Effects of Combined Stress from Salt and Herbicide on Microbial Remediation of Soil Contaminated by n-Hexadecane and Phenanthrene
文献摘要：
In this study, physicochemical, cluster, and high-throughput sequencing analyses were used to investigate the joint effects of salt and herbicide (glyphosate) stress factors on the microbial remediation of soil contaminated by n-hexadecane and phenanthrene. Based on the soil's physical and chemical properties, differences in microbial quantity and enzyme activities were analyzed among the samples, and how that influenced distribution of soil community structure was focused upon. After 120 days of indoor simulated remediation, the cumulative degradation rate of n-hexadecane decreased by 94.92％ (blank control), 96.96％ (low concentration salt and glyphosate stress group), 65.07％ (high concentration salt and glyphosate stress group), while that of phenanthrene decreased by 87.33％ (blank control), 86.25％ (low concentration salt and glyphosate stress group), 58.45％ (high concentration salt and glyphosate stress group). The combined stress of salt and herbicides was capable of lowering the reduction efficiency of organic matter, total nitrogen, and total phosphorus, and also restricting the growth of microorganisms and enzyme activities. Cluster analysis results indicated that the non- stress group was similar to the low-concentration compound stress group during different remedial period, whereas both of those differed starkly from the high-concentration compound stress group. High-throughput sequencing revealed that the dominant soil bacteria phyla shifted from Firmicutes to Actinobacteria within 120 days of remediation.
