TL;DR: It is demonstrated that application of the laccase from S. cyaneus in the presence of ABTS to biobleaching of eucalyptus kraft pulps resulted in a significant decrease in the kappa number and an important increase in the brightness of pulps, showing the suitability of laccases produced by streptomycetes for industrial purposes.

TL;DR: The application of modern analytical techniques, such as nuclear magnetic resonance (NMR) and pyrolysis-gas chromatography-mass spectrometry (Py-GC-MS), have provided data on soil chemistry, and the combination of these two approaches offers promise in determining soil health status.

TL;DR: The oxidative potential of this enzyme to use phenolic compounds as natural redox mediators was shown through the coordinated action of SilA and acetosyringone (as mediator), which resulted in the complete detoxification of the azo-type dye Orange II.

TL;DR: HPLC analysis of the dyes after treatment revealed the complete disappearance of both dyes and mediator and a concomitant appearance of new chromatographic peaks which could be responsible of the residual toxicity detected in some cases.

TL;DR: An increase in both bacterial and fungal biomass as well as respiratory activity was detected in most burnt soils, and Shannon index values obtained from the DGGE profiles showed higher diversity for both Bacteria and Archaea domains in burnt soils compared with the control ones.
