Abstract
|
|
|
|
In order to prevent the quality deterioration of rice from microbial infection, we investigated antimicrobial activities of Morun albalinne, Glycyorrhiza uralensis, Sargassum siliquastrum, and Ecklonia cava against isolated microorganisms from the paddy and warehouses. The major types of the bacteria grown in the paddy and rice warehouses were Sphingomonas paucimobilis, Arthrobacter atrocyaneus, and Bacillus spp. such as Bacillus cereus. Additionally Deuteromycetes, Aspergillus spp. and Penicillum spp. were considered as major contaminant microorganisms in the paddy and rice warehouses. As results of the paper disc assay against the isolated microorganisms, the ethanol extracts with Morun albalinne, Glycyorrhiza uralensis, Sargassum siliquastrum, and Ecklonia cava showed effective antimicrobial activities. Especially, Morun albalinne showed the strongest growth inhibition on the isolated bacteria at 0.0025~0.0075%.
