Plating of bacteria. Hands of a laboratory technician streaking bacteria onto an agar growth medium in a petri dish. These petri dishes are filled with different coloured agar nutrient mediums upon which bacteria are grown. The small bottles (top right) contain bacteria. Using a platinum wire loop,the laboratory technician streaks a specific type of bacteria in parallel lines across the agar. These lines are crossed and recrossed at different angles,diluting the culture until colonies form around a single bacterium. Streaking is a technique for isolating strains of bacteria from mixed cultures,which are then incubated and grown in pure form | |
