From: 3-Methylxanthine production through biodegradation of theobromine by Aspergillus sydowii PT-2
Comparison of A. sydowii PT-2 (a) and A. tamarii PT-7 (b) on 3-menthylxanthine accumulation in the liquid culture. All data were present by mean value ± SD of three biological replications. The significance level was assessed by using the independent t-test of SPSS 20.0 compared with that in 100 mg/L of theobromine . * p < 0.05; ** p < 0.01; *** p < 0.001
