U40 supplement from HiMedia is a filter-sterilized urea solution (5 ml per vial) used to detect urease activity in microbiological media. It's specifically recommended for use with Urea Agar Base (Christensen) and is a key component in identifying urease-positive organisms, particularly Proteus vulgaris. The supplement is a slight modification of the Christensen formulation and is recognized by the Bureau of Indian Standards (BIS). Here's a more detailed breakdown: 

• Function:U40 supplement is used to detect urease activity, which is the ability of an organism to produce the enzyme urease, which breaks down urea.
• Composition:Each vial contains a urea solution, sufficient for 100 ml of medium.
• Application:It's commonly used with Urea Agar Base (Christensen) for identifying bacteria, especially Proteus vulgaris, which is a rapid urease producer.
• Benefits:The supplement helps differentiate between various urease-positive organisms, including those from the Enterobacteriaceae family, and those that are not.
• Standards:The supplement's use is also recommended by the Bureau of Indian Standards under the specifications IS:5887(Part I)-1976.
• References:Several publications, including those by Christensen, MacFaddin, and the Bureau of Indian Standards, are referenced in its application.
