Therefore termites have to solve the “carbon-nitrogen balance” problem in addition to “, Soil Microbiology, Ecology and Biochemistry (Fourth Edition), ), the decomposition of cellulose is a key activity of soil bacteria and is vital to the energy flow through soils and the cycling of N, P, and S, where immobilization generally accompanies, Large-Scale Ecology: Model Systems to Global Perspectives. (2013) provides a good overview of the structural and biochemical basis for cellulose biodegradation. The action is essential for the dead matter to be managed. 3.9. Exogluconases are a group of exocellulase that hydrolyze the reducing or non-reducing ends of the cellulose chains. microbial decomposition to the presence of heavy metals is often substrate dependent, e.g. ). Also, when almond shells and potato skins were copyrolyzed with high-density polyethylene, the properties of the oil yield resembled fossil diesel in terms of H:C ratio and heating values. At the regional scale, several programmes have been initiated by river basin agencies, including those for the Loire-Bretagne and Adour-Garonne. Summary of Literature Studies Reporting Thermochemical Conversion of Plant-Sourced Food Waste and Residues. When thermochemical conversion of biomass is considered, the type of feedstock and the desired end products are essential to know for selecting the most efficient conversion technology. The molecular weight of cellulose ranges between 200,000 and 2,000,000, thus corresponding to 1,250–12,500 glucose residues per molecule. Cellulose degradation occurs within the temperature range of 0°C, and 65°C as both psychrophilic and thermophilic organisms are capable of hydrolyzing cellulose. Lignin primary structures and dirigent sites. One of the basic conditions for coalbed biomethane production is the presence of anaerobic bacteria in the coalbed. In the first step, the nucleophile attacks the anomeric center, resulting in deprotonation. Under the acidic condition, fungi are the primary group of organisms involved in cellulose decomposition, whereas bacteria and actinomycetes act as dominant cellulose decomposers in neutral to alkaline conditions. The remaining solid waste also can be converted into high surface area activated carbon, which showed promising absorption ability, but further research is needed (Goldfarb et al., 2017; Buessing, 2012). Cellobiose phosphorylases are similar to cellobiases except that the hydrolysis of polymeric units is brought about in the presence of phosphorus rather than water. Lignin primary structures and dirigent sites. The decomposition of cellulose is a relatively specialized depolymerization exercise (involving a restricted number of saprophytes) followed by hydrolysis to glucose, which is rapidly utilized as an energy source by most heterotrophic soil microorganisms. In addition, thermal decomposition with TGA analysis showed two distinct peaks for hemicellulose (first) and cellulose (second) decomposition steps which differ from the TGA analysis of other woody biomass species that generally result in one overlapping peak (Table 8.4) (Tsamba et al., 2006). On the other hand, separate type termites that are free from the limit in resource utilization are expected to make a full choice among possible mechanisms for C-N balance, including association with methanogenic bacteria. This seems reasonable because they have no way to gain glucose, which is used not only for energy production but also for biological synthesis, other than digesting cellulose for themselves. In anaerobic environments rich in decaying plant material, the decomposition of cellulose is brought about by complex communities of interacting microorganisms. On the other hand, C-N balance symbiosis is necessary for all termites, because they are not able to solve the problem alone. Volume 79, 2016. There are about five types of cellulases on the basis of the reactions they catalyzed. Aerobic hydrolysis is fairly simple and occurs in sequential steps, each of the steps catalyzed by a different type of cellulase enzyme. The research demonstrated that the upgraded oil could potentially be used to displace fossil-based fuel (Abnisa et al., 2011, 2013). Even though most aerobic bacteria degrade cellulose by the synergistic action of different cellulases, some cell-free cellulolytic fungal culture filtrates degrade cellulose faster in an oxygen atmosphere than under anaerobic conditions. dam removal, remeandering, pond disconnection and sedimentary recharge (Colas et al., 2016). The cellulase enzyme complex, which catalyzes cellulose decomposition, occurs in a large number of cellulolytic bacteria (species of Bacillus, Pseudomonas, Streptomyces, and Clostridium; Coughlan and Mayer, 1992) and fungi and operates via a two-stage process. Although insoluble in water, cellulose absorbs water and adds to the bulk of the fecal matter, and facilitates its removal. The cellulose polymer (molecular weight approximately 1 million) occurs in plant residues in a semicrystalline state and consists of glucose units joined by β-1,4 linkages, with chains held together by hydrogen bonding (Fig. Strapoc et al. Even if the human body cannot digest cellulose, it acts as a source of fiber. Acta Biotechnol., 3: 65-72. Cellulose-decomposing bacteria were less frequent, with abundance ranging from 4% to 15%. 2006) E.g. Studies of catalytic pyrolysis of cotton cocoon shell, olive husk, and tea factory waste concluded that total hydrogen-rich gaseous products increased with increasing pyrolysis temperature. Bacteria associated with dead fungal mycelium were important during initial decomposition, with sequence relative abundances of up to 40% of the total bacterial community in months 2 and 4 when the highest fungal biomass was observed.
