菲勒补充道，也可能能够从无法产生指纹的变形表面上找到大量有用的细菌基因序列。

Fierer adds that it may be possible to retrieve useful amounts of bacterial gene sequences from textured surfaces that won't yield fingerprints.

十年之后的现在，通过对海洋细菌的变异分析，首个直接证明变形菌视紫质功能的证据被发现。

Now, a decade later, the first direct evidence for the functioning of proteorhodopsin in native marine bacteria is presented, based on mutational analysis in a marine bacterium.

在2000年，美国的科学家发现一些海洋细菌的基因组中包含的一种基因能够能够编制一种新的光色素：变形菌视紫质。

In 2000, American scientists discovered that many Marine bacteria contain a gene in their genome that encodes a new kind of light-harvesting pigment: proteorhodopsin.
