Characterization of amylase, lipase and xylanase produced by actinobacteria cultivated in licuri [Syagrus coronata - (Martius) Beccari] residues

In order to seach for different microbial sources of enzymes, Arthrobacter polychromogenes CDPI-30 and Streptomyces violaceoruber CDPA-32 were individually cultivated in licuri [Syagrus coronata - (Martius) Beccari] residues. It was possible detect some enzymes but amylase, lipase xylanase selected a basic characterization. The optimum conditions observed at pH 6 7 40 – 70 °C amylases, 4 50 90 lipases 8 10 20 xylanases. best stabilities, evaluated under were, way, result from the optimal conditions. Additionally, substrate saturation not soluble starch xylan until 15 mg/mL p-nitrophenyl palmitate 9.95 µmol/mL. These results indicate that both, actinobacteria agroindustrial residues, are good choices produce industrial enzymes.
