<P> It is often essential to isolate a pure culture of microorganisms . A pure ( or axenic ) culture is a population of cells or multicellular organisms growing in the absence of other species or types . A pure culture may originate from a single cell or single organism , in which case the cells are genetic clones of one another . For the purpose of gelling the microbial culture , the medium of agarose gel ( agar ) is used . Agar is a gelatinous substance derived from seaweed . A cheap substitute for agar is guar gum , which can be used for the isolation and maintenance of thermophiles . </P>
