Abstract

The main carotenoid of Flavobacterium strain R1560 has been identified as (3R,3'R)-zeaxanthin. Also present were small amounts of 15-cis-phytoene, phytofluene, "zeta-carotene" (7,8,7',8'-tetrahydro-psi, psi-carotene plus 7,8,11,12-tetrahydro-psi, psi-carotene), neurosporene, lycopene, beta-zeacarotene, gamma-carotene, beta-carotene, beta-cryptoxanthin, rubixanthin, 3-hydroxy-beta-zeacarotene and several apo-carotenals. Zeaxanthin production was inhibited by nicotine (10 mM), and lycopene and rubixanthin accumulated. The biosynthesis of zeaxanthin is discussed in terms of pathways and also of "half-molecule" reaction sequences. The presence of zeaxanthin may be a characteristic of a group of Flavobacterium species, and may thus be useful in the taxonomic classification of these organisms.

摘要

黄杆菌菌株R1560的主要类胡萝卜素已被鉴定为（3R,3'R）-玉米黄质。同时还存在少量的15-顺式-八氢番茄红素、六氢番茄红素、“ζ-胡萝卜素”（7,8,7',8'-四氢-ψ,ψ-胡萝卜素加7,8,11,12-四氢-ψ,ψ-胡萝卜素）、神经孢菌红素、番茄红素、β-玉米胡萝卜素、γ-胡萝卜素、β-胡萝卜素、β-隐黄质、玉红黄质、3-羟基-β-玉米胡萝卜素和几种脱辅基类胡萝卜醛。尼古丁（10 mM）抑制了玉米黄质的产生，番茄红素和玉红黄质积累。从途径以及“半分子”反应序列方面讨论了玉米黄质的生物合成。玉米黄质的存在可能是一组黄杆菌属物种的特征，因此可能有助于这些生物的分类。
