“…Chemical acid hydrolysis and microbial conversion are two of the most often employed saponin conversion techniques [10]. Te advantage of the acid hydrolysis method is that the reaction conditions are simple, the ginsenosides are unstable in low pH acidic environments, and the acid will hydrolyze the connected sugar groups [11]. However, there is also the dehydration and cyclization of the saponin itself under acidic conditions or the change of the conformation of the saponin, which will eventually lead to more by-products in the fnal product, thereby increasing the separation cost, and only saponin monomers can be obtained, which is unsuitable for researching saponin conversion in the food feld [12].…”

The primary active components of plant ginseng are saponins, and rare saponins play a specific antitumor action. In this study, Lactobacillus that can efficiently transform rare saponins were screened as fermentation strains of ginseng enzymes. The fermentation process was optimized to investigate the changes in various biochemical indicators and antioxidant activities of the enzymes before and after fermentation. The results showed that Lactiplantibacillus plantarum had the highest conversion efficiency for diol saponins, among which the content of rare ginsenoside-CK increased by 256%. The optimum optimizing method was a 1 : 1 : 10 ratio of ginseng extract/concentrated apple juice/water, fermentation time of 16 days, initial pH of 6.0, fermentation temperature of 37°C, and sterilization amount of 1.0%. The contents of rare ginsenoside-Rh1, ginsenoside-F2, ginsenoside-Rg3, and ginsenoside-CK increased by 18.48%, 135.73%, 343.03%, and 441.80%, respectively, and the process was stable and controllable. After fermentation, the scavenging rates for hydroxyl radical, DPPH radical, and superoxide anion radical were increased by more than 9%, and new organic acids were produced. In general, this study established an efficient, stable, and controllable ginseng fermentation process to improve the rare saponin content and biological activity of ginseng enzymes, which can provide new ideas for traditional Chinese medicine and medicinal health food in China.

“…Zhang et al [ 22 ] found that acid treatment causes the hydrogen ions enter into the amorphous area of cellulose and destroy the amorphous area which result in the cellulose I C increment in agreement with Bodin et al [ 53 ]. The I C of the cellulose isolated from oil palm ( Elaeis guineensis ) empty fruit bunch (OPEFB)was 73.20% [ 28 ], while their values for pineapple leaves [ 54 ], indus-trial kelp ( Laminaria japonica ) [ 55 ], soy hulls [ 56 ], sisal, curaua, bamboo, and eucalyptus [ 57 ] and sugar palm ( Arenga Pinnata ) [ 58 ] were 54.00%, 69.40%, 73.50%, 78.00%, 87.00%, 87.00%, 89.00% and 85.90% respectively.…”

Recently, environmental and ecological concerns have become a major issue owing to the shortage of resources, high cost, and so forth. In my research, I present an innovative, environmentally friendly, and economical way to prepare nanocellulose from grass wastes with a sodium hypochlorite (NaClO) solution of different concentrations (1–6% mol) at different times 10–80 min, washed with distilled water, and treated with ultrasonic waves. The optimum yield of the isolated cellulose was 95%, 90%, and 87% NaClO at 25 °C for 20 min and with NaOH and H2SO4 at 25 °C with 5% M, respectively. The obtained samples were characterized by dynamic light scattering (DLS), Fourier-transform infrared (FT-IR) spectroscopy, and X-ray diffraction (XRD). The effect of test temperature and reaction times on the crystallinity index (IC) of GNFC with different treated mediums was carried out and investigated. The IC was analyzed using the diffraction pattern and computed according to the Segal empirical method (method A), and the sum of the area under the crystalline adjusted peaks (method B) and their values proved that the effect of temperature is prominent. In both methods, GNFC/H2SO4 had the highest value followed by GNFC/NaOH, GNFC/NaClO and real sample nano fiber cellulose (RSNFC). The infrared spectral features showed no distinct changes of the four cellulose specimens at different conditions. The particle size distribution data proved that low acid concentration hydrolysis was not sufficient to obtain nano-sized cellulose particles. The Zeta potential was higher in accordance with (GNFC/H2SO4 > GNFC/NaOH > GNFC/NaClO), indicating the acid higher effect.

“…Furthermore, the initial decomposition temperature of the nanocellulose obtained by enzymatic hydrolysis was higher than the temperatures of 228.2 and 130.0 °C reported by Yu et al and Tian et al, respectively, for nanocellulose prepared by the sulfuric acid method. Lower thermal stability can result from the introduction of sulfated species on the nanocellulose fibers during the H 2 SO 4 hydrolysis due to the substitution of hydroxyl groups (O–H) by sulfate (O–SO 3 H) …”

“…Xu and Chen 53 investigated the optimal conditions for the preparation of CNCs with high purity and found that the nanoparticles started to degrade at 260 °C, which was slightly lower than the temperature found in the present work. Furthermore, the initial decomposition temperature of the nanocellulose 56 The maximum degradation temperature, T max , is the temperature at which the thermal degradation rate is fastest, corresponding to the peak value of the derivative weight curve. As shown in Table 3, T max for the CNCs obtained from run 6 (347.4 °C) was slightly higher than the values for the ballmilled pulp (333.3 °C) and the control sample (333.6 °C), which also indicated a positive effect in terms of the thermal stability of the CNCs.…”

The development of process engineering approaches to integrate the production of biofuels and high value-added biobased products, such as enzymes and nanocellulose, is crucial to improve the financial performance and sustainability of lignocellulosic biomass biorefineries. Here, the feasibility of applying enzymes produced on-site to obtain nanocellulose was evaluated using eucalyptus cellulose pulp as a model feedstock. A systematic analysis of the structural properties of the nanomaterials obtained after hydrolysis using a cellulolytic enzymatic complex with high endoglucanase specific activity (17.09 IU/mg protein ), produced by Aspergillus niger, followed by sonication, revealed that longer ball milling pretreatment and reaction times favored extraction of the cellulose nanocrystals (CNCs). The highest yield (24.6%) of CNCs was achieved using 96 h of enzymatic hydrolysis of the ball-milled cellulose pulp, followed by sonication for 5 min. The CNCs presented approximate lengths of 294.0 nm and diameters of 24.0 nm, and the crystallinity index increased from 57.5% to 78.3%, compared to the cellulose pulp that was only ball milled. These findings demonstrated that nanocelluloses could be successfully extracted using on-site produced enzymes and that the sustainable integrated process reported here could contribute to the development of the nascent biobased economy.
