Pseudomonas aeruginosa Added to Microbiologics EZ-CFU Quantitative QC Microorganism Product Line for Growth Promotion Testing

Leading producer of ready-to-use quality control microorganisms, Microbiologics Inc., has added Pseudomonas aeruginosa ATCC® 9027™ to their popular EZ-CFU™ product line. EZ-CFU™ is designed for performing Growth Promotion Tests of microbiological culture media as described in the United States Pharmacopeia (USP), European Pharmacopoeia (Ph. Eur.) and Japanese Pharmacopoeia (JP). Pseudomonas aeruginosa ATCC® 9027™* is listed as one of the compendial challenge microorganisms for the Growth Promotion Test.

Chief Operating Officer of Microbiologics, Donna Scholer, comments, “We are very excited to have this Pseudomonas strain available in our EZ-CFU™ product line because it has been a popular customer request.” Scholer continues, “EZ-CFU™ is one of four distinct product lines Microbiologics manufactures for Growth Promotion Testing. With each product offering unique features and benefits, we are able to meet each customer’s individual needs in terms of test volume, preparation time, and ease-of-use.” Microbiologics, in business for more than 40 years, produces a broad range of ready-to-use quality control microorganism preparations. The company specializes in products for microbiological testing within industries such as clinical, medical device, pharmaceutical, cosmetic, food, and water. 

The purpose of the Growth Promotion Test is to determine the suitability of culture media that is used in pharmaceutical tests. The test is performed by inoculating the media with a small number of microorganisms (less than 100 colony forming units) to ensure the nutritive properties of the media are adequate to support even a small number of microorganisms. Pseudomonas aeruginosa is a fastidious microorganism that is notoriously difficult to grow. For this reason, it is an ideal strain to use for the Growth Promotion Test because it will meaningfully challenge the media. The EZ-CFU™ product line from Microbiologics is designed to deliver 10-100 colony forming units per 0.1 ml of hydrated suspension.
