| Abstract: | Summary The action of methanol on the stimulatory or inhibitory effect produced by certain trace elements on citric acid production by Aspergillus niger was investigated. Methanol addition masked the stimulatory action of zinc addition and also eliminated the inhibitory effect of iron and manganese. It was also remarkable that some of the trace elements masked the toxic action of methanol on both acid production and growth. |
