采用合成氨厂的氨合成气代替纯氢气使脂肪腈加压催化氢化 ，可一步制得双脂肪烃基仲胺。
A new process has been developed to synthesize p-aminophenol methyl ether from p-nitrophenol methyl ether by catalytic hydrogenation, using ammonia synthesis gas instead of pure hydrogen.
该酶对芳香族腈、脂肪族腈、饱和腈与不饱和腈均能作用，并具有较好的对映体选择性。
The enzyme could accept aromatic or aliphatic nitriles, unsaturated or unsaturated nitriles as substrates with high enantioselectivity.
目前已经通过此技术筛选到大量新的功能基因，例如编码脂肪酶、蛋白酶、腈水解酶、氧化还原酶和淀粉酶等活性物质的基因。
Accordingly, the metagenome-based strategy has led to isolation of many novel biocatalysts, such as esterase, lipase, protease, oxidoreductase, nitrilase and amylase.
