The effects of two transport systems and cryoprotective agents on the survival of bacteria in ground beef samples were evaluated. Survival of Clostridium perfringens in ground beef samples after simulated transport (72 h) was higher (about 99%) in Dry Ice than in Trans Temp shipping units (-3 degrees C). There were no significant differences between the two transport systems in survival of coliforms, Escherichia coli, Staphylococcus aureus, or aerobic bacteria. Mixing ground beef samples at a ratio of 1:1 (wt/vol) with 10, 20, or 30% buffered solutions of dimethyl sulfoxide or glycerol before freezing improved the survival of C. perfringens and coliforms in both transport systems. Recovery of E. coli was significantly higher with the addition of 10% dimethyl sulfoxide before Dry Ice transport. Addition of 10% dimethyl sulfoxide resulted in a 100% recovery of both S. aureus and aerobic bacteria from ground beef after simulated transport in Trans Temp shipping units. The use of cryoprotective agents can improve the survival of bacteria during transport of ground beef samples. 相似文献

F. SCHVED, M.D. PIERSON AND B.J. JUVEN. 1996. When used separately, 20 mmol 1-1 maltol or 1600 AU ml-1 nisin resulted in a 0–0.6 log10 reduction in viable counts of Escherichia coli in a buffer system. However, when added in combination they yielded a 1.8–5. 5–log-cycle reduction in viable counts of E. coli at pH 5.0 and 6.8 respectively. It is postulated that maltol (and ethyl maltol) destabilizes the cell outer membrane by chelation of Mg2+ and/or Ca2+ , thus permeabilizing the E. coli cell to nisin. 相似文献

The zygomycoses are fungal infections often occurring in compromised hosts. We report the first culture-proven case of a gastrointestinal infection in the United States by Basidiobolus haptosporus (ranarum). The clinical and histological features are noted in order to distinguish this infection from the more widely reported mucormycosis. 相似文献
