This paper reviews the works on the characterization of the physical and chemical properties of Camellia nut shells, active ingredient extraction, its application in chemical production, growing media and animal feed and its properties as a biomass. Based on the review, we proposed a novel all-component high value application strategy to covert camellia nut shells into high value biomasses, which could realize waste recycling and environmental protection.展开更多
为探究脯氨酰内肽酶(prolyl endopeptidase,PEP)在骨胶原蛋白肽酶法制备过程中的应用潜力,分别以牛骨胶原蛋白(bovine bone collagen,BBC)、猪骨胶原蛋白(porcine bone collagen,PBC)、鸡骨胶原蛋白(chicken bone collagen,CBC)为原料,...为探究脯氨酰内肽酶(prolyl endopeptidase,PEP)在骨胶原蛋白肽酶法制备过程中的应用潜力,分别以牛骨胶原蛋白(bovine bone collagen,BBC)、猪骨胶原蛋白(porcine bone collagen,PBC)、鸡骨胶原蛋白(chicken bone collagen,CBC)为原料,对比分析3种不同来源骨胶原蛋白的序列特征,预测不同骨胶原蛋白潜在的酶解作用位点和理论水解度。在55℃、pH 8.0条件下,利用PEP水解处理3种不同来源骨胶原蛋白,通过水解度、分子质量分布测定和扫描电子显微镜观察等方法进行表征。利用红外光谱、X射线衍射和圆二色光谱等方法探究酶解过程中胶原蛋白结构变化。结果表明,PEP对3种不同来源骨胶原蛋白均有显著水解效果,PBC的水解度最高,为51.35%,其次分别为CBC(29.81%)和BBC(22.81%)。3种骨胶原蛋白酶解产物分子质量多分布在500 Da以下。光谱学分析表明PEP破坏了胶原蛋白的三螺旋结构,从而使胶原蛋白降解,达到制备胶原蛋白肽的效果。PEP可以高效酶解骨胶原蛋白制备小分子蛋白肽,本研究可为功能性骨胶原蛋白肽的酶法制备提供依据。展开更多
