D - amino acids as unnatural chiral products are important intermediates in the synthesis of products , such as - lactam semisynthetic antibiotics , antiviral agents , artificial sweeteners , pesticide , peptide hormones , and pyrethroids , etc . though bioconversion of d - amino acids using microbial cells has been realized in industrialization for decades , some limited factors hinder the development of d - amino acid production , and ultimately result in shortage of the raw material in the related industrial fields 目前,用微生物菌體轉化生產d -型氨基酸的工藝路線已經產業化,但天然菌體轉化工藝存在一些限制因素,阻礙了d -型氨基酸的擴大生產,導致產品短缺。因此,利用基因工程菌生物轉化d -型氨基酸已成為世界氨基酸產業的新潮流。

In contrast tothe semisynthetic penicillins , these drugs tend to have good resistance to ? lactamases 這些藥物往往在抗?內酰胺酶方面有良效。
