Table 1.
Compounds per fraction identified in Aspergillus welwitschiae isolate CCMB 674 and their chemical properties. Columns represent retention time (RT), pseudo-molecular ion mass-to-charge ratio ([M + H]+), sodium adducts mass-to-charge ratio ([M+Na]+), liquid chromatography in positive mode mass-to-charge ratio (LC-MS m/z), and the identified molecule. * Identifies isomer compounds.
