“…Tannase is also used in clarification to remove the unwanted bitterness in many fruits juices, lowering haze without deteriorating juice quality (Rout and Banerjee, 2006;Srivastava and Kar, 2010). In animal feed, tannase is used to reduce the anti-nutritional effects of tannins and improve animal digestibility (Graminha et al, 2008;Murugan and Al-Sohaibani, 2010).…”

-Aspergillus aculeatus tannase was immobilized on several carriers by entrapment and covalent binding with cross-linking. Tannase immobilized on gelatin with cross-linking agent showed the highest activity and immobilization yield. The optimum pH of the immobilized enzyme was shifted to a more acidic range compared with the free enzyme (from pH 5.5 to pH 5.0). The optimum temperature of the reaction was determined to be 50°C for the free enzyme and 60°C for the immobilized form. The thermal stability, as well as stability over a wide range of pH, was significantly improved by the immobilization process. The calculated K m of the immobilized tannase (11.8 mg ml -1 ) is higher than that of the free tannase (6.5 mg ml -1 ), while V max of the immobilized enzyme (0.32 U (µg protein) -1 ) is lower than that of the free tannase (2.7 U (µg protein) -1 ). The immobilized enzyme was able to retain 84 % of the initial catalytic activity after 5.0 cycles.

“…Some examples of these wastes include the bagasse and peels generated in the beverages and juice industries, coffee pulp obtained in the coffee industry and husks from the cereal industries, classified as agro industrial by-products (Graminha et al, 2008;Orzua et al, 2009). These residues are formed by lignocellulose which in turn is formed by of lignin, hemicellulose and cellulose.…”

Biological wastes contain several reusable substances of high value such as soluble sugars and fiber. Direct disposal of such wastes to soil or landfill causes serious environmental problems. Thus, the development of potential value-added processes for these wastes is highly attractive. These biological wastes can be used as support-substrates in Solid-State Fermentation (SSF) to produce industrially relevant metabolites with great economical advantage. In addition, it is an environment friendly method of waste management. In this study were analyzed six different Mexican agro industrial residues to evaluate their suitability as support-substrate in SSF, between physicochemical properties that have included Water Absorption Index (WAI), Critical Moisture Point (CHP) and Packing Density (PD). The selection of an appropriate solid substrate plays an important role in the development of an efficient SSF process. The results provided important knowledge about the characteristics of these materials revealing their potential for use in fermentation processes.

“…This enrichment is possible through the growth of microorganisms "generally recognized as safe" or "GRAS" such as A. niger, A. oryzae, and A. awamori. These fungi are well-known producers of lipases, proteases, and amylases and can also enrich the cake so that it can be fully used in animal feed to substitute high cost components [75][76][77].…”

Abstract:The establishment of a bioeconomy era requires not only a change of production pattern, but also a deep modernization of the production processes through the implementation of novel methodologies in current industrial units, where waste materials and byproducts can be utilized as starting materials in the production of commodities such as biofuels and other high added value chemicals. The utilization of renewable raw resources and residues from the agro-industries, and their exploitation through various uses and applications through technologies, particularly solid-state fermentation (SSF), are the main focus of this review. The advocacy for biocatalysis in green chemistry and the environmental benefits of bioproduction are very clear, although this kind of industrial process is still an exception and not the rule. Potential and industrial products, such as biocatalysts, animal feed, fermentation medium, biofuels (biodiesel, lignocelulose ethanol, CH 4 , and H 2 ), pharmaceuticals and chemicals are dealt with in this paper. The focus is the utilization of renewable resources and the important role of enzymatic process to support a sustainable green chemical industry.
