Detailed explanation of nanocellulose fermentation and cultivation process: Create a new path to high-purity bacterial cellulose With the continuous development of green and sustainable materials, nanocellulose (Nanocellulose) has shown great potential in many fields such as medical use, packaging, food, and electronic materials. Among them, Bacterial Cellulose (BC) prepared by microbial fermentation has become an important member of the nanocellulose family due to its high purity, uniform structure and three-dimensional network stability. This article will focus on the fermentation and culture process flow and key control parameters of bacterial cellulose, providing technical reference for efficient production. 1. Overview of the principle of fermentation culture nanocellulose is prepared by fermentation method. It is fermented in liquid culture medium containing carbon and nitrogen sources by fermentation of glucose and other substrates into β-1.

Application of nanocellulose in water treatment and adsorbents: Green and efficient emerging adsorbents With the acceleration of industrialization, the problem of water resource pollution is becoming increasingly serious. Traditional water treatment materials face challenges such as poor sustainability, low selectivity and high treatment costs. In recent years, Nanocellulose (Nanocellulose) has become an important candidate for the new generation of water treatment adsorbent materials due to its renewability, rich surface functional groups, high specific surface area and good mechanical properties. 1. The structure and adsorption potential of nanocellulose Nanocellulose is a material obtained by mechanical, chemical or biological nano-nanoization of natural cellulose. It mainly includes three forms: cellulose nanofiber (CNF), cellulose nanocrystal (CNC), bacterial cellulose (BC), which contains a large amount of hydroxyl groups on the surface, which can further introduce functional groups such as carboxyl groups, sulfonic acid groups, amino groups, and quaternary ammonium salt groups to enhance the use of different pollutants (such as heavy metal ions, organics).

Among the various preparation methods of nanocellulose, the fermentation method has attracted widespread attention due to its advantages such as green and environmental protection, high purity, and controllable structure. Nanocellulose synthesized by specific bacterial species under suitable conditions is called Bacterial Cellulose (BC). It is a natural polymer material derived from microbial fermentation. It has high crystallinity, excellent biocompatibility and a unique three-dimensional nanonetwork structure. 1. Principle of fermentation method. The fermentation method mainly uses **aceticobacter (such as Komagataeibacter xylinus) to synthesize cellulose nanochains by metabolism in culture medium rich in carbon and nitrogen sources. Under static culture conditions, bacteria form a gel-like film on the liquid surface, gradually accumulating film-forming bacterial cellulose. The formation process includes: glucose and other carbon sources are finely employed

Detailed explanation of the acid hydrolysis preparation process of nanocellulose Nanocellulose is a high-performance material obtained by nano-native treatment of natural cellulose, with excellent mechanical properties, thermal stability, biocompatibility and environmental friendliness. Among them, Acid Hydrolysis is a common and mature preparation method, which is particularly suitable for obtaining cellulose nanocrystals (CNCs). This process selectively degrades the amorphous region of cellulose through acidic media, thereby retaining the crystalline region and ultimately forming a highly ordered nanostructure. 1. Process principle The acid hydrolysis method mainly relies on strong acids such as concentrated sulfuric acid or hydrochloric acid to hydrolyze cellulose at an appropriate temperature and reaction time. The acid preferentially acts on the amorphous region of the cellulose, causing it to break and dissolve, while the crystalline region is relatively stable due to its dense molecular arrangement structure, thus retaining it to form nanocrystals. The final nanocellulose

Against the backdrop of global advocacy of sustainable development, biodegradable materials are becoming an important direction for materials scientific research and industrial applications. Bacterial Cellulose (BC), a natural nanocellulose synthesized by microorganisms, has shown strong development potential in many high-value-added industries due to its unique physical properties and biocompatibility. What is bacterial cellulose? Bacterial cellulose refers to the high-purity nano-scale fiber network structure produced by certain acetic acid bacteria (such as Komagataeibacter xylinus) in a suitable culture environment, and the structure of high purity and hemicellulose is different from that of plant-derived cellulose. Bacterial cellulose naturally does not contain impurities such as lignin and hemicellulose, and has extremely high purity and crystallinity. The production process is usually carried out through a liquid fermentation system, does not rely on crop resources, and has a lower environmental load.

The core advantages of nanocellulose: good biocompatibility, opening up new prospects for green applications. With the rise of research booms in renewable resources and green materials, nanocellulose (Nanocellulose), as a natural source bio-based nanomaterial, has attracted high attention from scientific and industrial circles for its good biocompatibility. It refers to the fact that when the material comes into contact with organisms, it will not cause an immune rejection toxic reaction or inflammatory reaction. It is a key indicator for evaluating whether the material is suitable for the biomedical field. Among all nanomaterials, nanocellulose is considered to be one of the best biocompatible materials at present due to its stable, non-toxic and harmless nature of natural source structure. It has brought a safe, environmentally friendly and functional solution to many fields such as pharmaceutical tissue engineering cosmetics and food. Why does nanocellulose have good biocompatibility? Natural plant source, green renewable nanocellulose extraction

The core advantages of nanocellulose: The multiple value brought by large specific surface area Nanocellulose is a green nanomaterial derived from natural plant fibers. In recent years, it has attracted much attention due to its environmental protection, high strength and renewability advantages. Among the many performance advantages, 'large specific surface area' is recognized as one of the most representative characteristics of nanocellulose. It is this structural feature that makes it show unique application potential in multiple fields such as composite materials biomedical environmental governance. What is specific surface area? Why is it important? Specific surface area refers to the total surface area of ​​a unit mass material. Usually, the larger the specific surface area of ​​a material is measured in square meters per gram (m²/g), the more active sites it has exposed on its surface, and can participate in more physical adsorption or chemical reactions, thereby directly affecting its performance. For nanocellulose, its fiber diameter is usually between 5 and 20 nanometers, and its length can reach several degrees.

Nanocellulose is a nano-scale material extracted from natural cellulose. It has high specific surface area, excellent mechanical properties and biodegradability, and its surface groups play an important role in the properties and applications of nanocellulose. By modifying and modifying its surface groups, the application performance of nanocellulose in various fields can be significantly improved. This paper will focus on the types and functions of nanocellulose surface groups and their modification methods. The functional groups on the surface of nanocellulose are mainly derived from the hydroxyl groups (-OH) in cellulose molecules and other groups introduced through hydrolytic oxidation or other chemical modification. Common surface groups include: 1. Hydroxyl groups (-OH) The surface of nanocellulose mainly contains a large amount of hydroxyl groups (-OH), which is the natural functional group of cellulose molecules.
