Potential of Filamentous Fungi for Production of Exo Hydrolases with Biotechnological Interest: Influence of Fermentative Process on Morphology, Cytoskeleton and Secretion of ²-D-fructofuranosidases, Phytases and Tannases

Abstract

The world global market of industrial enzymes moves billions of dollars per year, with an estimative of US$ 6.2 billions of dollars for 2020. Under this context, the demand by enzymes with new properties is growing each year. On the other hand, the obtainment of enzymes has used the same sources, without novelties. The microorganisms are the most important and attractive sources of enzymes, especially the filamentous fungi. Considering this aspect there is a reduced numbers of fungal strains able to produce these biomolecules considering the microbial diversity, which still stay poorly explored. The production of enzymes by filamentous fungi has been performed using different fermentative process as Solid-State Fermentation (SSF) and Submerged Fermentation (SbmF). In the last years, a new alternative technology was proposed for production of enzymes, the Biofilm Fermentation (BF), which associates advantages from SSF and SbmF. Them, main objective of this project is to study the production of exo-hydrolases with biotechnological potential (²-D-fructofuranosidases, phytases and tannases) by filamentous fungi under SbmF and BF, considering especially the morphology patterns. It is known that the fungal morphology under both fermentation processes is different, what is very relevant considering that the fungal morphology has direct influence on the enzyme secretion. However, a depth study considering this aspect focused on the cytoskeleton proteins (actin and microtubules) was not conducted until this moment. To control the fungal morphology is an important way to improve the production of enzymes with biotechnological application. Additionally, the enzymes obtained will be purified and biochemically characterized. Then, this project can be characterized as basic and applied research for different knowledge areas (biological diversity, biochemistry, microbiology and biotechnology). (AU)
