“…Using crude extract as a cheaper enzyme preparation in an optimised process, up to 71% of colour-stripping of uneven-dyed fabric could be achieved. There are reports for using crude enzyme extracts for dye decolourisation [28]. In contrast, in other reports, purified and specifically characterised preparation of enzymes were used for dye decolourisation and hydrolysis of straw [29,30].…”

This article aims to provide information on two aspects: firstly, waste management of residual biological agro-industrial materials generated from agriculture, and secondly, for the sustainable remediation of textile wastewater. Annually, huge amounts of solid renewable biomass materials are generated worldwide from agricultural and farming sectors. The generation of these vast amounts of solid wastes could be utilised as a valuable and renewable natural resource for various applications. The goal of promoting sustainable development has increased the interest in recycling wastes economically and in an eco-friendly way. This article reviews the published research on this topic and discusses the usage of these solid substrates in the remediation of a major environmental component, textile dye-contaminated water. The purpose of this article is to discuss an integrated and cross-disciplinary approach to sustainable solid and liquid waste management and remediation of environmental components and to report the biological approaches and their efficiency in a chemical-free and economically viable bioremediation process for large volumes of dye-contaminated water resources.

Recently there is a great social expectation that scientists should produce more sustainable and environmentally friendly chemical processes. Within this necessity, biocatalysis presents many attractive features because reactions are often performed in water, under mild conditions, the catalyst is biodegradable and can be obtained from renewable raw materials. In this work, we propose a simple, rapid and low-cost method for the preparation and application of an enzymatic extract from turnip root. The protocol described includes (1) the preparation of the enzymatic extract, (2) the procedure for the assessment of the more favorable working parameters (temperature, pH) and (3) the methodology for the application of the extract as the catalyst for biotransformation reactions. We anticipate that the protocol in this research will provide a simple way for obtaining an enzymatic extract which can operate efficiently under mild conditions and can effectively catalyze the biotransformation of simple phenols.

“…The microbial enzymes, such as depolymerase, esterase and lignolytic ones, that cleave the polymers in small chain compounds, may be involved in the plastics degradation [6,13,18,19]. Thus, white rot fungi have a great potential, because they are enzymes producers and have shown their ability for treatment of industrial waste [20][21][22].…”

The studies on plastic degradation are very important for the development of biodegradable plastics, and for reduction of pollution, since plastic waste can remain in the environment for decades or centuries. We have showed the degradation of oxo-biodegradable plastic bags and green polyethylene by Pleurotus ostreatus. This fungus can also produce mushrooms using these plastics. The plastic degradation was possibly by three reasons: (a) presence of pro-oxidant ions or plant polymer, (b) low specificity of the lignocellulolytic enzymes, and (c) the presence of endomycotic nitrogen-fixing microorganisms. In this chapter, the plastic bags' degradation by abiotic and microbial process using the exposure to sunlight and the use of a white-rot fungus will described. The physical, chemical, and biological alterations of plastic were analyzed after each process of degradation. The degradation of plastic bags was more effective when the abiotic and biotic degradations were combined.
