Abstract

Abstract:

In order to isolate and screen endophytic fungi with inhibitory activity from Acorus calamus L., active strains were screened through modified TTC micro-dilution method. MIC (minimum inhibitory concentration) and MBC (minimum bactericidal concentration) were detected using 18 food spoilage strains. Results indicated that 40.7% endophytes exhibited antimicrobial activity and 12.39% endophytes exhibited higher antimicrobial activity. In addition, strain S9 exhibited the broadspectrum antimicrobial activity to bacteria, yeast and mycelia fungi. Active endophytic strains from A. calamus L. are potential resources for food preservation.

Key words: Acorus calamus L., endophytic fungi, antibacterial activity
