Phytohormonal activity (auxins, gibberellins, cytokinins) was tested in the supernatant of a culture of Arthrobacter sp. Crude extract of the phytohormonal fraction was used as substrate for the growth of Lactuca sativa seedlings. Treating with bacterial hormones resulted in an increased plant develop- ment. Furthermore, a sharp increase of the acid phosphatase activity was observed in the roots.
