BI276 Lecture Notes - Lecture 3: Siderophore, Cellular Respiration, Glycolysis
Document Summary
Macronutrients = c, n, p, s, k, mg, ca, na. Fe siderophore sequestration: iron plays important role in cellular respiration. Two broad classes of culture media: chemically defined, exact chemical composition is known, undefined or complex, uses digested animals or plant products, exact composition not entirely known. Selective medium: contains compounds that selectively inhibit the growth of some microorganisms and not others. Differential medium: contain an indicator which distinguishes between chemical reactions generated by different species of bacteria. Pure culture = contains one single type of microorganisms. Use of semisolid culture allows formation of colonies. Amphibolic pathways = reaction pathways that utilize roles of both catabolism and anabolism. Transfer of atp provides a link between catabolic and anabolic. Recall: chemical composition of a living cell is constantly changing. Free energy = energy released that is available to do useful work.
