shermanii Merger proposal

I was under the understanding that P. shermanii was now classified as a strain of P. freudenreichii. See [1], [2], [3], [4]. The last link mentions Holdeman and Moore 1970 as the ones which reclassified P. shermanii to P. freudenreichii subsp. shermanii. (Unfortunately I don't have access to that reference to check.)

Note that I can't find the spelling "Propionibacter shermani" in any official scientific sources. (e.g. searching the taxonomic databases). Even trying to search PubMed for Propionibacter[All Fields] AND shermani[All Fields] gave no hits, and searching Google Scholar for Propionibacter shermani gave only one hit. The J. Dairy Science article vol 51 no. 5 page 797 "Volatile Compounds Produced by Propionibacterium shermanii" clearly gives Propionibacterium shermanii as the spelling for the bacteria involved with swiss cheese. It is highly likely, therefore, that the "Propionibacter shermani" spelling is a typo. -- 128.104.112.72 (talk) 19:16, 15 November 2008 (UTC)[reply]

I am inclined to agree with you. I think Propionibacter shermani should be deleted and its material should be merged here. I, however, have no knowledge as to how this could be done. Do we need an administrator? 4dhayman (talk) 01:16, 16 November 2008 (UTC)[reply]

You do not need to delete the page (nor do you need an administrator). Simply take the information worth saving, incorporate it into this page, and replace the text of the other page with a redirect. Having a misspelled redirect harms nothing. See Help:Merging and moving pages#Performing_the_merger for more details. -- 128.104.112.75 (talk) 21:57, 26 November 2008 (UTC)[reply]

How, and from what, is it produced?

Can the information of how, and from what, this bacterium is produced, be added to the entry? Apparently it is part of a ingredient called "cultured wheat" that is widely used in the baking industry, but where, and from what, do the producers of "cultured wheat" obtain their Propionibacterium freudenreichii bacteria? 173.89.236.187 (talk) 05:24, 5 August 2015 (UTC)[reply]

(8 years later) Can the information of how, and from what, this bacterium is produced, be added to the entry? Apparently it is part of a ingredient called "cultured wheat" that is widely used in the baking industry, but where, and from what, do the producers of "cultured wheat" obtain their Propionibacterium freudenreichii bacteria? 2605:A000:FFC0:5F:F9BD:9D:B97C:57D4 (talk) 01:30, 25 October 2023 (UTC)[reply]

As a bacterium, and as a living organism, I guess it isn't produced by any external process, but it reproduces asexually by first growing as a result of fermenting the prebiotics in its surrounding, and then dividing itself through (binary) fission. See Bacteria#Growth and reproduction. —Kri (talk) 22:59, 27 June 2024 (UTC)[reply]

Anaerobic?

Since this article says that propionibacterium freudenreichii ferments lactate and not lactate and oxygen, and since the types of cheese that use this type of fermentation are not veined and don't look especially different on the surface than what they do inside, which indicates that the fermentation goes on all throughout the cheese and not only on the surface, does that mean that the propionic acid fermentation is anaerobic, and that the propionibacterium freudenreichii is an anaerobic organism? —Kri (talk) 22:54, 27 June 2024 (UTC)[reply]
