Vitamin B12 is extracted from a homogenized sample and the extract is diluted. The diluted extract and standards are applied to the wells of a microtiter plate coated with Lactobacillus delbrueckii subsp. lactis (leichmannii). The growth of the bacteria is dependent on the vitamin content of the sample or standard. Lactobacillus delbrueckii belongs to the lactic acid bacteria and has an absolute growth requirement for the vitamin B12. Thus, this organism is ideal for quantification of vitamin B12 in food and dietary supplements. As a group, the lactic acid bacteria are good candidates for vitamin analysis due to their genetic stability (resistance to undergo mutation), simple metabolic requirements, ease of maintenance and general safety as a nonpathogenic organism.
