Can bacteria grow in glycerol
WebFeb 23, 2024 · Bacteria preservation in glycerol is one of the common method for maintaining bacterial strains over long periods of time. This method involves adding glycerol to a bacterial culture and freezing it at a low temperature (-70°C or lower) to create a stable stock which one can store for years without losing viability. WebSome bacterial strains can be stored for up to 1 year at 4°C in agar stab cultures, which are especially useful for transporting samples to other research facilities. Stab cultures are …
