摘要：
In examining the presence of indole-3-acetic acid (IAA) in supernatants of pink-pigmented facultativemethylotrophic (PPFMs) bacterial cultures, three out of the 16 isolates tested showed a positive reaction ina colorimetric assay. The presence was further unambiguously con?rmed by high-performance liquidchromatography in combination with NMR. The IAA production was signi?cantly stimulated byL-tryptophan. These results prove that PPFM bacteria are able to produce the plant hormone IAA.
