“…Almost all citric acid is produced by fermentation, mainly via submerged fermentation of starch-or sucrose-based media by the filamentous fungus Aspergillus niger. Over the past 15 years, the research groups of Vandenberghe (2003 and Prado (2005aPrado ( , 2005b have focused on the solid-state fermentation of cassava bagasse for citric acid production. The fungal strain, Aspergillus niger LPB 21 was shown to be well adapted to cassava bagasse as a substrate.…”

Cassava, an important food crop, has been extensively employed as raw materials for various agri-industries to produce starch, bioethanol and other biobased products/chemicals. These cassava-based industries also generate large quantities of wastes/residues, rich in organic matter and suspended solids, and pose significant environmental issues. Their complex biochemical composition with high organic content endows them with a great potential for bioconversion into value-added products via biorefinery thereby providing economic and environmental sustainability to cassava industries. This state-of-the-art review covers the source, composition and characteristics of cassava industrial wastes and residues, and their bioconversion into value-added products, mainly biofuels (ethanol and butanol), biogas, biosurfactant, organic acids and other valuable biochemicals among others. This paper also outlines future perspectives with respect to developing more effective and efficient bioconversion processes for converting the cassava wastes and residues into high-value products.

“…The advantage of limited biomass production in glass columns was reported. In particular, for semi-pilot scale citric acid production, the same yield was achieved with a tray-type bioreactor as with a horizontal drum, but the tray-type had advantages in terms of costs and energy saving (Prado et al, 2005a(Prado et al, , 2005b).…”

“…The exchange of O 2 and CO 2 between the solid and the gas phase depends on those factors that increase the contact surface between the phases like: additional aeration generated by forced step of sterile air, agitation and moisture level of the substrate (Gervais and Molin, 2003). In a column bioreactor, the substrate humidity changes during fermentation owing to the saturated air passing through the medium, consequently, it was very important to define optimal conditions for these parameters in order to attain high growth and sporulation (Vandenberghe et al, 2004;Prado et al, 2005). Bacterial performance often occurs at high moisture levels.…”

Citric acid is an important organic acid, multifunctional with a wide array of uses. The objectives of this study were the isolation and selection strains of the genus Aspergillus, investigating the solubilization of phosphate of these isolates, verifying the expression rate of genes involved in the identification of isolates, and efficiency of citrate synthase in the citric acid production. To verify the mechanisms of the microorganisms in solubilizing phosphate into the medium in the citric acid production, Araxá rock phosphate was utilized. Further, citric acid was evaluated in two culture media, namely BD and SA. The amplification by the polymerase chain reaction was done by using primer ITS region and citrate synthase (P1/P2). The isolates of Aspergillus niger were efficient to solubilize phosphate. The isolate A. niger 00118 stood out in the solubilization with an increase as high as five times the amount of soluble phosphorus when compared with the control treatment. The results of citric acid production highlighted better influence conditions of the culture medium Sabouraud (SA) on its production. The P1/P2 primer was sensitive in distinguishing the isolates A. niger 00116, A. niger 00104, A. niger 00098 and A. niger 00118 in the analysis of citrate synthase enzyme genes.
