“…Since then there are limited reports describing strains of Paenibacillus as PGPR. Strains of Paenibacillus have not received comparable importance as efficient PGPR as strains of Acinetobacter, Agrobacterium, Arthobacter, Azotobacter, Sinorhizobium, Azospirillum, Burkholderia, Bradyrhizobium, Rhizobium, Frankia, Serratia, Thiobacillus, Pseudomonads, and Bacillus have received (Jacobson, Pasternak, & Glick, 1994;Sunar, Dey, Chakraborty, & Chakraborty, 2013;Vessey, 2003). However, over the period of last 10 years, few strains of Paenibacillus were rediscovered as nitrogen fixers which helped them to prove superiority over other extensively studied PGPR.…”
