“…Manganese peroxidase (MnP) belongs to the family of oxidoreductases and cannot react directly with the lignin structure [250]. There are two groups: (1) Manganese dependent peroxidase is an extracellular enzyme that requires both H 2 O 2 for lignin oxidation, Mn 2+ as a co-factor and (2) Manganese independent peroxidase is an extracellular enzyme that requires H 2 O 2 in lignin oxidation but does not need Mn 2+ (Figure 11) [258]. The major substrates of manganese peroxidase are low molecular weight substances and organic acid compounds.…”

Cultivation of Mushrooms and Their Lignocellulolytic Enzyme Production Through the Utilization of Agro-Industrial Waste

A large amount of agro-industrial waste is produced worldwide in various agricultural sectors and by different food industries. The disposal and burning of this waste have created major global environmental problems. Agro-industrial waste mainly consists of cellulose, hemicellulose and lignin, all of which are collectively defined as lignocellulosic materials. This waste can serve as a suitable substrate in the solid-state fermentation process involving mushrooms. Mushrooms degrade lignocellulosic substrates through lignocellulosic enzyme production and utilize the degraded products to produce their fruiting bodies. Therefore, mushroom cultivation can be considered a prominent biotechnological process for the reduction and valorization of agro-industrial waste. Such waste is generated as a result of the eco-friendly conversion of low-value by-products into new resources that can be used to produce value-added products. Here, we have produced a brief review of the current findings through an overview of recently published literature. This overview has focused on the use of agro-industrial waste as a growth substrate for mushroom cultivation and lignocellulolytic enzyme production.

BACKGROUND Chemically different types of dyes have been proven to be degraded by peroxidases of Phanerochaete chrysosporium. Hydrogen peroxide is required as a co‐substrate for peroxidases during the oxidation process. RESULTS Investigating the effect of glucose oxidase (GOx) (EC 1.1.3.4) on treatment of textile effluent containing recalcitrant diazo and azo dyes by P. chrysosporium was the main aim of this research. The effects of glucose, GOx and Mn2+ on chemical oxygen demand (COD), decolorization and manganese peroxidase (MnP) activity were evaluated in repeated batch operations. At the end of the fifth batch, the decolorization efficiency increased 4.18‐fold compared with reference batches (i.e. no additive received batches). An increase in MnP activity and COD removal percentage by 4.5‐ and 5‐fold, respectively, were observed when introducing GOx+glucose. CONCLUSION In vivo addition of GOx+glucose could increase the decolorization efficiency of real sample effluent not only by providing H2O2 for catalytic activity of peroxidases but also by providing gluconic acid, favoring the pH of the medium and increasing peroxidase activity as well. Also, these findings may be useful for discerning the role of manganese ions and oxidases of fungi as well as their interaction in the decolorization process. © 2016 Society of Chemical Industry

“…Toxicity effects of Cd as pronounced in liquid media drastically diminish in the presence of soils, organic matter, and high concentrations of dissolved salts [116]. In the solid-state fermentation of rice straw with the basidiomycete Phanerochaete chrysosporium, Cd halved the activities of lignin peroxidase at 4 mg·kg −1 DW and of manganese peroxidase at 6 mg·kg −1 ; it also halved the degradation of lignin at 16 mg·kg −1 , and of cellulose and hemicellulose at about 32 mg·kg −1 [115]. The weight loss of straw incubated with P. chrysosporium was optimum at Pb concentrations of 30 mg·kg −1 , but proceeded, too, at 400 mg·kg −1 [117].…”

“…However, the fungi used in the preparatory delignification of the biomass feedstock for bioethanol production face the full toxicity of internal HM. The resulting oxidative stress leads to the damage of cellular biomolecules such as DNA, lipids, and proteins by reactive oxygen species and may result in cell death [110][111][112] and restrictions in mycelial growth, enzymatic activity, and the rate of substrate conversion [113][114][115]. Toxicity effects of Cd as pronounced in liquid media drastically diminish in the presence of soils, organic matter, and high concentrations of dissolved salts [116].…”

Abstract:Testing the quality of heavy-metal (HM) excluder plants from non-remediable metalliferous soils could help to meet the growing demands for food, forage, and industrial crops. Field cultures of the winter wheat cv. JB Asano were therefore established on re-cultivated uranium mine soil (A) and the adjacent non-contaminated soil (C). Twenty elements were determined by Inductively Coupled Plasma Mass Spectrometry (ICP-MS) from soils and plant sections of post-winter seedlings, anthesis-state, and mature plants to record within-plant levels of essential and toxic minerals during ripening and to estimate the (re)use of the soil-A herbage in husbandry and in HM-sensitive fermentations. Non-permissible HM loads (mg·kg −1 ·DW) of soil A in Cd, Cu, and Zn of 40.4, 261, and 2890, respectively, initiated the corresponding phytotoxic concentrations in roots and of Zn in shoots from the seedling state to maturity as well as of Cd in the foliage of seedlings. At anthesis, shoot concentrations in Ca, Cd, Fe, Mg, Mn, and Zn and in As, Cr, Pb, and U had fallen to a mean of 20% to increase to 46% during maturation. The respective shoot concentrations in C-grown plants diminished from anthesis (50%) to maturity (27%). They were drastically up/down-regulated at the rachis-grain interface to compose the genetically determined metallome of the grain during mineral relocations from adjacent sink tissues. Soil A caused yield losses of straw and grain down to 47.7% and 39.5%, respectively. Nevertheless, pronounced HM excluder properties made Cd concentrations of 1.6-3.08 in straw and 1.2 in grains the only factors that violated hygiene guidelines of forage (1). It is estimated that grains and the less-contaminated green herbage from soil A may serve as forage supplement. Applying soil A grains up to 3 and 12 in Cd and Cu, respectively, and the mature straw as bioenergy feedstock could impair the efficacy of ethanol fermentation by Saccharomyces cerevisiae.
