摘要

The enumeration of probiotic microorganisms, especially bifidobacteria, is an important and complex topic because of varied nutritional requirements of bifidobacteria and their strict anaerobic nature. The two factors which are very important in detecting and enumerating bifidobacteria are an adequate culture medium and anaerobic conditions. An experiment was done to see the effectiveness of oxygen reducing membrane fragments (ORMF) on recovery of bifidobacteria and other probiotic microorganisms when added in dilution medium. The addition of ORMF in dilution bottles helped recover more counts of microorganisms in four of the five species studied. Hence, ORMF has the potential for improving the growth of probiotic microorganisms.
