“…However, DOR contains significant amounts of phytotoxic ingredients. For that reason, fungal pretreatments of DOR to get rid of the toxic compounds have been intensively studied during the last years [37]. It was demonstrated that fungus-treated DOR enhances the growth of tomato plants and hence is applicable as a valuable organic fertilizer [38–40].…”

The basidiomycete Chondrostereum purpureum (Silverleaf fungus) is a saprotroph and plant pathogen commercially used for combatting forest “weed” trees in vegetation management. However, little is known about its lignocellulose-degrading capabilities and the enzymatic machinery that is responsible for the degradative potential, and it is not yet clear to which group of wood-rot fungi it actually belongs. Here, we sequenced and analyzed the draft genome of C . purpureum (41.2 Mbp) and performed a quantitative proteomic approach during growth in submerged and solid-state cultures based on soybean meal suspension or containing beech wood supplemented with phenol-rich olive mill residues, respectively. The fungus harbors characteristic lignocellulolytic hydrolases (GH6 and GH7) and oxidoreductases (e.g. laccase, heme peroxidases). High abundance of some of these genes (e.g. 45 laccases, nine GH7) can be explained by gene expansion, e.g. identified for the laccase orthogroup ORTHOMCL11 that exhibits a total of 18 lineage-specific duplications. Other expanded genes families encode for proteins more related to a pathogenic lifestyle (e.g. protease and cytochrome P450s). The fungus responds to the presence of complex growth substrates (lignocellulose, phenolic residues) by the secretion of most of these lignocellulolytic and lignin-modifying enzymes (e.g. alcohol and aryl alcohol oxidases, laccases, GH6, GH7). Based on the genetic and enzymatic constitution, we consider the ‘marasmioid’ fungus C . purpureum as a ‘phytopathogenic’ white-rot fungus (WRF) that possesses a complex extracellular enzyme machinery to accomplish efficient lignocellulose degradation during both saprotrophic and phytopathogenic life phases.

The article seeks to thoroughly review the published literature and diverse awareness regarding natural waste including agricultural residues and food debris. Attention is drawn to current-day techniques of natural waste recovery. The concept of natural waste and the developed new ways of recovery are reviewed to promote knowledge transfer of modern green technologies for sustainable society and new processes that may be incorporated as a starting step or intermediate step during recovery of agro-industrial residues for better production of added-value products. The approach is directed toward maximizing the value of biomass feedstock, as well as to reduce the environmental impact of the waste. The article focuses on processing routes of natural waste with eco-friendliness by applying various preservation technologies, the conventional and the novel at forefront the improved valorization of by-products that lead to advanced industries including biorefineries. Applications of the produced added-value products are also involved.
