Rhizopus nigricans and Penicillium expansum produced 2,3-butylene glycol which accumulated in natural and artificial media with time. Mycelial mats of P. expansum decreased the quantity of a diacetyl substrate and converted part of this substrate into acetylmethylcarbinol (AMC) and 2,3-butylene glycol. Mycelial mats of P. expansum also decreased AMC substrate with the formation of 2,3-butylene glycol. 2,3-Butylene glycol decreased slightly during incubation with the fungal mat. The formation of AMC was suppressed significantly by cysteine and ascorbic acid.
黑根霉和扩展青霉产生2,3 - 丁二醇，其在天然和人工培养基中会随时间积累。扩展青霉的菌丝垫减少了双乙酰底物的量，并将部分该底物转化为乙酰甲基甲醇（AMC）和2,3 - 丁二醇。扩展青霉的菌丝垫还通过形成2,3 - 丁二醇而减少了AMC底物。在与真菌垫一起培养期间，2,3 - 丁二醇略有减少。半胱氨酸和抗坏血酸显著抑制了AMC的形成。
