1. Shape and orientation: One of the main differences between agar deeps and agar slants is their shape and orientation. Agar deeps are prepared by allowing the agar medium to cool and solidify in a test tube in an upright position. This results in a cylindrical shape of agar within the tube.
Growth media contain a variety of nutrients necessary to sustain the growth of microorganisms. There are two commonly used physical forms of growth media: liquid media and solid growth media. A liquid medium is called a broth (image 2). Solid growth media usually contains agar (image 1), which is a mixture of polysaccharides derived from red algae.
With the pour plate method, the bacteria are mixed with melted agar until evenly distributed and separated throughout the liquid. The melted agar is then poured into an empty plate and allowed to solidify. After incubation, discrete bacterial colonies can then be found growing both on the agar and in the agar.
