Abstract/OtherAbstract:
The distribution and diversity of acyl homoserine lactone (AHL) producing bacteria in black, brown, red, and meadow soils were investigated using culture-dependent method. One out of seventy six and five out of fifty isolates from the black and the brown soil were AHL-biosensor active, respectively. They were affiliated to the genera Ensifer and Pseudomonas and the family Enterobacteriaceae. Thin layer chromatography showed that the most of them produced AHLs with acyl side chain of 6 or 8 carbons. No AHL-producer was found in red and meadow soils. A potential novel AHL-based quorum sensing and quenching system was identified by sequencing in the black soil isolate Ensifer adhaerens X097 that harbored two AHL synthetase-like proteins and one amidohydrolase-like protein. This is the first report of comparison of AHL-producers among different soils. Our data showed that composition of AHL-producers were niche specific and were not in proportion with community population.
