The acid degumming waste of the seeds oil refining industry is currently disposed of, but, instead, it could be exploited as an important source for the preparation of many products. In this work, the waste coming from the soybean oil refining step was first recovered and treated, allowing the isolation of a fraction enriched of phospholipids (PLs). Then, the latter was transformed, via an enzymatic reaction catalysed by phospholipase D (from Streptomyces netropsis), into more valuable products: polar head modified PLs-enriched mixtures containing phosphatidylserine (PS), phosphatidylglycerol (PG), phosphatidylethanolamine (PE) and phosphatidylhydroxybutyrate (PB). In the following we show how biocatalysis can be exploited for the production of value-added PLs, to be used as functional food and nutraceutical ingredients, from a renewable feedstock. This alternative to the industrial usual disposal procedures should impart to the whole process a greater value in terms of carbon recycling, in agreement with the paradigms of bioeconomy for a wiser reuse of renewable resources in a circular economy perspective.

豆油酸脱胶废料的开发利用：高价值磷脂的生物催化合成

种子油精炼行业的酸脱胶废物目前已被处理，但可以作为制备许多产品的重要来源加以利用。在这项工作中，来自大豆油精炼步骤的废物首先被回收和处理，从而分离出富含磷脂 (PL) 的部分。然后，后者被转化，通过选自S由磷脂酶d（催化的酶促反应treptomyces netropsis)，转化为更有价值的产品：含有磷脂酰丝氨酸 (PS)、磷脂酰甘油 (PG)、磷脂酰乙醇胺 (PE) 和磷脂酰羟基丁酸酯 (PB) 的富含极性头修饰的 PLs 混合物。在下文中，我们将展示如何利用生物催化从可再生原料生产增值 PL，用作功能性食品和营养成分。这种替代工业通常处理程序的方法应该在碳循环方面赋予整个过程更大的价值，这与生物经济范式一致，以便在循环经济的角度更明智地再利用可再生资源。
