Cellulose, the most abundant polymer on Earth, has been widely utilized in its nanoform due to its excellent properties, finding applications across various scientific fields. As the demand for nanocellulose continues to rise and its ease of use becomes apparent, there has been a significant increase in research publications centered on this biomaterial. Nanocellulose, in its different forms, has shown tremendous promise as a tissue engineered scaffold for regeneration and repair. Particularly, nanocellulose-based composites and scaffolds have emerged as highly demanding materials for both soft and hard tissue engineering. Medical practitioners have traditionally relied on collagen and its analogue, gelatin, for treating tissue damage. However, the limited mechanical strength of these biopolymers restricts their direct use in various applications. This issue can be overcome by making hybrids of these biopolymers with nanocellulose. This review presents a comprehensive analysis of the recent and most relevant publications focusing on hybrid composites of collagen and gelatin with a specific emphasis on their combination with nanocellulose. While bone and skin tissue engineering represents two areas where a majority of researchers are concentrating their efforts, this review highlights the use of nanocellulose-based hybrids in these contexts.

“…BC membranes have free hydroxyl groups on the surface; therefore, a given polymer can be easily modified with other polymers or additives to obtain the special properties of this metabolite (Sun et al 2019 ). An example of in situ modification is the study by Liyaskin et al ( 2018 ), who used the addition of alginate during the cultivation of bacteria of the species Komagataeibacter sucrofermentans B-11267. As a result of cultivation (5 days, 28 °C), they obtained a BC/alginate nanocomposite, which showed biotic activity against bacteria of the Staphylococcus aureus species.…”

Every year, all over the world, the industry generates huge amounts of residues. Side-streams are most often used as feed, landfilled, incinerated, or discharged into sewage. These disposal methods are far from perfect. Taking into account the composition of the side-streams, it seems that they should be used as raw materials for further processing, in accordance with the zero-waste policy and sustainable development. The article describes the latest achievements in biotechnology in the context of bacterial reprocessing of residues with the simultaneous acquisition of their metabolites. The article focuses on four metabolites — bacterial cellulose, propionic acid, vitamin B12 and PHAs. Taking into account global trends (e.g. food, packaging, medicine), it seems that in the near future there will be a sharp increase in demand for this type of compounds. In order for their production to be profitable and commercialised, cheap methods of its obtaining must be developed. The article, in addition to obtaining these bacterial metabolites from side-streams, also discusses e.g. factors affecting their production, metabolic pathways and potential and current applications. The presented chapters provide a complete overview of the current knowledge on above metabolites, which can be helpful for the academic and scientific communities and the several industries. Key points • The industry generates millions of tons of organic side-streams each year. • Generated residues burden the natural environment. • A good and cost-effective method of side-streams management seems to be biotechnology – reprocessing with the use of bacteria. • Biotechnological disposal of side-streams gives the opportunity to obtain valuable compounds in cheaper ways: BC, PA, vitmain B12, PHAs.

“…Pode-se citar outras propriedades da CB como a alta pureza, biocompatibilidade, não toxicidade, estabilidade mecânica, permeabilidade a líquidos e gases (PORTELA et al, 2019;SULAEVA et al, 2015). A CB se apresenta como um material promissor para aplicação como curativo no processo de cura de feridas, pois fornece um ambiente úmido acarretando em melhor cicatrização, mas não possui atividade antimicrobiana a fim de prevenir possível infecção (LIYASKINA et al, 2018;MANEERUNG;TOKURA;RUJIRAVANIT, 2008;BARUD et al, 2016).…”

Estratégias a fim de superar os pontos fracos dos biopolímeros e ampliar sua área de aplicação vêm sendo largamente estudadas, e uma das alternativas consiste em combina-los com outros materiais (plastificantes, outros polímeros e biopolímeros, extratos naturais, agentes antimicrobianos, grupos aminoalquil, agentes reticulante). Este estudo buscou investigar a melhor estratégia de incorporação da solução aquosa de schizophyllan (SPG) na membrana de celulose bacteriana (CB) com o objetivo de conferir ao produto final propriedades atraentes para aplicações na área médica. Para promover maior afinidade entre os biopolímeros, a membrana de CB foi modificada com um aminosilano. Metodologias diferentes foram testadas e a eficiência de incorporação do SPG em matriz de CB foi avaliada. Por espectroscopia na região do infravermelho (FTIR) foi possível identificar que a CB que foi funcionalizada apresentou bandas em torno de 1600 cm-1 atribuídas às deformações de grupos NH2. Entretanto, a análise de difratometria de Raios X (DRX) não revelou a presença do SPG, mas usando outra metodologia o SPG estava presente pelo surgimento de um novo pico em aproximadamente 28 ° (2θ). Existe um indicativo pelas imagens de microscopia eletrônica de varredura (MEV) da presença do SPG na matriz da celulose. Quanto a estabilidade térmica dos biocompósitos não ocorram mudanças significativas que comprometessem a sua aplicabilidade. Este estudo mostrou que as metodologias abordadas são complementares e devem ser fundidas para obtenção de melhores resultados e que uma das metodologias aplicadas aos biopolímeros sem modificação deve ser melhor investigada.
