The diluted extract and standards are applied to the wells of a microtiter plate coated with \u003cem\u003eLactobacillus rhamnosus\u003c\/em\u003e. The growth of the bacteria is dependent on the vitamin content of the sample or standard. \u003cem\u003eLactobacillus rhamnosus\u003c\/em\u003e belongs to the lactic acid bacteria, and has an absolute growth requirement for the vitamin B2 (Riboflavin). Thus, this organism is ideal for quantification of vitamin B2 (Riboflavin) 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 non-pathogenic organism.\r\n\u003cbr\u003e\u003ch3\u003eBenefits:\u003c\/h3\u003e\r\n\u003cul\u003e\r\n \t\u003cli\u003eExternal Certificate AOAC-RI 100902.\u003c\/li\u003e\r\n \t\u003cli\u003eThe test system is very robust and well suited for routine analysis.\u003c\/li\u003e\r\n \t\u003cli\u003eThe VitaFast® test kits feature uniform procedures across the product line.\u003c\/li\u003e\r\n\u003c\/ul\u003e\r\n\u003cspan style=\"color: #ffffff\"\u003e.\u003c\/span\u003e","brand":"R-Biopharm","offers":[{"title":"Default Title","offer_id":53657888227619,"sku":"RBIOP1007","price":769.0,"currency_code":"NZD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0597\/5896\/9012\/files\/P1007.jpg?v=1779863206","url":"https:\/\/onelab.co.nz\/products\/vitafast%c2%ae-vitamin-b2-riboflavin-en","provider":"Onelab","version":"1.0","type":"link"}
