Abstract

Polyphosphates, chains of polymerized phosphate subunits, are used as food additives for various applications such as conservation, water retention, and pH buffering. Currently, the value chain of phosphates is linear, based on mining fossil phosphate rock, which is anticipated to be depleted in a few hundred years. With no replacement available, a transition to a circular phosphate economy, to which biological systems can contribute, is required. Baker’s yeast can hyperaccumulate phosphate from various phosphate-rich waste streams and form polyphosphates, which can be used directly or as polyphosphate-rich yeast extract with enhanced properties in the food industry. By maturing the technology to an industrial level and allowing upcycled waste streams for food applications, substantial contributions to a sustainable phosphate economy can be achieved.

以生物技术聚磷酸盐为契机，促进磷酸盐经济的循环利用

聚磷酸盐是由聚合磷酸盐亚基组成的链，被用作食品添加剂，具有保存、保水和缓冲 pH 值等多种用途。目前，磷酸盐的价值链是线性的，以开采化石磷酸盐岩为基础，而化石磷酸盐岩预计将在几百年后枯竭。在没有替代品的情况下，需要过渡到循环磷酸盐经济，而生物系统可以为此做出贡献。贝克酵母能从各种富含磷酸盐的废物流中过度积累磷酸盐，并形成多磷酸盐，这些多磷酸盐可直接使用，或作为富含多磷酸盐的酵母提取物用于食品工业，并增强其特性。通过使该技术成熟到工业化水平，并允许食品应用中的废物流进行再循环，可以为可持续磷酸盐经济做出重大贡献。

期刊介绍： Current Opinion in Biotechnology (COBIOT) is renowned for publishing authoritative, comprehensive, and systematic reviews. By offering clear and readable syntheses of current advances in biotechnology, COBIOT assists specialists in staying updated on the latest developments in the field. Expert authors annotate the most noteworthy papers from the vast array of information available today, providing readers with valuable insights and saving them time. As part of the Current Opinion and Research (CO+RE) suite of journals, COBIOT is accompanied by the open-access primary research journal, Current Research in Biotechnology (CRBIOT). Leveraging the editorial excellence, high impact, and global reach of the Current Opinion legacy, CO+RE journals ensure they are widely read resources integral to scientists' workflows. COBIOT is organized into themed sections, each reviewed once a year. These themes cover various areas of biotechnology, including analytical biotechnology, plant biotechnology, food biotechnology, energy biotechnology, environmental biotechnology, systems biology, nanobiotechnology, tissue, cell, and pathway engineering, chemical biotechnology, and pharmaceutical biotechnology.
