The team of LI Dong isolated two cocci, Paracoccus denitrificans Y5 and Habitatella paracoccus versutus D6 which could grow heterotrophically on glucose and ammonia and autotrophically on biogas slurry (CO2 as inorganic carbon source and ammonia nitrogen) under conditions of providing reducing power. The protein contents of strains Y5 and D6 was 67 – 74 % of dry weight, much higher than the protein content of soybean, and amino acid composition resembled that of soybeans.
