BEC Growth-Chek™

LexaMed manufactures Growth-ChekTM Microbial Suspensions that are derived from cultures traceable to a recognized culture collection identified in USP; each lot is certified for purity and population (<100 organisms per dose).  These microbial suspensions are specially prepared for simplifying the performance of USP Growth Promotion, Monograph <71>, Bacteriostasis/Fungistasis testing, and other Quality Control Measures for Growth Media. LexaMed has over 30 years of proven performance history in the manufacturing of these microbial suspensions. They are shipped ready-to-use; they require no additional preparation or dilution prior to use. LexaMed can also produce special, made-to-order microbial suspensions. All organisms listed can be manufactured in various concentrations. LexaMed also produces highly concentrated Bacillus subtilis  5230 and Clostridium sporogenes spore suspensions for moist heat validation of heat sensitive products.

Custom Applications

Additionally, LexaMed has initiated a program to help support the enhancement of a company’s Environmental Monitoring Program by preparing custom microbial suspensions from recovered microorganisms from the facility’s environment. We can manage the program, perform trending, assist in the selection of the recovered isolates, perform organism identification, culture and harvest the recovered isolates, retain cultures and microbial stocks and ultimately prepare the custom microbial suspensions at the requested concentration. We have experience working with environmental microorganisms that are often difficult to culture and maintain.

The use of environmental isolates in Growth Promotion testing, disinfectant efficacy studies, preservative effectiveness testing, sterilization resistance studies, screening studies involving objectionable organisms, etc. is considered a best practice among industry leaders and is becoming a regulatory expectation. Let LexaMed simplify your processes while adding robustness to your Environmental Monitoring Program.

LexaMed has recently expanded the Growth-ChekTM Microbial Suspensions product line. We now offer Aspergillus brasiliensis, Bacillus atrophaeus, Bacillus subtilis subsp. spizizenii, Bacillus subtilis 5230, Candida albicans, Clostridium sporogenes, Escherichia coli, Geobacillus stearothermophilus, Kocuria rhizophila, Pseudomonas aeruginosa and Staphylococcus aureus in the ready to use form with a certified population, purity and expiration at custom concentrations ranging from 10^4 – 10^9 CFU/mL. These custom microbial suspensions are derived from cultures traceable to a recognized culture collection identified in USP and are specifically prepared for simplifying the performance of disinfectant efficacy studies, challenge organism resistance studies and other Quality Control Measures. They are prepared ready-to-use at the desired concentration, thus saving you valuable time and money.
