摘　　要：从长沙金井制革厂的废水中分离得到抗三价铬细菌12株,真菌15株,耐铬试验发现菌株:B2、B5、F2和P1的耐铬能力强,去铬试验表明真菌B5去三价铬率最高,达50%。形态鉴定和ITS(内转录间隔区)序列分析表明,菌株B5为微紫青霉菌。研究结果为三价铬的微生物治理提供了新的优势菌种。12 bacteria strains and 15 fungi strains which can resist the Cr3＋ were isolated from Changsha jinjing tannery wastewater. It shows that the strain B2, Bs,F2 and P1 have a strong resistance to Cr3 ＋. It also shows that the B5 is an efficient fungus for removal of Cr3＋ with a removal rate of 50%. B5 strain is determined to be Penicillium janthinellum by morphological identification and ITS（internal transcribed spacer） sequence analysis. This study provides a new strains for the microbial treatment of Cr3＋.
