[edit] Name change?

I understand the name was recently changed to Bacillus Atropheus as part of a standardizing process. Perhaps someone with more knowledge of wikipedia could rename or redirect or whatever.

Actually, two reference strains that had been classified as B. subtilis were re-classified based on DNA homology testing as a new species, B. atrophaeus (Nakamura 1989). In other words, just a couple of B. subtilis strains were affected. (see original citation). MarcoTolo 21:07, 11 March 2006 (UTC)

[edit] Common name?

what's the common name of Bacillus subtilis?

That I'm aware of, Bacillus subtilis doesn't have a "common name". -- MarcoTolo 00:08, 26 July 2007 (UTC)

[edit] Ropiness

Under Pathogenesis, what is "ropiness" caused in bread?? 202.36.179.66 23:11, 25 July 2007 (UTC)

"Ropiness" occurs when bacterial contamination leads to mucus-like, sticky, and stringy dough - i.e. like lots of little ropes. The condition is caused by the production of long chain polysaccharides by the bacteria. -- MarcoTolo 00:08, 26 July 2007 (UTC)

Bacteria in nature are commonly colonial living and dependent on each others excreation of reagents essential for energy production. Only a few bacteria species can without hazzle be grown in laboratory because of the required colonial symbiosis. The Polysaccharide excreted creates a web like structure of very sticky goo(No material has yet been found where this goo will not stick) which create the habitat of bacteria colonies.

[edit] Use in Probiotic Products

I would like to see some discussion of the use of bacillus subtilis in a number of probiotic products including Primal Defense and ThreeLac (also FiveLac from the same company). The maker of a competing probiotic product is distributing literature claiming that bacillus subtilis can be harmful according to some studies. —Preceding unsigned comment added by 71.198.221.25 (talk) 02:10, 8 November 2007 (UTC)

[edit] Amylase/Lipase Testing

Is it worth mentioning at the top that it is amylase and lipase positive as these are some simple tests that can be done to differentiate between common bacterial species. TheTrojanHought (talk) 19:28, 28 January 2008 (UTC)
