Subculturing can be contaminated by introducing microorganisms from the surrounding environment, using non-sterile techniques, or having contaminated equipment or media. It is essential to maintain sterile conditions, work in a clean environment, and properly handle and sterilize equipment to prevent contamination during subculturing.

Flaming sterilises the tube.
Subculturing from the top of the Selenite broth after incubation is done to isolate the target pathogen, such as Salmonella or Shigella. These bacteria are known to accumulate on the surface due to their characteristic growth patterns. By subculturing from the top layer, it increases the likelihood of obtaining a pure culture for further identification and testing.

Each cell line or cell type expresses different characteristics in terms of growth and appearance in culture. Many cell lines grow as a single sheet monolayer attached to both themselves, and the culture vessel. Other cell types exist as single cells or clumps of cells suspended in the growth medium. Both adherent and suspension cultures must be maintained regularly to prevent overgrowth and accelerated cell death from exhausted medium and to promote the growth of the next generation of cells. Viable subcultures may be obtained by transferring a particular volume of cells to new culture vessels with fresh medium. These fresh cultures are allowed to grow and divide as normal until such time the culture reaches confluence and the cells are used for experiments or subcultured.
