제목 Effective antagonist screening, Antifungal substance characterization, and novel oxygenation for foam-stat cultivation of Bacillus sp. GB16 for plant disease (damping-off) control
초록 Soil-borne infectious disease including Pythium aphanidermatum and Rhizoctonia solani causes severe damage to plants, such as cucumber. This soil-borne infectious disease was not contolled effectively by chemical pesticide. Since these diseases spread through the soil, chemical agents are usally ineffective. Instead, biological control, including antagonistic microbe can be used as a preferred control method.
An efficient method was developed to select an antagonistic strain to be used as a biological control agent strain. In this new method, surface tension reduction potential of an isolate was included in the ‘decision factor’ in addition to the other factors, such as growth rate, and pathogen inhibition rate.
Considering these 3 decision factors by a statistical method, an isolate from soil was selected and was identified as Bacillus sp. GB16. In the pot test, this strain showed the best performance among the isolated strains.
