Role of Acetic Acid Bacteria in Sustainable Agriculture
Selvaraj, Anandakumar & Muniyappan, Umapathi. (2021). Role of Acetic Acid Bacteria in Sustainable Agriculture. Agriculture & Food: E-Newsletter. 3. 414-416.
Excerpts:
“Some of the important and well known PGPB such as Rhizobium, Azospirillum, Azotobacter, Sinorhizobium, Gluconacetobacter, Bacillus, Pseudomonas, Burkholderia,Frankia, Azoarcus, Herbaspirillum, and Serratia are utilized in the agricultural system for sustainable crop production. Moreover, acetic acid bacteria (AAB) is one among them reported to enhance plant growth and health through imparting different plant growth promoting mechanisms, including nitrogen fixation, phytohormones production, mineral nutrients solubilization, exhibiting antagonistic effect against pathogens, etc.”
“This AAB are associated with diverse plant species, colonizing the inner tissues and roots to promote plant growth through direct or indirect mechanisms besides N2 fixation, including synthesis of phytohormones, solubilization of nutrients, and antagonistic effects against phytopathogens (Table 1). Moreover, AAB is also found in the rhizosphere of many plants and establishes a more specific association with plants tissues as an endophyte.”
“[Nitrogen fixation] is exclusive to Bacteria and Archaea, and the microorganisms that fix nitrogen are named diazotrophs. AAB belongs to the genera Gluconacetobacter, Acetobacter and Swaminathania are able to fix atmospheric N2”
“Mineral phosphate solubilization is generally considered to be a plant growth promoting characteristic for PGPB. This activity has been observed in different strains of G. diazotrophicus and S. salitolerans.”
