Some Factors Influencing the Efficiency of Production of Acetylmethylcarbinol by Rhizopus nigricans1

AUTOR(ES)
RESUMO

Incubation time had no effect on the efficiency ratio [dry weight-acetylmethylcarbinol (AMC)] during the incubation times tested. The mycelium was more efficient in synthetic media at pH 3 and 4 than at pH 5 and 6. Mycelium also produced AMC more efficiently in apple juice and in synthetic media containing yeast extract or vitamins, especially thiamine. KCl, MgSO4, and KH2PO4 had significant suppressing effects on AMC production in a synthetic medium.
