ProjectsMicroorganisms that tolerate high concentrations of ammonia in anaerobic digestion (AD) are slow-growing and easily washed out in continuous digesters with suspended bacterial systems. The development of ammonia tolerant microorganism living in biofilms is proposed as a solution. In the project the potential role of ammonia tolerant cultures will be analyzed.
