摘要
聚β-羟基丁酸酯(PHB)是短链脂肪酸β-羟基丁酸的聚合体,广泛存在于微生物细胞中,是营养及能量储存物质,参与细胞代谢的天然产物。研究表明,饲料中添加PHB对水生动物生长性能、消化功能、抗氧化能力、免疫功能及肠道菌群等方面均有一定的影响。文章在查阅国内外相关文献报道的基础上,概述了PHB的生物学功能及其对水生动物健康的影响,可为新型免疫增强剂的开发及PHB在水生动物饲料中的广泛应用提供参考。
Poly-β-hydroxybutyrate(PHB)is a polymer of short-chain fatty acidβ-hydroxybutyrate,which is widely existing in microbial cells.It serves as a nutrient and energy storage substance and is a natural product involved in cellular metabolism.Studies showed that dietary PHB had certain effects on the growth performance,digestive function,antioxidant capacity,immune function and intestinal microbiota of aquatic animals.Based on the relevant literature reports,this paper summarized the biological function of PHB and its effects on the health of aquatic animals,and provided a reference for the development of a new type of immunostimulant and the extensive application of PHB in aquatic animal feed.
