2.1.5. Hormones production by the bacterial strains growing without
and with 15% of polyethylene glycol (PEG) in the growing medium
Bacterial strains were grown in LB medium with and without
15% PEG (1.50 MPa) for four days to determine the production of
these phytohormones. Treatments were replicated three times.
The PEG concentration here used (15%) was selected because
bacterial growth was quite considerable and it avoid problems in
the detection of these hormones.
