“…Alternatively this could be obtained by chemical modification of BNC. Numerous chemical modifications of BNC have been reported in literature, aimed at promoting cell adhesion on BNC (Bodin et al, 2007a;Kalaskar et al, 2008), functionalizing it with drugs (Barud et al, 2008;Klechkovskaya et al, 2008;Nguyen et al, 2008) or tuning its biodegradability (Kusuhara et al, 2009) and producing nanocomposites (Grande et al, 2009;Wan et al, 2007). Interestingly Svensson et al (Svensson et al, 2005) demonstrated that chemical modifications such as sulfonation or phosphorylation could also increase BNC compressive modulus (i.e.…”

Finally, a biofabrication process to produce patient-specific BNC auricular implants is demonstrated.BNC samples (n = 78) with varying cellulose content (2.5 -15%) were compared using stressrelaxation indentation with human ear cartilage (n = 17, from 4 males, aged 49 -93 years old).Additionally, an auricle from a volunteer was scanned using a 3T MRI with a spoiled gradientecho sequence. A negative ear mold was produced from the MRI data in order to investigate if an ear-shaped BNC prototype could be produced from this mold.The results show that the instantaneous modulus E in , equilibrium modulus E eq , and maximum stress σ max of the BNC samples are correlated to effective cellulose content. Despite significantly different relaxation kinetics, the E in , E eq and σ max of BNC at 14% effective cellulose content reached values equivalent to ear cartilage (for E eq , BNC: 2.4 ± 0.4 MPa and ear cartilage: 3.3 ± 1.3 MPa). Additionally, this work shows that BNC can be fabricated into patient-specific auricular shapes. In conclusion, BNC has the capability to reach mechanical properties of relevance for ear cartilage replacement, and can be produced in patient-specific ear shapes.

“…Zhu et al (2010) evaluated a sausage casing made of BC embedded with Ɛ-polylysine, and they found that the casing exhibited bactericidal activities against several Gram-positive and Gram-negative bacteria, thus extending the shelf life of the product. Nguyen et al (2008) produced a BC film containing nisin to investigate its potential as an antimicrobial packaging device. It was tested against Listeria monocytogenes on the surface of vacuumpackaged sausages.…”

In recent decades, worldwide economic and environmental issues have prompted research scientists to re-direct their interests to bio-based resources, which are sustainable in nature. In this context, microbial polysaccharides, such as bacterial cellulose (BC), also known as microbial cellulose (MC), are some of the upcoming and emergent resources and have potential application in various bio- and non-bio-based sectors of the modern world. Many researchers have already established novel BC/MC production methods, and many new studies have been published on lab-scale and large-scale production aspects of BC/MC to date. To further expand the novel use of this sustainable source, significant progress toward the development of BC/MC has appeared in recent years. Specifically, there have been many publications and/or research reports on the valorization of BC/MC in the food, paper, materials, biomedical, pharmaceutical, and cosmeceutical industries, among others. This review will address the novel application aspects of BC/MC today, with the aim of demonstrating the importance of this sustainable and novel source in the development of value-added products.

Abstract.Bacterial cellulose (BC) shows good potentiality as active packaging material. However, bacterial cellulose itself has no antimicrobial activity to prevent microbial contamination. To achieve antimicrobial activity, ε-poly lysine (ε-PL) was incorporated into BC by immersing BC in ε-PL solution. Investigations into the effects of ε-PL concentrations and contact times on incorporation of ε-PL into cellulose membranes showed that the lowest ε-PL concentration and the shortest time for production of an effective antimicrobial cellulose membrane (ε-PL/BC) were 400 mg/l and 2 hours, respectively. The antimicrobial cellulose membrane was characterized by FTIR, XRD and AFM. It was found that ε-PL is incorporated into the BC network, and the antimicrobial cellulose membrane is not a simple mixture of BC and ε-PL. In this study ε-PL/BC membranes are demonstrated to have potential applicability as antimicrobial packaging films.
