The Equivalence of Pantothenic Acid and p-Aminobenzoic Acid for Growth of Bacterium Linens

THE INFLUENCE OF VARIOUS METABOLITES UPON THE p -AMINOBENZOATE-PANTOTHENATE INTERACTION IN BACTERIUM LINENS

“…Cystine was sterilized alone by filtration or autoclaving. Tubes of media were autoclaved for six minutes at 121 C, inoculated, plugged, sealed, and aerated as described by Purko et al (1951).…”

THE NUTRITIONAL EQUIVALENCE OF PANTOTHENATE AND p -AMINOBENZOATE FOR THE GROWTH OF BACTERIUM LINENS

“…From a nutritional study of 25 strains of Bacterium linens, it was observed (Purko et al, 1951) that one strain (no. 456) is able to grow when either pantothenate or p-aminobenzoate is present.…”

Diversity, Dynamics and Functional Role of Actinomycetes on European Smear Ripened Cheeses

“…It was also shown that yeast strains isolated from the surface of Limburger cheese produced signifi cant amounts of panthotenic acid, niacin and ribofl avin. Purko et al ( 1951b ) demonstrated that biotin was not required for growth by B. linen s in a semi-synthetic medium when either panthotenic acid or p -aminobenzoic acid were present, but the latter two greatly increased the growth rate and cell densities of B. linens . Lubert and Frazier ( 1955 ) demonstrated that the autolysate of yeasts, isolated from the smear of Brick cheese, contained substances that stimulated the growth of Micrococcus caseolyticus (now called Macrococcus caseolyticus , Kloos et al 1998 ) and Micrococcus varians (now called Kocuria varians , Stackebrandt et al 1995 ).…”
