METHOD FOR STORING AND SHIPPING LIVING MICROORGANISMS PROVIDING FOOD FOR FISH Russian patent published in 1998 - IPC

FIELD: commercial fish farming; methods for preparing aqueous media for shipping and storing microorganisms used as food for fish. SUBSTANCE: aqueous medium is subjected to aeration, while simultaneously adding to it solution having the following composition: kanamycin sulfate, 0.001-1.0 g/l; nystatin (mycostatin), 1000-1,000,000 units/l; or benzylpenicillin, 0.001-1.0 g/l; sulphalene, 1000-1,000,000 units/l. Solution must meet the following requirements: pH = 4.5-8.5; concentration of heavy metal salts, 0.005 mg/l; Zn, ≤ 0.005 mg/l; Cu, ≤ 0.005 mg/l; Cr, ≤ 0.01 mg/l; Ni, ≤ 0.01 mg/l; electroconductivity, 300-350 mcS. EFFECT: improved vital activity of microorganisms providing food for fish. 3 cl
