[New genus of budding bacteria Angulomicrobium tetraedrale having radially symmetrical cells]. / Novyi rod pochkuiushchikhsia bakterii Angulomicrobium tetraedrale s radial'noi simmetriei kletki.

The growth cycle and the ultrathin structure were compared in two strains of polygonal bacteria. Due to the presence of radial symmetry, the type of division, the character of metabolism and physiology in common, the polygonal bacteria are classed as a separate genus, Angulomicrobium nov. gen. It would be too early to divide the genus into species. The diagnosis of the new genus and the species A. tetraedrale nov. gen. nov. sp. is presented.

[A new triangular bacterium]. / Novye treugol'nye bakterii

A new bacterium has been isolated; its cells are of a triangle shape and have a radial symmetry. The organism was compared with two other bacteria of a triangle shape described earlier: it differs from them by morphology and physiology.
