Document Summary
Composting: decomposition of organic materials: dark, crumbly, earthy smelling soil conditioner, saves money reduces fertilizer and water use, helps environment reduces volume of garbage going to landfills, speeds up natural microbial process, need food for microorganisms, water, aerobic process turn pile, as microorganisms decompose, temperatures increase. Human microbiome project goals: characterize hm more fully by studying samples, determine associations between changes in hm and health/diseases, elsi, provide standardized data, generated taxonomic profiles rrna gene, huge resource describing abundance and variety. Produce enzymes that break proteins, lipids, and carbs into products we can absorb: we need a population of bacteria to help with digestion but it may not always be the same species carrying out the task in another person, microbial diversity varies with state of health or disease, a significant loss of metabolic capabilities appears to occur in microbiomes, the normal uterine is sterile this idea is being challenged.
