Miniphocaeibacter halophilus sp. nov., an ammonium-tolerant acetate-producing bacterium isolated from a biogas system.

ABSTRACT: An anaerobic bacterial strain, designated AMB_01^T, recovered from mesophilic propionate enrichment of a high-ammonia biogas digester, was characterised using phenotypic and molecular taxonomic methods. Cells of AMB_01^T are coccus-shaped and often occur arranged as diplococci or sarcina. Growth occurred at 20-45 °C, initial pH 5.5-8.5 and with up to 0.7 M NH₄Cl, with optimum growth at 37-42 °C and pH 8.0. AMB_01^T achieved high cell density and highest acetate production when grown on carbohydrates, including monomers, disaccharides and polysaccharides, such as glucose, maltose, cellobiose and starch. The strain was also able to use amino acids and some organic acids and alcoholic compounds for growth. Acetate was formed as the main product and yea
