Agro-Industrial Residues: Eco-Friendly and Inexpensive Substrates for Microbial Pigments Production

Many commodities are abundantly produced around the world, including soybean, corn, rice sugarcane, cassava, coffee, fruits, and many others. These productions responsible for generation of enormous amounts daily residues, such as cassava sugarcane bagasses, husk, coffee peel. residues rich sources renewable energy can be used substrates industrial interest products. Microorganisms useful biofactories, capable producing important primary secondary metabolites, alcohol, enzymes, antibiotics, pigments, other molecules. The production pigments was reported in bacteria, filamentous fungi, yeasts, algae. natural microbial very promising because synthetic colorants present a long history allergies toxicity. In addition, biological activities, antioxidant antimicrobial that interesting applications. use inexpensive these metabolites is attractive, considering agro-industrial generated high usually problem to industry. Therefore, this article we review using during current decade (2010–2020), both submerged solid state fermentations, wild-type genetically modified microorganisms, laboratorial large-scale bioprocesses, possible activities related pigments.
