摘要: 为了获得高效的细菌菌剂,采用单因素试验对萎缩芽孢杆菌XT1-4的液体发酵条件进行优化,研究结果表明:该菌株的最佳培养条件为:发酵温度32℃、初始p H值7.0、装液量50 m L/250 m L三角瓶、接种量2%、培养时间24 h。研究结果为工业生产萎缩芽孢杆菌菌剂提供了基础数据。
Abstract: To obtain high density bacterial fertilizer, the liquid fermentation conditions of Bacillus atrophaeus were optimized by single factor experiments. The results showed that the optimal culture conditions were temperature of 32℃, initial p H of7.0, medium volume of 50 m L/250 m L flask, inoculation amount of 2% and incubation time of 24 h. The results could provide basic data for production of Bacillus atrophaeus bacterial fertilizer for agricultural application.
