Supplementary Figure S1: Nucleotide sequence homology comparison of ITS1, 5.8S rRNA gene, and ITS2 sequences of fungal strain isolated from green coffee been using NCBI Blast; primers: ITS1 (5′TCCGTAGGTGAACCTGCGG3′) and ITS4 (5′TCCTCCGCTTATTGATATGC3′); polymerase chain reaction (PCR) conditions: initial denaturation temperature of 94 °C for 3 min, followed by 32 cycles of denaturation, annealing and extension (94 °C for 45 s, 56 °C for 1 min, and 72 °C for 1 min) and final extension at 72 °C for 10 min.

Supplementary Figure S2: Analysis of OTA production by different Aspergillus ochraceus strains by thin-layer chromatography (TLC); L1: OTA standard (200 ng); L2: A. ochraceus (isolated from coffee beans); L3: A. ochraceus (MTCC 1810); L4: A. ochraceus (MTCC 4893); L5: A. ochraceus (MTCC 4643); L6: A. ochraceus (MTCC 1877); L7: A. ochraceus (MTCC 6037); L8: A. ochraceus (MTCC 7476).
