“…albidus Bo86, P. kudriavzevii Bo91, P. kudriavzevii Bo108, W. anomalus Bo107 and W. anomalus Bo156 were isolated from olive environments, mainly from the fruit surface. Our results agree with other findings that showed that P. kudriavzevii (Issatchenkia orientalis) and W. anomalus were antagonists of anthracnose caused by Colletotrichum species in other crops (Campos-Martínez et al, 2016;Chanchaivovat et al, 2007;Chi et al, 2015;Lima et al 2013). Our study is the first that reports the use of P. kudriavzevii and W. anomalus as biocontrol agents against C. gloeosporioides in olive fruits.…”

Antifungal activity of native yeasts from different microenvironments against Colletotrichum gloeosporioides on ripe olive fruits

Anthracnose is a fungal disease caused by Colletotrichum species, which mainly affects olive fruits during ripening. The use of yeasts from related and unrelated microenvironments in the control of plant pathogens has become an alternative to the use of synthetic fungicides. The objectives of the present study were to evaluate in vitro biocontrol strategies against C. gloeosporioides, in order to select native antagonistic yeasts isolated from different microenvironments, and to verify the in vivo biocontrol activity on ripe olive fruits. The potential human pathogenicity of the antagonistic yeasts was also considered. A total of 241 wild yeasts from diverse olive cultures and vitivinicultural microenvironments were assayed in vitro and in vivo for their antagonistic effect against the pathogen C. gloeosporioides. Ninety-two yeasts with in vitro characteristics of competitiveness such as niche overlap, dominance against the pathogen, reduction of fungal growth and production of antifungal metabolites were examined on ripe olive fruits. Nine biocontrol yeasts, three from fermenting grape must and six from olive fruits, leaves and branches in vivo reduced the incidence and severity of C. gloeosporioides. According to the 42°C test, which assays for pseudohyphal formation and phospholipase production, these biocontrol yeasts did not present a health risk to humans. Microenvironments with selective stress factors can be relevant sources of microorganisms with biocontrol purposes.

“…Meyerozyma guilliermondii reduced the fungal hyphal growth of C. gloeosporioides, the cause of anthracnose on papaya [34]. Wickerhamomyces anomalus isolated from avocado leaves showed in vitro antagonistic activity against C. gloeosporioides, the cause of anthracnose on avocado [35]. Among four antagonistic yeast strains, T. indica DMKU-RP31 and T. indica DMKU-RP35 revealed the ability to inhibit plant pathogens' cause of rice diseases, namely Curvularia lunata (cause of dirty panicle disease), Fusarium moniliforme (cause of bakanae disease), Helminthosporium oryzae (cause of brown spot disease), Rhizoctonia solani (cause of sheath blight disease) and Pyricularia oryzae (cause of blast disease) (data not showed).…”

Biological Control of Fruit Rot and Anthracnose of Postharvest Mango by Antagonistic Yeasts from Economic Crops Leaves

2020

To select antagonistic yeasts for the control of fruit rot caused by Lasiodiplodia theobromae and anthracnose caused by Colletotrichum gloeosporioides in postharvest mango fruit, 307 yeast strains isolated from plant leaves were evaluated for their antagonistic activities against these two fungal pathogens in vitro. Torulaspora indica DMKU-RP31, T. indica DMKU-RP35 and Pseudozyma hubeiensis YE-21 were found to inhibit the growth of L. theobromae whereas only Papiliotrema aspenensis DMKU-SP67 inhibited the growth of C. gloeosporioides. Antagonistic mechanisms of these four antagonistic yeasts in vitro consisted of the production of antifungal volatile organic compounds (VOCs), biofilm formation and siderophore production. T. indica DMKU-RP35 was the most effective strain in controlling fruit rot on postharvest mango fruits. Its action was comparable to that of the fungicide, benomyl, reducing the disease severity by 82.4%, whereas benomyl revealed 87.5% reduction. P. aspenensis DMKU-SP67 reduced anthracnose severity by 94.1%, which was comparable to that of using benomyl (93.9%). The antifungal VOCs produced by these yeast strains also reduced the severity of these diseases on postharvest mango fruits but at lower rates than using yeast cells. Therefore, these antagonistic yeasts have the potential for use as biological control agents for the control of fruit rot and anthracnose diseases.

“…The yeast strains had been previously shown in vitro antagonistic activity against C. gloeosporioides [69]. Various Bacillus spp., which were originally isolated from leaf and fruit surfaces of avocados, were also observed to effectively control anthracnose of avocado [70,71].…”

Extension of Avocado Fruit Postharvest Quality Using Non-Chemical Treatments

2020

View full text Add to dashboard Cite

Developing postharvest management techniques using environmentally friendly and non-chemical approaches is key to extending the shelf life of avocados in a safer and health conscious manner. Avocados are prone to postharvest deterioration caused by mechanical damage, chilling injury, soft landing, uneven ripening and decay. Among the different cultivars of avocados commercially grown worldwide, the ‘Hass’ variety continues to be the most predominant due to its nutty flavour and functional properties. Most of the literature on postharvest decay and disorders affecting avocado fruit quality during storage and marketing is dedicated to the Hass avocado. Some of these postharvest problems are unique to the ‘Hass’ avocado can possibly be controlled by simply investing more research into other cultivars. These postharvest losses can be significantly controlled using eco-friendly technologies, such as modified atmosphere, physical heat treatments and most importantly investing in natural biodegradable products with naturally inherent antimicrobial properties. Thus, this review includes the recent research-based information on the use of non-chemical treatments on the improvement of fruit health and quality.
