In this lesson, we will study the importance of cellulose in the biological world. Cellulose is an indispensable part of a plant cell wall and an excellent source of food and energy for microbes. solved by a focused research concerning efficient methods applied in biological degradation processes. In this respect, the scope of this chapter is to present the state of the art concerning the biodegradation of redundant cellulose wastes from agriculture and food.

degradation can enhance the enzymatic reactions utilized in biodegradation. In special formulations photo degradation can be used for the complete degradation of a cellulose acetate material. Chemical degradation Cellulose acetate polymer is chemically degraded by a process called hydrolysis, which means breaking apart by the addition of water (9).File Size: KB. Wood is decomposed by a variety of biological agents, including fungi, bacteria, and insects. Fungi colonize wood and degrade cell wall components to form brown, soft, or white rot. Brown-rot fungi, which degrade primarily the polysaccharide components of wood, leave a lignin framework. White-rot fungi may degrade all cell wall components.

This topic has received much attention of late because of. The degradation rate of many organic compounds is limited by their bioavailability, which is the rate at which a substance is absorbed into a system or made available at the site of physiological activity, as compounds must be released into solution before organisms can degrade rate of biodegradation can be measured in a number of ways.

Cellulose decomposition in soils did not show age-dependent variation, but decreased with depth. The microbial biomass gave similar values in each layer of each soil. It is evident from these findings that dehydrogenase activity was a more sensitive biological parameter than cellulose decomposition or microbial biomass.

Lignin forms the woody cell walls of plants and the cement material between the plant walls, and after cellulose, it is the second most abundant biopolymer in the world. This book examines the biochemistry of lignin formation, lignin modification and utilization as a polymer, lignin in pulping and bleaching, chemical and physical properties of lignin, and lignin biodegradation.

Microbial biodegradation is the use of bioremediation and biotransformation methods to harness the naturally occurring ability of microbial xenobiotic metabolism to degrade, transform or accumulate environmental pollutants, including hydrocarbons (e.g.

oil), polychlorinated biphenyls (PCBs), polyaromatic hydrocarbons (PAHs), heterocyclic compounds (such as pyridine or quinoline. The main biological function lies in the synergism of fungal LPMOs with canonical hydrolytic cellulases in achieving efficient cellulose degradation.
