“…34 Fungi generally require acidic pH but Actinomycetes and bacteria require neutral or alkaline pH optima for xylanase production. Trichoderma reesei (Tenkanen et al 1992) 82 Thermomyces (Bajpai 1999) 5 , Aureobasidium pullulans (Christov et al, 1999) 22 . B. subtilis (Wilson et al, 1999) are some of the strain for xylanase production at commercial level.…”

“…93 Due to their Industrial potential, microbial xylanolytic enzymes have drawn a great attention in the last decade. The most promising and wide spread use of Xylanase is in the prebleaching of kraft pulps (Bajpai 1999 20 have also been reported to improve the delignification of unbleached kraft pulps. Xylanases produced by many alkali tolerant strains having pH optima around 9 have been used for bio bleaching.…”

Xylanases have a great potential, mainly known for industrial applications. They can hydrolyze the xylose (Hemicellulose of plant cell wall) and can be used for bio-bleaching the kraft pulp. As it reduces the requirement of harsh chemicals in the process, it can be used further to a number of bio-products with a great aggregate value. Microbial-origin xylanases can also be used in improving the nutritional quality of animal feed (e.g. food additives to poultry, piggery or fishery) and indirectly affect the humans. Additionally they can be used directly in human food in bakery, clarification of juices and in xenobiotics like tobacco processing. The great value of xylanase as a bio-bleaching agent has now a new dimension of fiber digesting agent having relevance to food, drugs and cosmetics act. This review presents some important applications of Xylanases extended up to biomedical sciences. [Int J Basic Clin Pharmacol 2013; 2(3.000): 237-246

The global pulp and paper industry is in physical terms one of the largest industries in the world. It is traditionally known to be a large contributor to environmental pollution owing to its large consumptions of water, energy, and chemicals. Biotechnological methods offer potential opportunities for changing the industry toward more environmentally friendly and efficient operations compared to the traditional methods. Biotechnological processes are environmentally friendly, energy efficient, more specific, and can be used in place of nonbiological processes. The use of biotechnological processes in the pulp and paper industry results in increased pulp yield, improved fiber properties, enhanced paper recycling, reduced processing and environmental problems, and energy efficiency. Many applications of biotechnology in the pulp and paper industry have been commercialized and some are on the verge of commercialization. Applications that have been commercialized are the use of xylanases for bleaching, cellulase‐hemicellulase mixture for fiber modification and deinking, cellulases for improved drainage, lipases for pitch removal, esterases for stickies control, levan hydrolase, proteases, cellulases, and amylases, etc., for slime removal. Many new applications are being studied that include new enzymatic approaches to reduce mechanical pulping energy, new enzymes for kraft pulp bleaching, enzyme sensors for smart paper products, etc. Bio‐based unit operations are usually combined with conventional or new chemical and mechanical unit operations to fully benefit the performance of enzymes. This chapter provides general background on pulp and paper processing and describes the use of microbes/enzymes in each of the processing areas.
