This experiment concerns with the isolation of streptomycin resistant mutants using a prototrophic Escherichia coli by the use of a simple gradient technique where streptomycin at the rate of 100ug/ml is added in the nutrient agar medium Following a spreadplate inoculation of E coli and incubation for 47 days, the development of bacterial colonies in the high streptomycin concentrationThis experiment concerns with the isolation of streptomycin resistant mutants using a prototrophic Escherichia coli by the use of a simple gradient technique where streptomycin at the rate of 100ug/ml is added in the nutrient agar medium Following a spreadplate inoculation of E coli and incubation for 47 days, the development of bacterial colonies in the high streptomycin concentrationStudents should examine cultures in containers, which have been taped and closed Colony morphology is a method that scientists use to describe the characteristics of an individual colony of bacteria growing on agar in a Petri dish It can be used to help to identify them Colony morphology

How to identify e coli on agar

How to identify e coli on agar-Escherichia coli is commonly found in the lower intestine of warmblooded organisms (endotherms) Most E coli strains are harmless, but some, such as serotype O157H7, can cause serious food poisoning in humans The harmless strains are part of the normal flora of the gut, and can benefit their hosts by producing vitamin K2, and by preventing the establishment of pathogenic bacteria withinBlood agar plate Blood agar plates (BAPs) contain mammalian blood (usually sheep or horse), typically at a concentration of 5–10% BAPs are enriched, differential media used to isolate fastidious organisms and detect hemolytic activity βHemolytic activity will show lysis and complete digestion of red blood cell contents surrounding a colony Examples include Streptococcus haemolyticus
