Comprehensive Guide to the Role of Glycerol in Pharmaceutical Microbial Media
Glycerol plays a vital role in the formulation and performance of pharmaceutical microbial media . It is widely used as a carbon source, cryoprotectant, stabilizer, and humectant in microbiological applications. In pharmaceutical microbiology, understanding the functions and correct use of glycerol in microbial media is essential for supporting optimal microbial growth, preservation, and accurate testing outcomes. 1. Introduction to Glycerol Glycerol, also known as glycerin or 1,2,3-propanetriol , is a colorless, odorless, viscous liquid that is highly soluble in water. It is a trihydroxy alcohol derived from natural fats and oils or synthesized chemically. Glycerol is non-toxic and compatible with most biological systems, which makes it highly suitable for use in pharmaceutical and microbiological applications. 2. Chemical Properties of Glycerol Chemical Formula: C 3 H 8 O 3 Molecular Weight: 92.09 g/mol Boiling Point: 290°C Solubility: Completely miscible wit...
