Abstract
A naphthoquinone-dependent strain of Bacteroides melaninogenicus has been used in a microbiological assay to survey bacteria for compounds of the vitamin K group. Organisms known to contain vitamin K, as well as several bacteria that are obligate anaerobes, produced substances which satisfied the naphthoquinone requirement of the assay organism. Vitamin K was chemically isolated from strains of Bacteroides melaninogenicus, Bacteroides fragilis, and Veillonella alcalescens.
摘要
一种依赖萘醌的产黑色素拟杆菌菌株已被用于微生物测定，以检测细菌中维生素K族化合物。已知含有维生素K的生物体以及几种专性厌氧菌产生了满足测定生物体萘醌需求的物质。维生素K是从产黑色素拟杆菌、脆弱拟杆菌和产碱韦荣球菌的菌株中化学分离出来的。
