VITAMIN K COMPOUNDS IN BACTERIA THAT ARE OBLIGATE ANAEROBES

Science. 1964 Dec 4;146(3649):1307-9. doi: 10.1126/science.146.3649.1307.

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.
