Salinity-induced ethylene production and reactive oxygen species (ROS) inhibit agricultural productivity. The plant synthesizes directly from aminocyclopropane-1-carboxylic acid (ACC). By using ACC as a nitrogen source, bacteria with deaminase (ACCD) the overproduction of ethylene, thereby maintaining ROS. present study investigated ACCD activity previously identified rhizobacterial strains in Dworkin Foster (DF) minimal salt media supplemented 5 mM (as N-source). Bacterial isolates GKP KS2_7 (Pseudomonas aeruginosa) MBD 133 (Bacillus subtilis) could degrade into α-ketobutyrate, exhibiting producing more than ~257 nmol α-ketobutyrate mg protein−1 h−1, were evaluated for other growth-promoting (PGP) traits including indole acetic (>63 µg/mL), phosphate solubilization (>86 µg mL−1), siderophore (>20%) ammonia exopolysaccharide production. Furthermore, Fourier Transform Infrared analysis also demonstrated liberation deamination DF media, confirming activity. These showed enhanced tolerance to salinity stress 3% w/v NaCl vitro, addition facilitating multifarious PGP activities. Seed bacterization by these ACCD-producing bacterial (GKP 133) revealed significant decline stress-stimulated levels its associated growth inhibition during seedling germination. They mitigated negative effects increased root-shoot length, fresh dry weight root shoot, biomass, total sugar, protein, reducing chlorophyll content, antioxidants enzymes Pisum sativum. As result, might be applied biofertilizers counteract soil salinity.

Influence of native rhizobacteria co‐inoculation and formulation of bacterial inoculants on the growth and yield of common bean (Phaseolus vulgaris L.)

Abstract Introduction Incorporation of inoculum in different carrier materials may increase the efficacy bacterial inocula. Materials and Methods Field experiments were conducted using two strains rhizobium phosphate‐solubilizing bacteria (PSB) their respective combinations common bean‐growing regions three soil types Kenya. The field experiment was laid out a split‐plot arrangement with strain inoculations as main plot while subplots consisted (filter mud, peat moss yeast extract mannitol broth [YEMB]). Each included controls: uninoculated negative control controls that received N P fertilizer. for cropping seasons. Data collected on nodulation, shoot root biomass yield. Results Co‐inoculation bean Rhizobium phaseoli + Bacillus aryabhattai had significantly higher number nodules (55 per plant) compared to single R. inoculation (38 nodules). co‐inoculation rhizobia PSB yielded statistically at par application diammonium phosphate (18:46:0) across use filter mud material led most bacillus strains. Significantly yield obtained (1.64 Mg ha −1 ) there no significant difference between YEMB Conclusion solid material, specifically showed potential formulation inoculants. Specific ( pusense strains) Paenibacillus polymyxa B. increased growth, nodulation more efficiently than control.
