- Observation Thirty-nine IAA-producing strains were isolated from the rhizosphere of Alsophila spinulosa.
- Observation The highest IAA-producing strain, R74, was identified as Burkholderia pyrrocinia by morphological and molecular analyses.
- Observation The optimal inoculum age of strain R74 for IAA production was 12-20 h.
- Observation The optimal incubation time for IAA production was 24 h.
- Observation The optimal culture temperature for IAA production was 32 °C.
- Observation The optimal pH for IAA production was 7.0.
- Observation The genome of strain R74 is 8,347,169 bp in size.
- Observation The genome of strain R74 has a GC content of 67%.
