从土壤中筛选出一株适合用甘蔗糖蜜酒精发酵液生产腐植酸的菌株H812。实验结果表明,该菌株培养的最适酒精发酵液浓度为16°Bx,最适宜培养条件为:时间8天、温度34℃、摇床转速200 r/m i n、初始p H 7.0、接种量12%和装液量 A strain H812 suitable for producing humic acid from sugarcane molasses alcoholic fermentation broth was screened from soil. The experimental results showed that the optimum fermentation broth of this strain was 16 ° Bx. The optimum culture conditions were as follows: time 8 days, temperature 34 ℃, shaking speed 200 r / min, initial pH 7, inoculum 12% And liquid loading
