When did the change of official name from Lactobacillus sanfrancisco to Lactobacillus sanfranciscensis happen? An answer ((to the exact day OR within a few days) AND the name of the conference at which it happened) would be appreciated.

Lactobacillus sanfranciscensis first shows up in pubmed in Gänzle et al. (1998). They reference Trüper and De'Clari (1997) for the name Lactobacillus sanfranciscensis. The latter say:
As none of them makes sense in the nominative apposition construction, we hereby correct these names to forms that are in agreement with Rule 12c as follows.
...
Lactobacillus sanfrancisco ("the city San Francisco") is corrected to Lactobacillus sanfranciscensis (adjective: "from San Francisco").
That issue of Int J Syst Bacteriol was published 1 July 1997, so I guess that's your date.
