nitrocefin , however , demonstrated an unexpected and uniquely potent activity against streptococcus faecalis ( minimum inhibitory concentration , less than or equal to 0.06 to 0.12 microgram/ml ) the relative hydrolysis rate of padac when subjected to six different beta-lactamases was substantially greater than that of cephacetrile , but less than that of nitrocefin .
