          Abstract

          Industrial biotechnology has the potential to fulfil many key criteria of greener textile production. This review outlines the current research and future directions of the emerging applications of enzymatic technology in the sustainable production and processing of textiles. The state-of-the-art industrial enzymes in textile processing include amylases for desizing of cotton and cellulases for denim-washing and biopolishing. Aside from these established processes, emerging enzymatic processes such as cotton scouring and bleaching, bast fiber retting/degumming, wool scouring and shrink-proofing, silk degumming, bio-dye production and enzyme-assisted dyeing and finishing are at various stages of development. To illustrate the state-of-the-art, representative examples of enzymes in the processing of various types of textile substrates are discussed and evaluated in this article. The major limitations of the large scale implications of textile biotechnology are lack of sufficient research efforts to make it an economically viable option and issues related to technological glitches. The limitations of existing approaches will be highlighted and the requirements of continuous improvement to overcome current obstacles will be demonstrated by critical assessment.

          Industrial enzyme applications.

          The effective catalytic properties of enzymes have already promoted their introduction into several industrial products and processes. Recent developments in biotechnology, particularly in areas such as protein engineering and directed evolution, have provided important tools for the efficient development of new enzymes. This has resulted in the development of enzymes with improved properties for established technical applications and in the production of new enzymes tailor-made for entirely new areas of application where enzymes have not previously been used.

            Microbial Cellulases and Their Industrial Applications

            Microbial cellulases have shown their potential application in various industries including pulp and paper, textile, laundry, biofuel production, food and feed industry, brewing, and agriculture. Due to the complexity of enzyme system and immense industrial potential, cellulases have been a potential candidate for research by both the academic and industrial research groups. Nowadays, significant attentions have been devoted to the current knowledge of cellulase production and the challenges in cellulase research especially in the direction of improving the process economics of various industries. Scientific and technological developments and the future prospects for application of cellulases in different industries are discussed in this paper.

              Industrial applications of enzyme biocatalysis: Current status and future aspects.

              Enzymes are the most proficient catalysts, offering much more competitive processes compared to chemical catalysts. The number of industrial applications for enzymes has exploded in recent years, mainly owing to advances in protein engineering technology and environmental and economic necessities. Herein, we review recent progress in enzyme biocatalysis, and discuss the trends and strategies that are leading to broader industrial enzyme applications. The challenges and opportunities in developing biocatalytic processes are also discussed.
