Anaerobic incubation system, Anaerocult®

Dodavatel: Merck

Popis: Anaerocult® system is a reliable and established system for the cultivation of obligate and facultative anaerobes. The Anaerocult® system is based on sachets made of highly absorptive and highly gas permeable paper. The sachets, of different sizes, are filled with an oxygen-binding reagent mixture which also produces carbon dioxide. Water is added to start the reaction, which consists of the oxidation of finely divided iron and release of CO₂. The reaction proceeds without a catalyst. Incubation is possible in an anaerobic jar or in bags.

Multiformat plates, silica gel 60, unmodified layers, glass backed

Dodavatel: Merck

Popis: Merck Multiformat plates are pre-scored glass plates for easy breaking into various sizes. The plates use the same silica coating as the corresponding TLC or HPTLC plate delivering chromatograms that are identical to those of the non scored plates.

Base materials

Dodavatel: Merck

Popis: Merck products offer high quality for applications in the microbiology field.

Enterobacter sakazakii agar, Chromocult®

Dodavatel: Merck

Popis: Selective medium for the detection of Enterobacter sakazakii in milk powder and powdered infant formula. The base in Chromocult ® Enterobacter sakazakii agar allows good growth and strong colour formation of E. sakazakii colonies. The addition of inhibitors and the incubation temperature of 44 °C largely reduce the growth of the majority of gram-positive and gram-negative accompanying flora. E. sakazakii is ß-D-glucosidase positive and grows as blue-green colonies on this medium. Incubation: 24 ±2 hours at 44 ±1 °C. Incubation temperature has a strong influence on sensitivity and selectivity of this method. Temperatures higher than 45 °C will inhibit the growth of E.sakazakii. Temperatures below 43 °C will reduce inhibition of accompanying bacteria.
