SLSC 398 Lecture Notes - Lecture 36: Plasmid, Cyanobacteria, Cation-Exchange Capacity
Document Summary
Review questions: ph questions - which of the elements are going to precipitate and availability of ions from metabolic pathways when there is a shift in ph. The ones that will stay in the soil solution. Siderophore - molecules that bind fe2+ and there not degraded by bacteria enzymes so they linger long enough to bind any fe2+ that would be in the soil solution. Bacteria to transport the molecules back into the cytoplasm. Clay and minerals and precipitate will come into the solution, if you have fe2+ and phosphate in the solution who get to use it - the bacteria and the roots will want to take it up. If they formed the bio lm the bacteria would be the only ones taking up this nutrients. Heavy metals come into solution from clays at acidic ph, 5. 5 5 and lower more and more of the metals will come into solution because the clays are dissolving.
