“…All the isolates showed significant differences over the control. Shirasangi and Hegde (2018) also reported that endophytes have antagonistic potential against Rhizoctonia. In their report, they collected a total of 26 fungal endophytes from the root, of different parts of healthy tomato samples from 30 locations in three districts of northern Karnataka.…”

Dry root rot is a major threat to chickpea production globally. The disease is caused by Rhizoctonia bataticola. The recent rise in global temperature and worsening of drought spells has aggravated dry root rot outbreaks in chickpeas. To combat this necrotrophic pathogen, the present study was conducted to inhibit the pathogen by using potential plant growth-promoting microorganisms (PGPMs). Forty isolates of endophytic fungal PGPMs were isolated from healthy plant parts of chickpeas in a potato dextrose agar medium. Isolates were screened for antagonistic potential and bioactive compound production against R. bataticola. Using ITS genes BLAST analysis, the putative endophytic fungal PGPM was identified at the molecular level. Finally, the extraction of bio-active compounds and metabolic profiling was carried out by solvent extraction method and GC-MS/MS technique, respectively. Among forty isolates, FEPGPM-34 produced the maximum concentration of bio-active compounds with the highest percent mycelial inhibition of 74.61. Through molecular characterization and BLAST analysis, the isolateFEPGPM-34 was identified as Trichoderma asperellum. GC-MS/MS analysis of T. asperellum extract showed the presence of 65 compounds at different retention times and mass to charge (m/z) ratios with 13 compounds exhibiting antimicrobial properties. Hence, PGPMs can be exploited for managing dry root rot disease.

“…Antagonistic activity of the endophytic bacteria against the filamentous fungus was determined by the dual culture technique (Chen et al 2012;Naoufal et al 2018;Shirasangi and Hegde 2018). M. canis from stock culture was cultured on PDA plates at room temperature for 14 days.…”

Abstract. Boonman N, Chutrtong J, Wanna C, Boonsilp S, Chunchob S. 2023. Antimicrobial activities of endophytic bacteria isolated from Ageratum conyzoides Linn. Biodiversitas 24: 1971-1979. Endophytic bacteria were isolated from various parts of Ageratum conyzoides Linn. Total 35 isolates were obtained which were consisting of eight isolates from the roots (AconR1-AconR8), nine isolates from the stems (AconS1-AconS9), seven isolates from the leaves (AconL1-AconL7) and 11 isolates from the flowers (AconF1-AconF11). These endophytic bacteria were examined for their antimicrobial activities against human pathogenic bacteria and fungi. The AconR2 and AconR4 inhibited the growth of Shigella flexneri and Salmonella enterica ser. typhi, whereas Escherichia coli was only inhibited by AconR2. For the antifungal activities assay, all isolated endophytic bacteria revealed no effect on Candida albicans, while six endophytic isolates exhibited more than 80% mycelial growth inhibition against Microsporum canis. These highly effective isolates were identified by matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS). The Bruker scores revealed that AconR2 and AconR4 were identified as Pseudomonas aeruginosa, AconS1 and AconS6 were classified as Enterobacter asburiae, Acon L5 and Acon F9 were identified as Bacillus cereus. The results indicated that these endophytic bacteria isolated from A. conyzoides effectively inhibited the growth of human pathogenic filamentous fungi and showed promise for further development as novel antifungal agents.
