The ACC-Deaminase Producing Bacterium sp CT7.15 as a Tool for Improving Nodulation and Growth in Arid Regions of Tunisia.

is a spontaneous Mediterranean legume that can be a good candidate as pioneer plants to limit regression of vegetation cover and loss of biodiversity in Tunisian arid soils. In order to grow legumes in such soils, pairing rhizobia and nodule associated bacteria (NAB) might provide numerous advantages. In this work, cultivable biodiversity of rhizobial symbionts and NAB in nodules of plants growing in five arid regions of south Tunisia was characterized.
