Microbial activity is important and shapes the health of individual organisms and entire ecosystems. Metagenomes are random samples of the microbial genomes within an environment and are constructed to explore variations in microbial activities. Multivariate statistical analysis of the metagenome sequences provides a description of the metabolic processes that are important for the growth and survival of the microbes in any given environment. Using combinations of multivariate statistical methods including Random Forests variable selection and canonical discriminant analysis, results from the SDSU Summer REUT program are presented. Results showed that the metabolic profile provided by metagenomes are highly accurate in distinguishing the activity of microbial communities from different environments.
