PsM6 and PjM15 utilized tryptophane as a precursor
for their growth and IAA production. The maximum
production of IAA was observed in PjM15 compared
with PsM6. Similarly, PsM6 and PjM15 utilized tricalcium
phosphate as the sole source of phosphate. The
strain PjM15 exhibited higher rate of phosphate solubilization
than PsM6.
