Abstract

The phytohormone indole acetic acid (IAA) is synthesized both by plants
and microorganisms. This phytohormone performs its activity on plant growth and
development by regulating cell elongation, enlargement, and division. The production of
IAA is one of the essential criteria that discriminate the plant growth-promoting
microorganisms. The present work involves the isolation of bacteria from the rhizosphere
of different localities of the Egyptian flora and screening these isolates for the production
of Indole acetic acid. Thirty-three bacterial isolates were obtained from clay and sandy
soils. 67% of bacterial isolates were obtained from clay soil while 33% were obtained
from sandy soil. The isolated bacteria produced a high amount of IAA in the range of
6.36 and 62.59 μg /ml. Thus, these bacteria are recommended as sustainable biofertilizers
for their high production of IAA.
