Article Abstract
This paper by Jeffrey K. Glenn and Michael H. Gold (Department of Chemical, Biological, and Environmental Sciences, Oregon Graduate Center) reported for the first time the purification and characterization of a manganese peroxidase. It was shown that the extracellular heme b-containing oxidoreductase purified from the basidiomycete Phanerochaete chrysosporium requires hydrogen peroxide and Mn(II) for the oxidation of a variety of different compounds. This discovery in 1985 was the prelude to countless research papers on structure-function relationships of manganese peroxidases, their ecological role(s) in the degradation of lignocellulose and lignin and on their relevance for industrial and commercial applications. This paper has been cited 575 times in Scopus. A Scopus search for the term manganese peroxidase yielded 6163 results (April 2022).

Soil compaction is a pressing issue in agriculture that significantly hinders plant growth and soil health, necessitating effective strategies for mitigation. This study examined the effects of sugarcane bagasse, both in its raw form and as biochar, along with biological activators (Bacillus simplex UTT1 and Phanerochaete chrysosporium) on soil characteristics and corn (Zea mays L.) plant biomass in a compacted soil.

Background: The composition of anaerobically digested sludge is inherently complex, enriched with structurally complex organic compounds and nitrogenous constituents, which are refractory to biodegradation. These characteristics limit the subsequent rational utilization of resources from anaerobically digested sludge. White-rot fungi (WRF) have garnered significant research interest due to their exceptional capacity to degrade complex and recalcitrant organic pollutants.

Aims: The sand-fixing desert shrub Artemisia sphaerocephala produces a large amount of seed mucilage, which plays crucial roles in the adaptation of this species to desert environments. Seed mucilage has been shown to be degraded by Phanerochaete chrysosporium from habitat soils, but the process and products of this degradation remain unclear. To fill this gap, we explored the factors and processes involved in mucilage degradation.

Article Synopsis
- White-rot fungi, like Phanerochaete chrysosporium, are essential for breaking down lignocellulosic biomass, which includes important components like cellulose, hemicellulose, and lignin, thus contributing to the carbon cycle.
- These fungi use various enzymes—such as lignin peroxidases and cytochrome P450 monooxygenases—to degrade lignin and its derivatives, though more research is needed to fully understand the metabolic pathways involved.
- The metabolic flexibility of these fungi allows them to adapt their enzyme production, specifically through the interplay of key pathways, enhancing their efficiency in degrading lignin for potential biotechnological applications.
