The vitamin requirements of 46 strains representing nine species of Staphylococcus isolated from human skin together with nine authentic reference strains of these species were determined using a chemically defined medium. Strains of Staphylococcus saprophyticus and Staphylococcus cohnii were isolated on selective media. All the strains investigated required nicotinic acid and thiamine for growth. Biotin was essential or stimulatory for all coagulase negative strains except one strain of Staphylococcus capitis. Oleic acid substituted for biotin in all cases except with one strain of Staphylococcus haemolyticus. No species pattern of biotin requirement or of the ability of oleic acid to substitute for biotin was apparent. Five out of six strains of Staph. cohnii required pantothenic acid.
