“…1, IV) and quinolinic acid (Fig. 1, VI ;Goodwin, 1963;Dyke, 1965;Birnbaum, Bottcher, and Samsonova, 1972;Audette et al, 1973;Allegri and DeAntoni, 1974;Gal and Sherman, 1978). For some time this pathway was assumed to be the only one operative in bacteria (Wilson and Henderson, 1960)and fungi (Erge, Gruger, and Mothes, 1962;Beadle, Mitchell, and Nyc, 1947;Bartnicki-Garcia and Nickerson, 1961).…”

“…X. manihotis (bacteria), [Vol. 66 (Lingens and Vollprecht, 1964;Ahmad and Moat, 1966;Lingens et al, 1966;Birnbaum et aI., 1972;Audette et al, 1973). On the other hand, in Streptomyces venezuelae (bacterium), Saprolegnia ferax (Phycomycete), Saccharomyces cerevisiae (yeast) grown under anaerobic conditions, Xanthomonas trifolii, Pseudomonas aeruginosa, P. iodinum and Mycobacterium phlei (bacteria), tryptophan is not converted into niacin (Lingens and Vollprecht, 1964;Ahmad and Moat, 1966;Lingens et al, 1966).…”
