Sinomonas flava

''Sinomonas flava'' is a species of Gram-positive, aerobic, non-motile, rod-shaped bacteria belonging to the genus ''Sinomonas''. It is notable for forming yellow-pigmented colonies, which is reflected in its species epithet "''flava''" (Latin for yellow).

Classification

• Domain: Bacteria
• Phylum: Firmicutes
• Class: Bacilli
• Order: Bacillales
• Family: Sinomonadaceae
• Genus: ''Sinomonas''
• Species: ''S. flava''

Discovery and Isolation

''Sinomonas flava'' was first described in 2011 by Huang et al. The type strain, KCTC 13076^T (= CGMCC 1.10178^T), was isolated from paddy field soil collected in Hunan Province, China.

Morphology and Characteristics

• Gram Stain: Positive

• Growth Conditions:
  • Temperature: Grows optimally at 30 °C, with a range of 15–40 °C.
  • pH: Grows optimally at pH 7.0, with a range of pH 6.0–9.0.
• Biochemical Characteristics:
  • Catalase: Positive
  • Oxidase: Negative
  • Menaquinone: Contains menaquinone-7 (MK-7) as the predominant menaquinone.
  • Fatty Acids: Major cellular fatty acids include anteiso-C_15:0 and iso-C_15:0.
• Genomic Features: The DNA G+C content of ''S. flava'' is approximately 66.8 mol%.

Habitat

''Sinomonas flava'' has been identified in soil environments, particularly paddy field soils, suggesting its role in terrestrial ecosystems.

Significance

As a relatively recently described species, the specific ecological roles and biotechnological applications of ''Sinomonas flava'' are still under investigation. However, as a common soil bacterium, it likely contributes to nutrient cycling and decomposition processes within its habitat. Its unique biochemical profile, including specific menaquinones and fatty acids, helps in its taxonomic identification and differentiation from other bacterial species.
