Minute 2. Record of attendance. The members present were: B. Biavati (Deputy Chairman), J. Björkroth, C. Bonaparte (Acting Secretary), F. Dellaglio (Chairman), L. M. T. Dicks (Deputy Chairman), C. Franz, B. Pot. Apologies for absence were received from: G. Felis, W. P. Hammes, W.-H. Holzapfel, G. Klein (Secretary), G. Reuter, B. Sgorbati. The guests present were: Akihito Endo, Paola Mattarelli, K. Watanabe and Elisa Salvetti.

Session 2. Closed meeting Minute 5.Call to order.The Chairman, F. Dellaglio, called the closed meeting to order at 17 : 00 on 1 September, 2006.Minute 9. Membership.Notices of intentions to resign were received from the following members: A. Kagermeier-Callaway, E. Lauer and M.-C.Montel.The subcommittee accepted the resignations.The chairman and all present members of the subcommittee expressed their gratitude for the work and contributions of the retiring members.E. Ringø was considered as a candidate, provided that he would be present at the next meeting with a presentation at the open meeting.K. Itoh was asked to consider himself or another Japanese colleague as a potential candidate for the subcommittee.Other possible candidates were also discussed.The members also agreed to exclude inactive members if they do not attend meetings and/or do not contribute further to the work of the subcommittee.The secretary was asked to write a letter to such members indicating their exclusion from the subcommittee.
Minute 10.Scope of the Subcommittee.The status quo of genera within the purview of the subcommittee is as follows: Bifidobacterium, Lactobacillus, Aerococcus, Carnobacterium, Leuconostoc, Pediococcus, Tetragenococcus, Weissella, Oenococcus, Vagococcus, Gardnerella, Paralactobacillus, Scardovia and Parascardovia.The subcommittee proposed that the new genera Isobaculum, Aeriscardovia, The origin of the type strain of Bifidobacterium animalis subsp.lactis (the former species Bifidobacterium lactis) remains unclear (isolation from yoghurt or re-isolation).The subcommittee will prepare a Taxonomic Note concerning the designation of a neotype strain.
The Judicial Commission has rejected a formal request introduced by B. Pot and supported by the subcommittee [Klein, Int J Syst Evol Microbiol 56 (2006), 2501-2503] regarding the Lactobacillus casei-group.The proposal to reject the species Lactobacillus paracasei, to designate strain ATCC 334 as the neotype of L. casei and to reclassify the current type strain of L. casei ATCC 393 was rejected.
The separate species status of Lactobacillus animalis and Lactobacillus murinus has been confirmed by M. Vancanneyt through DNA-DNA hybridization studies.L. animalis LMG 9843 T and L. murinus LMG 14189 T show a binding level of 56 % (standard deviation of 2 % between reciprocal values) according to data provided by M. Vancanneyt.
Minute 12. Minimal Standards.To facilitate the preparation of Minimal Standards for description of novel species, the subcommittee considered the preparation of a general standard applicable to all of the genera and species within the scope of the subcommittee.Special additional standards with specific requirements for genera could then be added.W. Holzapfel, together with W. Hammes, agreed to prepare a proposal for a general document including an overview table (B.Pot).B. Biavati will prepare an additional document for bifidobacteria.Within the standards, the subcommittee will include a recommendation to describe more than one strain when describing a novel species.
Minute 13.Call for new business.F. Dellaglio presented considerations concerning a new subdivision of the genus Lactobacillus.At the moment there is a great genetic diversity within this genus requiring the application of different genetic and phenotypic techniques for defining new taxonomic units.F. Dellaglio will circulate a draft within the subcommittee with recommendations for the genus Lactobacillus.

Minute 6 .
Record of attendance.The members present were: B. Biavati (Deputy Chairman), Johanna Bjo ¨rkroth, F. Dellaglio (Chairman), L. M. T. Dicks (Deputy Chairman), W.-H. Holzapfel, G. Klein (Secretary), M.-C.Montel, B. Pot and G. Reuter.Apologies for absence were received from: C. Bonaparte, W. P. Hammes, A. Kagermeier-Callaway, E. Lauer, B. Sgorbati and M. Vancanneyt.No apologies were received from M. D. Collins.G. Felis was present as a guest and K. Itoh (Tokyo, Japan) was present as an observer.Minute 7. Approval of the agenda.The proposed agenda was approved.Minute 8. Minutes of the previous meetings.The minutes of the meetings of the subcommittee in Stuttgart-Hohenheim, Germany, on 1 and 2 April 2005 were approved.
, 10 Dec 2018 22:50:49Lactosphaera and Desemzia should be included in the remit of the subcommittee.Generally, the scope of the subcommittee should be narrowed and the Secretary for Subcommittees should be contacted concerning this issue.Minute 11.Call for old business.Bifidobacterium infantis and Bifidobacterium suis belong to the species Bifidobacterium longum and consequently three new subspecies of B. longum should be proposed.B. Biavati, C. Bonaparte and B. Pot agreed to elaborate a Request for an Opinion concerning this problem.Regarding problems with the type strains within the Bifidobacterium indicum/B.coryneforme/B.asteroides-group, B. Biavati had collected the type strains from different culture collections and compared them by DNA fingerprinting.A manuscript is in preparation.
