Effect of a residue after evaporation from industrial vitamin C fermentation on chemical and microbial properties of alkali-saline soil

ABSTRACT

Residue after evaporation [RAE] from industrial vitamin C fermentation is emitted as a waste product at an amount of 60,000 tons per year in China. The disposal of RAE is difficult because of its high chemical oxygen demand [1.17[x]10[6] mg/1] and low pH [0.27]
