    摘要： To provide a microorganism or a plant transformed with a β-ionone ring-4-ketolase gene and/or β-ionone ring-3-hydroxylase gene derived from Brevundimonas sp. strain SD-212. The β-ionone ring-4-ketolase gene and β-ionone ring-3-hydroxylase gene produced by Brevundimonas sp. strain SD-212 each have a high activity compared with those of known enzymes, and therefore microorganisms transformed with the genes encoding these enzymes can efficiently produce astaxanthin.

    摘要翻译： 提供转化有来自Brevundimonas sp。的一种β-环庚烯酮-4-酮醇酶基因和/或β-葡萄糖酮 - 环酮-3-羟化酶基因的微生物或植物。 菌株SD-212。 由Brevundimonas sp。生产的β-呋喃酮环酮酮酮酶基因和β-榄香烯环-3-羟化酶基因。 菌株SD-212各自具有比已知酶高的活性，因此用编码这些酶的基因转化的微生物可以有效地产生虾青素。
