Enzymes and bioproducts produced by the ascomycete fungus Paecilomyces variotii

Due its innate ability to produce extracellular enzymes which can provide eco-friendly solutions for a variety of biotechnological applications, Paecilomyces variotii is a potential source of industrial bioproducts. In this review, we report biotechnological records on the biochemistry of different enzymes produced by the fermentation of the P. variotii fungus, including tannases, phytases, cellulases, xylanases, chitinases, amylases and pectinases. Additionally, the main physicochemical properties which can affect the enzymatic reactions of the enzymes involved in the conversion of a huge number of substrates to highvalue bioproducts are described. Despite all the background information compiled in this review, more research is required to consolidate the catalytic efficiency of P. variotii, which must be optimized so that it is more accurate and reproducible on a large scale.
