Article Abstract

Recent studies have highlighted the prebiotic potential of natural plant polysaccharides, demonstrating their role in promoting beneficial gut microbiota and improving health. However, research on the digestive properties and prebiotic activities of (IRPs) remains limited. This study investigated fresh as the research object. After processing, dry and carbonized were prepared. Three polysaccharides from the fresh, dry, and carbonized were extracted with traditional hot water. And another polysaccharide was obtained by cold water extraction from fresh . Total four IRPs were extracted and named: IRPs-F, IRPs-D, IRPs-C, and IRPs-J. This study evaluated the prebiotic activity of four polysaccharides derived from the roots of thatch, demonstrating their resistance to digestion, their ability to promote probiotic growth, and their enhancement of short-chain fatty acid (SCFA) production. The final results show that four IRPs exhibit strong resistance to digestion and IRPs-F ability to promote the growth of beneficial probiotics, making it a promising candidate for functional foods aimed at improving intestinal health, immune regulation, and metabolic benefits. This research is highly relevant to food microbiology and holds significant potential for application in the functional food and gut health sectors.

Introduction: Straw return combined with rational nitrogen (N) fertilization plays a critical role in coordinating the transformation of soil organic carbon and nitrogen availability, thereby improving nitrogen use efficiency (NUE), crop yield, and soil fertility. However, the dynamics of soil carbon and nitrogen fractions under straw return with varying N inputs, and their specific contributions to NUE and yield, remain unclear.

Methods: A three-year split-plot field experiment was conducted in the Tumochuan Plain Irrigation District.

Chemical absorption of carbon dioxide using monoethanolamine (MEA) is a well-established method for postcombustion CO capture. In this study, we aimed to integrate (1) the MEA-based CO capture with the regeneration of MEA using calcium-based mineralization, followed by (2) direct utilization of captured CO to form syngas via a calcium looping-based dry reforming of methane (CaL-DRM), an interfacial catalytic process. The results show that room-temperature CO capture-MEA regeneration was achievable by using calcium-based mineralization.

Per- and polyfluoroalkyl substances (PFASs) have gained attention due to their chemical stability, bioaccumulation potential, and toxicity. The ocean serves as the ultimate sink for these compounds in the global environment. With the rapid development of the Hainan Free Trade Port, environmental pollution on Hainan Island has consequently become more pronounced.

Dry matter intake () estimation in ruminants is important for providing a balanced diet, increasing animal performance, and reducing nutrient excretion. Gas flux ( and production) is related to DMI; however, there is limited information regarding the use of gas flux production when estimating DMI in growing steers. This study aimed to 1) determine the relationship of animal growth performance and gas flux variables with DMI of growing steers fed a backgrounding diet, and 2) evaluate the DMI accuracy of eight equations to predict DMI from growing steers fed a forage-based diet.

Forest landscapes play a significant role in both global and local carbon cycles, mitigating climate change by sequestering atmospheric carbon. To maintain carbon stock and enhance sequestration from the atmosphere, it is important to quantify the effects of driving factors on carbon stock. Therefore, this study was designed to evaluate the effects of storing factors, maintaining factors, and disturbing factors on carbon stock, and to analyze the individual and combined effects of multiple factors.
