摘　　要：生物脱硫具有低成本、可脱有机硫等优点,不足之处是菌种生长不稳定,需要不断进行驯化培养以提高菌种的脱硫活性。实验采用不同的硫源对脱硫微生物进行了驯化,考察了不同培养基中的微生物的驯化和生长,再将微生物菌种分别接种到煤、黄铁矿和柴油培养基中进行培养。结果表明,在以煤为硫源的培养基中,微生物生长具有较大起伏,不利于菌种的驯化,8d后的脱硫率为10.2%;而在柴油和黄铁矿中培养的微生物则较单一,有利于菌种的驯化,8d后的脱硫率分别为23%和17.4%。The advantage of bio-desulfurization is that it can remove organic sulfur at a low price,and the disadvantage is that the growth of the bacteria is unstable.To increase the desulfurization activity,consistent domestication of bacteria is necessary.An experiment was carried out to domesticate desulfurization bacteria using sulfur of different origin.The growth mechanism of the bacteria from different culture media was investigated,and such bacteria were then inoculated to coal,pyrite and diesel based culture...
