Effect of <i>Bacillus</i> spp. strains on wheat nutrient assimilation and bioformulation by new spray drying approach using natural phosphate powder
Bibliographic record
Abstract
The present work is aiming to propose a new formulation of Bacillus spp. strains in combination with natural phosphate by spray drying. Bacillus sp. strain (SS0306) has proven its plant growth promoting effectiveness mainly on phosphate solubilization capacity and improved nutrient assimilation in wheat plants. Bacterial microencapsulation methods involved spray-drying assays that were conducted using 5% of rock phosphate with 2%–10% of maltodextrin and 2% of alginic acid sodium salt. The process parameters were also optimized with inlet temperature (155 °C), feed rate (9 min mL−1), and spray air rate (413.87 L h−1). Results showed a moisture content of the dried powders ranged between 2% and 8% and satisfactory viability levels of Bacillus sp. SS0306 (105–106 CFU g−1) after drying assay, with the survival rates between 61.56% and 64.18%. Optimized process reached 50.30% and 65.10% for the product yield, with 1.25 ± 0.006 mg g−1 of higher Pi content observed in rock phosphate formulations based on Alg 2%. The present study opens new possibilities to develop Bio-mineral fertilizers using the spray drying approach.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
