Abstract:
In order to utilize protein-rich bio-wastes from the process of lincomycin manufacturing,mesophilic anaerobic digestion experiments were conducted in a batch mode to evaluate the inhibitory effects of ammonia concentrations(300—4500 mg·L-1)and lincomycin ones(0—100 mg·L-1)on methane production by anaerobic digestion of the bio-wastes.The results show that both the concentrations of ammonia and lincomycin had significant negative correlations with the cumulated amount of methane.After 240 h of batch incubation, the 50% effective inhibitory concentrations(EC50)were 1445 mg·L-1 and 35 mg·L-1 for ammonia and lincomycin respectively, and 27—28 mg·L-1 for free ammonia.Furthermore, there existed lincomycin in the system at concentration of 25 mg·L-1, the inhibitory trend and level of ammonia on anaerobic digestion were the same as that without lincomycin.Therefore, the inhibition of ammonia on anaerobic digestion is independent of lincomycin.

摘要:
以含高蛋白质和抗生素的林可霉素生产残渣产沼利用为背景,通过中温厌氧消化批式实验,研究不同的氨氮浓度(300~4500 mg·L-1)和林可霉素浓度(0~100 mg·L-1)对含氮含抗生素类生物质废物的厌氧消化产甲烷能力的抑制作用。结果表明,氨氮和林可霉素浓度均与累积产甲烷量显著负相关。经过240 h的培养,氨氮和林可霉素对厌氧消化产甲烷量的半抑制浓度(EC50)分别为1445 mg·L-1和35 mg·L-1;游离氨的EC50在27~28 mg·L-1之间。在25 mg·L-1林可霉素存在下,氨氮对
