BIOL 360 Lecture 10: Microbial Ecology study notes after test 1
Document Summary
Microbial ecology (after test1: ammensalism- one is neutral, one is harmed, parasitism-host is harmed and predator benefits, ex. Antagonism: antagonism case of antibiosis/ allelopathy, ex. Production of antibiotics: bacteriocin- toxin made by bacteria- produced and released to inhibit growth of competition, allelopathy- plants release chemicals to reduce growth of other plants. Rhizobia- nitrogen fixing bacteria associated with plant roots- live symbiotically with plant roots. The bacteria grows and clogs up the xylem- causes wilting: similar to plant athlerosclerosis (lol, leaf hoppers- suck on the plants- they may have xylella fastidiosa which can infect the plant. The bacteria grows and clogs up the zylem of the plant and the plants wilt. Production of biofilms: starts of as monolayer, more species will come and colonize, then large masses will clump together and change water movement in the interstitial space. Live in eps (green stuff in (c: eps extracellular polymeric substance, any surface with water will grow a biofilm.
