芬蘭科學家稱，在未來十年內，這種「用空氣製成的」蛋白質將在價格上與大豆競爭。這種蛋白質是由土壤細菌製成的，這種細菌以電解水中的氫為食。
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.
由於務農活動被認為是造成許多環境問題的原因，人們對由細菌製成的新型食物的投資不斷增加。去年的一項研究得出結論：製造微生物蛋白質的土地使用效率要比種植大豆高出數倍，而且用水量僅需其十分之一。
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.
這個名為 「Solein」 的細菌食品可作為許多食物中大豆的替代品，如餡餅、冰淇淋、麵包和蛋糕。它還可以在不破壞熱帶雨林的情況下用來餵養牲畜，在這一點上它與多數新型大豆種植園的做法相同。
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.
學者們表示，這不會完全解決與務農相關的所有問題，但如果人們願意吃它，則將有一些幫助。
