摘要：

In examining the presence of indole-3-acetic acid (IAA) in supernatants of pink-pigmented facultative methylotrophic (PPFMs) bacterial cultures, three out of the 16 isolates tested showed a positive reaction in a colorimetric assay. The presence was further unambiguously confirmed by high-performance liquid chromatography in combination with NMR. The IAA production was significantly stimulated by L-tryptophan. These results prove that PPFM bacteria are able to produce the plant hormone IAA.
