Effects of plant extracts on cultures grown in M9 minimal media. Growth of P. syringae pv. phaseolicola NPS3121 in M9 minimal medium supplemented with bean leaf extract, apoplastic fluid and bean pod extract. At mid log phase (OD_{600 nm} 0.6) the cultures were supplemented with 2% of plant extracts. Culture density was measured by spectrophotometry after induction during 6 hours. The bean extracts increased bacterial growth rate on supplemented media in comparison to non supplemented media.
