BIOL 3200 Lecture Notes - Lecture 16: Acidobacteria, Geosmin, Azolla
Document Summary
Produce antivirals, fungals, bacterials, thrombotics, immunomodi es, anti- tumor drugs, enzyme inhibitors, insecticides, herbicides, fungicides can form antibiotics (amminoglycolosides, chloramphenicol, macrolides, tetraclycines) Frankia: with plants (symbiotic); can x nitrogen; frankia would like to have sugars from plants; show up in soils and water. Can be colonial or lamentous (can move by gliding- lack agella) Ephtyic: cyanotalpha (chava) which can x nitrogen. Holds gas vesicles (made by protein sheets , not true membrane baena vesicles) Have a 2nd membrane that makes them appear to be gram negative. Form pink red colonies (because of carotenoids pigments) Can survive in vacuum of space and extreme cold and heat. Pumps: pump certain proteins and protons; maintain internal neutral environment. Anaerobic, rod, aquatic environments often found in deep waters (aquaphores) Exposed to types of iron which they use as electron acceptors (important in geochemical cycles) Found in peats bogs, sphagnum, and sugars which feel the organisms. Made up of a sheath called toga.
