Antimicrobial activities of endophytic bacteria isolated from Ageratum conyzoides Linn.

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