不同碳、氮源对苯酚降解菌菌XH-10的生长和苯酚降解的影响

Different Carbons and Nitrogen Sources Effects of on the Growth and Phenol Degradation of the Ttrain XH-10

实验探测了18种碳、氮源对高效苯酚降解菌XH-10生长和苯酚降解的影响.将实验组与对照组进行比较,实验表明:(1)乳糖、麦芽糖、淀粉、蛋白胨、酵母粉对XH-10菌体生长具有强烈的促进作用,非常适宜XH-10生长;葡萄糖、羧甲基纤维素钠、氯化铵、乙酸铵、草酸铵、硝酸铵、尿素对XH-10菌体生长具有一定的促进作用,比较适宜XH-10生长;蔗糖、甘油、硝酸钠对XH-10菌体生长具有较低的促进作用,基本适宜XH-10生长;乙酸钠、磷酸铵、氯化铵对XH-10菌体生长具有明显的抑制作用,不适宜XH-10生长,但乙酸钠、氯化铵在较低浓度范围内,XH-10仍有一定的生长潜力.(2)乳糖、麦芽糖、淀粉对XH-10苯酚降解几乎没有影响,非常适宜XH-10苯酚降解;葡萄糖、羧甲基纤维素钠对XH-10苯酚降解有较小的抑制作用,比较适宜XH-10苯酚降解;蔗糖、甘油、蛋白胨、酵母粉、硝酸铵、尿素对XH-10苯酚降解有一定的抑制作用,基本适宜XH-10苯酚降解;乙酸钠、氯化铵、乙酸铵、硝酸钠、磷酸铵、氯化铵、草酸铵对XH-10苯酚降解有明显的抑制作用,不适宜XH-10苯酚降解,但乙酸铵、草酸铵在较低浓度范围内,XH-10仍有一定的苯酚降解潜力.本研究成果为菌株XH-10的营养生理研究奠定基础,同时为其含酚废水的处理工艺提供依据.

This study detected 18 types of carbons and nitrogen sources for efficient phenol-degrading bacteria XH - 10 growth and phenol degradation. The experimental group and control group were compared and the results showed that;the lactose, maltose, starch, peptone, yeast powder had strong promoting effect on XH - 10 cell growth, very suitable for the growth of XH - 10 ; glucose, sodium carboxymethyl cellulose, ammonium chloride, ammonium acetate, ammonium oxalate, ammonium nitrate, urea had certain stimulative effect on XH - 10 cell growth, suitable for the growth of XH - 10 ; sucrose, glycerin, sodium nitrate had lower stimulative effect on XH - 10 cell growth, roughly suitable of XH- 10 growth; sodium acetate, ammonium phosphate, ammonium chloride had obvious negative effect on XH - 10 cell growth, not suitable for XH - 10 growth, phenol degradation Secood the lactose, maltose, starch had no influence on the XH -10, very suitable for XH -10 phenol degradation; glucose, sodium car- boxymethyl cellulose had a little hegative effeit on XH - 10 phenol degradation for, suitable for XH - 10 phenol degradation ; glycerol, sucrose, peptone, yeast powder, ammonium nitrate, urea had some negative effect,roughly suitable of XH -10 phenol degradation; sodium acetate, ammonium chloride, ammonium acetate, sodium nitrate, ammonium phosphate, ammonium chloride, ammonium oxalate were not suitable for XH - 10 degradation of phenol.
