“…The presence of Cladosporium indicated that inoculation of LAB showed a limited effect on the stability of silage at the final stage of ensiling. Genera of Rhizopus occurred rarely in silages ( Rodríguez-Blanco et al, 2021 ). It was first reported that Buckleyzyma salicina distributed in timothy silage.…”

This study investigated the effects of phenyllactic acid (PL), lactic acid bacteria (LAB), and their mixture on fermentation characteristics and microbial community composition of timothy silage. Timothy silages were treated without (CK) or with PL [10 mg/kg fresh matter (FM) basis], LAB inoculant (IN; a mixture of Lactobacillus plantarum and L.buchneri, 105 cfu/g FM), and their mixture (PI) and stored at ambient temperature (5°C∼15°C) in a dark room for 60 days. Compared with CK, all treated silages showed lower (P < 0.05) levels of butyric acid and ammonia-N. Treatment with PL enhanced (P < 0.05) the crude protein preservation of silage by favoring the growth of L. curvatus and Saccharomyces cerevisiae and inhibition of lactic acid–assimilating yeast belonging to Issatchenkia during ensiling. In particular, treatment with PL advanced (P < 0.05) the productions of lactic acid and volatile fatty acid in IN-treated silage. Therefore, PL used as a new additive exhibited potential for improving silage fermentation when it is combined with LAB IN during ensiling.

“…FBs production is stimulated by certain environmental conditions: maximum accumulation of FBs by F . verticillioides in maize usually occurs between 20 and 25°C, and favourable a w levels are established between 0.95 and 0.99 (Marín et al, 2004; Mogensen et al, 2009; Yu et al, 2021), which are situations that can be commonly found during maize silage (Rodríguez‐Blanco et al, 2021). It is under these advantageous conditions that the antifungals should present outstanding FBs diminishing effects.…”

Aims To minimize fumonisins (FBs) accumulation by Fusarium verticillioides in post‐harvest maize, using flavonoids obtained from citrus residues: naringin (NAR), neohesperidin (NEO), quercetin (QUER), and its mixtures. Methods and Results Response surface methodology with Box‐Behnken design was applied in maize at 0.98 and 0.95 aw. The optimal mixture found, composed of 0.40 mmol kg−1 NAR, 0.16 mmol kg−1 NEO and 0.37 mmol kg−1 QUER, reduced the accumulation of FBs B1, B2, and B3 by 88 ± 6%, 90 ± 6% and 85 ± 5%, respectively, when applied to maize at 0.98 aw. The mentioned mixture led to a 54 ± 9% reduction of fumonisin B1 accumulation in maize adjusted to 0.95 aw. These flavonoids applied individually and as a mixture, affected the structure of both the cell wall and the cytoplasm of F. verticillioides. The cell wall lost rigidity and the cells appeared highly deformed, with ruptured plasmalemma and disrupted endomembranes. Conclusions It was possible to diminish the accumulation of FBs in maize by a highly toxigenic Fusarium strain, producing severe damage to its ultrastructure. Significance and Impact of Study The results indicate the possible use of flavonoids from citrus industry residues as natural and environmentally friendly antifungal agents to restrain the accumulation of FBs in stored maize.

“…Despite the mitigation efforts, exposure of crops to mycotoxins is indeed inevitable and decontamination is very difficult [ 3 , 4 ]. Even though numerous studies concerning the effect of mycotoxins are reported in the specific literature, the contamination of cereals with fusariotoxins, the impact on animal health and the economic losses they imply [ 5 , 6 , 7 ], the transmission of fusariotoxins into the target organism and the potential existence of toxic components in meat and dairy products remain unknown and need further investigations [ 8 ].…”

Zearalenone (ZEA) is an estrogenic fusariotoxin, being classified as a phytoestrogen, or as a mycoestrogen. ZEA and its metabolites are able to bind to estrogen receptors, 17β-estradiol specific receptors, leading to reproductive disorders which include low fertility, abnormal fetal development, reduced litter size and modification at the level of reproductive hormones especially in female pigs. ZEA has also significant effects on immune response with immunostimulatory or immunosuppressive results. This review presents the effects of ZEA and its derivatives on all levels of the immune response such as innate immunity with its principal component inflammatory response as well as the acquired immunity with two components, humoral and cellular immune response. The mechanisms involved by ZEA in triggering its effects are addressed. The review cited more than 150 publications and discuss the results obtained from in vitro and in vivo experiments exploring the immunotoxicity produced by ZEA on different type of immune cells (phagocytes related to innate immunity and lymphocytes related to acquired immunity) as well as on immune organs. The review indicates that despite the increasing number of studies analyzing the mechanisms used by ZEA to modulate the immune response the available data are unsubstantial and needs further works.
