Résumé :
Bacillus spp. are well known to protect plants from seed or soil-borne pathogens by the synthesis of various metabolites with antimicrobial activity, such as hy?drolytic enzymes and antibiotics. This study aimed to select the most effective Bacillus spp. from a group of ten antagonistic strains by antifungal activity assay. Bacillus strains were primarily isolated from the soil and identified as B. safensis, B. pumilus and B. subtilis by 16S rDNA sequencing. The four analyzed fungi: Macrophomina phaseolina, Alternaria alternata, Cladosporium cladosporoides, and Sclerotinia sclerotiorum, were obtained from sunflower seeds and identified using PCR analysis and primers specific for ITS region. The antifungal activity of bacterial strains was examined in a dual plate assay. Bacillus spp. demonstrated the highest antagonism against S. sclerotiorum, followed by C. cladosporoides, M. phaseolina, and A. alternata, with an average percentage of growth inhibition (PGI) of 77%, 70%, 64% and 59%, respectively. Overall, Bacillus spp. included in this study demonstrated a rather strong biocontrol potential, although the effect of particular strain varied depending on the tested fungi. The highest antagonistic effect toward M. phaseolina and A. alternata was exhibited by B. safensis B2 and B. pumilus B3. B. pumilus B11 and B. subtilis B32 were the most efficient against C. cladosporoides, whereas B. pumilus B3 and B. subtilis B7 had the highest antifungal activity against S. sclerotiorum. Findings point to the fact that the most effective Bacillus spp. could be used as potential biocontrol agents for improving plant health and productivity.

Texte intégral
Résumé :
A new semi-selective medium, acidified weak potato-dextrose agar (AWPDA) with Mertect (active ingredient: thiabendazole), was developed for the isolation and enumeration of Alternaria species from samples of soil and plant debris. The medium was selected based on growth inhibition tests against Alternaria and several other commonly encountered saprobic fungi utilizing three antifungal agents, Botran (active ingredient: dichloran), Bayleton (active ingredient: triadimefon), and Mertect, and two basal media, acidified potato-dextrose agar (APDA) and AWPDA. Botran inhibited growth of Rhizopus stolonifer moderately, but had little effect on Cladosporium cladosporoides, Fusarium oxysporum, Penicillium chrysogenum, or Trichoderma harzianum. Bayleton inhibited growth of R. stolonifer and C. cladosporoides severely, and inhibited growth of F. oxysporum, P. chrysogenum, and T. harzianum moderately. Mertect inhibited growth of C. cladosporoides, F. oxysporum, P. chrysogenum, and T. harzianum completely, but had little or moderate effect on R. stolonifer. All three antifungal agents inhibited growth of Alternaria species slightly or moderately. The combination of Bayleton and Mertect inhibited growth of all fungi severely. A comparison of recovery rates of Alternaria from soil and plant debris samples on AWPDA with Mertect and weak potato-dextrose agar (WPDA) revealed that Alternaria spp. accounted for 63.6%–81.0% of recovered fungal isolates on AWPDA with Mertect as compared to 0.6%–2.7% of recovered isolates on WPDA. The AWPDA medium with Mertect exhibited superior selective growth of Alternaria species from samples of soil and plant debris, and will be useful in studies where the recovery and enumeration of Alternaria species is necessary.Key words: Alternaria, AWPDA, selective media, sporulation, Mertect.

Résumé :
Objective: This study evaluated the Chaetomium cupreum extracts as biocontrol agents against four plant pathogenic fungi (Cladosporium cladosporioides, Fusarium oxysporum, Phomopsis azadirachtae, and Rhizoctonia solani).Method: The antifungal activity of n-butanol and ethyl acetate extracts of C. cupreum was evaluated against plant pathogenic fungi using food poison method.Result: In n-butanol extract, the percentage inhibition of mycelial growth against C. cladosporoides was 88.3±0.1, F. oxysporum was 59.4±0.2, R. solani was 56.2±0.9, and P. azadirachtae was 52.0±0.1at 0.25 mg/ml, respectively. In ethyl acetate extract, the percentage inhibition of mycelial growth against C. cladosporoides was 86.0±0.5, F. oxysporum was 66.4±0.1, P. azadirachtae was 55.2±0.9, and R. solani was 52.0±0.1 at 0.25 mg/ml, respectively.Conclusion: It was found that n-butanol extract is more effective than ethyl acetate extract of C. cupreum. Future studies will focus on the purification and characterization of compounds of C. cupreum and their biocontrol capacity with the mechanism for plant pathological applications.

This study was conducted to discover wide spectrum of endophyte diversity from the Zingiber officinale Rosc. Endophytic fungi were obtained from different plant tissues. All the isolated strains were identified up to genus level following described colony morphology. The recognized five different morphotypes were subjected to sequence analysis of internal transcribed spacer (ITS) gene. Fusarium proliferatum, Fusarium solani and Cladosporium cladosporoides were identified based on comparison of the BLAST results and phylogenetic identification.

Résumé :
The chemical composition and antifungal activity of the essential oil of an endemic Serbian plant Nepeta rtanjensis Diklic & Milojevic was studied. The essential oil was isolated from cultivated plants. Inhibition of mycelia growth of five micromycetes, two Alternaria species originally isolated from N. rtanjensis, Cladosporium cladosporoides, Trichoderma viride and Bipolaris spicifera, were tested using the agar dilution method. The essential oil of N. rtanjensis, the main component of which was 4aa,7a,7ab-nepetalactone, showed strong antifungal activity against all the tested micromycetes. The minimum inhibitory concentration of N. rtanjensis essential oil ranged from 0.6 to 1.4 ?g mL-1. The fungi most sensitive to the tested oil were Alternaria species, while Trichoderma viride was the most resistant.

Plants Suruhan (Paperomia pellucida L. Kunth) has traditionally been used as a drug abscesses, boils acne, skin diseases, headaches, relieve pain in arthritic.Various properties owned by the plant Suruhan make this plant as a major commodity medicinal plants are cultivated by the people. Suruhan pharmacological function can not be separated because their secondary metabolites that allegedly resulted from their symbiosis with endophytic microbes such as fungi. Endophytic fungi are microscopic fungi that live intracellularly in the plant tissue without damaging the host. This study aimed to isolate and identify endophytic fungi on plant fruit organs errand. Isolation of endophytic fungi on errands obtained 15 isolates comprising of Fusarium sambucinum, Cladosporium cladosporoides, Cladophialophora sp.
