The Restoration of microbial cells ought to not differ by a factor increased than two within the calculated price for your standardized inoculum.
On the other hand it hasn't been released in almost any monograph nonetheless. The test is particularly related the place a preparing is exposed to anaerobic or reduced-oxygen problems during use.
