Actinobacteria hydrolase producer in solid-state fermentation using licuri

ABSTRACT In recent times, green technologies have gained space and interest in many industrial sectors. Examples of this are enzymes, which can be obtained by solid-state fermentation using microorganisms agro-industrial residues as substrates. context, study aimed to verify the production hydrolases leading Arthrobacter polychromogenes Streptomyces violaceoruber strains producers influence moisture licuri [Syagrus coronata (Martius) Beccari] wheat The was performed at 28 °C/12 days, with different ratios bran/degreased almond cake: 0/70%, 10/60%, 35/35%, 60/10% 70/0%; peel, set 30%. medium ranged from 29 67%. Licuri peel added facilitate aeration medium; bran is commonly used produce lipases pectinases; degreased cake substrate work, since it inspired extractive semiarid region Brazil. ratio did not affect enzyme A. polychromogenes; however, S. violaceoruber, value significant for lipase but pectinases. prepared 67% equal (35/35%) presented highest enzymatic activities both 840.46 U/gds 15.53 pectinases, during Composite Central Design assays. With validation experiments, verified that substrates actinobacteria evaluated suitable microorganisms.
