摘要:
摘要考察了不同烷烃底物和温度、酸度、盐度等环境条件对两株铜绿假单胞菌接触烷烃方式和降解活性的影响.结果表明,微生物接触烷烃的两种方式——直接接触方式和乳化接触方式同时存在于菌体降解烷烃过程中且受底物和环境条件的影响.底物烷烃碳数的增加对菌株两种接触方式降解烷烃都有利,而盐度增加对它们都不利;高温、偏碱性环境以及延长降解时间有利于菌体以乳化方式降解烷烃;低温、中性溶液环境有利于菌体以直接接触方式降解烷烃.图4参12
Abstract:
Abstract Two Pseudomonas aeruginosa strains, S and Y, were used here to study the effects of n alkanes substrate and environmental conditions, including temperature, pH and salinity on microbial hydrocarbon access modes and degrading ability. The results showed that both microbial hydrocarbon access modes, that is, direct contact mode and biosurfactantmedium mode, existed in the petroleum hydrocarbon degradation process by the same strain and were affected by the substrate and environmental factors. It was found that the uptake of longchain nalkanes was improved by the two modes, but high salinity was disadvantageous to the alkane uptake process in either of the modes. High temperature, alkaline solution and long degradation time were advantageous to utilization of nhexadecane substrate by biosurfactantmedium mode, while low temperature and moderate pH were more suitable for hydrocarbon biodegradation by direct contact mode.
