Title: Isolation and identification of Azospirillium zeae from Acacia tortilis at Riyadh, Saudi Arabia


The Study was conducted at Riyadh, Saudi Arabia to Isolate and Identify the Azospirillium zeae from Acacia tortilis. Useful bacteria associated with the plant roots have the potential to alleviate the burden of using costly and harmful agrochemicals in harsh environments. Finding of novel and appropriate bacteria for enhancing plant growth is among the main primary challenges involved in achieving the agronomic application of plant beneficial bacteria. A bacterium isolated from the rhizospheric soil of the legume Acacia tortilis was described based on several biochemical, morphological and molecular analyses. The bacterium H1P is motile, negative in biotin medium, no growth in 3% NaCl, negative D-Ribose, positive D- glucose. Identification of the isolate via 16s rDNA via the BLASTn revealed that the isolate is an Azospirillum species with a 96.9% similarity to Azospirillum zeae H1P. Phylogenetic analyses with MEGA6 software showed that the isolate shares an ancestor with Azospirillum zeae, eventually branching off into a separate taxon. Azospirillum zeae isolated from Acacia tortilis it is considered first report.

Audience Take Away Notes:

  • Free nitrogen Azospirillum bacteria isolated for the  first time from the Acacia rhizosphere in the arid area, these advantages can be used to increase agricultural production under global climate change.
  • One of valuable economic trees gum Arabic tree developed and increased their gum product  
  • This research can be use as bioferilizer  to improve plant production and soil fertility


Kamal Hassan S. Elmakki studied Soil and Water Sciences at the Kordofan University, Sudan and graduated as B.Sc 2004 and M. Sc 2008 at the same institution. Then I joined as the lecturer in the department of soil and water sciences, faculty of NRES, University of Kordofan, Sudan.  I received my PhD degree in 2018 in Soil Sciences (Soil Microbiology), Faculty of Food and Agricultural Sciences, University of King Saud University, Saudi Arabia. Now I am assistant professor at University of Kordofan, Soil and Water Sciences, Faculty of NRES, I published 7 research articles.
