Bacterial contamination has once again resulted in a large scale product recall, this time with baby wipe; and this is an entirely avoidable problem. Apparently, after opening a package of baby wipes, customers discovered the wipes were discolored and had an unpleasant order. Further microbial testing indicated that the contaminant was (in part) Burkholderia cepacia. A […]

Its been a busy year at the lab, and we hope for you as well. As we look forward to 2013, here’s a few of the projects we were working on in 2012. Anti-Fungal Turf Testing Brown and Dollar Spot Fungi Aspergillus Fungi Close up of spores on the go Military Textiles AATCC […]
2012 – Year in Review
Of the more prominent challenges facing the construction industry are those related to deterioration of material and structures by actions of microorganisms. The process is loosely known as Microbial Induced Corrosion (MIC), which belies an incredible range of processes occurring as a result of the growth of microorganism, principally bacteria, on our steel and concrete […]
Concrete & the Challenge of Microbial Induced Corrosion
Formaldehyde is the most basic form of aldehyde representing the class of reactive antimicrobials. Situ Biosciences – Microbial Test Experts Did you know? Formaldehyde and aldehydes can be volatile at room temperature leading to the odor commonly associated with preservation of tissue or tissue samples such as in laboratories, hospitals, and mortuaries.
Antimicrobial Preservatives and Additives – Aldehydes
Microbial Product Testing 1.0 If you’re new to microbial testing, it can be confusing as to which test(s) are needed, necessary, or required. “Which test do I need?” – Is a seemingly simple question, but the reality is that the requirements for a particular product can be complex.
First Steps to Microbial Product Testing
A Guide to Microbial Testing: Microbial Control vs Microbial Elimination For Additional Guidance: First Steps to Microbial Product Testing In antimicrobial systems or microbiology testing, confusion arises when a particular system is being evaluated since the acceptable concentration of microorganisms for any particular process can differ.
Assessment & Control of Microbial Contamination
The Microbial Rule of 3…. The “Rule of Three” simply stated is – Does the system have Water, Temperature, and Carbon? If ‘yes’ then the product or system will be challenged by microorganisms.
Antimicrobials: Improving Microbial Control
or “Which antimicrobial is best?” …unfortunately it’s not so simple. Product manufacturers have a challenging task when it comes to selecting antimicrobials for their products. Very few manufacturers have access to either in-house microbiology or formulation experts, or contract laboratories that have both microbial facilities and sufficient expertise in their product requirements. Details matter. For […]
