“…Growth of BMG 804 T in the presence of 0-10 % NaCl (w/v) was determined on yeast extract-malt extract medium (ISP 2). Additionally, production of indole, nitrate reduction and hydrolysis of tyrosine (Gordon & Smith, 1955), casein, starch, xanthine, hypoxanthine (Montero-Calasanz et al, 2012), gelatin (Clarke, 1953) and aesculin (Swan, 1954) were tested.…”

A novel Gram-stain-negative, aerobic, heterotrophic, stalked and capsulated bacterium with potential denitrification ability, designated strain TAR-002 T , was isolated from deep seafloor sediment in Japan. Colonies lacked lustre, and were viscous and translucent white. The ranges of temperature, pH and salt concentration for growth were 8-30 6C, pH 6.0-10.0 and 1-3 % (w/v) NaCl. Phylogenetic analysis based on 16S rRNA gene sequences confirmed that strain TAR-002 T belongs to the genus Brevundimonas of the class Alphaproteobacteria. Levels of similarity between the 16S rRNA gene sequence of strain TAR-002 T and those of the type strains of species of the genus Brevundimonas were 93.5-98.9 %; the most closely related species was Brevundimonas basaltis. In DNA-DNA hybridization assays between strain TAR-002 T and its phylogenetic neighbours, Brevundimonas lenta DS-18 T , B. basaltis J22 T , Brevundimonas subvibrioides ATCC 15264 T and Brevundimonas alba DSM 4736 T , mean hybridization levels were 6.4-27.7 %. The G+C content of strain TAR-002 T was 70.3 mol%. Q-10 was the major respiratory isoprenoid quinone. The major fatty acids were C 18 : 1 v7c and C 16 : 0 , and the presence of 1,indicates the affiliation of strain TAR-002 T with the genus Brevundimonas. On the basis of biological characteristics and 16S rRNA gene sequence comparisons, strain TAR-002 T is considered to represent a novel species of the genus Brevundimonas, for which the name Brevundimonas denitrificans sp. nov. is proposed; the type strain is TAR-002 T (5NBRC 110107 T 5CECT 8537 T ).

“…Foley & Wheeler (1945) examined four-strains of group D Streptococcus of different serological types ; they reported that in three strains the group specific antigen was probably protein and in the fourth strain probably carbohydrate. That the group D antigen is different in nature from the A, B, and C group antigens is also suggested by the work of Maxted (1948) and Swan (1954), who reported that the group antigen of group D streptococci was not as easily released by the action of a streptomyces enzyme as was the group antigen of group A, B and C streptococci. Technical difficulties not generally met in other groups of Streptococcus are often encountered in preparing potent group D antisera and in the extraction of the group antigen for serological identification of isolates (Shattock, 1949 Perry, Wilson, Newland & Briggs, 1955).…”

SUMMARYGel-diffusion precipitin tests showed that the Streptococcus group D antigen, as usually demonstrated by ring-precipitin tests, was serologically identical in all four species (Streptococcus faecalis, S . faecium, S . durans, S . bovis). Cell walls of representative cultures of all group D species had a similar chemical composition (determined by chromatograpy) as found by other workers. The one strain of S. bovis examined lacked galactosamine which was present in the cell walls of the other group D species. The group D specific antigen was found in the residue (cell contents) after the cell-wall fraction had been removed, unlike the group A specific antigen which forms an integral part of the cell wall.
