“…In addition, there is the possibility of producing CNSs from a multitude of sustainable, widely available and lowcost resources such as forest residues (wood saw-dust -pine and eucalyptus), agricultural (wheat straw, sugar cane) and industrial (cotton waste, paper waste, and tobacco industry) [2,[8][9][10][11][12]. CNSs can be applied in a variety of areas, such as electronic displays, paints, packaging, membranes, implants, polymer composites and others [13]. The application is highly dependent on the nanocellulose properties and its surface chemistry [14].…”

This work aimed to evaluate three different milling conditions, seeking the optimization of CNS isolation process. The paper sludge was chemically treated with detergent and H 2 O 2, by two steps, to remove the noncellulosic contents (hemicellulose and lignin). After these treatments, the sample was milled with the variation of a liquid medium. The three liquids milling medium were: i) dry medium (CNS-D); ii) moist with water and (CNS-W) iii) moist with ethanol (CNS-E). The CNSs were characterized by Fourier transform infrared spectroscopy (FTIR), thermogravimetric analysis (TGA), scanning electron microscopy (SEM), zeta potential and dynamic light scattering (DLS). The milled samples presented different behavior, depending on the medium applied. The CNS-W presented low efficiency due to the formation of agglomerates around the ceramic ball, resulting in larger fiber sizes (microsizes). Although, the samples CNS-D and CNS-E presented similar behavior of sizes distribution, with average size 340 nm and 373 nm, respectively, determined by DLS. The CNS-E sample presented higher yield and electrostatic stability in solution, besides not presenting loss of crystallinity, as occurred with CNS-D, observed by FTIR analysis. Thus, the isolation with ethanol showed more efficient process among the three processes studied. This work achieved the isolation of CNS; besides, it proposed an environmentally friendly isolation method, and this may add value in the paper sludge.

“…The lowest BC production by K. rhaeticus K23 was recorded at 26 • C and the maximum production was obtained at 32 • C (Figure 3). Many researchers have found that the optimum growth temperature for biocellulose production is 30 • C [38][39][40][41]. However, this may be due to the strains which they used in their studies (Acetobacter sp.…”

The use of bacterial cellulose (BC), having high purity, a high degree of crystallinity, water-holding capacity, tensile strength and adaptability on a broad scale is limited because of the low yield. In this study, the optimal conditions for bio-cellulose production by Komagataeibacter rhaeticus K23 were investigated. Optimal values for temperature, pH, inoculum concentration and incubation time were determined via Taguchi design. The maximum BC production, 9.1 ± 0.66 g·L−1 (dry weight), was obtained from 32 °C, pH 5.5, 8 log CFU·mL−1 and 14 days of incubation. The inoculum concentration was the most significant factor affecting BC yield. A value of 8 log CFU·mL−1 and 14 days of incubation led to significantly higher levels of BC yield than other concentrations (8.5, 9, 9.5, 10 and 10.5 log CFU·mL−1) (p < 0.002) and days (15, 16, 17, 21 and 28) (p < 0.001). The studied features, namely absorption peaks (Fourier transform infrared spectroscopy), pattern and the crystallinity index (X-ray diffraction analysis) of the BC obtained in this study were all in parallel with the characteristics of cellulose I. The study demonstrates that optimized parameters were effective in producing BC with high water-holding capacity, tensile strength, elongation and Young’s modulus (mechanical tests) by K. rhaeticus K23.

“…The lack of consistency in nomenclature has cost plenty of efforts to search, understand, and cross-check different materials. The terms that have been used include cellulose nanocrystal [25], cellulose nano-crystal [26], cellulose nanocrystalline [27], crystalline cellulose nanofibril [28], nano-fiber [29] nano-cellulose [30] nanocrystalline cellulose [31], cellulose nanofibril [20], nanofibrillated cellulose [6], nanofibrillar cellulose [32], nano-fibrillated cellulose [33], cellulose nanofiber [34]. The subjective use of different terms for the same material may lead to confusion, misunderstanding, and miscommunication in this domain area, Cao -eXPRESS Polymer Letters Vol.12, No.9 (2018) and therefore it is crucial to standardize the terminology.…”
