Weight of e. coli ~ 1 picogram [10^-12 g] - the biomass composition. Water is 70% of weight dry weight: Major elemental building blocks of microbial life assume they"re full of protein and rna pay attn to c, n, p [highest in demand] C, h, o, p, k, n, s, ca, fe, mg there are metals* Fe and ____ are enzyme required in relatively large amounts - comprise > 95% of microbial dry weight. We don"t add these to media some are oxidative enzymes used to break down wood required in trace amounts, often supplied in h2o. Dilute nutrient media = higher biodiversity for soil microbes. Most microbes fall into 5 categories pay attn to root, suffix, and presuffix to help identify.
