Abstract

Aims:

The aim of this research was to evaluate the SSC of Aspergillus niger and Trichoderma reesei alone and in consortium for the citric acid production from sugarcane bagasse.

Methods:

Solid-State Cultivation (SSC) is characterized by microbial growth on solid supports often agroindustrial by-products in the near absence of free water conditions. Citric acid, an important by-product used in various sectors of the economy, can be obtained from the SSC using sugarcane bagasse, minimizing the cost of its production with the use of this industrial by-product.

Results:

The fungal consortiums have advantages over the isolated cultures, highlighting the best use of substrates due to enzyme supplementation, especially hydrolases.

Conclusion:

The results indicated a specific production of citric acid of 2.51 mg per g of biomass per hour, which was higher than that obtained when using the two fungi alone.
