A simple device for growing Clostridium perfringens and its application in bacteriocin studies.
A simple device constructed of common laboratory material served as a minifermenter for the growth of Clostridium perfringens. A constant flow of nitrogen gas into a culture tube containing C. perfringens assured agitation of the culture and a mechanism for dispensing small volumes of liquid from the culture without disturbing the growth environment. The method was applied to examining the growth-inhibiting effect of bacteriocins of C. perfringens where a very economical use of radioactive isotopes was possible. The activity of some bacteriocins differed when compared with previous data obtained with stationary cultures. Two major categories of bacteriocin appear to exist for this species: those bacteriocins which block the incorporation of DNA, RNA, and protein precursors and those which interfere with the organism's cell wall.[1]References
