“…The Penicillium genus is known to produce bioactive molecules with a strong antifungal effect [54][55][56][57]. Mutual antifungal activity against at least one of the toxigenic P. echinulatum and P. commune strains was already confirmed in 85 strains of 17 Penicillium species, including P. chrysogenum P. crustosum, and P. griseofulvum [57].…”

Effect of Cladosporium cladosporioides on the Composition of Mycoflora and the Quality Parameters of Table Eggs during Storage

et al. 2021

The eggshells of 120 experimental one-day-old table eggs were contaminated with the spore suspension of Cladosporium cladosporioides, divided into three groups (A–C) and stored at three different temperatures (3 °C, 11 °C and 20 °C) for 28 days. Visible growth of molds on/in experimental eggs was not observed within the entire storage period. No significant differences in the numbers of molds were found between particular groups of eggs. However, the composition of egg mycoflora was greatly influenced by storage conditions. Three mold genera were identified using the PCR method. The highest mold numbers were determined on Day 14 (Groups A and C) and Day 21 (Group B) when the maximum relative humidity and dew point temperature were recorded. On the same days, the dominance of Penicillium spp. and the minimum eggshell firmness were observed. Noticeable changes in egg quality were observed in eggs stored at 20 °C, and most of these eggs were downgraded at the end of storage period. The growth ability differed significantly among three mold genera. Penicillium spp. and Fusarium spp. showed better growth intensity at increased values (0.91–0.94) of water activity (aw) indicating a possible risk associated with the occurrence of mycotoxins in the egg contents.

Background: This work has the objective to biocontrol the bayoud disease of date palm caused by the fungus Fusarium oxysporum f. sp. albedinis (Foa), is the major disease in Algerian palm groves of south western region. This in vivo biocontrol was done on date palm variety Deglet-Nour, using two antagonistic fungi species, Trichoderma harzianum and Aspergillus flavus.Methods: Twenty Foa isolates obtained from isolation of the spines carrying the typical symptoms of Bayoud disease were used. Two strains T. harzianum and A. flavus, were isolated from rhizosphere soils of the date palm trees. Using the greenhouse screening test, which was carried out on 3-4 month-old date palm seedlings at the rate of 5 ml of inoculum suspension.Result: A statistical analysis showed a significant (P less than 0.05), difference of Deglet-Nour seedlings reactions against Foa isolates and antagonistic fungi were observed. All date palm trees present susceptibility against Foa until the total mortality of seedlings. The biocontrol test showed that two antagonists showed different reaction, with the complete resistance for seedlings treated by T. harzianum with the mortality rate (rm%) reduced at 100%, while, the second antagonist A. flavus reduced the rm% at 25%. We can apply of these antagonistic fungi to protect our groves contaminated by Bayoud disease and also contain this susceptible commercial variety.

“…A higher frequency of Aspergillus and Penicillium colonies was detected in the rhizosphere of tomato plants treated with B. subtilis SV41 as compared to the initial state (before planting) and to control soil. Aspergillus and Penicillium have been reported to be antagonistic to various Fusarium species (Dong and Cohen, 2002;Brzezinska and Jankiewicz, 2012;Mejdoub-Trabelsi et al, 2017). In fact, Sreevidya and Gopalakrishnan (2016) demonstrated that P. citrinum VFI-51 is able to produce siderophores, indole 3-acetic acid, hydrocyanic acid, lipase, protease, β-1,3 glucanase, and volatile compounds and also capable to compete with other pathogenic microorganisms such as Fusarium species (Aydi Ben Abdallah et al, 2015;Mejdoub-Trabelsi et al, 2017).…”

Two endophytic bacteria, Bacillus subtilis SV41 (KR818071) and B. amyloliquefaciens subsp. plantarum SV65 (KR818073), were assessed under field conditions for their capacity to control tomato Fusarium wilt in tomato and their effects on soil microbial activity. Six months after planting, Fusarium wilt severity, estimated through the vascular browning extent in tomato stems, was significantly reduced by 82.3 and 88.2% compared to control following bacterial treatments. The frequency of F.oxysporum reisolation from roots, collars and stems was also significantly lowered in treated plants compared to controls. These effects were associated with a significant improvement, by 10.6 to 16.3%over control, in plant height and root fresh weight and an increase in fruit production by 8.4-12.5%. As for microbial activity, F. oxysporum population in the rhizosphere of tomato plants treated with B. subtilis SV41 and B. amyloliquefaciens subsp. plantarum SV65 was reduced by 87.5-91.7%compared to the initial soil (sampled before planting) and by 88.4-92.3% relative to the rhizospheric soil of untreated plants (control soil). A significant enhancement in the total culturable bacterial community was also noted in the rhizosphere of tomato plants treated with both strains compared to initial and control soils where a significant enrichment in Pseudomonas and actinobacteria community was recorded.
