A semi‐submerged biodisk apparatus provided with inert matrix for cell entrapment, previously employed with success for alcohol fermentation, is proposed in this study to overwhelm the well‐known problems related to the continuous citric acid production. This immobilized‐mycelium system shows at the same time a remarkable increase in citric acid volumetric productivity, with respect to a Continuous Stirred Tank Reactor, but the same progressive activity loss evidenced in the past with comparable immobilized‐cell reactors.
