Abstract
The production of citric acid from carob pod by Aspergillus niger in solid-state fermentation was investigated. The maximal citric acid concentration (176 ± 4 g kg −1 dry pod), biomass dry weight (30 ± 0.7 g kg −1 wet substrate), citric acid yield (55 ± 2%), and sugar utilization (64 ± 2.5%) were obtained at a particle size of 0.5 mm, moisture level of 65%, pH of 6.5, and temperature of 30°C. The addition of 6% (w/w) methanol into the substrate increased the concentration of citric acid from 176 to 264 g kg −1 dry pod.
