Molds, spores and other microbes grow at wildly varying rates and thrive in different temperatures. Selecting the correct incubation parameters is critical for microbiologists looking to thoroughly detect their products' microbial burdens. For tests such as environmental monitoring, regulatory guidelines offer a range of incubation strategies.
The following are considered best practice selections:
Moving from the traditional test method to a rapid method offers an opportunity to revisit the current incubation strategy with an eye to achieving results more efficiently and effectively than traditional methods. Automated rapid technologies such as the Growth Direct™ System can help with this determination.
The sensitivity of microorganisms to incubation temperature is well known, however there are several different incubation strategies used within pharmaceutical quality control labs that monitor environmental contamination. There is always a balance to be struck between incubation times and risk. As environmental monitoring is a trending study sometimes a quantitative response is not required.
Automated technologies such as the Growth Direct™ System, provide unique insight into the growth characteristics of the natural flora, which enables a better rationale for the selection of the final incubation strategy. Using data as part of the validation process, a serial incubation strategy could potentially be eliminated for a single temperature option--reducing days and requiring a single incubator.
Faster Times to Results with Automated Enumeration
Quality control departments are capable of realizing faster times to results. Automated, growth-based methods automate the time-tested compendial method and do not require reagents or unique sample preparation techniques.
