Co-cultivation of L. enzymogenes and P. aphanidermatum on agar plates. (A) Co-culture for 24 h (before inhibition zones formation); (B) Co-culture for 48 h (during inhibition zones formation); (C) Co-culture for 96 h (after inhibition zones formation). In each of these three sets, the left plate was L. enzymogenes and P. aphanidermatum co-cultured and the right plate was L. enzymogenes alone. (D) Lysobacter-Pythium assay with or without filter papers. The left plate shows that the filter paper alone does not block the oomycetes growth, and 1 indicates the hyphae grown area under the filter paper without OH11, while 2 indicates a clear inhibition zone under filter paper with OH11; the right plate represents Lysobacter-Pythium assay without filter papers.
