Abstract Specified risk materials (SRMs) are the tissues in cattle where misfolded proteins that cause "mad cow disease" are likely to concentrate, and thus they must be segregated from normal consumption. In this study, peptides derived from SRM hydrolysates were characterized and applied in the development of tackifiers. As one of the key components of a hydro-mulch mixture, tackifiers are employed to bind wood fibres and seeds of plants to the soil in order to facilitate improved rooting. However, sufficient hydrophobicity is also required by tackifiers to prevent diffusion and loss of function when exposed to high levels of moisture. Thus, glutaraldehyde cross-linking was examined to moderate hydrophobicity of SRM-derived peptides. Moreover, other characteristics of the peptides and cross-linked products were assessed and compared with commercial tackifiers. This demonstrated the competitiveness and potential of our SRM bioconversion strategy to produce tackifiers.

用于增粘剂应用的与戊二醛交联的热水解特定风险材料的评估

摘要 特定风险物质（Specified risk materials，SRMs）是牛的组织，在这些组织中，导致“疯牛病”的错误折叠蛋白质很可能集中，因此必须将它们与正常食用分开。在这项研究中，来自 SRM 水解产物的肽被表征并应用于增粘剂的开发。作为水覆盖混合物的关键成分之一，增粘剂用于将木纤维和植物种子粘合到土壤上，以促进生根。然而，增粘剂也需要足够的疏水性，以防止在暴露于高水分时的扩散和功能丧失。因此，检查戊二醛交联以调节 SRM 衍生肽的疏水性。而且，评估了肽和交联产品的其他特性，并与商业增粘剂进行了比较。这证明了我们的 SRM 生物转化策略在生产增粘剂方面的竞争力和潜力。
