavonoids (Mahunu et al., 2018) showed better results. Similarly, Rhodotorula mucilaginosa with phytic acid (Mahunu et al., 2016; Yang et al., 2015); Cryptococcus podzolicus with β‐glucans (Wang et al., 2018); Sporidiobolus pararoseus Y16 with active Baobab extract (Abdelhai et al., 2019), and Pichia caribbica with betaine wisteria (Zhang et al., 2017) have been proved as potential integrated approaches in various fruits and against various pathogens. These bioenhancers improved the lignin content of the apple wound, which certainly restricted the penetration of pathogenic fungi during infection of fruits (Mahunu et al., 2018).…”

Fruit‐based diets have been adopted by the public worldwide because of their nutritional value. Many advances have also been made in the elucidation of host–pathogen interaction in the postharvest phase of fruits, in the hope of improving the management of diseases caused by pathogenic molds. In this study, we presented the molecular mechanisms by which pathogenic mold infects fruit in the postharvest phase, and focused on the knowledge gained from recent molecular techniques such as differential analysis of gene expression, targeted insertion, and mutagenesis. Current postharvest pathogenic fungal control strategies were then examined on the basis of their mechanisms for altering the infection process in order to explore new perspectives for securing fruit production. We found that biotechnological advances have led to an understanding of the new basic molecular processes involved in fruit fungal infection and to the identification of new genes, proteins and key factors that could serve as ideal targets for innovative antifungal strategies. In addition, the most commonly used steps to evaluate an approach to disrupt the fruit fungal infection process are mainly based on the inhibition of mycelial growth, spore germination, disruption of Adenosine triphosphate (ATP) synthesis, induction of oxidative stress, cell wall membrane damage, and inhibition of key enzymes. Finally, the alteration of the molecular mechanisms of signaling and response pathways to infection stimulation should also guide the development of effective control strategies to ensure fruit production.

“…The β‐glucans are well known to exhibit some interesting antioxidant activities. Therefore, we combined β‐glucans with an antagonist yeast named Cryptococcus podzolicus and showed an increased capacity of C. podzolicus biocontrol against PAT‐producing molds (Wang et al., 2018). Treatment of apples with C. podzolicus (1 × 10 8 cells/mL) grown in NYDB supplemented with 0.5% β‐glucan produced a disease incidence of only 40.8% while that of CK was 100% ( p < 0.05).…”

“…When enriched with β‐glucan, C. podzolicus grows best in the apple wounds at 20 or 4°C. In the apples tested, the defensive activities of peroxidase, catalase, and polyphenol oxidase increased (Wang et al., 2018). The use of antifungal biomolecules with some antioxidant properties gave more information about the role of oxidative burst (release of a large quantity of reactive oxygen species [ROS]) at the wound level following the colonization of antagonistic cells.…”

Patulin (PAT) is a mycotoxin that can contaminate many foods and especially fruits and fruit‐based products. Therefore, accurate and effective testing is necessary to enable producers to comply with regulations and promote food safety. Traditional approaches involving the use of chemical compounds or physical treatments in food have provided practical methods that have been used to date. However, growing concerns about environmental and health problems associated with these approaches call for new alternatives. In contrast, recent advances in biotechnology have revolutionized the understanding of living organisms and brought more effective biological tools. This review, therefore, focuses on the study of biotechnology approaches for the detection, control, and mitigation of PAT in food. Future aspects of biotechnology development to overcome the food safety problem posed by PAT were also examined. We find that biotechnology advances offer novel, more effective, and environmental friendly approaches for the control and elimination of PAT in food compared to traditional methods. Biosensors represent the future of PAT detection and use biological tools such as aptamer, enzyme, and antibody. PAT prevention strategies include microbial biocontrol, the use of antifungal biomolecules, and the use of microorganisms in combination with antifungal molecules. PAT detoxification aims at the breakdown and removal of PAT in food by using enzymes, microorganisms, and various adsorbent biopolymers. Finally, biotechnology advances will be dependent on the understanding of fundamental biology of living organisms regarding PAT synthesis and resistance mechanisms.
