Table 6 Protein kinase (PK) inhiation (i.e. zone’s diameter in mm ± SD) during Streptomyces hyphae formation of isolated bacterial extracts (bald zone indicates PK inhibition while clear zone shows cytotoxicity)

From: An assessment on the role of endophytic microbes in the therapeutic potential of Fagonia indica

Bacterial extracts Protein kinase inhibition zones mm ± SD
Bald zone Clear zone
E. hormaechei 17 ± 0.92b
S. maltophilia 12 ± 1.04a
B. tequilensis 42 ± 1.21a
Erwinia sp. 14 ± 1.10a
P. dispersa 18 ± 0.81b
P. cypripedii 12.99 ± 1.01a
E. cloacae 12 ± 1.40a
B. subtilis 47 ± 0.72a
Surfactin 21 ± 1.02  
Amphotericin B 17.84 ± 1.8
  1. Surfactin and amphotericin B are positive controls
  2. Values are mean ± SD of triplicate analysis
  3. Letter a represent significant difference while b represents non-significant difference from their respective controls at P < 0.05, by one-way ANOVA in the column
