Key Points

Evaluate the infectivity and stability of bacteriophage ΦNF-1 for biological nitrification control in agriculture.
Assessed phage survival in aqueous suspensions across various temperatures and pH levels.
Conducted field trials in agricultural soils to measure phage infectivity over six months.
Utilized a calcium carbonate-based photoprotectant to enhance phage stability under UV exposure.
ΦNF-1 remained infectious for over six months at temperatures of 4-20 °C and neutral to alkaline pH.
Infectivity persisted in agricultural soils for six months, with lower recovery in sandy soils.
The photoprotectant significantly improved phage survival under sunlight exposure.

Abstract

, expanding its known host range. ΦNF-1 remained infectious for over six months in aqueous suspensions at 4-20 °C and neutral to alkaline pH, but declined rapidly under acidic conditions. In agricultural soils, infectivity persisted for up to six months, though recovery was lower in sandy soils. A calcium carbonate-based photoprotectant significantly enhanced phage survival under UV and sunlight exposure. Overall, ΦNF-1 shows strong potential as a stable, host-specific biological nitrification inhibitor to improve nitrogen use efficiency and reduce environmental impacts of fertilization.
