一、转化L-山梨糖成2-酮-L-古龙酸(KGA)的微生物众所周知,很多微生物均可使L-山梨糖氧化成KGA。这类微生物包括以下的属:Acetobacter、Aerobacter、Alcaligenes,Azotobacter、Bacillus、Escherichia、Gluconobacter、Klebsiella、Micrococcus、Pseudomonas、Serratia和Xanthomonas。其中Acetobacter、Gluconobacter及Pseudomonas是最活跃的生产性微生物。在Pseudomonas Putida ATCC 21812和Gluconobacter melanogenus IFO 3293的细胞提取物试验中,首次发现了L-山梨糖通过L-山梨糖酮转化成KGA的方法。试验表
First, the conversion of L-sorbose into 2-keto-L-gulonic acid (KGA) microorganisms It is well known that many microorganisms can make L-sorbose oxidized to KGA. Such microorganisms include the genera: Acetobacter, Aerobacter, Alcaligenes, Azotobacter, Bacillus, Escherichia, Gluconobacter, Klebsiella, Micrococcus, Pseudomonas, Serratia and Xanthomonas. Among them, Acetobacter, Gluconobacter and Pseudomonas are the most active productive microorganisms. In the cell extract test of Pseudomonas putida ATCC 21812 and Gluconobacter melanogenus IFO 3293, a method of converting L-sorbose to KGA by L-sorbosone was found for the first time. Test table
