HPLC profile of extracts from (A) LO2026 (background control strain), (B) AN8383.4Δ PKS deletant (C) AN9259.4Δ prenyltransferase deletant and (D) AN8142.4Δ as detected by UV at 254 nm and mass spectrometry. Austinol 1 [M+H]+ m/z = 459 and dehydroaustinol 2 [M+H]+ m/z = 457 are detected using positive ion mode and 3,5-dimethylorsellinic acid 3 [M-H]− m/z = 195 is detected using negative ion mode.
