[edit] L. casei shirota
- I've removed this text from the main entry as I've been unable to verify the status of L. casei shirota at any of the standard nomenclature sites (here, for example). If anyone can provide a authoritative reference for this sub-species, I'll be happy to integrate the info into the text. MarcoTolo 04:12, 25 March 2006 (UTC)
Discovered in 1930 by Dr Minoru Shirota a Japanese Microbiologist, it was originally isolated form human intestine.
He then went on to begin the very sucessful company that is Yakult Honsha Co. Ltd. in Tokyo.
Appearance: Rods, Gram Positive, Length 1.5-5um, Width 0.4-0.8um. Optimum temperature 37 C.
Highly acid resistant, can stand pH as low as 3, therefore good in the use as a probiotic for hunman ingestion.
Lactobacilli casei shirota are homofermentative and the main products of the metabolism are lactic acid and acetylaldehyde.
There is generally thought to be around an 85-90% utilization of the sugars to lactic acid. L. casei shirota ferment sugars
through the use of various pathways depending on the availability of substrates the main pathway being glycolysis.
Other items produced are Vitamins B1, B2, B6 and B12.
[edit] Research
I don't think that these sentences are suitable for the article. They are too much specific. And when you read the article you feel that it goes suddenly from very general to too specific.
"A team of scientists from Simón Bolívar University, Caracas, Venezuela, have developed a way of preparing beans to reduce flatulence. The researchers found that if beans are naturally fermented with Lactobacillus casei bacteria, they contain lower amounts of the compounds causing flatulence upon digestion. Raffinose, a flatulence-causing compound found in beans, was reduced by 88% with this method. Soluble fibre content went down by over 60%. The amount of insoluble fibre went up 97%.
It has been claimed that patients with gastric troubles should try to avoid L. casei drinks, as the acetic acid produced by these bacteria would worsen one's condition. However, it's worth noticing that gastric problems occur in the stomach, while L. casei live and produce lactic acid in the intestines, and in general, the contents of the digestive tract move from mouth to anus, not the other way."--ArazZeynili 09:56, 1 February 2007 (UTC)
[edit] plagiarism?
The third paragraph for this article has some lines that are exactly the same as the article linked below. Other lines are very similar.

[edit] L. casei Immunitas
The drink DanActive brags incessently about how they have L. casei Immunitas in their drink and how this makes their product incredible. I want to know more about this so I can tell if this product is actually worth buying.AThousandYoung 08:32, 18 May 2007 (UTC)
Dannon has been sued for making claims about the DanActive product. See here: http://www.allheadlinenews.com/articles/7009845724 Meta-Physician (talk) 16:25, 28 January 2008 (UTC)
