Some Nutritional Requirements of the Genus Ruminococcus.

The nutritional requirements of the genus Salmonella.

The nutritional requirements of the Genus Salmonella, especially of such particular members as S. typhi (1, 2), S, gallinarum and S. pullorum(2), etc, have long been investigated. Salmonella organisms were classified by Hohn et al. (3) into two categories, Ammonium strong and Ammonium weak, according to their ability to grow in the ammonium synthetic medium.

Some nutritional requirements for biosynthesis of riboflavin by Eremothecium ashbyii.

Eremothecium ashbyii Guilliermond is a remarkable organism because of its capability of synthesizing relatively large amounts of riboflavin under appropriate conditions. This vitamin is synthesized to a limited extent by a rather wide variety of microorganisms (Pridham, 1952), but those known particularly for their riboflavin producing abilities along with E. a&hbyii are Ashbya gosypi'i (Wicker...
