Product Description<br />

The Bacto Proteose Peptones are enzymatic digests of protein. Studies of peptic digests<br />

of animal tissue prepared under varying digestion parameters led to the development<br />

of Proteose Peptone, Proteose Peptone No. 2 and Proteose Peptone No. 3. Data accumulated<br />

during these studies demonstrated that no one peptone is the most suitable<br />

nitrogen source for every microbiological application. Bacto Proteose Peptone No. 4 is a<br />

spray-dried version of Bacto Proteose Peptone.<br />

BiTek Proteose Peptone and BiTek Proteose Peptone No. 3 are enzymatic digests of<br />

protein, developed to offer alternatives to the Bacto Proteose Peptones for scale-up to<br />

production applications.<br />

Applications<br />

Bacto Proteose Peptone is used in preparing microbiological culture media and in<br />

producing bacterial toxins. Bacto Proteose Peptone was originally developed to produce<br />

a diphtheria toxin of high and uniform potency from cultures of Corynebacterium<br />

diphtheriae. Studies support the use of Proteose Peptone for production of diphtheria<br />

toxin, toxin-antitoxin mixtures and toxoid. 1,2 Proteose Peptone is also valuable in the<br />

production of other bacterial toxins: Clostridium botulinum toxin; 3 toxin from Clostridium<br />

perfringens; 4 toxin of hemolytic streptococci; 5 pneumococcus toxin; 6 and toxin from<br />

Salmonella pullorum (Salmonella cholerasuis subsp. cholerasuis). 7<br />

Many factors account for the suitability of Proteose Peptone for the culture of fastidious<br />

pathogens, including the nitrogen components, buffering range and the high content<br />
