Abstract

A study was conducted to observe the resistance of native isolated bacteria towards selected heavy metals (iron; Fe and manganese; Mn) in a separate exposure. Isolated bacteria were evaluated by culturing them in nutrient broth medium that contained approximately 3 ×10 CFU/mL bacteria with different initial concentrations (0, 50, 100 and 200 mg/L). Result showed that a plate with bacterial growth indicated bacterial resistance, which was verified based on CFU/mL. At 0 mg/L, bacteria grew well on the plate with Fe and Mn. The bacterial number began to decrease at 50 and 100 mg/L for Fe and at 200 mg/L for Mn. Only a few colonies survived (isolate AM2) the toxicity of high Fe amount; the isolated bacteria almost showed no growth along the plate. AM2, AM3 and AM4 presented resistance to Mn until 200 mg/L, but not AM6. The bacteria showed no growth at 100 and 200 mg/L. Thus, the Fe and Mn concentrations that can be applied during acclimatisation ranged from 0 mg/L to 200 mg/L with isolated AM2 and AM4 for Fe and Mn removal.

活性污泥中分离的原生细菌对铁和锰的抗性

研究了天然分离细菌对重金属(铁;铁和锰;Mn)在单独的曝光。分离的细菌通过在含有约3个×10 CFU/mL细菌的营养肉汤培养基中培养来评估，这些细菌具有不同的初始浓度(0、50、100和200 mg/L)。结果显示，有细菌生长的平板显示细菌耐药，以CFU/mL为单位进行验证。当浓度为0 mg/L时，细菌在含铁和锰的培养皿上生长良好。当铁浓度为50和100 mg/L，锰浓度为200 mg/L时，细菌数量开始减少。在高铁量的毒性作用下，只有少数菌落存活(分离AM2);分离出来的细菌几乎没有沿着平板生长。AM2、AM3和AM4对Mn的抗性持续到200 mg/L，而AM6则没有。在100和200 mg/L的浓度下，细菌没有生长。因此，在驯化过程中，可施用的铁和锰浓度范围为0 mg/L至200 mg/L，并分离AM2和AM4去除铁和锰。
