在微生物冶金体系中,浸矿环境的压力很可能超出了浸矿菌种的耐受能力,提高浸矿菌种的耐受性是一个极具挑战性的难题.氟化物对微生物的生长具有很强的抑制或杀死作用.在本文所研究的五种浸矿细菌中,A.ferrooxidans的氟耐受性是最好的,其次是A.thiooxidans,再次是L.ferriphilum与A.caldus,最差的是S.thermosulfi-dooxidans.由此看出,中度嗜热浸矿菌比常温浸矿菌更容易被氟离子抑制.

In microbial leaching systems, the microbial tolerance cannot generally bear the environmental stress. Fluoride to a large extent could inhibit the growth and activity of the microbes,or even kill the microbes. The growth state and iron/sulfur oxidation activities of five representive bioleaching microorganisms （ A. ferrooxidans ATCC 23270, L. ferriphilumYSK,S. thermosulfidooxidans ST,A. thiooxidans A01 ,A. caldus S1 ） upon different fluoride stress were compared. It showed that the fluoride tolerance of A.ferrooxidans was the best, A. thioox...
