Estimation of Minimal Numbers of Azospirillum Brasilense Using Time-limited Liquid Enrichment Combined with Enzyme-linked Immunosorbent Assay
نویسندگان
چکیده
A simple time-limited liquid enrichment procedure to aid in the quantitative detection of very few cells of Azospirillum brasilense in plant roots is described. The method is based on limited multiplication of A. brasilense in convential semi-solid medium and counting of the bacteria in the enriched medium by enzyme-linked immunosorbent assay (ELISA) or by Most Probable Number (MPN) techniques. The method can be used as a complementary procedure to ELISA and MPN techniques when low numbers of A. brasilense are present in the roots.

متن کاملAzospirillum brasilense produces the auxin-like phenylacetic acid by using the key enzyme for indole-3-acetic acid biosynthesis.
An antimicrobial compound was isolated from Azospirillum brasilense culture extracts by high-performance liquid chromatography and further identified by gas chromatography-mass spectrometry as the auxin-like molecule, phenylacetic acid (PAA). PAA synthesis was found to be mediated by the indole-3-pyruvate decarboxylase, previously identified as a key enzyme in indole-3-acetic acid (IAA) product...
