Journal of Ocean University of China 2024年第5期23卷 1319-1328页

Chitin is the second most abundant renewable polysaccharide on Earth. The degradation of chitin into soluble and bioactive N-acetyl chitooligosaccharides(NCOSs) and N-acetyl-D-glucosamine(GlcNAc) has emerged as a pivotal step in the efficient and sustainable utilization of chitin resources. However, because of its dense structure, high crystallinity, and poor solubility, chitin typically needs pretreatment via chemical, physical, and other methods before enzymatic conversion to enhance the accessibility between substrates and enzyme molecules. Consequently, there has been considerable interest in exploring the direct biological degradation of crystalline chitin as a cost-effective and environment-friendly technology. This review endeavors to present several biological methods for the direct degradation of chitin. We primarily focused on the importance of chitinase containing chitin-binding domain(CBD). Additionally, various modification strategies for increasing the degradation efficiency of crystalline chitin were introduced. Subsequently, the review systematically elucidated critical components of multi-enzyme catalytic systems, highlighting their potential for chitin degradation. Furthermore, the application of microorganisms in the degradation of crystalline chitin was also discussed. The insights in this review contribute to the explorations and investigations of enzymatic and microbial approaches for the direct degradation of crystalline chitin, thereby fostering advancements in biomass conversion.

Prolonged Consumption of Dietary Advanced Lipoxidation End Products contributes to renal impairment in mice through Dysregulated Intestinal homeostasis

引用

food Science and Human Wellness 2024年

作者： Yaya Wang Lu Dong Yaozhong Hu Tianchang Zhang Ruican Wang Linqing Nie Junping Wang Yan Zhang Shuo Wang Tianjin key laboratory of food Science and Health， School of Medicine， Nankai University State key laboratory of food Nutrition and Safety， key laboratory of food Nutrition and Safety， College of food Engineering and biotechnology， Tianjin University of Science and Technology

Heat processing of food has been well validated as the trigger to generate heat-processing side product of advanced lipoxidation end products (ALEs)， which potentially engenders the threat on systemic health or progression of diseases， especially the accumulated effect after long-term intake. Thus， the study was proposed to evaluate the effect of dietary ALEs on health after long-term ingestion， specifically through simulating the intake of dietary ALE in mice within 9 months to investigate the intervention effect and underlying mechanism. The unexpected observation of renal insufficiency or impairment after long-term intake of dietary ALEs indicated the negative impact on renal health， which has been verified by the pathological analysis. Further studies revealed that a high-ALEs diet disrupted the intestinal barrier， with enhanced impact after disturbing the gut microbiota to potentially lower the abundance of beneficial microbiome through producing nephrotoxic metabolites. Correlation analysis showed that the proliferation of harmful bacteria and the reduction of beneficial bacteria were strongly correlated with intestinal barrier damage and the development of renal insufficiency. Furthermore， the underlying mechanism was unveiled as that ALEs could inhibit AMPK/SIRT1 signaling to fundamentally induce renal inflammation and oxidative stress. Thus， it was revealed that long-term intake of dietary ALE could result in renal impairment， and the results emphasized the control or intervention on dietary ALE to decrease to accumulated impairment on systemic health.
