| Abstract | The objectives of this research were to isolate plant growth promoting rhizobacteria that can produce extracellular vitamin B-6 from rhizospheric soil of legume plants in Khon Kaen University and test their plant growth promoting properties. A total of 932 isolates were pick up by using extracellular vitamin B-6 producing property. Then, 50 isolates were selected to study plant growth promoting properties such as phosphate solubilization, potassium solubilization and Indole-3-acetic acid (IAA) production. Forty-eight isolates showed phosphate solubilizing property; forty-five isolates could solubilize insoluble potassium; and all 50 isolates showed IAA production. Then, the amount of vitamin B-6 production was examined every 6 hours until the end of 24 hours. Five isolates had the highest amount of produced vitamin B-6 at 6 hours and then were identified by biochemical test. Among them, three isolates were related to Brevibacillus laterosporus, Acinetobacter baumannii complex, Bacillus thuringiensis, and two isolates were related to Bacillus cereus. All 5 isolates were in plant growth promoting group. Previous report showed Ba. cereus could produce vitamin B-6, but there are no reports on the production of vitamin B-6 by Ba. thuringiensis, B. laterosporus and A. baumannii complex. However, further studies are needed to obtain their utility to promote plant growth. |
