Abstract
As one of the most abundant natural polysaccharides that possess good biological activity, chitosan is extracted from chitin. Its application in the food field is being increasingly valued. However, chitosan extraction is difficult, and its poor solubility limits its application. At present, the extraction methods include the acid-base method, new chemical methods, and biological methods. The extraction rates of chitin/chitosan are 4-55%, 13-14%, and 15-28%, respectively. Different chemical modifications have different effects on chitosan, making it applicable in different fields. This article reviews and compares the extraction and chemical modification methods of chitosan, emphasizing the importance of green extraction methods. Finally, the application prospects of chitosan in the food industry are discussed. This will promote the understanding of the advantages and disadvantages of different extraction methods for chitosan as well as the relationship between modification and application, providing valuable insights for the future development of chitosan.

Biotechnol J 2024; 19:e2300010. [PMID: 37705423 DOI: 10.1002/biot.202300010] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/05/2023] [Revised: 09/01/2023] [Accepted: 09/08/2023] [Indexed: 09/15/2023]
Abstract
Catalysis activity and thermostability are some of the fundamental characteristic of enzymes, which are of great significance to their industrial applications. Bacillus subtilis chitosanase BsCsn46A is a kind of enzyme with good catalytic activity and stability, which can hydrolyze chitosan to produce chitobiose and chitotriose. In order to further improve the catalytic activity and stability of BsCsn46A, saturation mutagenesis of the C-terminal K242 of BsCsn46A was performed. The results showed that the six mutants (K242A, K242D, K242E, K242F, K242P, and K242T) showed increased catalytic activity on chitosan. The catalytic activity of K242P increased from 12971 ± 597 U mg-1 of wild type to 17820 ± 344 U mg-1 , and the thermostability of K242P increased by 2.27%. In order to elucidate the reason for the change of enzymatic properties, hydrogen network, molecular docking, and molecular dynamics simulation were carried out. The hydrogen network results showed that all the mutants lose their interaction with Asp6 at 242 site, thereby increasing the flexibility of Glu19 at the junction sites of α1 and loop1. Molecular dynamics results showed that the RMSD of K242P was lower at both 313 and 323 K than that of other mutants, which supported that K242P had better thermostability. The catalytic activity of mutant K242P reached 17820.27 U mg-1 , the highest level reported so far, which could be a robust candidate for the industrial application of chitooligosaccharide (COS) production.

[PMID: 37099965 DOI: 10.1016/j.enzmictec.2023.110242] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2023] [Revised: 04/11/2023] [Accepted: 04/12/2023] [Indexed: 04/28/2023]
Abstract
Threonine 22 (Thr22) located in catalytic center near the catalytic amino acid Glu19 was non-conserved in Bacillus species chitosanase. In order to study the function of Thr22, saturation mutagenesis was carried out towards P121N, a mutant previously constructed in our laboratory. Compared with P121N, which was designated as the wild type (WT) in this research, the specific enzyme activity of all mutants was decreased, and that of the T22P mutant was decreased by 91.6 %. Among these mutants, the optimum temperature decreased from 55 °C to 50 °C for 10 mutants and 45 °C for 4 mutants, respectively. The optimum temperature of mutant T22P was 40 °C. In order to analyze the reasons for the changes in enzymatic properties of the mutants, molecular docking analysis of WT and its mutants with substrate were performed. The hydrogen bond analysis around position 22 also conducted. The substitution of Thr22 was found to significantly affect the enzyme-substrate complex interaction. In addition, the hydrogen network near position 22 has undergone obvious changes. These changes may be the main reasons for the changes in enzymatic properties of the mutants. Altogether, this study is valuable for the future research on Bacillus chitosanase.

Abstract
Chitosanase plays an important role in chitooligosaccharides (COS) production. We found that the chitosanase (BaCsn46A) of Bacillus amyloliquefacien was a good candidate for chitosan hydrolysis of COS. In order to further improve the enzyme properties of BaCsn46A, the S196 located near the active center was found to be a critical site impacts on enzyme properties by sequence alignment analysis. Herein, saturation mutation was carried out to study role of 196 site on BaCsn46A catalytic function. Compared with WT, the specific enzyme activity of S196A increased by 118.79%, and the thermostability of S196A was much higher than WT. In addition, we found that the enzyme activity of S196P was 2.41% of that of WT, indicating that the type of amino acid in 196 site could significant affect the catalytic activity and thermostability of BaCsn46A. After molecular docking analysis we found that the increase in hydrogen bonds and decrease in unfavorable bonds interacting with the substrate were the main reason for the change of enzyme properties which is valuable for future studies on Bacillus species chitosanase.

Abstract
Chitosanases are potential candidates for chitooligosaccharides (COS) production-based industries, therefore, the discovery of chitosanases having commercial potential will remain a priority worldwide. This study aims to characterize different chitosanases of Bacillus strains for COS production. Six different indigenous Bacillus strains (B. cereus EGE-B-6.1m, B. cereus EGE-B-2.5m, B. cereus EGE-B-5.5m, B. cereus EGE-B-10.4i, B. thuringiensis EGE-B-3.5m, and B. mojavensis EGE-B-5.2i) were used to purify and characterize chitosanases. All purified chitosanases have a similar molecular weight (37 kDa) as determined by sodium dodecyl sulfate-polyacrylamide gel electrophoresis. However, other characteristics such as optimum temperature and pH, kinetic parameters (Km and Vmax ), temperature, and pH stabilities were dissimilar among the strains of different Bacillus species and within the same species. Furthermore, chitosanases of all strains were able to successfully hydrolyze chitosan to COS and oligomers of the degree of polymerization 2-6 were detected with chitobiose and chitotriose as major hydrolysis products. The relative yields of COS were in a range of 19%-31% and chitosanase of B. thuringiensis EGE-B-3.5m turned out to be the best enzyme in terms of its characteristics and COS production potential with maximum relative yield (31%). Results revealed that Bacillus chitosanases could be used directly for efficient bioconversion of chitosan into COS and will be valuable for large-scale production of biologically active COS.

Abstract
Chitin extraction from shrimp shell powder (SSP) using protease-producing microbes is an attractive approach for valorizing shrimp shell waste because it is simple and environmentally friendly. In this study, the protease production and chitin extraction from SSP by Bacillus cereus HMRSC30 were simultaneously optimized using statistical approaches. As a result, fermentation in medium composed of 30 g/L SSP, 0.2 g/L MgSO4 · 7H2O, 3 g/L (NH4)2SO4, 0.5 g/L K2HPO4, and 1.5 g/L KH2PO4 (pH 6.5) for 7 days maximized protease production (197.75 ± 0.33 U/mL) to approximately 1.64-fold compared to unoptimized condition (126.8 ± 0.047 U/mL). This level of enzyme production was enough to achieve 97.42 ± 0.28% deproteinization (DP) but low demineralization (DM) of 53.76 ± 0.21%. The high DM of 90% could be easily accomplished with the post-treatment using 0.4 M HCl and acetic acid. In addition, the study evaluated the possible roadmap to maximize the value of generated products and obtain additional profits from this microbial process. The observation showed the possibility of serving crude chitin as a bio-adsorbent with the highest removal capacity against Coomassie brilliant blue (97.99%), followed by methylene blue (74.42%). The recovered protease exhibited the function to remove egg yolk stain, indicating its potential for use as a detergent in de-staining. The results corroborated the benefits of microbial fermentation by B. cereus HMRSC30 as green process for comprehensive utilization of shrimp shell waste as well as minimizing waste generation along the established process.
