The invention discloses a Geomonas niftrogeniifigens RF4 and its application. It belongs to the field of microbial technology. Geomonas RF4 is strictly anaerobic, gram-negative, motile, and flagellar all over the body. Colonies are red and round. Contactase and oxidase reactions were negative. Strain RF4 has the ability to produce alkaline phosphatase, acid phosphatase and naphthol-AS-BI-phosphohydrolase. For the first time, Geomonas was found to have both iron-reducing and nitrogen-fixing functions. It has good application prospects in agricultural production to drive rice growth, reduce nitrogen fertilizer application, and reduce environmental pollution. |
