Considering some physiological aspects of the more prevalent
fungi isolated at fermentation, remark that
G. candidum, a yeast-like fungus, grows well under microaerophilic
conditions and high aw and M. ruber and P. paneum are also adapted
to environments of low oxygen pressure and show good growth
under these fermentation conditions. P. paneum is a species closely
related to Penicillium roqueforti, which has an optimum pH for
growth between 4.0 and 5.0, and tolerates high levels of CO2
, as well as organic acids commonly
found in the fermentation of cocoa . Both species
were also present in the mycobiota of other foods fermented by
lactic or acetic acid bacteria
