Inhibition of M. oryzae by B. gladioli BBB-01 via fumigation. (A) M. oryzae and B. gladioli BBB-01 were cultivated separately on two agar plates within a sealed compartment as illustrated. M. oryzae was grown on PDA, while B. gladioli BBB-01 was grown on KBA, LBA, or PDA as indicated. The growth of M. oryzae alone was taken as the control. The radial colony of M. oryzae on days 0 and 10 after fumigation was shown. (B) P. aeruginosa and B. gladioli BBB-01 were cultivated on KBA, LBA, or PDA. A paper strip soaked with picric acid and sodium carbonate was stuck on the lid within the sealed petri dish. The appearance of brown color of the paper indicates the presence of hydrogen cyanide as indicated by the standard strip.
