Comparison of Two Methods for Counting Molds in Fermentations Using the Production of Bikaverin by Fusarium oxysporum CCT7620 as a Model.

The dry cell weight (DCW) measurement is one of the preferred methods to determine the growth of filamentous fungi. However, this technique is not applicable to insoluble culture media, besides being possibly influenced by the presence of extracellular biomass. The standard plate counting (SPC) is a reference method for detecting viable cells; however, it is referred as imprecise.
