One-step production of nanofibrillated bacterial cellulose (NFBC) from waste glycerol using Gluconacetobacter intermedius NEDO-01

Production of nano bacterial cellulose from beverage industrial waste of citrus peel and pomace using Komagataeibacter xylinus

“…It had three characteristic peaks at 12.517 °--18.869 °, 20.753 °--25.982 °, and 30.101 °--30.820 °, while the grain sizes were 55 nm, 57 nm and 456 nm, respectively. In contrast to the literature (Kose, Sunagawa, Yoshida & Tajima, 2013), the analysis of BC in the CPPE medium (black curve) showed two peaks at 11.988°--18.187° and 20.101°--25.589°, while the grain sizes were 45 nm and 56 nm, respectively. This implies that the determination of the crystallinity index resulting from the different media could be from hydrogen bonding between the cellulose chains, which were almost the same as BC produced from other waste feedstock (Li, Wang, Hua, Jia, Zhang & Liu, 2015;Zhang, 2013).…”

“…Use of different carbon sources Addition of components to the agitated culture Non-linear dependence of DP from harvesting time was observed by Shi et al (2012a) Fermentation in trickling reactor results in higher DP (Lu and Jiang, 2014) Glucose as a carbon source results in a higher DP in comparison with glycerin and xylose (Shi et al, 2012a) Waste glycerol medium supplemented with carboxymethylcellu lose leads to the formation of nanofibrillated cellulose (Kose et al, 2013) (Yoshida et al, 2012) Improved interaction of BC with aminocontaining materials (e.g. collagen) (Saska et al, 2012) Ethyl-, propyl-, i-propyl-, nbutyl BC derivatives with better solubility in low polar solvents (Lin et al, 2013b) Improved water solubility (Geyer et al, 1994) Improved protein adsorption (Lin et al, 2015) Hydrophobizat ion of BC surface Active site for further modifications Carbon reactivity: C(6)>>C (2) (Luo et al, 2014b) Shaking conditions result in thinner and longer BC fibers (Mohite and Patil, 2014) 50% loss in fiber diameter (Grande et al, 2009a) Increased microfibril diameter (Ha et al, 2011) Composite with suitable electrical properties (Luo et al, 2014a) Scaffold with improved biocompatibility for bone regeneration (Grande et al, 2009a) Material adsorbent for heavy metals Material with high efficiency in wound healing (Wiegand et al, 2006) Promising material for wound healing therapy (Fu et al, 2014;Phisalaphong and Jatupaiboon, 2008) Composites with great antimicrobial activity ( grafting of methyl terminated octadecyltrichlorosilane (Taokaew et al, 2015) grafting of amine terminated 3-aminopropyltriethoxysilane (Taokaew et al, 2015) RGD peptides:  Attachment through cellulose binding modules )  Attachment through xyloglucan binding modules IKVAV peptide sequence:  Attachment through carbohydrate binding modules (Pertile et al, 2012) ɛ-Polylysine:  Penetration of a solution into the BC matrix followed by crosslinking with pr...…”

Biosynthesis of Polymers

“…The production of NFBC by ATCC23769 under rotating culture conditions suggested that the production of NFBC is not necessarily solely dependent on the type of strain. Taken together, these results led us to conclude that NEDO-01 is suitable for cellulose production from waste glycerol under rotating cultivation conditions [30].…”

“…Additionally, Cheng et al reported that a segmentalized BC (a BC pellet) was produced and BC production was enhanced by the addition of CMC to the culture medium, which prevented the aggregation of microfibrils [27]. On the basis of these findings, the rotating and agitating cultivation conditions of NEDO-01 were examined in a medium containing waste glycerol as a carbon source and CMC as an inhibitor of cellulose microfibril aggregation, in an attempt to achieve a one-step, large-scale production of NFBC from waste glycerol [30].…”
