Effects on plant growth (EPGs) of bacterial communities collected from ponds or rivers. A–O indicate bacterial communities recovered from water samples. EPGs were evaluated based on the number of fronds after 7 days of cultivation compared to that of an aseptic control. There were 91.33 (±4.50), 85.67 (±2.05), and 81.33 (±6.60) fronds at the end of control experiments for bacterial communities A–E, F–J, and K–O. Error bars show the standard errors and include errors among treatments performed in triplicate and the control
