Biphasic system for growing bacteria in concentrated culture.
The concentration of masses of pathogenic bacteria can be simplified by growing them in a confined environment with diffusional access to a reservoir of nutrients. Culturing them on an agar or membrane surface accomplishes this; however, the total cell yield often is low, the cells probably are not physiologically uniform, and difficulty may occur in dislodging them. The concentration of cells ...
متن کاملBiphasic resin system for growing concentrated cultures of microorganisms and its application to the cultivation of Neisseria gonorrhoeae.
A technique is described in which a polyester casting resin is used instead of agar for the growth of Neisseria gonorrhoeae in a biphasic system. In complex medium, higher concentrations and stability of T1 colony type were obtained with resin than with either agar or broth alone after 24 h of incubation. In defined medium, the growth of gonococci and colony type stability were similar in singl...
متن کاملConventional Biphasic Broth Blood Culture System
In a comparative fungal blood culture study, a lysis-centrifugation system (Isolator; Du Pont Co., Wilmington, Del.) detected 89% of all episodes of fungemia; the lysis-centrifugation system detected fungemia exclusively or significantly earlier than did a biphasic brain heart infusion bottle system 83% of the time. The lysis-centriguation system was particularly useful in the early detection o...

Gerhardt, Philipp (The University of Michigan, Ann Arbor), and D. M. Gallup. Dialysis flask for concentrated culture of microorganisms. J. Bacteriol 86:919-929. 1963.-A twin-chambered dialysis flask was designed with a supported membrane clamped between a reservoir of medium in the bottom and a small volume of culture above, the unit being mounted on a shaking machine to provide aeration and ag...
متن کاملBiphasic culture of Arcobacter spp.
Arcobacter spp. have recently been genetically differentiated as a genus distinct from Campylobacter. Physiologically, Arcobacter spp. are aerotolerant bacteria, while Campylobacter spp. are microaerophilic. However, since Arcobacter spp. have been difficult to grow to high population densities in broth media, alternative culture techniques were investigated. A biphasic culture system was devel...
