The P concentration (A) and oxalic acid (B) concentration in each treatment after six days of incubation. The error bars represent the standard deviations of four replicates. The significant differences among the treatments were identified by Tukey’s honestly significant difference test (p < 0.05) via one-way ANOVA. Rho: Rhodotorula mucilaginosa; POX: P. oxlaicum
