Growing bacteria on gel allows for researchers to collect individual colonies much more easily than if they were grown in a liquid medium. See photos. Manual counting of bacterial colony forming units (CFUs) on agar plates is laborious and error-prone. Preparation of Agar Plates Growth and Check of Bacterial Strains. The hardness of a gel medium increases along with it agar concentration, and bacteria move more slowly through hard gel. ... Starch agar plate. H2S colonies will turn. Their growth can be measured by simple observation of how dense their colonies are and how many are present, however more quantitative methods include the use of a counting chamber, or more frequently, viable plate counts.
