Abstract
Polybion creates this next-generation material by feeding a mango fruit waste slurry to Acetobacter bacteria genetically modified to speed up their metabolism. The bacteria feed on the sugar and turn it into cellulose to form a gel-like mat on the surface of the fermentation tank. Bacteria employ this strategy to survive in harsh environments. “It’s a shelter they create [against] the radiation of the sun or to inhibit the growth of other competitors,” says José Manuel Aguilar-Yáñez, CSO of Polybion.
Once the skin-like layer, or pellicle, grows to the required thickness, Polybion scoops up the creamy-colored biofabric and washes it to kill the bacteria, then dries it in their solar-powered factory for up to 24 hours, after which the material undergoes tanning and dyeing in a process similar to that used for leather. Since its creation in 2020, the Polybion team has created one million square feet of Celium.
Polybion通过将芒果果渣浆喂给经过基因改造的醋酸杆菌来加速它们的新陈代谢，从而制造出这种新一代材料。细菌以糖为食，将其转化为纤维素，在发酵罐表面形成凝胶状垫。细菌利用这种策略在恶劣的环境中生存。Polybion的首席生态官jossure Manuel Aguilar-Yáñez说：“这是他们为阻挡太阳辐射或抑制其他竞争对手生长而建造的避难所。”一旦这种类似皮肤的生物纤维层达到所需的厚度，Polybion就会把这种奶油色的生物纤维捞起来，清洗以杀死细菌，然后在他们的太阳能工厂里干燥24小时，之后，这种材料会经历鞣制和染色的过程，类似于皮革的加工过程。自2020年成立以来，Polybion团队已经创造了100万平方英尺的Celium。
