Utilization of lysed and dried bacterial biomass from the marine purple photosynthetic bacterium *Rhodovulum sulfidophilum* as a sustainable nitrogen fertilizer for plant production

S. R. Morey-yagi, Y. Kinoshita, et al.

This groundbreaking study reveals the potential of lysed and dried bacterial biomass from *Rhodovulum sulfidophilum* as a sustainable nitrogen fertilizer, showing remarkable results in plant germination and growth. Conducted by a team of experts from Kyoto University and Symbiobe Inc., the research highlights an innovative approach to optimizing nitrogen application in agriculture.

Abstract
This study explores the use of lysed and dried bacterial biomass from *Rhodovulum sulfidophilum* as a sustainable nitrogen fertilizer. The biomass, containing approximately 11% nitrogen, showed no negative effects on plant germination and growth at application rates up to four times that of a conventional mineral fertilizer. While requiring roughly twice the application rate of the mineral fertilizer for comparable plant growth, this is attributed to the 62% mineralization rate of bacterial nitrogen. The research demonstrates the potential of *R. sulfidophilum* as a viable nitrogen fertilizer source.
