Lower water activity may also stop microbial growth inside pharmaceutical preparations, see also Sect.
of fairly low molecular weight can be employed for a therapeutic agent in restoring blood volume [forty eight].
Quorum sensing will be the regulation of gene expression in response to fluctuations in cell-population density.
The received microbial counts are then compared with predefined acceptance standards. These criteria are usually established based upon regulatory specifications and enterprise-certain high-quality requirements. In case the microbial counts exceed satisfactory limits, more investigation is initiated.
