“…Fungi are well-known agents of decomposition of organic matter in general and of cellulosic substrates in particular (94,462). Fungal taxonomy is based largely on the morphology of mycelia and reproductive structures during various stages of the fungal life cycle rather than on substrate utilization capability.…”

Fundamental features of microbial cellulose utilization are examined at successively higher levels of aggregation encompassing the structure and composition of cellulosic biomass, taxonomic diversity, cellulase enzyme systems, molecular biology of cellulase enzymes, physiology of cellulolytic microorganisms, ecological aspects of cellulase-degrading communities, and rate-limiting factors in nature. The methodological basis for studying microbial cellulose utilization is considered relative to quantification of cells and enzymes in the presence of solid substrates as well as apparatus and analysis for cellulose-grown continuous cultures. Quantitative description of cellulose hydrolysis is addressed with respect to adsorption of cellulase enzymes, rates of enzymatic hydrolysis, bioenergetics of microbial cellulose utilization, kinetics of microbial cellulose utilization, and contrasting features compared to soluble substrate kinetics. A biological perspective on processing cellulosic biomass is presented, including features of pretreated substrates and alternative process configurations. Organism development is considered for “consolidated bioprocessing” (CBP), in which the production of cellulolytic enzymes, hydrolysis of biomass, and fermentation of resulting sugars to desired products occur in one step. Two organism development strategies for CBP are examined: (i) improve product yield and tolerance in microorganisms able to utilize cellulose, or (ii) express a heterologous system for cellulose hydrolysis and utilization in microorganisms that exhibit high product yield and tolerance. A concluding discussion identifies unresolved issues pertaining to microbial cellulose utilization, suggests approaches by which such issues might be resolved, and contrasts a microbially oriented cellulose hydrolysis paradigm to the more conventional enzymatically oriented paradigm in both fundamental and applied contexts

“…Cellulose fibres consist of biopolymers which are highly susceptible to microbial degradation (Desai and Pandey 1971;Montegut et al 1991;Allen et al 1995;Itävaara et al 1999;Salerno-Kochan and Szostak-Kotowa 2001;Park et al 2004). Though biodegradibility is desirable in degradation processes of waste material, it is a great disadvantage for textile products which are still in use.…”

Surface properties of cellulose modified by imidazolidinone

et al. 2007

The influence of the modification of cellulose fibres by the imidazolidinone derivative 1,3-dimethyl-4,5-dihydroxyethylene urea (DMeD-HEU) on fibre surface free energy and electrochemical potential was studied. The presence of DMeDHEU in the cellulose structure was confirmed by infrared spectral analysis. The surface free energy of untreated and treated cellulose fibres was determined from the results of thin-layer wicking, where the rate of liquid penetration into the cellulose fabric was measured. Using the van Oss-Chaudhury-Good theoretical approach, apolar, c S LW , polar electron-acceptor, c S + , and electron-donor, c S À , components of the surface free energy were calculated. The electrokinetic potential was determined from the results of steaming potential measurements. The results revealed that the incorporation of DMeDHEU into the cellulose structure lead to a decrease in the value of c S À , whereas the values of c S LW and c S + remained almost unchanged. Despite their decreased c S À value, the treated cellulose fibres still represent a monopolar solid with a strongly expressed electron-donor component. The values of DG iw and DG iwi suggested that both untreated and treated cellulose samples could be considered hydrophilic substrates. The results of the electrokinetic potential measurements showed that the consumption of cellulose hydroxyl groups in the crosslinking reaction with DMeDHEU did not decrease the electrokinetic properties of the cellulose surface.

“…In public discussion the presence of EHEC germs in water and on fruits is also one topic which makes clear that hygienic and antimicrobial surfaces could be highly advantageous (Fröhlingsdorf et al 2011;Krischer et al 2011). The material protection is mainly related to materials from natural resources as, e.g., wood, paper, or natural textile fibers (Donath et al 2006;Montegut et al 1991). These materials can be destructed by microbes, so an antimicrobial sol-gel coating could expand the lifetime of such materials significantly.…”
