Description
Scientific Principal
PDX-LIB contains a patented formula of antibiotics, growth enhancers and color- changing compounds. The antibiotics function synergistically to inhibit most non-Listeria microorganisms. Growth enhancers provide recovery nutrients to support the growth of sub-lethally injured Listeria. Indicator compounds will turn the broth from yellow to black when converted by beta-glucosidase enzyme produced by Listeria species. A brown to black color 30-48 hours at 37oC indicates a presumptive positive test for Listeria spp. Positive results can be read as early as 30 hours. Results cannot be considered negative until samples have been incubated for 48 hours.
