条斑甲藻（Pyropia yezoensisis）已被证明是生产高品质琼脂的新资源。然而，discoloredP.虽然也有一定的利用价值，但大部分被当作工业废料丢弃。在这里，我们评估了discoloredP的效用。yezoensisas是琼脂生产的资源。从变色的海藻中提取的琼脂质量与从正常海藻中提取的琼脂相当。此外，作为一个显着的特点，琼脂产量是从变色海藻高于正常类型。此外，我们成功地使用了从discoloredP。细菌平板培养基和不经琼脂糖纯化的DNA电泳凝胶。因此，我们的结果表明，变色P。适用于琼脂生产和在生命科学研究中的应用。转向变色P. yezoensis从处理到琼脂生产提供了一个解决目前海产养殖中工业废物问题的办法，也为研究目的提供了一个可靠的琼脂来源。
The red seaweedPyropia yezoensishas been demonstrated to be a novel resource for the production of high-quality agar.P. yezoensisis grown for the food industry in large-scale Japanese mariculture operations. However, discoloredP. yezoensisis mostly discarded as an industrial waste, although it has some kind of utility values. Here, we evaluated the utility of discoloredP. yezoensisas a resource for agar production. The quality of agar from the discolored seaweed was comparable to that from normal seaweed. In addition, as a distinguishing characteristic, agar yield was higher from discolored seaweeds than from normal types. Moreover, we successfully used agar from discoloredP. yezoensisfor bacterial plate media and DNA electrophoresis gels without agarose purification. Thus, our results demonstrate that discoloredP. yezoensisis suitable for agar production and use in life science research. Diverting discoloredP. yezoensisfrom disposal to agar production provides a solution to the current industrial waste problem in mariculture, as well as a secure source of agar for research purposes.
