separate individual cells of a particular microbe. This requires the use of a solid medium that provides a surface for the individual cells to be separated and isolated from the other microbial cells that may be present in the original sample. C. Compare your L. acidophilus pour plates and spread plate. Which method do you think worked better to isolate individual colonies? Why? I think spread plates worked best because a solid medium that provides a surface for the individual cells to

AIMS At the end of the experiment‚ students should be able to synthesise pure aspirin using chemical tests such as esterification and recrystallization independently and to also find out the melting point range of aspirin using melting point determination. INTRODUCTION Aspirin‚ which is also known as acetylsalicylic acid‚ is one of the commonly used and widely found in any drugstore or pharmacy. Its properties make aspirin a well-rounded drug that reduces inflammation and fever and also relieves

ISOLATION OF INDIVIDUAL BACTERIAL COLONIES ON SOLID MEDIA Robert Koch developed a method for isolating pure cultures on solid media in 1883. To this end he added agar (a solidifying agent) to liquid nutrient broth; the nutrient broth supports the growth of a wide variety of microorganisms while the agar provides a solid substrate on which bacteria can be mechanically diluted and therefore isolated as independent colonies representing different bacterial species. The isolation of independent bacterial
