Under similar conditions, pigment and arylamine are not produced by an adenine-requiring strain of Schizosaccharomyces octosporus. Culture filtrates containing arylamine promote the growth of Sch. octosporus in adenine-free medium, but an adenine-requiring lactobacillus responds only after a considerable lag. The results are interpreted to mean that the arylamine is, or is derived from, a precursor of adenine, whose conversion to adenine is impaired by deficiency of biotin., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-7-1-2-54
