“…It is different from before where ultrasonication was used to assist the CNCs production. Here, ultrasonication is used for a produced CNCs suspension to prevent the CNCs agglomeration [58]. Moreover, several studies reported that the size of CNCs changed before and after the ultrasonication process, where it significantly reduced the size of CNCs as shown in Table 4 [43,58].…”

Due to their biocompatibility, biodegradability, and non-toxicity, lignocellulosic-derived nanoparticles are very potential materials for drug carriers in drug delivery applications. There are three main lignocellulosic-derived nanoparticles discussed in this review. First, lignin nanoparticles (LNPs) are an amphiphilic nanoparticle which has versatile interactions toward hydrophilic or hydrophobic drugs. The synthesis methods of LNPs play an important role in this amphiphilic characteristic. Second, xylan nanoparticles (XNPs) are a hemicellulose-derived nanoparticle, where additional pretreatment is needed to obtain a high purity xylan before the synthesis of XNPs. This process is quite long and challenging, but XNPs have a lot of potential as a drug carrier due to their stronger interactions with various drugs. Third, cellulose nanocrystals (CNCs) are a widely exploited nanoparticle, especially in drug delivery applications. CNCs have low cytotoxicity, therefore they are suitable for use as a drug carrier. The research possibilities for these three nanoparticles are still wide and there is potential in drug delivery applications, especially for enhancing their characteristics with further surface modifications adjusted to the drugs.

“…Thus, the açaí seed shows itself as an interesting alternative source of cellulose, since the amount of cellulose that constitutes this residue is higher than that observed in other important agro-industrial residues, i.e., sugarcane bagasse, coffee hull, peanuts husks, among others (Table 2). The contents of cellulose and hemicellulose are also important in agro-industrial residues, given the possibility of obtaining compounds with high added value: sugars through their hydrolysis of these polymers (Akhlisah, Yunus, Abidin, Lim, & Kania, 2021;Javed, Ansari, Aman, & Ul Qader, 2019;Pereira & Arantes, 2020), bioethanol (Malik et al, 2021;Zoubiri, Rihani, & Bentahar, 2020) and other derivatives such as 5-hydroxymethylfurfural and levulinic acid (Freitas et al, 2016;Malik et al, 2021;Melro et al, 2020).…”

O açaí (Euterpe precatoria Mart.) é uma planta amplamente cultivada na região norte do Brasil. Seus frutos vêm ganhando destaque mundial devido aos inúmeros benefícios para a saúde humana. Consequentemente, a produção de celulose aumentou consideravelmente nos últimos anos, gerando uma quantidade significativa de resíduos (principalmente sementes). Como esses resíduos não têm uma destinação adequada, eles são descartados no meio ambiente ou incinerados, causando inúmeros impactos ambientais. Com o objetivo de apresentar alternativas de aplicação desses resíduos, este trabalho teve como objetivo avaliar o conteúdo lignocelulósico das sementes de açaí - extratos, cinzas, lignina, celulose (α-celulose e hemicelulose) - além de extrair e caracterizar a celulose obtida desse abundante resíduo. As sementes e a celulose extraída foram caracterizadas por diversas técnicas: fluorescência de raios X (XRF), difração de raios X (XRD), refletância total atenuada com espectroscopia de infravermelho por transformada de Fourier (ATR / FTIR) e termogravimetria (TGA). Neste estudo, foi confirmado o alto potencial do uso da semente de açaí como fonte alternativa de celulose, uma vez que apresenta 45,5% desse polímero e todas as técnicas de caracterização mostram a pureza da celulose extraída (tipo I).

“…The minimization of residues by using environmentally friendly processes to produce renewable materials such as NC is in line with Agenda 2030 to achieve sustainable development. Moreover, this approach can provide economic benefits, increasing the industrial value chain [ 23 ]. Therefore, the evaluation of byproducts and wastes as a source of cellulose is also considered by industries and the scientific community [ 24 ].…”

Nanocellulose Production: Exploring the Enzymatic Route and Residues of Pulp and Paper Industry

Increasing environmental and sustainability concerns, caused by current population growth, has promoted a raising utilization of renewable bio-resources for the production of materials and energy. Recently, nanocellulose (NC) has been receiving great attention due to its many attractive features such as non-toxic nature, biocompatibility, and biodegradability, associated with its mechanical properties and those related to its nanoscale, emerging as a promising material in many sectors, namely packaging, regenerative medicine, and electronics, among others. Nanofibers and nanocrystals, derived from cellulose sources, have been mainly produced by mechanical and chemical treatments; however, the use of cellulases to obtain NC attracted much attention due to their environmentally friendly character. This review presents an overview of general concepts in NC production. Especial emphasis is given to enzymatic hydrolysis processes using cellulases and the utilization of pulp and paper industry residues. Integrated process for the production of NC and other high-value products through enzymatic hydrolysis is also approached. Major challenges found in this context are discussed along with its properties, potential application, and future perspectives of the use of enzymatic hydrolysis as a pretreatment in the scale-up of NC production.
