In this essay, the writer points out that soil bacteria control the course of nitrogen, carbon, and phosphorus through ecosystems. Soil samples were taken from established sites, which have undergone existing long-term manipulations of temperature, nutrient and light availability. The writer discusses that the soil samples were found to contain bacteria through testing and are being studied to determine whether treatments known to affect plant communities also affect soil microbial biomass, activity, gene expression, and community composition as measured by terminal restriction fragment length polymorphisms.
From the Paper:"Soil is an intricate and active biological system, and at times it is difficult to determine the composition of microbial communities in soil. Yet, the study requires a wide variety of methods, which includes methods of extracting DNA from soil suitable for PCR amplification to monitor GM rhizobia and extracting mRNA directly from soil to use in gene expression studies. Hydrocarbons seem to be a contaminated factor when isolating the soil samples in determining bacteria characterization. "Bacteria were isolated from contaminated soil with the media indicating several homolog similarities (researched the possibility of several bacteria names through DP database as determined by the program SIMILARITY_RANK (10)"."
