Abstract
Catalases are hydroperoxidases with numerous industrial applications. In textile industry, these enzymes efficiently remove hydrogen peroxide residues from bleached cotton fabrics. The commercial catalases used in the textile industry are either heme-catalases or catalase-peroxidases, which are thermolabile. Thermostable manganese-catalases represent a promising, yet unexplored alternative for this purpose. The present study explores the potential of three manganese-catalases (CatGt, Cat-IIGt, CatGt-ΔC) from Geobacillus thermopakistaniensis for bleach clean-up process. These enzymes demonstrated superior performance to the commercial enzymes. Notably, Cat-IIGt emerged as the most effective, offering significant advantages due to its high activity, thermostability, and alkaline nature. This enzyme can be directly added to the bleach bath, thereby reducing water consumption without compromising subsequent processes. To the best of our knowledge, this is the first report on applications of manganese-catalases, a less explored class, in the textile industry.
期刊介绍:
International Journal of Environmental Science and Technology (IJEST) is an international scholarly refereed research journal which aims to promote the theory and practice of environmental science and technology, innovation, engineering and management.
A broad outline of the journal''s scope includes: peer reviewed original research articles, case and technical reports, reviews and analyses papers, short communications and notes to the editor, in interdisciplinary information on the practice and status of research in environmental science and technology, both natural and man made.
The main aspects of research areas include, but are not exclusive to; environmental chemistry and biology, environments pollution control and abatement technology, transport and fate of pollutants in the environment, concentrations and dispersion of wastes in air, water, and soil, point and non-point sources pollution, heavy metals and organic compounds in the environment, atmospheric pollutants and trace gases, solid and hazardous waste management; soil biodegradation and bioremediation of contaminated sites; environmental impact assessment, industrial ecology, ecological and human risk assessment; improved energy management and auditing efficiency and environmental standards and criteria.
