“…These values stand out in relation to the values found by Jonas and Farah, 28 where the culture medium containing mannitol produced 3.8 times more BC than glucose. These results disagree with the results found by Jung et al, 29 who did not consider glycerol as a good carbon source for bacterial cellulose production using G. xylinum.…”

Production of bacterial cellulose (BC) by Gluconacetobacter xylinus was investigated in static culture form, using glycerol and biodiesel residue as the carbon sources and as raw material for technological purposes. The cellulosic material, obtained as a membrane, was characterized by spectroscopic techniques and its morphological aspects were investigated by scanning electron microscopy (SEM). In a medium containing 3% (w/v) glycerol, the BC yield was higher than that from a glucose and mannitol based-medium. After 10 days, using a medium containing biodiesel residue, we obtained a satisfactory amount of BC. FT-IR spectra revealed that all the BC samples showed characteristic peaks, associated with the usual functional groups for this cellulosic material. These results suggested that glycerol could be a potential low-cost substrate for BC industrial scale production, based on its high performance and economic viability.

“…In general, glucose has been used as a carbon source for cellulose production by Acetobacter xylinum. It has been reported, however, that cellulose was also synthesized from other carbon sources, such monosaccharides, oligosaccharides, starch, alcohol and organic acids [69]- [73]. Fructose and glycerol gave almost the same cellulose yield as glucose [74].…”

In recent years, several studies have been performed using nanocellulose as a component in polymeric nanocomposites. The interest in studying cellulose-based nanocomposite is due to the abundance, renewable nature, and outstanding mechanical properties of this nanoparticle. However, obtaining nanocomposites based on nanocellulose, with optimal properties, requires good nanoparticle dispersion in the polymeric matrix. The chemical compatibility between nanofiller and polymer plays a major role in both the dispersion of particles in the matrix and the adhesion between these phases. The aim of this review is to present the fundamental concepts about nanocellulose, such as its structural aspects, production methods and current trends in classification, and the main aspects about cellulose-based nanocomposites, including the progress that has been reached in relation to their compatibilization, production, final properties and potential applications. F. A. dos Santos et al. 258 properties such as biodegradability, biocompatibility, low toxicity, and low cost among others [4]. These properties provide a great potential for use in applications from plastic bags and packaging to biomedical fields, including bone plates, fixation screws or sutures. However, to replace petroleum-based thermoplastics, biopolymers need to have comparable properties and processing methods to those conventionally used. In order to improve their properties, many biopolymers have been used in the preparation of nanocomposites [1].Similar to conventional composites, nanocomposites are composed of at least two components; one of them is the matrix or continuous phase, in which nanosized particles are dispersed. These nanosized particles or nanoparticles constitute the second phase, referred to as the dispersed phase. Polymer nanocomposites are a recent alternative to conventionally filled polymers. Due to the reduced size of dispersed phase and its good dispersion in the polymer matrix, these materials exhibit markedly improved properties when compared to the pure polymers or their traditional composites [5]. They also exhibit unique optical, electrical, and magnetic properties [6].Biopolymers, such as chitin, starch, and cellulose, can be employed as reinforcement filler or as matrix in the production of nanocomposites [2]. Cellulose is one of the best natural materials to generate nanofillers for producing nanocomposites that are based on renewable raw material sources, because it is the most abundant biopolymer in nature and is available in a wide variety of resources, such as plants and microorganisms [7]- [11].The nanofillers isolated from cellulose have been used as a reinforcing material in many natural and synthetic polymers [12]- [18]. The use of these nanofillers has proven effective due to the large surface area and the excellent mechanical properties presented by cellulose [19]. Furthermore, the addition of cellulose-based nanofillers promotes a better performance of the nanocomposite in relation to their barrier, thermal and mech...

“…The bands at 715 cm-1 show the possibilities C-O-C functionalities present in the BC. According to Jung et al (Jung et al .,2010) who reported that the IR spectrum of BC produced in molasses medium is observed in the region of 3240 cm-1 , attributing to the presence of more quantities of cellulose Iα. Our results ( Figure 1A) indicated that the transmittance peak near to 3240 cm-1is achieved, indicating that cellulose Iα is abundantly present in the BC produced in HS medium.…”
