Species

Dyadobacter fermentans

The Dyadobacter Genus currently consists of 14 recognized species. They have been isolated from various enviroments such as freshwater, seawater, glaciers, desert sand, plants, soils, and animals.

Description and Significance

Dyadobacter fermentans is a Biosafety level 1 organism. It is aerobic, heterotrophic, and non-motile. It produces a pigment similar to flexirubin.

It can survive in nitrogen limited conditions by competing with the host plant for resources.

Isolated and discovered in 1998, Dyadobacter fermentans is an aerobic, gram-negative, non-motile, rod shaped chemoorganotroph. The rods can appear as pairs or in chains. D. fermentans is found in many plants, the cysts of nematodes (Heterodera glycines), and in contaminated soil. This strain can also be isolated from the stem of maize plants when watered with fertilizer containing no nitrogen. The term “fermentans” is derived from the bacterium's ability to ferment glucose and fructose.

D. fermentans can decrease N2O emissions in soil, allowing it to be utilized as a bacterial form of denitrification in the rhizosphere. This ability has potential for various environmental applications, which could mitigate greenhouse gasses from agricultural fields.

Ecology and Pathogenesis

Maize (Zea Mays) is host to Dyadobacter fermentans. D. fermentans is not thought to be either beneficial or pathogenic to Maize. The presence or lack of D. fermentans has no significant influence over Maize yield.
