Influences of carbohydrate, nitrogen, and phosphorus sources on the citric acid production by fungal endophyte P3I6.

Fungi are ecologically ubiquitous organisms on earth and regarded as one of the prolific sources of natural products. Fungal endophytes may provide essential prerequisite molecules to plant biochemical pathways which allow the efficient synthesis of primary and secondary metabolites. This study characterized the influences of various combinations of process parameters namely, carbohydrate, nitrogen, and phosphorus sources on citric acid (CA) production by the isolated fungal endophyte P3I6 from .
