Abstract Nitrogen is a crucial element for plant growth, driving vibrant greenery, photosynthesis, and overall vitality. This research focused on isolating, characterizing, identifying nitrogen-fixing bacteria from the rhizosphere of Sonneratia apetala in Sundarbans, Khulna, Bangladesh, with goal assessing their potential as biofertilizers. Despite Sundarbans’ rich microbial diversity, less than 5–10% species have been identified due to challenges culturing, which has limited exploration applications. In this study, were isolated using nitrogen-free media, including yeast extract mannitol agar(YEMA) Burks followed by an ammonification test select ammonia-producing bacteria. process yielded ten bacterial isolates capable producing indole-3-acetic acid (IAA). Various biochemical tests, oxidase, catalase, methyl red, indole, urease, citrate, triple sugar iron, starch hydrolysis, conducted. The isolates, designated AK1 AK10, Rossellomorea sp., Clostridium Achromobacter Pseudomonas Gluconacetobacter Scytonema Nesterenkonia Bacillus respectively. Additionally, AK1, AK3, AK4, AK10 confirmed through 16S rRNA sequencing. A pot further revealed that isolate AK-1 significantly stimulated growth development maize seedlings. Future studies are needed examine impact these crop yield seed quality, better determine suitability

The adoption of “consortium” potential microorganisms can optimize the forest seedling production process. objective this study was to evaluate in greenhouse conditions effect co-inoculation between Trichoderma harzianum, Bradyrhizobium diazoefficiens, and B. elkanni on growth Schizolobium parahyba var. (Vell.) Blake seedlings. treatments consisted fungi strains (T. harzianum ESALQ 1306); bacteria (B. (SEMIA 5080) + diazoefficiens 587)); consortium (Trichoderma +Bradyrhizobium), a control treatment. seeds were sown, evaluations carried out 120 days after sowing. variables analyzed shoot height (SH), stem diameter (SD), root length (RL), fresh mass (SFM), (RFM), total biomass (TFM), dry (SDM), (BIO), Dickson quality index (DQI). evaluated proved be effective S. parahyba, with emphasis for parameters, promoting an increase SH (23%), SD (36%), RL (84%). For mass, non-inoculated seedlings (control) obtained decrease 67% (TFM) 83% (BIO) compared co-inoculation. results indicate promising method production; biostimulators allowed plant development, which led success morphometric indices. mechanisms involved microorganisms’ native wood species allow their large scale silvicultural sector are still scarce, new research is needed elucidate physiological biochemical involved.
