用空气做成的食物价格可与大豆价格竞争

芬兰科学家称，在未来十年内，这种“用空气制成的”蛋白质将在价格上与大豆竞争。这种蛋白质是由土壤细菌制成的，这种细菌以电解水中的氢为食。

With farming blamed for contributing to many environmental problems, there's been increasing investment in novel foods grown from bacteria. A study last year concluded that protein from microbes was several times more efficient than soya in terms of land use and required just a tenth of the water.

由于务农活动被认为是造成许多环境问题的原因，人们对由细菌制成的新型食物的投资不断增加。去年的一项研究得出结论：制造微生物蛋白质的土地使用效率要比种植大豆高出数倍，而且用水量仅需其十分之一。

The bacteria food, Solein, can be used as a substitute for soya in a host of foods, such as pies, ice creams, breads and cakes. It can also feed livestock without harming rainforests in the way new soya plantations often do.

这个名为 “Solein” 的细菌食品可作为许多食物中大豆的替代品，如馅饼、冰淇淋、面包和蛋糕。它还可以在不破坏热带雨林的情况下用来喂养牲畜，在这一点上它与多数新型大豆种植园的做法相同。

Academics say it won't be a cure for all the problems associated with farming, but it will help if people are willing to eat it.

学者们表示，这不会完全解决与务农相关的所有问题，但如果人们愿意吃它，则将有一些帮助。
