Overview

Randomized trial shows improved bacterial viability in hydrogels for crop productivity, suggesting effective use in agriculture.

Key Points

  • Investigate the encapsulation of Azospirillum sp. strains in amidated pectin hydrogels for enhanced bacterial survival and soil release.
  • Tested three strains of Azospirillum in 1-3% amidated pectin hydrogels
  • Assessed encapsulated bacterial populations (CFU/g) after drying
  • Evaluated bacterial release and viability over 60 days.
  • AbV5: 7.8 × 10⁷ CFU/g, HM053: 6.3 × 10⁷ CFU/g, Az39: 2.5 × 10⁹ CFU/g post-encapsulation
  • Az39 maintained initial population for 15 days, while AbV5 and HM053 showed no significant reduction after 45 and 60 days
  • Biodegradable beads lost over 94% mass in soil within 15 days.
