[Simple method of isolation and study of anaerobic bacteria].

The description is given of a simple procedure for the surface culture of anaerobic bacteria in Petri dishes, using for anaerobiosis pieces of cardboard imbibed in pyrogalic acid and potassium carbonate solution respectively, pressing the seeded medium in the Petri dish, which becomes air-tight. The efficiency of the procedure was confirmed by seeding Clostridium strains, different collection species, and by isolation and identification of sulfite-reducing strains from meat and meat products.
