The presence of vitamin B 12 in basal media at nm and µM levels indicates that its delivery via cell culture media is complex. Complex culture media is a type of nutrient for growing bacteria that does not have exact composition. Viruses, for example, are obligate intracellular parasites and require a growth medium containing living cells. If you are just trying to grow something up, or reactivate a freeze dried culture, then complex media is a good choice for this reason. An undefined medium has some complex ingredients, such as yeast extract or casein hydrolysate, which consist of a mixture of many chemical species in unknown proportions.
