Minute 1. Call t o order. The meeting was convened 30 June by the Chairman, G. Mocquot, in Slatter’s Hotel. Minute 2. Record of attendance. The members present were P. A. Hansen, 0. Kandler, K. Kitahara, C. W. Langston, T. Mitsuoka, G. Mocquot, G. Reuter, M. Rogosa, Elisabeth Sharpe, and P. H. A. Sneath. P. Raibaud of Jouy-en-Josas was present as an observer. Minute 3. Minutes of previous meeting. The minutes of the 1966 (Moscow) meeting were approved as read. Minute 4. Membership. J. Dehnert resigned from the Subcommittee, and R. F. Norris and N. B. Williams resigned from the Bifidus Subgroup. R. Tittsler is deceased. K. Kitahara and T. Mitsuoka were added as members of the Subcommittee, and G. H. G. Davis and W. E. C. Moore were added to the Subgroup. Minute 5 . Report on study set of strains. The Secretary reported on the findings of the members on the set of strains distributed for study. The data are to be published shortly in book form. Minute 6 . Type species of Lactobacillus. Lactobacillus helveticus was recommended to be the type species of the genus, subject t o the approval of the Judicial Commission. Minute 7. Lactobacillus buchneri. The nomenclatural type of L. buchneri was discussed. The original strain has been lost and no strain corresponding to the original has ever been isolated. The description of L. buchneri is probably based on an impure culture. ATCC 4005, a strain labeled L. buchneri and examined by the Subcommittee, does not grow at 45 C and corresponds to L. buchneri as defined by Rogosa and Sharpe (1959); it may be considered a variety of Lactobacillus brevis. Sneath suggested that L. buchneri be considered a nomen dubium. Minute 8. Lactobacillus bulgaricus. Hansen reviewed briefly the case of L. bulgaricus. The members voted in favor of applying this name to Orla-Jensen’s organism, that is the I)(-)lactic acid-producing lactobacillus, rather than to the one which forms DL-laCtiC acid, the L. bulgaricus of Rogosa et al., 1953. The type strain is ATCC 1 1842 (Thermobacterium No. 14 in the collection of Orla-Jensen). Minute 9. Lactobacillus leichmannii. The status of L. leichmannii was discussed, and the characters of ATCC 4797 were reexamined. Kitahara considers ATCC 4797 t o be a variety of L. delbrueckii, and Kandler calls it L. lactis. It was agreed that L. leichmannii is poorly described and not recognizable. Kitahara pointed out that L. leichmannii, according to the original description, should be mesophilic with a maximum of 40 to 46 C, whereas the present strain grows at 48 C. It is possible that ATCC 4797 may represent a new species. It seems that the species L. leichmannii cannot be recognized, and consequently a neotype cannot be defined. Reuter’s strain R 13, proposed as a neotype of L. leichmannii, produced DL-lactic acid according to observations by Hansen and Kandler. It grew at 15 C but not at 45 C. No further studies of the strain by the Subcommittee are contemplated. Minute 10. Lactobacillus jugurt. It was agreed to propose ATCC 521 as a neotype strain for L. jugurt. If L. jugurt is united with L. helveticus into one species, L. helveticus 15009 will typify the taxon. Minute 11. Status o f names attributed to Holland. Hansen pointed out that many of the names attributed to Holland cannot be considered as validly published because she did not attach a description or reference to a previously published description of the species. The assistance of the Judicial Commission has been requested. Sneath stated that it would not be possible to validate some of Holland’s names on the recommendation by the Subcommittee, but he suggested that they should be republished. He further stated that all types and neotypes should be published and the corrected author citation given. Minute 12. Lactobacillus fermentum. There is considerable margin for uncertainty in the description of L. fermentum. The original definition by Beijerinck is too vague t o permit
