Kraft lignin biobleaching by a dye-decolorizing peroxidase from the Antarctic Pseudomonas sp. AU10 strain.

Pseudomonas sp. AU10 is an Antarctic psychrotolerant bacterium that produces a dye-decolorizing peroxidase (DyP-AU10). The recombinant enzyme (rDyP-AU10) is a heme-peroxidase that decolors dyes and modifies kraft lignin.

A bacterial cold-active dye-decolorizing peroxidase from an Antarctic Pseudomonas strain.

DyP (dye-decolorizing peroxidase) enzymes are hemeproteins that catalyze the HO-dependent oxidation of various molecules and also carry out lignin degradation, albeit with low activity. We identified a dyp gene in the genome of an Antarctic cold-tolerant microbe (Pseudomonas sp. AU10) that codes for a class B DyP.

Identification of Plant Compounds Involved in the Microbe-Plant Communication During the Coinoculation of Soybean with Bradyrhizobium elkanii and Delftia sp. strain JD2.

Delftia sp. strain JD2 is a betaproteobacterium characterized as a plant growth-promoting bacterium with a 'helper' function, enhancing the performance of rhizobial inoculant strains during the coinoculation of alfalfa and clover. In this work we analyzed i) the effect of the coinoculation with Bradyrhizobium elkanii and Delftia sp.
