Scardovia

Abstract

Scar.do'vi.a. N.L. fem. n. Scardovia named after Vittorio Scardovi, an Italian microbiologist who has made many contributions to our knowledge of bifidobacteria. Actinobacteria / Actinobacteria / Bifidobacteriales / Bifidobacteriaceae / Scardovia Gram‐stain‐positive, non‐acid‐fast. Nonsporeforming. Nonmotile, anaerobic, rod‐shaped cells that are small and coccoid and of variable shape. Saccharoclastic. Glucose is degraded exclusively and characteristically through the fructose 6‐phosphate (F6PPK; EC 4.1.2.22) shunt (see treatment of the genus Bifidobacterium , above). The products from glucose fermentation are L ‐(+)‐lactic acid and acetic acid in the molar ratio of 1:2.9. Dextran is fermented. Found in human dental caries and plaque. DNA G + C content (mol%) : 45 ± 1 ( T m ). Type species : Scardovia inopinata (Crociani, Biavati, Alessandrini, Chiarini and Scardovi 1996) Jian and Dong 2002, 811 VP ( Bifidobacterium inopinatum Crociani, Biavati, Alessandrini, Chiarini and Scardovi 1996, 569).
