Science:肠道微生物帮助食草动物代谢植物
  • 纯植物性饮食很难满足人类所需的所有能量和营养素,而食草动物却不一样;
  • 在最近一次整合和比较生物学学会的年会上,研究者确信:微生物对于食草动物来说,具有更多深入的作用;
  • 一种细菌可以帮助热带蚂蚁循环利用植物物质中缺乏而又对合成蛋白质至关重要的氮;
  • 另一种细菌帮助金花虫分解它们吃进去的叶子的细胞壁;
  • 而第三类是细菌联盟,它们帮助林鼠消化充满毒素的沙漠植物,这个发现还有可能帮助得肾结石的人类。

Abstract:收起
No matter what a vegan may tell you, a solely plant-based diet is a tough way to get all the calories and nutrients you need. Unless you have the right microbial partners. At the recent annual meeting of the Society for Integrative and Comparative Biology, researchers made it clear that microbes lend a wide array of other talents to herbivores. One gut microbe helps a tropical ant recycle nitrogen, which is scarce in plant matter and is vital for making proteins. Another aids leaf beetles by breaking down the cell walls of the foliage they consume. And a third set of microbial allies explains how pack rats can munch on toxin-filled desert vegetation—a discovery that may suggest ways to thwart kidney stones in people. The work is showing just how broadly important microbes are in the animal kingdom.
