Abstract

Photosynthetic bacteria (PSB) are microbial groups with high application potential in animal husbandry due to their robust growth, adaptability to artificial conditions, and rich nutritional composition. This study aimed to isolate and select indigenous PSB strains from the coastal areas of Hue city for the development of protein-rich microbial biomass as a supplementary feed source for livestock. From a total of 30 collected samples of coastal sediment and water, 28 PSB strains were successfully isolated. These strains were evaluated for their growth performance under laboratory conditions and key nutritional characteristics. Among them, four strains—ĐH1.2, RC2.2, TH1.4, and LA2.6—demonstrated outstanding growth and notable nutritional profiles, with total protein contents ranging from 36.25% to 50.75%, lipid contents from 9.4% to 11.0%, and carotenoid concentrations from 1.54 to 2.14 mg/mL. These selected strains show strong potential as foundational candidates for further research on the development of localized PSB biomass for sustainable animal feed production.
