标题:生物和化学联合催化从甜菜残渣中生产己二酸
摘要:己二酸是最重要的工业二羧酸之一,主要用作尼龙6,6的前体.当前,商业己二酸主要通过与环境,健康和安全有关的化学途径由苯生产.在此,我们报告了一种通过结合工程化的大肠杆菌菌株和基于re的化学催化剂,从廉价的可再生原料,甜菜残渣中生产己二酸的新工艺.经工程改造的大肠杆菌转化后的d-半乳糖醛酸变成粘酸,很容易被酸沉淀,然后通过氧化络合物催化的脱氧脱水反应,再在温和的条件下pt / C催化的氢化反应,将粘酸进一步转化为己二酸.通过调节the基催化剂的酸度,可以实现对游离酸产物的高选择性.最后,直接从甜菜残渣中生产己二酸,将其用工程化的大肠杆菌和两种化学催化剂进行酶促水解,收率为8.4%,这标志着己二酸生产的新途径.

摘要:The subject invention provides methods for the chemical synthesis of racemic arsinothricin (D,L-AST), the novel organoarsenical antibiotic. One is by condensation of the 2-chloroethyl(methyl)arsinic acid with acetamidomalonate, and the second involves reduction of the N-acetyl-protected derivative of hydroxyarsinothricin (AST-OH) and subsequent methylation of the resulting sodium salt of trivalent arsenic intermediate with methyl iodide. The enzyme AST N-acetyltransferase (ArsN1) was utilized to purify L-AST from racemic AST. This expedient chemical synthesis of AST provides a source of this novel antibiotic for future drug development.
