The two different endophytic species of Sphingomonas LK18 and
LK16 produce 35.19 and 25.46 μM in 50 mL broth respectively while,
Pseudomonas aeruginosa LK17 encodes for 31.13 μM in 50 mL culture
broth. By comparing the IAA amount produced by endophytic B.
subtilis LK14 and B. subtilis LK15, the former strain produce 52%
greater amount of IAA in LB broth medium.
