Summary It was established that anAlnus glutinosa isolate (LDAgp 1) is able to utilize mono- and disaccharides and shows a limited growth ability on arabinose and starch. This contrasts with an isolate fromAlnus viridis (AvcI 1) andComptonia peregrina (CpI1), which apparently lack glycolytic pathway activity. These latter isolates can utilize some tricarboxylic acids in contrast to LDAgp1. Volatile fatty acids or their salts, such as propionic acid and acetate, were utilized by all three isolates. Besides a general ability to utilize inorganic nitrogen sources, some amino acids and urea, selected isolates showed a limitedability to utilize adenine and uracil. A simple, synthetic medium based on propionic acid as the energy source was developed. On this medium some isolates showed growth stimulation in the presence of biotin. The metabolic aspects of the utilization of carbon and nitrogen sources, as well as some ecological consequences are discussed.
