Biocontrol activity of the marine yeast Debaryomyces hansenii against phytopathogenic fungi and its ability to inhibit mycotoxins production in maize grain (Zea mays L.)

Use of a marine yeast as a biocontrol agent of the novel pathogen Penicillium citrinum on Persian lime

“…In these sense, the use of adjuvants like Tween 80 (as surfactant) or dextrose (as nutrient) could be an alternative to a better distribution and maintaining of antagonistic yeast population on carposphere at concentrations suitable for biological control, as previously reported (De Cal et al, 2012;Spadaro and Droby, 2016 (Chalutz and Wilson, 1990;Droby et al, 1999;Taqarort et al, 2008). In a recent study marine D. hansenii was capable to inhibit the mycelial growth of pathogenic fungi of maize (Zea mays L.) (Medina-Córdova et al, 2016). The mechanisms of action reported to D. hansenii are related to competition for nutrients and space, parasitism, production of cell-wall lytic enzymes, induction of host resistance and recently the production of extracellular soluble and volatile compounds (Droby et al, 2002;Hernández-Montiel et al, 2010a;Medina-Córdova et al, 2016).…”

Then the aim of this study was to evaluate the potential of D. hansenii with and without adjuvants in the control of P. citrinum in Persian lime.…”

Biocontrol Potential of Fungal Endophytes against Fusarium oxysporum f. sp. cucumerinum Causing Wilt in Cucumber

“…Tenday-old cultures of endophyte killed P. ultimum in vitro (Worapong and Strobel, 2009). Moreover, the recent study indicated that when Debaryomyces hansenii was tested against four strains of pathogenic fungi, the results showed that it decreased the mycelia colony growth of the four pathogenic fungi such as Aspergillus sp., Fusarium proliferatum , and F. subglutinans from 97–98.3% by producing volatile compounds (Medina-Córdova et al, 2016). In addition when T. harzianum and S. proteamaculans were screened against Rhizoctonia solani , both endophytic fungi were highly effective to reduce the growth of pathogen in in vitro by overgrown the pathogen mycelia growth (Youssef et al, 2016), likewise, when Beauveria sp.…”

Occurrence and preventive strategies to control mycotoxins in cereal‐based food

“…For example, the level of AFs was reduced appreciably in artificially contaminated wheat flour by introducing LAB culture during breadmaking process (Saladino, Luz, Manyes, Fernández‐Franzón, & Meca, 2016). Regarding the yeast, two strain of yeasts including Saccharomyces cerevisiae and Debaryomyces hansenii exhibited antifungal, and mycotoxins inhibitory activities (e.g., OTA and FBs) in vitro studies (Medina‐Córdova et al., 2016; Petruzzi et al., 2013). Some preharvest beneficial fungi are also found to be effective in inhibition of mycotoxigenic fungi growth (Sarrocco & Vannacci, 2018).…”
