You take a small suspension of bacteria from a liquid culture, add it to a buffer (we use a glucose solution) and place it in a -50 -- -90 Celsius nitrogen freezer. Easy.

A bacterial culture containing a single species of organisms is referred to as a pure culture. This means that there is only one type of bacteria present in that culture without any contamination from other species. Pure cultures are essential for studying specific bacterial characteristics and behavior.
The CPT code for bacterial vaginosis is 87210 for wet mount, saline preparation.
Changes in the turbidity of a bacterial culture can be measured using a spectrophotometer, which quantifies the amount of light scattered by the culture at specific wavelengths. As bacterial density increases, the culture becomes more turbid, resulting in higher absorbance readings. Additionally, a nephelometer can also be used to measure turbidity by detecting scattered light at specific angles. Both methods provide an indirect assessment of bacterial growth over time.
Agar, a type of red algae, is commonly used to prepare solid culture media for bacterial growth. It solidifies at room temperature, providing a stable surface for bacterial colonies to develop.
Vitrification is the preferred method for the cryopreservation of gametes. It involves freezing them quickly so that ice crystals do not form.

It's a bacterial culture.
Biomaterials and biomolecules needs to be preserved carefully. Enzmes, proteins, inhibors and DNA are normally sored at -20 degrees frozen conditon. For a long time storage of proteins, antibodies, bacterial culture stocks, viral supernatants we use -80degree Celsius. Animal cell lines are normally stored at liquid nitrogen (cryopreservation)
Yes it is. The bacterial culture is the same.
