Identification endophytic fungi of Nutgrass (Cyperus rotundus L.) as solubilizing phosphate and indole-3-acetic acid producers

Low phosphate content in the soil can cause insufficient plant needs. Besides, endophytic fungi of nutgrass have potential as a solvent and produce IAA (Indole-3-Acetic Acid). This study aimed to determine levels solubilizing production Acid) by identify isolates based on rDNA-ITS sequences. The methods used were isolation fungi, analysis production, molecular with Results purification, found five coded URT1, URT2, URT3, URT4, URT5. able around 54.03 - 87.83 ppm, highest produced URT4 isolate. 5.58 45.50 URT1 Based sequences, it showed that had 97.42% similarity Aspergillus tereus species, while UTR1 100% Fusarium oxyporum species. To conclude, from A. F. species high so they are candidates for biofertilizer.
