Unformatted text preview: doubling time is a constant The growth rate is exponential and depends on the growth factors The final number in a population is equal to the initial number x 2 raised to the power that is the number of generations that have occurred Bacterial Growth Bacterial Growth If you start with 50 cells how many will you have at the end of 9 generations? 50----100---200--- 400---800---1600---3200---6400---12800---25600 25,600 Media For Bacterial Growth Media For Bacterial Growth Nitrogen source Carbon, hydrogen Vitamins as cofactors or carrier molecules Minerals salts , electrolytes , ions Water cells are 80% or more water Liquid media , solid media , plates or tubes Types of Culture Media Types of Culture Media General purpose Selective Differential Transport Chemically defined or synthetic assay Enrichment Enriched Mold plating...
