Microbac routinely performs antimicrobial efficacy tests that meet or exceed industry and governmental standards, both in the U.S. and abroad. However, gaining final regulatory approval is a multi-faceted process, and we are trusted to provide essential services along the way. Clients have relied upon our professional staff to furnish total solutions, from new product research and development capabilities, to final testing for safety and efficacy, or for modification or enhancement of existing label claims.
Since each client has unique needs, the proposed course of action will be decided based upon collaboration between the client's in-house science team and our expert staff. Microbac's expertise includes, but is not limited to, the following areas:
USP 51 - Antimicrobial Effectiveness Testing
The objective is to assess the effectiveness of inherent or added antimicrobial preservatives in a product. The sample is spiked with a known amount of microbial load and depending on product type is analyzed on day 7, 14 and 28.
An initial method suitability is performed to demonstrate at least a 70% recovery of spiked organisms. Method suitability includes determination of an appropriate dilution factor and which in activators are required for the particular product under test. Method suitability is performed concurrently with the AET test and is generally completed by day 5. The information obtained from method suitability is applied to sample analysis on days 7, 14 and 28.
Sample Quantity Required
A 75 mL quantity for a liquid or 75 g of a cream is recommended and is sufficient for both method suitability and AET testing.
Turn Around Time
The test itself requires a minimum of 33 days from initiation and reports are generally issued within 40 days from sample receipt.
The objective is to determine the quantity of mesophilic bacteria and fungi that may grow under aerobic conditions. Mesophilic bacteria grow best at moderate temperatures, typically between 20 and 45°C.
The ability of the test to detect microorganisms in the presence of product must be established. Suitability is generally a onetime test but must be confirmed if a change in the product may affect the outcome of the test is introduced. Method suitability is performed by inoculating the sample with a quantity of a microbial load with individual bacteria and fungi or as a suspension. A control is similarly prepared and analyzed. The responses of the sample and control are compared for acceptance. The acceptance criteria for the plate count method is 50-200% recovery.
Minimum Sample Quantity Required
Unless otherwise directed in the monograph, 10 mL or 10g of material is to be tested. For fluids in aerosol form, 10 containers are sampled. For transdermal patches, 10 units are sampled. Generally it is recommended to submit twice the minimum quantity needed for testing.
Turn Around Time
The turnaround time for regularly submitted samples 10 business days. Expedited testing less than 5 days is not available due to the incubation time required to complete the test. Turn-around time for method suitability generally can be completed in 10 business days but may be extended if the acceptance criteria are not met on the first pass. Expedited testing must be pre-arranged.
USP 62 - Microbiological Examination of Nonsterile Products: Tests for Specified Microorganisms
The objective is to determine the presence or absence of the aerobic microorganisms Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli, Salmonella, Candida albicans, the anaerobic microorganism Clostridium or bile tolerant gram negative bacteria.
The ability of the test to detect the specified microorganisms in the presence of product must be established. Suitability is generally a onetime test but must be confirmed if a change in the product may affect the outcome of the test is introduced. Method suitability is performed by inoculating the sample with a quantity of each specified microorganism of interest individually. The acceptance criteria requires detection of the specified organism. If the acceptance criterion is not met, it may be due to inherent antimicrobial properties of the sample that needs to be neutralized.
Requested Sample Quantity
A submission of 15 mL or g is sufficient for all pathogens except as listed below.
Salmonella: 50 mL or g
Turn Around Time
Ten business days.
A five day expedited TAT is available for all pathogens with prior arrangement. Depending on incubation time, sample may be faster.
The objective is to detect or quantify endotoxins from Gram negative bacteria using amoebocyte lysate from the horseshoe crab. There are three techniques for this test: The gel-clot technique, which is based on gel formulation; the turbidometric technique, based on the turbidity after cleavage of an endogenous substrate; and the chromogenic technique, based on the development of color after cleavage of a synthetic peptide–chromogen complex. Microbac offers the turbidometric technique.
The USP requires that preparatory testing be performed for each product to verify the solution does not interfere with the test. This is a one-time evaluation where the sample is spiked at least in duplicate with endotoxin and a recovery of 50 – 200% must be observed.
Turn Around Time
The turnaround time for regularly submitted samples 10 business days. Expedited testing is available. Turn-around time for Preparatory Testing can be completed in 10 business days but may be extended if the acceptance criteria are not met on the first pass. Expedited testing must be pre-arranged.
Unless otherwise directed in the monograph, 10 mL or 10g of material is to be tested.

Elite scientists at Microbac Laboratories provide their expertise to meet the continual demand for Genetically Modified Organisms (GMO) analysis and detection. GMOs are organisms, usually plants, that have had a portion of their genome modified and are created when foreign genetic material (DNA) is introduced into the host’s DNA. GMOs are typically some type of commercial crop such as tomatoes, soybeans or corn. Microbac’s team utilizes PCR-based analysis of the DNA from these crops to deliver a quick and definitive answer as to whether a sample contains any GMO material.
The introduction of the foreign DNA is usually done to infer resistance in these crop plants to either a naturally occurring disease such as a virus, or to herbicides such as Round Up, but some can be introduced to enhance or reduce other factors in the plants such as flavors or freshness. Specific genetic markers are used in creating these GMO events. It is these markers that are being detected when samples are tested for GMO material.
The experienced team at Microbac has the capability to screen for many common markers used for GMO events such as the 35S promoter and the NOS terminator. Additionally, Microbac has the ability to go further and analyze for specific events themselves such as vector 21-41 found in tobacco or Round Up Ready products found in crops such as corn and soybeans.
Exporters and wholesalers dealing with foreign entities are directly affected by GMO contaminated materials since most governments around the world have either banned or severely limited the importation of GMO materials into their countries. This is especially true of wheat products which are to be GMO free even in the United States. Having a certificate of analysis that guarantees the absence of GMO material in a product makes it less likely that a manufacturer’s product will be held up by customs and ensures that the product is distributed into the marketplace in an acceptable time.
