About this Research Topic
The immeasurable release of contaminants such as azo dyes, heavy metals, and plastics by industries and factories is posing life-threatening perils to the environment. Dyes, commonly known as colored effluents, are emitted from various textile, pharmaceutical, and food industries. During the manufacturing of dyes by these industries, a large amount of the product is wasted and adulterates water bodies. These dyes contaminate the natural drinking water, harming human sight, and increasing the incidence of skin cancers among the population.
The textile industry is the major source of contamination of water bodies due to the release of azo dyes. Azo dyes are chemical compounds containing double bonded Nitrogen atoms (-N=N-), making them recalcitrant and causing irreparable harm to the environment. The after-effects include the aggravation of Biological Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) which results in shrinkage of the photosynthesis rate, leading to stunted plant growth and the collapse of the whole food chain. The use of natural sources, including microorganisms such as bacteria, fungi, and algae, to reclaim the natural environment and resources is highly recommended. The harboring of multiple degradation strategies makes these microorganisms an impending foundation for green chemistry to exterminate toxic azo dyes from the environment.
This article collection welcomes high-quality works, including (but not limited to) the following themes:
• Sources and toxicity of azo dyes against living organisms
• Impact of optimized conditions on azo dyes degradation
• Enzymes, and metabolic pathways involved in azo dyes degradation
• Evaluation of toxicity of azo dyes degraded products for environmental safety
• Emerging technologies valuable in microbial/fungal degradation of azo dyes
