Cultivable bacterial densities were generally higher in soils than in roots and tended to increase in low-anthropized sites. Among the isolates, 96.15% produced ammonia, with 14 isolates showing high performance after 72 h of incubation. The concentrations produced by these bacteria ranged from 18.60 x 10^-3 to 11.05 x 10^-3 mg/ml. Three sporulating isolates were selected and identified using the API 50 CHB system as Bacillus cereus (88.6%), Bacillus coagulans (70.5%), and Brevibacillus laterosporus (83%). Ammonia assimilation increased linearly with bacterial abundance, and strain-specific efficiency differed significantly, with Brevibacillus laterosporus exhibiting the highest performance. These results highlight the potential of sporulating bacilli as promising biofertilizer candidates.]]> N’DRI Ahou Roseline, ALUI Konan Alphonse, KOKORA Aya Philomène, ANGORATCHI Marius Ebaley Yves-Magloire, ANGOUA Amanahan Mauricette Prisca, TOURE Kakoumani Lama Ruth, COULIBALY Yele Fatoumata, KARAMOKO Detto, MOROH Jean-Luc Aboya 2026-02-23 Science and Education Publishing 2026-02-23 1 14 1 8 10.12691/jaem-14-1-1 http://pubs.sciepub.com/jaem/14/1/2 Aïssatou Boiro, Ousmane Camara, Ibrahima Sory Sow, Mariama Diallo, Thierno Amadou Labé Baldé, Mamadou Ciré Diallo, Mamadou Boundoukhoura Bah, Sanaba Boumbaly, Mohamed Sahar Traoré 2026-03-02 Science and Education Publishing 2026-03-02 1 14 9 13 10.12691/jaem-14-1-2 http://pubs.sciepub.com/jaem/14/1/3 Wafaa Farouk Mohamed 2026-03-03 Science and Education Publishing 2026-03-03 1 14 14 23 10.12691/jaem-14-1-3
