Hygromycin B drug interactions

Treatment period. Prohibit the application of ear toxicity with drugs such as aminoglycoside, erythromycin and other antibiotics. In addition, the multi-product market to premix formulations, should be used to do hygromycin B titer units of measurement. Laboratory as a chemical reagent used. Our main research work carried out as follows, to the following specifications: 1, produced by the natural separation of bacteria, UV mutagenesis, fast processing and chemical mutagens EMS treatment, the fermentation units from 150-200U/mL to 1000-1500U/mL; and regeneration by protoplasts, spores and protoplasts with UV treatment and the optimization of fermentation medium ratio, the fermentation units in 2500-300U/mL, obtained by the strain breeding bacteria than the original starting types of 15-20 times the yield strain. 2, fermentation of, by the fermentation medium such as carbon, ammonia source, inorganic salts such as the ratio of research, especially the use of uniform design to optimize the culture medium and fermentation conditions such as temperature, pH, aeration, seed quality preferred to substantial increase in fermentation units, and identified a set of feasible fermentation process route. Amplified by the fermentation test, in which units of four batches of fermentation tank 200L average 276U/mL, up 3194U/mL, 2 吨 tank in an average of three batches 2226U/mL.
