“…As is the usual case, the most common method of loading drugs in BC membranes is via immersion in the drug solution usually following lyophilisation to allow for maximum absorption of the drug [46]. The most common drugs to be incorporated into bacterial cellulose are anti-inflammatory drugs, such as ibuprofen and diclofenac, and antimicrobial drugs [47][48][49][50][51][52]. The efficiency of bacterial cellulose as a drug delivery material can be improved to provide additional properties and functions by exploiting tensile strength and water uptake to load the cellulose with antimicrobial compounds such as antibiotics [53,54].…”

Bacterial cellulose (BC) is an extracellular polymer produced by Komagateibacter xylinus, which has been shown to possess a multitude of properties, which makes it innately useful as a next-generation biopolymer. The structure of BC is comprised of glucose monomer units polymerised by cellulose synthase in β-1-4 glucan chains which form uniaxially orientated BC fibril bundles which measure 3–8 nm in diameter. BC is chemically identical to vegetal cellulose. However, when BC is compared with other natural or synthetic analogues, it shows a much higher performance in biomedical applications, potable treatment, nano-filters and functional applications. The main reason for this superiority is due to the high level of chemical purity, nano-fibrillar matrix and crystallinity. Upon using BC as a carrier or scaffold with other materials, unique and novel characteristics can be observed, which are all relatable to the features of BC. These properties, which include high tensile strength, high water holding capabilities and microfibrillar matrices, coupled with the overall physicochemical assets of bacterial cellulose makes it an ideal candidate for further scientific research into biopolymer development. This review thoroughly explores several areas in which BC is being investigated, ranging from biomedical applications to electronic applications, with a focus on the use as a next-generation wound dressing. The purpose of this review is to consolidate and discuss the most recent advancements in the applications of bacterial cellulose, primarily in biomedicine, but also in biotechnology.

“…They are ideal for constructing effective drug carriers, gene transfer devices and imaging biological systems. 55 The amine-terminated inside PAMAM dendrimers and the amino groups in chitosan are not protonated at physiological pH (7) while all first amines (dendrimer and chitosan) eventually protonated with a further decrease in pH (5.5-6). 47,56,57 Pressure and the electrostatic repulsion between the protonated amino groups can release drugs easily, if the pH was under 5, BC with dendrimer and chitosan was eroded.…”

“…To modify BC, various ways have been proposed to optimize its antimicrobial activity and biocompatibility. 7,8 The application of biopolymers such as bacterial polymers like chitosan, dendrimer and bacterial cellulose is one of the emerging adsorption methods for the removal of dyes, heavy metals and drug delivery. The presence of many amine groups on the chitosan and dendrimer chain, increase the adsorption capacity of dendrimer and chitosan.…”

This study mainly aimed to evaluate the antibacterial impact of bacterial cellulose (BC) including dendrimer, chitosan, Henna, Green tea and Malva sylvestris in various bacteria such as Staphylococcus aureus and Pseudomonas aeruginosa. The produced bacterial cellulose was evaluated by antimicrobial (AATCC 25923 and AATCC 27853), cytotoxicity, swelling, drug delivery, scanning electron microscopy (SEM) and Fourier Transform Infrared (FTIR) spectroscopy tests. Antibacterial activity raised with increasing concentration of herbals and the most of antimicrobial effect belonged to G. tea. Cytotoxic test demonstrated that all of the samples did not have cytotoxic effect and viability percent for sample of BC with Henna, G. tea, and M. sylvestris extract were respectively 95.87%, 94.69% and 90.64%. Among the samples, the G. tea sample has the most swelling. In addition, delivery of the drug in water and phosphate buffer medium was the controlled release. Additionally, the most of the release related to the herbal drug Henna. SEM results showed BC with a highly porous three dimensional network structure. The considerable role of chitosan and dendrimer was evident in drug uptake and release. FTIR analysis demonstrated the presence of active groups in BC structure.

“…Essa substituição dá-se em virtude da CB ter estrutura semelhante à da celulose vegetal e apresentar vantagens como fibras de caráter nanométrico, alta biodegradabilidade, baixos custo e impacto ambiental (Neves et al, 2018). Nessa perspectiva, estudos recentes já demonstraram a capacidade de utilização da celulose obtida através do SCOBY em filmes com atividade antimicrobiana (Battikh et al, 2013), curativos medicamentosos (El-Wakil et al, 2019), membranas de filtração (Eggensperger et al, 2020) e na indústria têxtil (Santos, 2020).…”

A kombucha é uma bebida milenar com alegação de propriedades funcionais que vem se popularizando no Brasil, resultado da fermentação de chá verde e/ou preto por uma associação simbiótica de bactérias e leveduras, SCOBY (Symbiotic Culture Of Bacteria and Yeast). Tem como objetivo realizar uma revisão integrativa da literatura para descrever os principais atributos biológicos da Kombucha, a fim de demostrar os benefícios à saúde, na perspectiva atual do mercado e seu potencial biotecnológico. A kombucha,é uma bebida fermentada à base de chá e de origem asiática, produzida por uma técnica de fermentação de chá preto ou verde adoçado, promovida por uma cultura de leveduras e bactérias. A composição química é variável tanto quantitativa quanto qualitativamente, pois depende da fermentação e substratos utilizados no chá inicial, estando relacionada aos ingredientes utilizados em sua fabricação e aos processos aplicados. Seu consumo frequente apresenta benefícios relacionados à sua atividade antioxidante com potencial habilidade de eliminação de radicais livres, e com isso atraindo o interesse do mercado global, em 2019, a indústria de kombucha valia US$ 1,67 bilhão e deve crescer cada vez mais. Portanto, a utilização do SCOBY como forma de obtenção de celulose bacteriana torna-se uma alternativa com potencial de rentabilidade, na caracterização da composição centesimal do SCOBY, encontra-se teores de proteínas e fibras alimentares em sua composição centesimal, de forma a constituir uma fonte alternativa na alimentação humana.
