In this study, the potential of selected psychrotolerant yeast strains for phenol biodegradation was studied. From 39 strains isolated from soil and water samples from Rucianka peat bog, three psychrotolerant yeast strains, A01, B02, and L01, showed the ability to degrade phenol. The result shows that all three yeast strains could degrade phenol at 500 and 750 mg l concentration, whereas strains A01 and L01 could degrade phenol at 1000 mg l concentration. The time needed for degradation of each phenol concentration was no longer than 2 days. Strains A01, B02, and L01 were identified based on 26S rDNA and ITS sequence analysis as belonging to species , , and , respectively.
在本研究中,对所选耐冷酵母菌株进行苯酚生物降解的潜力进行了研究。从鲁恰恩卡泥炭沼泽的土壤和水样中分离出的39株菌株中,三株耐冷酵母菌株A01、B02和L01表现出降解苯酚的能力。结果表明,所有三株酵母菌株都能在500和750毫克/升浓度下降解苯酚,而菌株A01和L01能在1000毫克/升浓度下降解苯酚。降解每种苯酚浓度所需的时间不超过2天。基于26S rDNA和ITS序列分析,菌株A01、B02和L01分别被鉴定为属于 、 和 物种。
