Culturing Microorganisms



Although the use of aseptic techniques is required for those taking Biology triple, all students are expected to know how to ‘investigate the effectiveness of antimicrobial agents on bacterial growth’. This is practical activity 7 for Biology, and practical activity 5 for Combined students. To culture bacteria to carry out this practical activity, aseptic techniques need to be used. For this reason this video is available for combined students as well as Biology triple students. It is worth watching this video alongside the ‘preventing and treating communicable diseases’ video in the run up to the exams.
