Effect of phosphate-solubilizing fungi Aspergillus awamori S29 on mungbean (Vigna radiata cv. RMG 492) growth.
A phosphate solubilizing fungus, Aspergillus awamori S29 was isolated from rhizoshpere of mungbean. The phosphate solubilizing activity of A. awamori S29 in liquid was 1,110 mg/L for tricalcium phosphate (TCP). The organism was able to solubilize various inorganic forms of phosphate at a wide range of temperatures. Among various insoluble phosphate sources tested, di-calcium phosphate was solubilized the most, followed by TCP. A. awamori S29 had significant effect (p < 0.05) on mungbean growth, total P and plant biomass under pot conditions, although no obvious difference in available P in soil and number of leaves was found compared to the control.
