DIAPHORASE-LIKE ENZYME IN CULTURE FILTRATE OF CLOSTRIDIUM PERFRINGENS BP6K

The Effect of Clostridium perfringens Type D Culture Filtrate on the Mouse Body Weight

The growth requirements of Clostridium perfringens (welchii) BP6K.

The objectives of the investigation of the nutrition of Clostridiu,m perfringens were twofold. In the first place, the development of a chemically defined medium was prerequisite for the understanding of the factors and conditions favorable to production of t#oxins or exoenzymes. Secondly, it became evident early in the investigation that the organism presented exceptional advantages as a means...

A microbiological procedure for the assay of amino acids with Clostridium perfringens (welchii) BP6K.

In the previous paper on the growth requirements of Clostridium perfringens BPGK it was shown that thirteen amino acids, i.e. arginine, leucine, histidine, isoleucine, methionine, t,hreonine, phenylalanine, tryptophan, valine, glutamic acid, serine, cystine, and tyrosine, are essential for the growth of the organism. The omission of any one of these amino acids from an otherwise complete medium...

Medium for toxin production by Clostridium perfringens in continuous culture.

A tryptone-salts medium for continuous growth and alpha toxin production of Clostridium perfringens type A in an adapted chemostat is described. In such steady-state cultures, fermentative and biochemical activity of C. perfringens remained unchanged. Toxigenic ability to produce alpha, theta, and nu toxins was preserved.
