ABSTRACT
BACKGROUND:
There is a large amount of industrial wastewater produced by the mushroom industry during the canning processing each year, which could provide abundant carbon, nitrogen and inorganic salts for microbial growth. The aim of this study was to optimize the culture conditions for Bacillus licheniformis cultured in the Agaricus bisporus industrial wastewater to produce the agricultural microbial fertilizer.RESULTS:
In this work, the maximal biomass of B. licheniformis could be obtained under the following culture conditions 33.7°C, pH 7.0, 221 rpm shaking speed, 0.5% wastewater, 2 (vv, %) inoculum dose, loading liquid of 60 mL/250 mL and a culture time of 24 h, and the average experimental value obtained was 1.35 ± 0.04 × 109 Obj/mL, which was within the 95% confidence interval of the predicted model (1.291.38 × 109 Obj/mL), and met the national microbial fertilizers' standard in China. Furthermore, the field experiment results showed that the fermentation broth of B. licheniformis could significantly improve the yield of Anoectochilus roxburghii.CONCLUSIONS:
Agaricus bisporus industrial wastewater can be used to produce agricultural microbial fertilizer.
