Pseudomonas chlororaphis
Encyclopedia
Pseudomonas chlororaphis is a bacterium used as a soil inoculant
in agriculture
and horticulture
. It can act as a biocontrol
agent against certain fungal
plant pathogens via production of phenazine type antibiotic
s. Based on 16S rRNA analysis, P. chlororaphis has been placed in the P. chlororaphis group.

, P. fragi
, P. lundensis
and P. taetrolens

Soil inoculant
Soil inoculants are bacteria or fungi that are added to soils in order to improve plant growth by either:*Freeing up soil nutrients for plant use.*Entering into symbiotic relationships with plant root systems....

Antibiotic
An antibacterial is a compound or substance that kills or slows down the growth of bacteria.The term is often used synonymously with the term antibiotic; today, however, with increased knowledge of the causative agents of various infectious diseases, antibiotic has come to denote a broader range of...

The Pseudomonas chlororaphis group
P. chlororaphis lends its name to a subgroup within the genus PseudomonasPseudomonas
Pseudomonas is a genus of gammaproteobacteria, belonging to the family Pseudomonadaceae containing 191 validly described species.Recently, 16S rRNA sequence analysis has redefined the taxonomy of many bacterial species. As a result, the genus Pseudomonas includes strains formerly classified in the...
