説明

Several attempts were made to investigate the microbial ability to convert dissolved organic materials, which are found in appreciable concentrations in sea water, and the role it plays in the food cycle.<BR>As soon as there is polypeptone in sea water, proliferation of marine bacteria is observed and intense reducing condition of the medium is developed. The existence of marine protozoan, however, is greatly responsible for the rapid recovery from the reducing condition. Sufficient amounts of dissolved organic materials, much larger than that necessary to sustain maximum bacterial number in biological space, are favourable to make the flocs of bacteria. The growth of brine shrimp cultured in a system of protozoa and bacteria have been found to be excellent, whereas it was observed that brine shrimp could not grow well in a system of bacteria only. The organic materials gained by brine shrimp in the system of protozoa and bacteria can also be controled by the density of brine shrimps. Brine shrimp began to die in prolonged cultures, when ammonia concentration was more than 5.30 mg N in l.
