The Nutritional Requirements of some Pasteurella Species

Some Nutritional Requirements of the Genus Ruminococcus.

Deoxyribonucleic acid hybridization among some species of the genus Pasteurella.

The technique of measuring deoxyribonucleic acid (DNA) complimentarity described by B. J. McCarthy and E. T. Bolton (Proc. Natl. Acad. Sci. U.S. 50:156, 1963) has enabled genetic comparisons of various bacteria, viruses, mammals, and other organisms. DNA homologies existing among five species of bacteria now classified in the genus Pasteurella (Bergey's Manual, 7th edition) were studied. The sp...

The nutritional requirements of Acetobacter melanogenum and related species.

During the course of some physiological studies with Acetobacter melanogenum it became necessary to investigate the nutritional requirements of several isolates in considerable detail. Grey and Tatum (1944) already had described a minimal medium for growth of one isolate of this species. However, since only one isolate was studied and the nutritional observations were made more or less incident...

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...
