Practise culturing microorganisms by explaining aseptic technique, safe transfer, incubation conditions and contamination control.
Two students, student P and student Q, each cultured bacteria in a liquid medium for 20 hours. The culture conditions used by both students were identical. Every two hours, each student removed a sample of the culture to count the number of bacteria. Each student used a different method to count the number of bacteria in the samples. The graph shows the bacterial growth curve that each student drew using their results. number of bacteria per
Both students used aseptic techniques to culture the bacteria.
Explain the importance of using aseptic techniques to culture bacteria.
Explain one aseptic technique that should be used when culturing bacteria.
