This book results from the cooperative work of a group of experts convened by the IAEA in October The aim of the book is to provide state of the art knowledge on application of radiation technology for disinfection and consolidation. It is addressed to the conservation community (curators. The objectives of this book are twofold: 1. To provide a thorough examination of the materials science of cellulosic fibers with emphasis on the characterization of structure-property relations, and 2. To advance knowledge of how to best analyze cellulosic fibrous networks and composites, and, ultimately, engineer "novel" cellulose-based systems of superior performance and functionality.

crucial for librarians and specialists in libraries and information centers [2]. Biodegradation and biodeterioration of paper-made materials is a worldwide problem that causes great damage to unique manuscripts and books stored in libraries (Fig. 1). The basic component of paper is cellulose; however, other constituents like starch, sugar. A feedstock containing a biomass such as lignocellulosic materials, e.g. forest biomass; agricultural residues; or manures, is pretreated and thereafter is fractionated into cellulose, lignin and hemicelluloses. New mutants are disclosed which include Chaetomium cellulolyticum IAF (NRRL ), Aspergillus sp. IAF (NRRL ), Penicillum sp. IAF (NRRL ), and .

Chaetomium cellulolyticum, a newly isolated cellulolytic fungus, showed 50–% faster growth rates and over 80% more final biomass‐protein formation than Trichoderma viride, a well‐known high cellulase‐producing cellulolytic organism, when cultivated on Solka‐floc (a purified, predominantly amorphorous form of cellulose) or partially delignified sawdust (consisting of a mixture of Cited by:   The book concludes with an overview of the mode of action of the enzymes and a discussion, citing a few examples, of how the modern methods of molecular biology, enzymology, and X-ray crystallography are being used to manipulate selected enzymes for a variety of biotechnological and industrial by: The book concludes with an overview of the mode of action of the enzymes and a discussion, citing a few examples, of how the modern methods of molecular biology, enzymology, and X-ray crystallography are being used to manipulate selected enzymes for a variety of biotechnological and industrial purposes.

lulosic materials (15, 34, 52). Biochemical studies performed on related, nonendophytic species, i.e., Chaetomium cellulolyticum Chahal and Hawksworth and Chaetomium erraticum Ames, re-vealed that a small number of enzymes are part of the core of the cellulase complex, namely, three endoglucanases and one -glu-cosidase (4, 52).

Almost half of the biomass synthesized by photosynthetic fixation of carbon dioxide is made up of cellulose. Cotton and wood fibers are the most common sources. It makes up for about 90% of cotton fibers but for only about 45% of the average wood fiber. Biological material and experimental plan.

Chaetomium globosum was detected endophytically in nonsymptomatic foliar tissues of Vitis vinifera plants of both the “Cabernet Sauvignon” and “Chardonnay” cultivars, collected in northern Italy during two vegetative seasons ( to ).

The strain was isolated following the procedure of Cardinali et al. (), which was already tested in a. in slow biodegradation rates of cellulosic materials. To divert fabric waste from landfills, an alternative method of fabric disposal would be application of cellulosic fabric waste to surface soil where aerobic conditions could result in enhanced biodegradation rates.

Information on cellulosic fabric biodegradation. AMEEN et al.: BIODEGRADATION OF CELLULOSIC MATERIAL BY FUNGI focused on bacteria, but a few studies have shown that pollutants could be degraded in soil by fungi Fungi are well known to degrade, or cause deterioration to, a wide variety of materials and compounds, processes known as mycodegradation and mycodeterioration, respectively The mycoprotein production data on several types of cellulosic materials (sugarcane bagasse, corn stover, wood cellulose) are presented.

The performance of N. sitophila is found to compare favourably with that of Chaetomium cellulolyticum, another cellulolytic organism previously reported on by us. In the present technoeconomic era, the energy and environmental crises developed due to huge amount of cellulosic materials are disposed as “waste.” Municipal solid waste is composed of 40–50% cellulose, 9–12% hemicelluloses, and 10–15% lignin on a dry weight basis [1, 2].

The genus Chaetomium was found to be associated with all specimens. Cellulosic materials have played an important role in everyday life as constituent of wood, paper, cloth, rayon film, plastic rope and fillers. The Carboxymethyl Cellulose (CMC), a derivative of cellulose is produced by chemical modification of cellulose, the most abundant polymer in nature and a major component of wood and cotton.
